Does Internet-based guided-self-help for depression cause harm? An individual participant data meta-analysis on deterioration rates and its moderators in randomized controlled trials

Therapists' experiences of negative effects in intensive short-term dynamic psychotherapy: A qualitative interview study

OBJECTIVE

Negative effects of psychotherapy are a broad term that encompasses events such as non-response, deterioration, and novel symptoms. The aim of the present study was to explore experiences with negative effects among clinicians working within an intensive short-term dynamic psychotherapy (ISTDP) framework.

METHOD

Eight ISTDP clinicians consented to participate and were interviewed using semi-structured video interviews. Data were transcribed and analyzed using a reflexive thematic analysis framework.

RESULTS

The thematic analysis resulted in five themes. Overall, the clinicians found it difficult to define negative effects, but that negative effects, regardless of cause, could be used therapeutically. Inaccurate assessment was seen as the main cause of negative effects. Other themes concerned the connection between dropout and negative effects, patient feedback, and the ISTDP community's relationship to negative effects.

CONCLUSIONS

The results are largely in line with qualitative studies of CBT clinicians' views of negative effects although clinicians in the present study emphasized more strongly the therapeutic potential of these events. The research field could be further improved by using mixed-method designs while including both patients and therapists.

A systematic review of predictors and moderators of treatment outcomes in internet- and mobile-based interventions for depression

This systematic review aimed to synthesize evidence on predictors and moderators of treatment outcomes in internet- and mobile-based interventions (IMIs) for depression, informing personalized care. A systematic search across PubMed, PsycInfo, and Cochrane yielded 33,002 results. Two reviewers independently performed screening, data extraction, risk of bias assessment, and methodological quality evaluation. Fifty-eight single studies (m = 466 analyses) focusing on baseline-predictors (59.7 %, m = 278), process-predictors (16.5 %, m = 77), and moderators (21.9 %, m = 102), and six individual patient data meta-analyses (m = 93) were included. Only 24.0 % (m = 112/466) of analyses in single studies and 15.1 % (m = 14/93) in individual patient data meta-analyses were significant. Evidence from single studies was rated as insufficient for all variable categories with only 2 out of 40 categories showing >50 % significant results. Baseline depression severity had the strongest predictive value with higher scores linked to better outcomes followed by variables indicative for the course-of-change. Other frequently analyzed and potentially relevant variables with significant results were adherence, age, educational level, ethnicity, relationship status, treatment history, and behavioral variables. More high quality quantitative studies with sufficient power are essential to validate and expand findings, identifying predictors and moderators specifically relevant in IMIs to explain differential treatment effects.

Adverse Events of Psychological Interventions: Definitions, Assessment, Current State of the Research and Implications for Research and Clinical Practice

BACKGROUND

The effectiveness of psychological interventions is undisputed. But while in other fields of health care the safety of interventions is studied alongside effectiveness, adverse events (AEs) have only recently been assessed in clinical studies of psychological interventions. This critical review summarizes the definition, assessment and current research status of AEs of psychological interventions.

SUMMARY

AEs are defined as any untoward event or unfavorable change that occurs in the course of a psychological intervention. AEs that are caused by the intervention can be classified into side effects of correctly applied treatment, malpractice (i.e., incorrectly applied treatment) and unethical conduct (e.g., sexual abuse). Ideally, they are assessed by independent raters or alternatively by self-report questionnaires that should also cover serious adverse events (SAEs, e.g., suicide attempts or self-injurious behaviors). About 1 to 2 in 3 patients report at least 1 AE and results of meta-analyses suggest that treatments might differ in frequency and/or severity of AE and in treatment acceptability (measured as dropout rates).

KEY MESSAGES

Measures of AEs and SAEs as well as more nuanced descriptions of dropout should be included in all clinical studies of psychological interventions. If this happens, we might learn that psychological interventions differ with respect to AEs, SAEs and acceptability. As many psychological interventions are about equally effective, they might one day be chosen based on differences in their safety profile rather than their differential effectiveness. Ideally, reducing AEs might also lead to more effective interventions.

Outcomes of transdiagnostic internet-delivered cognitive behavioural therapy tailored to public safety personnel: A longitudinal observational study

First responders and other public safety personnel (PSP) experience high rates of mental health problems and face barriers to accessing mental healthcare. Internet-delivered cognitive behavioural therapy (ICBT) is an effective and accessible treatment for various mental health concerns. Canadian PSP report favorable attitudes toward ICBT, and preliminary outcomes demonstrate that they benefit from it. Expanding on this research, the current study consisted of a longitudinal observational study of 560 Canadian PSP who participated in ICBT. It was designed to assess the longer term effectiveness of ICBT and moderators of outcomes by gender, linguistic and occupational group, and years of occupational experience. We evaluated symptom change at 8, 26, and 52 weeks post-enrollment, and results among PSP who had elevated clinical scores, showed large reductions (Hedges' g) in symptoms of depression (g = 1.3), anxiety (g =1.48), posttraumatic stress (g =1.24), panic (g =1.19), and anger (g =1.07) and moderate reductions in symptoms of social anxiety (g =.48-.56). Moderator analyses revealed modest differences in pre-treatment symptoms among certain groups but no group differences in symptom change over time. Clients showed good completion of treatment materials and reported high treatment satisfaction. The results suggest further study of ICBT tailored to PSP is warranted, including evaluating ICBT tailored for PSP in other countries.

Recording harms in randomized controlled trials of behavior change interventions: a scoping review and map of the evidence

OBJECTIVES

Randomized controlled trials evaluate diverse interventions. This can include medical interventions such as drugs or surgical procedures, or behavior change interventions (BCIs) that aim to change a habit, belief, or attitude to improve health, for example, healthy eating, psychological wellbeing. Harms are often recorded poorly or inconsistently within randomized controlled trials of BCIs. This scoping review aimed to collate and describe literature on categories, definitions, and mechanisms of harms from BCIs; methods of identifying plausible harms; and recommendations for recording harms.

STUDY DESIGN AND SETTING

A scoping review was conducted. Three databases (MEDLINE, PsycINFO, and CINAHL) were searched. Reference list checking and citation searching were performed. Articles were included if they discussed (1) interventions that aimed to modify behavior, (2) categories or mechanisms of harms, and (3) methods or recommendations for recording harms. All research designs were included. One reviewer reviewed titles, abstracts, and full texts; queries were checked with another reviewer. Data were extracted and synthesized descriptively by one reviewer and checked by another reviewer. A thematic map was constructed to summarize the review findings. Harms described from specific BCIs were identified, and examples were selected and summarized.

RESULTS

The review included 37 articles. Nineteen of 37 articles contributed to a thematic review. Three articles described categories of harms; categories of harm included physical, psychological, group and social interactions, cultural, equity, opportunity cost, environmental, and economic. Seven articles included mechanisms or underlying factors for harms including feelings of failure leading to shame or stigma, and group interventions enabling knowledge exchange on unhealthy behaviors. Twelve articles provided recommendations for recording harms, including taking a proportionate approach by focusing on the most plausible and important harms, collecting different perspectives on whether harms had occurred (eg, caregivers and family members), and using qualitative research methods to identify harms. One article described a three-step method to identify plausible harms from an intervention, and six articles supported aspects of the method. Eighteen of 37 articles contributed to a review which collated harms arising from specific interventions, for example, a peer support intervention in inflammatory bowel disease caused distressing conversations which might lead to anxiety and confrontation with a possible negative future.

CONCLUSION

BCIs can cause harm. This review identified categories and proposed mechanisms of harms, as well as methods and recommendations for identifying and recording harms in BCIs for inclusion in forthcoming recommendations.

Internet- and mobile-based anxiety and depression interventions for children and adolescents: efficacy and negative effects - a systematic review and meta-analysis

Mental disorders, most commonly anxiety disorders and fourth most common depression, are prevalent in children and adolescents. Internet- and mobile-based interventions might represent a scalable approach to improve mental health care, however, evidence so far is inconclusive and systematic reports on negative effects are missing. Four data-bases were searched for randomized controlled trials evaluating internet- and mobile-based interventions (IMIs) targeting anxiety disorders or depression in children and adolescents up to 18 years exhibiting clinically relevant symptoms. Meta-analytic evaluations were conducted in comparison to active and passive control groups, furthermore, pre-defined sub-groups were explored and reported negative effects examined. Pooled estimates showed a moderate positive effect for IMIs targeting anxiety disorders compared to passive control groups (g = -0.69; CI -0.94 to -0.45; k = 8; n = 559; p ≤ 0,001), but not for depression. Pooled estimates compared to active control groups remained non-significant. Subgroup analyses were largely omitted due to an insufficient number of trials or were non-significant. Negative effects were mainly reported as drop-out rates and (non)-response rates, while additional negative effects, such as deterioration rates or the development of additional symptoms, were reported by only one third of included studies. The focus on children and adolescents with clinically relevant symptoms allowed the present findings to complement previous work, however, the limited amount of trials hindered many planned comparisons. The overview of reported negative effects highlighted that negative effects are being neglected in the majority of RCTs. Hence, in the future RCTs should include more information about potential negative effects, at best a combination of quantitative and qualitative information. Open Science Framework (osf.io/ch5nj).

Symptom Reduction and Engagement in a Cognitive-Behavioral Mobile Phone App: A Study of User Profiling to Determine Prognostic Indicators

OBJECTIVE

We investigated the presence of latent transition profiles in a sample of users of a cognitive-behavioral mental health app for the general population. Users' baseline characteristics were used as predictors of the profiles. The role of engagement with the app in the transition profiles was examined.

METHOD

A total of 541 users completed the Patient Health Questionnaire-9 and the General Anxiety Disorder-7 when started using the app and 30 days after. Random-Intercept Latent Transition Analysis was implemented to identify users' profiles and transition patterns as classes. The age of the users and the Emotional Self-Awareness Scale-Revised (ESAS-R) were used as predictors of class membership at baseline. The Homework Rating Scale-Mobile Application (HRS-MA; as a measure of engagement) was used as a predictor of class membership at 30 days of app use.

RESULTS

A 3-class solution was obtained according to the severity of symptoms (from mild to moderately severe). Age and ESAS-R predicted class membership initially; the higher the age and ESAS-R, the higher the probability of starting using the app with lower distress levels. The HRS-MA predicted class membership at 30 days of app use; the higher the engagement for more symptomatic and younger users, the higher the probability of improvement. However, older users tended to engage less.

CONCLUSION

Our findings underpin the relevance of easily accessible digital interventions for young adults with mild to moderate mental health problems. Further studies and developments are required to enhance these apps for older cohorts.

What to do when the unwanted happens? Negative event management in studies on internet- and mobile-based interventions for youths and adults with two case reports

Background

Despite severely burdened individuals, often being excluded from research studies on internet- and mobile-based interventions (IMIs), negative events (NEs) including suicidal thoughts and behaviors (STBs) can still occur during a trial. NEs require monitoring and adequate safety measures. However, study protocols frequently lack comprehensive descriptions of procedures for managing NEs.

Aims

This study aimed to illustrate the assessment, monitoring, and procedures for addressing NEs in two studies on IMIs in adults and youth using case reports, to identify strengths and weaknesses of the NE management approaches, and to derive key learnings and recommendations.

Methods

Two case reports were drawn from two distinct IMI studies. The first study, PSYCHOnlineTHERAPY, evaluates the combination of an IMI with on-site psychotherapy for anxiety and depressive disorders in adults (adult blended study). The second study evaluates a standalone, therapist-guided IMI for post-traumatic stress disorder (PTSD) in youth (youth standalone study). Potential NEs were predefined depending on the study sample. The case studies thoroughly document the systematic recording and ongoing monitoring of NEs through self-report and observer-based assessments during the interventions. The cases illustrate a variety of NE management strategies, including automated and personalized approaches, adapted to the specific nature and severity of the NEs. The NE management approaches are visualized using decision trees.

Results

In the adult blended case study, online questionnaires detected STBs and triggered automated support information. As on-site therapy had already ended, a telephone consultation session allowed for the identification and discussion of the heightened intensity of suicidal thoughts, along with the development of specific additional help options. In the youth standalone case study, heightened tension in an adolescent with PTSD during trauma processing could be addressed in a telephone therapeutic session focusing on resource activation and emotion regulation. The referral to on-site treatment was supported. Overall, advantages of the NE management included automated procedures, multimodal assessment of a wide range of NEs, and standardized procedures tailored to different severity levels. Weaknesses included the use of single-item assessments for STBs and lack of procedures in case of deterioration or nonresponse to treatment.

Conclusion

This study provides practical insights and derives key learnings and recommendations regarding the management of NEs in different IMI contexts for both adults and youth.

Are web-based stress management interventions effective as an indirect treatment for depression? An individual participant data meta-analysis of six randomised trials

QUESTION

Depression is highly prevalent and associated with numerous adverse consequences for both individuals and society. Due to low uptake of direct treatment, interventions that target related, but less stigmatising problems, such as perceived stress, have emerged as a new research paradigm.This individual participant data (IPD) meta-analysis examines if a web-based stress management intervention can be used as an 'indirect' treatment of depression.

STUDY SELECTION AND ANALYSIS

Bayesian one-stage models were used to estimate pooled effects on depressive symptom severity, minimally important improvement and reliable deterioration. The dose-response relationship was examined using multilevel additive models, and IPD network meta-analysis was employed to estimate the effect of guidance.

FINDINGS

In total, N=1235 patients suffering from clinical-level depression from K=6 randomised trials were included. Moderate-to-large effects were found on depressive symptom severity at 7 weeks post-intervention (d=-0.65; 95% credibility interval (CrI): -0.84 to -0.48) as measured with the Center for Epidemiological Studies' Depression Scale. Effects were sustained at 3-month follow-up (d=-0.74; 95% CrI: -1.01 to -0.48). Post-intervention symptom severity was linearly related to the number of completed sessions. The incremental impact of guidance was estimated at d=-0.25 (95% CrI: -1.30 to 0.82), with a 35% posterior probability that guided and unguided formats produce equivalent effects.

CONCLUSIONS

Our results indicate that web-based stress management can serve as an indirect treatment, yielding effects comparable with direct interventions for depression. Further research is needed to determine if such formats can indeed increase the utilisation of evidence-based treatment, and to corroborate the favourable effects for human guidance.

Effect of self-help interventions on psychological, glycemic, and behavioral outcomes in patients with diabetes: A meta-analysis of randomized controlled trials

BACKGROUND

Self-help interventions are beneficial for patients with diabetes; however, related studies have reported conflicting results. To date, no review has examined the effect of self-help interventions on diabetes outcomes.

OBJECTIVES

To systematically evaluate the effects of self-help interventions on psychological, glycemic, and behavioral outcomes in patients with diabetes.

DESIGN

A systematic review and meta-analysis of randomized controlled trials.

METHODS

Five databases-PubMed, CINAHL, Embase, PsycINFO, and ClinicalTrials.gov-were searched from 1996, 1937, 1947, 1887, and 2000, respectively, to 2 June 2023. Studies that employed a randomized controlled trial design, enrolled adults with diabetes, implemented a self-help intervention as the main or an additional intervention, and reported the outcomes of interest were included. Studies providing self-help interventions to patients with gestational diabetes or pregnant women were excluded. The primary outcomes were diabetes distress, depression, and anxiety, and the secondary outcomes were glycemic and behavioral outcomes (self-management behavior, self-efficacy, and quality of life). Hedges' g and the associated 95 % confidence interval (CI) were calculated using a random-effects model to obtain the pooled estimates of short-, mid-, and long-term effects of self-help interventions. Heterogeneity was explored using I2 and Q statistics, and moderator analysis was performed to identify the sources of heterogeneity.

RESULTS

Of 17 eligible studies, 16 provided data for meta-analysis. We included 3083 patients with diabetes; the majority were women (61.95 %), and their average age was 55.13 years. Self-help interventions exerted significant short-term effects on diabetes distress (g = -0.363; 95 % CI = -0.554, -0.173), depression (g = -0.465; 95 % CI = -0.773, -0.156), anxiety (g = -0.295; 95 % CI = -0.523, -0.068), glycosylated hemoglobin level (g = -0.497; 95 % CI = -0.791, -0.167), self-efficacy (g = 0.629; 95 % CI = 0.060, 1.197), and quality of life (g = 0.413; 95 % CI = 0.104, 0.721; g = 0.182; 95 % CI = 0.031, 0.333; and g = 0.469; 95 % CI = 0.156, 0.783 for overall, physical, and mental domains, respectively). We also noted significant mid-term effects of self-help interventions on diabetes distress (g = -0.195; 95 % CI = -0.374, -0.016), self-management behavior (g = 0.305; 95 % CI = 0.155, 0.454), and overall quality of life (g = 0.562; 95 % CI = 0.315, 0.810). The certainty of evidence ranged from high to very low certainty for the measured outcomes.

CONCLUSIONS

Self-help interventions may have some positive effects on diabetes distress, anxiety, self-management behavior, and quality of life.

REGISTRATION

TWEETABLE ABSTRACT

This meta-analysis demonstrated that self-help interventions might improve psychological and behavioral outcomes in patients with diabetes.

Is Self-Help Dangerous? Examination of Adverse Effects of a Psychological Internet-Based Self-Help Intervention for Body-Focused Repetitive Behavior (Free From BFRB)

Despite the proven effectiveness of psychotherapy for psychiatric disorders, adverse events or unwanted effects may occur. Unwanted effects, however, are rarely assessed. In self-help interventions, which usually are not supported by a therapist, such effects have received even less attention even though special caution is needed regarding unwanted effects such as those related to misapplication. For the present study, we present the newly developed Positive and Negative Effects of Psychotherapy Scale for Internet-Based Intervention (PANEPS-I) and examine possible unwanted effects of an internet-based self-help intervention in individuals with body-focused repetitive behaviors (BFRBs), aggregating three different techniques: habit reversal training (HRT), decoupling (DC), and decoupling in sensu (DC-is). Some HRT users have expressed concern that the suppression of the problematic behavior could lead to rebound effects, but this has not been examined rigorously. Following baseline assessment, 141 participants with at least one BFRB were randomly assigned to two intervention groups that differed only with respect to the delivery mode (video, manual); the content was the same. After 6 weeks, a post-assessment was conducted. Unwanted effects were assessed using the PANEPS-I. A total of 70% of the participants (both treatment groups combined) reported at least one positive effect of the intervention. Negative effects were reported by 14-92% of participants, depending on the effect. The highest agreement rates were found for "no positive goal orientation" (52.5%), "did not address personal problems" (48.8%), "time/performance pressure" (20.9%), shame (16.3%), and concerns about data privacy (14.3%). Participants in the manual intervention group reported unethical procedures (e.g., data privacy concerns) more often (Cohen's d = .44) than those in the video intervention group. Responders reported more positive effects and nonresponders more malpractice (|d| = .80, .54, respectively). HRT users (self-report) showed no significant differences compared to nonusers regarding negative effects. Stepwise hierarchical regression analyses indicated a dose-response relationship for reported positive effects and malpractice. Side effects may occur in any kind of intervention. Usage of HRT did not lead to more reported negative effects compared to nonusage. To improve the quality and effectiveness and ensure the safety of the user, especially those using digital self-help interventions, it is important to regularly assess unintended effects since there is no supervision of the patient in unguided self-help interventions.

What Do We Know About Depression Among Youth and How Can We Make Progress Toward Improved Understanding and Reducing Distress? A New Hope

This paper summarizes many findings about depression among children and adolescents. Depression is prevalent, highly distressing, and exerts considerable burden worldwide. Rates surge from childhood through young adulthood and have increased over the last decade. Many risk factors have been identified, and evidence-based interventions exist targeting mostly individual-level changes via psychological or pharmacological means. At the same time, the field appears stuck and has not achieved considerable progress in advancing scientific understanding of depression's features or delivering interventions to meet the challenge of youth depression's high and growing prevalence. This paper adopts several positions to address these challenges and move the field forward. First, we emphasize reinvigoration of construct validation approaches that may better characterize youth depression's phenomenological features and inform more valid and reliable assessments that can enhance scientific understanding and improve interventions for youth depression. To this end, history and philosophical principles affecting depression's conceptualization and measurement are considered. Second, we suggest expanding the range and targets of treatments and prevention efforts beyond current practice guidelines for evidence-based interventions. This broader suite of interventions includes structural- and system-level change focused at community and societal levels (e.g., evidence-based economic anti-poverty interventions) and personalized interventions with sufficient evidence base. We propose that by focusing on the FORCE (Fundamentals, Openness, Relationships, Constructs, Evidence), youth depression research can provide new hope.

An ACT self-help intervention for adults with a visible difference in appearance: A pilot feasibility and acceptability randomized controlled study

Individuals living with a visible difference in appearance experience high levels of social anxiety, yet self-help interventions for this heterogeneous population are not available. We conducted a pilot trial of a novel Acceptance and Commitment Therapy (ACT) based self-help intervention.Individuals with anxiety about having a visible difference in appearance (n = 284) were randomized to an ACT-based four-week intervention (n = 145) or a waitlist control condition (n = 139). We collected pre and follow-up (four-weeks after the completion of the intervention) data. Primary outcomes included social anxiety and impairments in functioning. Psychological flexibility (PF) was also examined. ANCOVAs, controlling for pre scores, indicated significant improvements in functioning by the intervention group. No significant differences were observed for anxiety and PF between conditions at follow-up. Drop out was 68% for the intervention and 41% for the control group, with no differences in the groups in age, origin, gender, or type of visible difference. Participants in the intervention group found the intervention almost equally, useful (77%) and helpful (73%). An ACT-based self-help intervention can alleviate distress related to visible difference in appearance. More sophisticated designs are needed now, to collect idiographic and longitudinal data and examine personalized changes across time in this population.

Effects of a Self-Guided Transdiagnostic Smartphone App on Patient Empowerment and Mental Health: Randomized Controlled Trial

BACKGROUND

Mental disorders impact both individuals and health systems. Symptoms and syndromes often remain undetected and untreated, resulting in chronification. Besides limited health care resources, within-person barriers such as the lack of trust in professionals, the fear of stigmatization, or the desire to cope with problems without professional help contribute to the treatment gap. Self-guided mental health apps may support treatment seeking by reducing within-person barriers and facilitating mental health literacy. Digital mental health interventions may also improve mental health related self-management skills and contribute to symptom reduction and the improvement of quality of life.

OBJECTIVE

This study aims to investigate the effects of a self-guided transdiagnostic app for mental health on help seeking, reduced stigma, mental health literacy, self-management skills, mental health symptoms, and quality of life using a randomized controlled design.

METHODS

Overall, 1045 participants (recruited via open, blinded, and web-based recruitment) with mild to moderate depression or anxiety-, sleep-, eating-, or somatization-related psychopathology were randomized to receive either access to a self-guided transdiagnostic mental health app (MindDoc) in addition to care as usual or care as usual only. The core features of the app were regular self-monitoring, automated feedback, and psychological courses and exercises. The coprimary outcomes were mental health literacy, mental health-related patient empowerment and self-management skills (MHPSS), attitudes toward help seeking, and actual mental health service use. The secondary outcomes were psychopathological symptom burden and quality of life. Data were collected at baseline and 8 weeks and 6 months after randomization. Treatment effects were investigated using analyses of covariance, including baseline variables as predictors and applying multiple imputation.

RESULTS

We found small but robust between-group effects for MHPSS (Cohen d=0.29), symptoms burden (Cohen d=0.28), and quality of life (Cohen d=0.19) 8 weeks after randomization. The effects on MHPSS were maintained at follow-up. Follow-up assessments also showed robust effects on mental health literacy and preliminary evidence for the improvement of help seeking. Predictors of attrition were lower age and higher personality dysfunction. Among the non-attritors, predictors for deterioration were less outpatient treatment and higher initial symptom severity.

CONCLUSIONS

A self-guided transdiagnostic mental health app can contribute to lasting improvements in patient empowerment. Symptoms of common mental disorders and quality of life improved faster in the intervention group than in the control group. Therefore, such interventions may support individuals with symptoms of 1 or more internalizing disorders, develop health-centered coping skills, prevent chronification, and accelerate symptom improvement. Although the effects for individual users are small and predictors of attrition and deterioration need to be investigated further, the potential public health impact of a self-guided intervention can be large, given its high scalability.

Improving mental well-being in psychocardiology-a feasibility trial for a non-blended web application as a brief metacognitive-based intervention in cardiovascular disease patients

Background

Many patients with cardiovascular disease also show a high comorbidity of mental disorders, especially such as anxiety and depression. This is, in turn, associated with a decrease in the quality of life. Psychocardiological treatment options are currently limited. Hence, there is a need for novel and accessible psychological help. Recently, we demonstrated that a brief face-to-face metacognitive therapy (MCT) based intervention is promising in treating anxiety and depression. Here, we aim to translate the face-to-face approach into digital application and explore the feasibility of this approach.

Methods

We translated a validated brief psychocardiological intervention into a novel non-blended web app. The data of 18 patients suffering from various cardiac conditions but without diagnosed mental illness were analyzed after using the web app over a two-week period in a feasibility trial. The aim was whether a non-blended web app based MCT approach is feasible in the group of cardiovascular patients with cardiovascular disease.

Results

Overall, patients were able to use the web app and rated it as satisfactory and beneficial. In addition, there was first indication that using the app improved the cardiac patients' subjectively perceived health and reduced their anxiety. Therefore, the approach seems feasible for a future randomized controlled trial.

Conclusion

Applying a metacognitive-based brief intervention via a non-blended web app seems to show good acceptance and feasibility in a small target group of patients with CVD. Future studies should further develop, improve and validate digital psychotherapy approaches, especially in patient groups with a lack of access to standard psychotherapeutic care.

Who benefits from guided internet-based interventions? A systematic review of predictors and moderators of treatment outcome

To our knowledge, no systematic review has been conducted on predictors or moderators of treatment outcome across diagnoses in guided internet-based interventions (IBIs) for adults. To identify who benefits from this specific format and therein inform future research on improving patient-treatment fit, we aimed to aggregate results of relevant studies. 2100 articles, identified by searching the databases PsycInfo, Ovid Medline, and Pubmed and through snowballing, were screened in April/May 2021 and October 2022. Risk of bias and intra- and interrater reliability were assessed. Variables were grouped by predictor category, then synthesized using vote counting based on direction of effect. N = 60 articles were included in the review. Grouping resulted in 88 predictors/moderators, of which adherence, baseline symptoms, education, age, and gender were most frequently assessed. Better adherence, treatment credibility, and working alliance emerged as conclusive predictors/moderators for better outcome, whereas higher baseline scores predicted more reliable change but higher post-treatment symptoms. Results of all other predictors/moderators were inconclusive or lacked data. Our review highlights that it is currently difficult to predict, across diagnoses, who will benefit from guided IBIs. Further rigorous research is needed to identify predictors and moderators based on a sufficient number of studies. PROSPERO registration: CRD42021242305.

Digital Therapeutics as a New Therapeutic Modality: A Review from the Perspective of Clinical Pharmacology

The promise of transforming digital technologies into treatments is what drives the development of digital therapeutics (DTx), generally known as software applications embedded within accessible technologies-such as smartphones-to treat, manage, or prevent a pathological condition. Whereas DTx solutions that successfully demonstrate effectiveness and safety could drastically improve the life of patients in multiple therapeutic areas, there is a general consensus that generating therapeutic evidence for DTx presents challenges and open questions. We believe there are three main areas where the application of clinical pharmacology principles from the drug development field could benefit DTx development: the characterization of the mechanism of action, the optimization of the intervention, and, finally, its dosing. We reviewed DTx studies to explore how the field is approaching these topics and to better characterize the challenges associated with them. This leads us to emphasize the role that the application of clinical pharmacology principles could play in the development of DTx and to advocate for a development approach that merges such principles from development of traditional therapeutics with important considerations from the highly attractive and fast-paced world of digital solutions.

Psychological treatment of depression: A systematic overview of a 'Meta-Analytic Research Domain'

BACKGROUND

Over the past 16 years, we have developed a 'Meta-analytic Research Domain' (MARD) of all randomized trials of psychological treatments of depression. A MARD is a living systematic review of a research field, that cannot be otherwise covered by one (network) meta-analysis and includes multiple PICOs. In this paper we give an overview of the findings of this MARD.

METHODS

A narrative review of the results of the 118 meta-analyses on psychotherapies for depression that were published within our MARD.

RESULTS

Most research has been conducted on cognitive-behavioral therapy (CBT), but several other psychotherapies are also effective, with few differences between therapies. They can be effectively delivered in individual, group, telephone and guided self-help format and are effective in many different target groups and across different age groups, although the effects are significantly smaller in children and adolescents. Psychotherapies have comparable effects as pharmacotherapy at the short term but are probably more effective at the longer term. Combined treatment is more effective than either psychotherapy or pharmacotherapy alone at the short, but also at the longer term.

LIMITATIONS

We did not summarize all published meta-analyses (protocols, methodological studies) and have not compared our results to those found in other meta-analyses on comparable subjects.

CONCLUSION

Psychotherapies can contribute considerably to a reduction of the disease burden of depression. MARDs are an important next step in the aggregation of knowledge from randomized controlled trials in psychological treatments of depression as well as in other healthcare sectors.

Therapists' experiences with providing guided internet-delivered cognitive behavioral therapy for patients with mild and moderate depression: a thematic analysis

Introduction

Guided internet-delivered therapy has shown promising results for patients with mild and moderate depressive disorder, but several challenges with the format have been reported. The aim of this qualitative study was to investigate therapists' experiences providing guided internet-delivered cognitive behavioral therapy for patients with mild and moderate depression.

Material and methods

Twelve therapists were interviewed, and the interviews were analyzed using reflexive thematic analysis.

Results and conclusion

Three themes were created: (1) For the right person, at the right time. This theme is about therapists' experiences appointing patients to the program. It is challenging to predict which patients will benefit from it, and it is not the right option for all patients. (2) It is not like chatting on Facebook. The second theme was about the experiences with demands on clinics, therapists and patients that must be considered. The internet-delivered treatment should not be viewed as a simple treatment option, and the value of having contact with the patients during treatment was emphasized. (3) It is like a railroad, but without the switches. This theme was about the experiences with how the treatment content was conveyed to the patients, how the therapists expressed concerns with the usability of the program and the reported need for more possibilities in tailoring treatment for each patient.

Individual participant data systematic review and meta-analysis of randomised controlled trials assessing adult mindfulness-based programmes for mental health promotion in non-clinical settings

Introduction

Mindfulness-based programmes (MBPs) are widely used to prevent mental ill-health that is becoming the leading global cause of morbidity. Evidence suggests beneficial average effects but wide variability. We aimed to confirm the effect of MBPs on psychological distress, and to understand whether and how baseline distress, gender, age, education, and dispositional mindfulness modify the effect of MBPs on distress among adults in non-clinical settings.

Methods

We conducted a pre-registered systematic review and individual participant data (IPD) meta-analysis (PROSPERO CRD42020200117). Thirteen databases were searched in December 2020 for randomised controlled trials satisfying a quality threshold and comparing in-person, expert-defined MBPs in non-clinical settings with passive control groups. Two researchers independently selected, extracted, and appraised trials using the revised Cochrane Risk-of-Bias Tool (RoB2). Anonymised IPD of eligible trials were sought from collaborating authors. The primary outcome was psychological distress (unpleasant mental or emotional experiences including anxiety and depression) at 1 to 6 months after programme completion. Data were checked and imputed if missing. Pairwise, random-effects, two-stage IPD meta-analyses were conducted. Effect modification analyses followed a within-studies approach. Public and professional stakeholders were involved in the planning, conduct and dissemination of this study.

Results

Fifteen trials were eligible, 13 trialists shared IPD (2,371 participants representing 8 countries, median age 34 years-old, 71% women, moderately distressed on average, 20% missing outcome data). In comparison with passive control groups, MBPs reduced average distress between one- and six-months post-intervention with a small to moderate effect size (standardised mean difference (SMD) -0.32; 95% confidence interval (CI) -0.41 to -0.24; p-value < 0.001; 95% prediction interval (PI) -0.41 to -0.24 (no heterogeneity)). Results were robust to sensitivity analyses, and similar for the other psychological distress time point ranges. Confidence in the primary outcome result is high. We found no clear indication that this effect is modified by baseline psychological distress, gender, age, education level, or dispositional mindfulness.

Conclusions

Group-based teacher-led MBPs generally reduce psychological distress among community adults who volunteer to receive this type of intervention. More research is needed to identify sources of variability in outcomes at an individual level.

Exploring the Safety of a General Digital Mental Health Intervention to Effect Symptom Reduction among Individuals with and without Suicidal Ideation: A Secondary Analysis

Trials of digital mental health interventions (DMHIs) often exclude individuals with suicide-related thoughts and behaviors precluding an understanding of whether DMHIs for affective disorders are safe for, and perform similarly within, this high-risk group. We explore the safety and performance of a DMHI for depression in participants with and without suicidal ideation (SI) at baseline. Three hundred and one participants were included in this secondary data analysis from a trial of an 8-week DMHI comprising 14 smartphone apps. We found that SI decreased across the study among participants with baseline SI and that baseline SI status did not attenuate depression treatment effects. Through a case study of the IntelliCare platform, we find that DMHIs for general affective disorders can be safe.

Depression and Suicide Risk Screening: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

Importance

Depression is common and associated with substantial burden. Suicide rates have increased over the past decade, and both suicide attempts and deaths have devastating effects on individuals and families.

Objective

To review the benefits and harms of screening and treatment for depression and suicide risk and the accuracy of instruments to detect these conditions among primary care patients.

Data Sources

MEDLINE, PsychINFO, Cochrane library through September 7, 2022; references of existing reviews; ongoing surveillance for relevant literature through November 25, 2022.

Study Selection

English-language studies of screening or treatment compared with control conditions, or test accuracy of screening instruments (for depression, instruments were selected a priori; for suicide risk, all were included). Existing systematic reviews were used for treatment and test accuracy for depression.

Data Extraction and Synthesis

One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Findings were synthesized qualitatively, including reporting of meta-analysis results from existing systematic reviews; meta-analyses were conducted on original research when evidence was sufficient.

Main Outcomes and Measures

Depression outcomes; suicidal ideation, attempts, and deaths; sensitivity and specificity of screening tools.

Results

For depression, 105 studies were included: 32 original studies (N=385 607) and 73 systematic reviews (including ≈2138 studies [N ≈ 9.8 million]). Depression screening interventions, many of which included additional components beyond screening, were associated with a lower prevalence of depression or clinically important depressive symptomatology after 6 to 12 months (pooled odds ratio, 0.60 [95% CI, 0.50-0.73]; reported in 8 randomized clinical trials [n=10 244]; I2 = 0%). Several instruments demonstrated adequate test accuracy (eg, for the 9-item Patient Health Questionnaire at a cutoff of 10 or greater, the pooled sensitivity was 0.85 [95% CI, 0.79-0.89] and specificity was 0.85 [95% CI, 0.82-0.88]; reported in 47 studies [n = 11 234]). A large body of evidence supported benefits of psychological and pharmacologic treatment of depression. A pooled estimate from trials used for US Food and Drug Administration approval suggested a very small increase in the absolute risk of a suicide attempt with second-generation antidepressants (odds ratio, 1.53 [95% CI, 1.09-2.15]; n = 40 857; 0.7% of antidepressant users had a suicide attempt vs 0.3% of placebo users; median follow-up, 8 weeks). Twenty-seven studies (n = 24 826) addressed suicide risk. One randomized clinical trial (n=443) of a suicide risk screening intervention found no difference in suicidal ideation after 2 weeks between primary care patients who were and were not screened for suicide risk. Three studies of suicide risk test accuracy were included; none included replication of any instrument. The included suicide prevention studies generally did not demonstrate an improvement over usual care, which typically included specialty mental health treatment.

Conclusions and Relevance

Evidence supported depression screening in primary care settings, including during pregnancy and postpartum. There are numerous important gaps in the evidence for suicide risk screening in primary care settings.

Internet-delivered psychological treatment as an add-on to treatment as usual for common mental disorders: A systematic review with meta-analysis of randomized trials

BACKGROUND

Psychological treatments for common mental disorders are increasingly being delivered remotely via the internet. Evidence suggests that internet-delivered cognitive behavioural therapy (iCBT) is superior to waitlist. However, the benefits are unclear of using this treatment modality as an add-on to treatment as usual (TAU) in regular healthcare.

METHODS

The literature was systematically searched up to August 2021 for randomized trials of internet-delivered psychological treatments using TAU as the comparator. Eligible participants were diagnosed with depressive, anxiety, obsessive-compulsive, or trauma- and stress-related disorders. Outcomes of interest were symptoms, functioning, quality of life, healthcare utilization, and negative effects. Results were synthesized using random-effects meta-analyses. Quality of evidence was assessed using GRADE.

RESULTS

The included studies evaluated iCBT for adults with depression (k = 9), depressive or anxiety disorders (k = 4), and post-traumatic stress disorder (k = 2) and were conducted in primary care or similar settings. For depression, low-certainty evidence suggested beneficial short-term effects on symptoms (g = -0.23; 95 % CI: = -0.37, -0.09), response rate (OR = 2.46; 1.31, 4.64), and remission (OR = 1.70; 1.19, 2.42;). The certainty of evidence was very low for long-term effects, other outcomes, and other disorders.

LIMITATIONS

TAU varied across studies and was often insufficiently described.

CONCLUSIONS

iCBT as a complement to usual care for adult with depression may result in a small incremental effect, which potentially could be clinically important. Studies are lacking for several common disorders and for children, adolescents, and the elderly. More robust studies of long-term effects are also needed, to better inform clinical decision-making.

Internet-delivered cognitive behavioral therapy (iCBT) for common mental disorders and subsequent sickness absence: a systematic review and meta-analysis

AIM

The study aimed to critically review and synthesize the best available evidence about the effectiveness of therapist-guided internet-delivered cognitive behavioral therapy (iCBT) in terms of reducing sickness absence (SA).

METHODS

We searched Medline (PubMed), Embase, PsycInfo, CINAHL, and Cochrane Central (up to November 2020) for English language peer-reviewed papers that described randomized controlled trials of therapist-guided iCBT compared with usual treatment for SA in adults with common mental disorders. Eligible studies were assessed with the Cochrane Risk of Bias 1 tool, meta-analysis was conducted using a random-effects model, and standardized mean differences (SMD) with 95% confidence intervals (CI) were reported. A subgroup analysis investigated potential moderating variables (diagnosis, SA at baseline, and estimated accuracy of self-report).

RESULTS

We identified 2788 references, of which 68 remained after the completion of the systematic screening process. A hand search of reference lists yielded no additional studies. The full texts of these 68 studies were appraised critically, and 11 were deemed to be suitable for a meta-analysis. SA was similar for iCBT and usual treatment groups (SMD: 0.02, 95% CI, -0.08 to 0.11), and remained similar even after the removal of two studies in which the recall time was over 3 months (SMD: 0.00, -0.11 to 0.12). Similar SA levels in intervention and control groups at 6-month and 12-month follow-up were observed in studies of participants with depression symptoms.

CONCLUSIONS

iCBT did not appear to be effective in terms of reducing (largely self-assessed) SA in adults with common mental disorders. There is a need to improve the method and consistency of assessing SA.

Efficacy of computer- and/or internet-based cognitive-behavioral guided self-management for depression in adults: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Depression is a worldwide disease. CBT-based self-help treatment allows patients with mild to moderate depression symptoms to improve their depression or to bridge the waiting- or pandemic period until they receive further clinical treatment.

OBJECTIVE

This systematic review and meta-analysis aims to explore the efficacy, acceptability and improvement in quality of life of computer-delivered and/or internet-based CBT self-help interventions with minimal guidance (up to 10 min) for depression. The second aim was to compare the effectiveness of reducing depression symptoms at post-treatment of treatment by the type of minimal guidance: (1) e-mail, (2) telephone calls, (3) e-mail and telephone together, or (4) face-to-face.

METHODS

The Cochrane depression, anxiety, and neurosis review group's specialized register electronic searches, grey literature, reference lists and correspondence were used to search for published and unpublished RCTs that reported efficacy of computer- and/or internet-based CBT self-help treatments for depression with minimal guidance up to 10 min per week. Methodological quality of included studies was evaluated with Cochrane Collaboration tools for assessing risk of bias. The meta-analysis was accomplished using the RevMen software.

RESULTS

In total, 2809 study abstracts were checked for eligibility. Out of these, 19 studies (21 samples) with a total of 3226 participants were included. The results showed that concerning efficacy, the treatment group is superior to the control group with a medium to large effect size of 0.65. Also, treatment groups with combined guidance by e-mail and telephone calls together had greater effects (SMD -0.76) than groups with other types of minimal guidance (guided by e-mail SMD -0.63; guided face to-face SMD - 0.66; guided by telephone calls SMD -0.49). Findings showed also, that iCBT with minimal guidance had small but statistically significant effect size of 0.28 in improving quality of life. Moreover, there were higher drop-out rates in the treatment condition (RR 1.36) than in the control groups.

CONCLUSIONS

The results of this meta-analysis support the efficacy of computer- and/or internet-based CBT self-help programs with minimal weekly guidance up to only 10 min for improving depression symptoms at post-treatment for adults. In addition, the results are pointing towards two practical implications. Firstly, depressed persons can use self-help treatment with minimal guidance at home to improve their symptoms or to bridge the waiting time - or pandemic period - before they receive professional face-to-face treatment. Secondly, it can help clinicians to make the decision about using CBT-based self-help treatments for patients that do not need urgent professional treatment, or to combine it with face-to-face therapy.

Motive-Oriented, Personalized, Internet-Based Interventions for Depression: Nonclinical Experimental Study

BACKGROUND

The low level of adherence in internet-based self-help interventions for depression suggests that in many existing programs, the motivational fit between the program and the user is unsatisfactory (eg, the user seeks autonomy, but the program provides directive guidance). Personalized, motive-oriented, self-help interventions could enable participants who interact with a program and its contents to have more engaging and less aversive experiences and thus increase adherence.

OBJECTIVE

In an experimental study with a nonclinical analogue sample, we aimed to test the hypotheses that a better motivational person-program fit is linked with higher anticipated adherence, working alliance, and satisfaction with the program.

METHODS

Motivational person-program fit was examined with respect to the 2 contrasting motives being autonomous and being supported. The hypotheses were tested by specifically varying the motivational person-program fit in a nonclinical sample (N=55), where participants were asked to work on, and subsequently evaluate, a limited set of individual pages of a self-help program with guidance (in the form of text messages) for depression. The sections of the self-help program were redesigned to either particularly address the autonomy motive or the support motive. For the quasi-experimental variation of the motivational person-program characteristics, we divided the 55 participants into 2 groups (autonomy group: n=27, 49%; support group: n=28, 51%) by screening method (using the Inventory of Approach and Avoidance Motivation), corresponding to the 2 motives. Both groups evaluated (in randomized order) 2 excerpts of the program-one that matched their motive (fit) and one that was contrary to it (no fit). Immediately after the evaluation of each excerpt, anticipated adherence, working alliance, and treatment satisfaction were assessed.

RESULTS

Regarding being supported, the satisfaction with or violation of this motive had an impact on (optimal) anticipated adherence as well as working alliance and satisfaction with the intervention; a congruent person-program fit resulted in significantly higher anticipated adherence (t27=3.00; P=.006), working alliance (t27=3.20; P=.003), and satisfaction (t27=2.86; P=.008) than a noncongruent fit. However, a similar impact could not be found for the motive being autonomous. Several correlations were found that supported our hypotheses (eg, for the congruent person-program fit autonomy motive and autonomy group, support satisfaction negatively correlated with optimal anticipated adherence).

CONCLUSIONS

This first experimental study gives reason to assume that motive orientation may have a positive influence on adherence, working alliance, and satisfaction in internet-based self-help interventions for depression and other mental disorders. Future studies should conduct randomized controlled trials with clinical samples and assess clinical outcomes.

Willingness to Use Internet-Based Versus Bibliotherapy Interventions in a Representative US Sample: Cross-sectional Survey Study

Background

Self-help interventions have the potential to increase access to evidence-based mental health care. Self-help can be delivered via different formats, including print media or digital mental health interventions (DMHIs). However, we do not know which delivery format is more likely to result in higher engagement.

Objective

The aims of this study were to identify if there is a preference for engaging in print media versus DMHIs and whether there are individual differences in relative preferences.

Methods

Participants were 423 adults between the ages of 18 and 82 years (201/423, 47.5% female) recruited on Prolific as a nationally representative sample of the US population, including non-Hispanic White (293/423, 69.2%), non-Hispanic Black (52/423, 12%), Asian (31/423, 7%), Hispanic (25/423, 6%), and other individuals (22/423, 5%). We provided individuals with psychoeducation in different self-help formats and measured their willingness to use print media versus DMHIs. We also assessed participants’ demographics, personality, and perception of each format’s availability and helpfulness and used these to predict individual differences in the relative preferences.

Results

Participants reported being more willing to engage with print media than with DMHIs (B=0.41, SE 0.08; t₄₂₂=4.91; P<.001; d=0.24, 95% CI 0.05-0.43). This preference appeared to be influenced by education level (B=0.22, SE 0.09; t₄₁₃=2.41; P=.02; d=0.13, 95% CI –0.06 to 0.32), perceived helpfulness (B=0.78, SE 0.06; t₄₁₁=13.66; P<.001; d=0.46, 95% CI 0.27-0.66), and perceived availability (B=0.20, SE 0.58; t₄₁₁=3.25; P=.001; d=0.12, 95% CI 0.07-0.30) of the self-help format.

Conclusions

This study suggests an overall preference for print media over DMHIs. Future work should investigate whether receiving mental health treatment via participants’ preferred delivery format can lead to higher engagement.

Understanding Mental Health Professionals' Perspectives and Practices Regarding the Implementation of Digital Mental Health: Qualitative Study

BACKGROUND

Despite the potential of digital mental health to provide cost-effective mental health care, its adoption in clinical settings is limited, and little is known about the perspectives and practices of mental health professionals regarding its implementation or the factors influencing these perspectives and practices.

OBJECTIVE

This study aims to characterize in depth the perspectives and practices of mental health professionals regarding the implementation of digital mental health and explore the factors affecting such perspectives and practices.

METHODS

A qualitative study using in-depth semistructured interviews with Portuguese mental health professionals (N=13)-psychologists and psychiatrists-was conducted. The transcribed interviews were thematically analyzed.

RESULTS

Mental health professionals deemed important or engaged in the following practices during the implementation of digital mental health: indication evaluation, therapeutic contract negotiation, digital psychological assessment, technology setup and management, and intervention delivery and follow-up. Low-threshold accessibility and professionals' perceived duty to provide support to their clients facilitated the implementation of digital mental health. Conversely, the lack of structured intervention frameworks; the unavailability of usable, validated, and affordable technology; and the absence of structured training programs inhibited digital mental health implementation by mental health professionals.

CONCLUSIONS

The publication of practice frameworks, development of evidence-based technology, and delivery of structured training seem key to expediting implementation and encouraging the sustained adoption of digital mental health by mental health professionals.

Mindfulness-based programmes for mental health promotion in adults in non-clinical settings: protocol of an individual participant data meta-analysis of randomised controlled trials

INTRODUCTION

With mental ill health listed as a top cause of global disease burden, there is an urgent need to prioritise mental health promotion programmes. Mindfulness-based programmes (MBPs) are being widely implemented to reduce stress in non-clinical settings. In a recent aggregate-level meta-analysis we found that, compared with no intervention, these MBPs reduce average psychological distress. However, heterogeneity between studies impedes generalisation of effects across every setting. Study-level effect modifiers were insufficient to reduce heterogeneity; studying individual-level effect modifiers is warranted. This requires individual participant data (IPD) and larger samples than those found in existing individual trials.

METHODS AND ANALYSIS

We propose an IPD meta-analysis. Our primary aim is to see if, and how, baseline psychological distress, gender, age, education and dispositional mindfulness moderate the effect of MBPs on distress. We will search 13 databases for good-quality randomised controlled trials comparing in-person, expert-defined MBPs in non-clinical settings with passive controls. Two researchers will independently select, extract and appraise trials using the revised Cochrane risk-of-bias tool. Anonymised IPD of eligible trials will be sought from authors, who will be invited to collaborate.The primary outcome will be psychological distress measured using psychometrically validated questionnaires at 1-6 months after programme completion. Pairwise random-effects two-stage IPD meta-analyses will be conducted. Moderator analyses will follow a 'deft' approach. We will estimate subgroup-specific intervention effects. Secondary outcomes and sensitivity analyses are prespecified. Multiple imputation strategies will be applied to missing data.

ETHICS AND DISSEMINATION

The findings will refine our knowledge on the effectiveness of MBPs and help improve the targeting of MBPs in non-clinical settings. They will be shared in accessible formats with a range of stakeholders. Public and professional stakeholders are being involved in the planning, conduct and dissemination of this project.

Rates and Predictors of Deterioration in a Trial of Internet-Delivered Cognitive Behavioral Therapy for Reducing Suicidal Thoughts

OBJECTIVE

It is necessary for suicide prevention interventions to demonstrate safety. One important aspect of safety is evidence that deterioration rates are low. No studies have examined deterioration of suicidal ideation in the context of an internet-based cognitive behavioral therapy (CBT) intervention to reduce suicidal ideation. A secondary analysis of the outcomes of an online trial was conducted to determine rates of deterioration in a CBT intervention called Living with Deadly Thoughts, relative to an attention control condition, and to identify factors associated with deterioration.

METHOD

The randomized controlled trial included 418 adults with suicidal ideation at baseline (77% females, mean age 40.6 years). Deterioration was defined in two ways: a reliable increase in Suicidal Ideation Attributes Scale (SIDAS score) of ≥6.0 units; or triggering the safety protocol during the trial as determined by high levels of suicidality. Analyses were repeated with multiply imputed data. Predictors of deterioration were identified using logistic regression analysis.

RESULTS

30 (14%) participants in the control group and 15 (7%) in the intervention group met criteria for reliable deterioration (Fisher's exact p = 0.027). In a fully adjusted logistic regression model, greater initial severity of suicidal thinking was associated with lower odds of deterioration, while intervention condition, demographics, psychological factors and mental health factors had no significant association with deterioration.

CONCLUSIONS

Participation in an online suicide prevention intervention was associated with lower prevalence of reliable deterioration than participation in an attention-control intervention, providing further evidence that internet-based CBT interventions do not cause harm.HighlightsFirst study to assess deterioration in an internet suicide prevention interventionRates of reliable deterioration were higher in control (14%) than intervention (7%)No psychological or demographic factors were robustly associated with deteriorationFindings provide further evidence that internet based CBT programs are not harmful.

Effects of an internet-based self-help intervention for psychological distress due to COVID-19: Results of a randomized controlled trial

BACKGROUND

The COVID-19 pandemic and its far-reaching impact on physical and mental health generate high demand and, accordingly, a great need for treatment opportunities that promote well-being and manage psychological distress. Internet-based interventions are particularly suitable for this purpose. They are easily scalable, readily accessible, and the online format allows for adherence to social distancing. For this reason, we developed an internet-based self-help intervention called ROCO to address psychological distress due to the COVID-19 pandemic. This randomized controlled trial aimed to examine the efficacy of the ROCO intervention.

METHODS

A total of 107 German-speaking adults with at least mild depressive symptoms were randomized either to the intervention group with direct access to the three-week ROCO intervention plus care as usual or the waiting control group receiving care as usual. Primary outcome (depressive symptoms) and secondary outcomes (stress, anxiety, resilience, emotion regulation, health-related quality of life, embitterment, loneliness, optimism, and self-efficacy) were assessed pre- and post-treatment and at a 6-week follow-up using self-report questionnaires (e.g. Patient Health Questionnaire-9 for depressive symptoms).

RESULTS

The average age was 40.36 years (SD = 14.59) and 81.3% of participants were female. The intervention did not significantly reduce primary depressive symptoms (between-group effect size: d = 0.04) and secondary outcomes such as anxiety and stress symptoms (between-group effect size: d = -0.19). However, the intervention led to a significant increase in emotion regulation skills (between-group effect size d = 0.35) and resilience (between-group effect size d = 0.38).

CONCLUSIONS

The internet-based self-help intervention cannot be recommended for the purpose of reducing depressive symptoms. However, the increase in emotion regulation skills and resilience suggest that the intervention may be suitable for preventive purposes, like improving overall coping with psychological distress or potential stressors. Future research is needed to examine for whom and how the intervention is most effective.

Internet-Delivered Versus Face-to-Face Cognitive Behavior Therapy for Anxiety Disorders: Systematic Review and Meta-Analysis

Background:

Over the last 20 years, internet-delivered cognitive behavior therapy (ICBT) has been tested in a large number of randomized controlled trials, often with positive results. However, it is not widely known about the efficacy of ICBT as compared to face-to-face cognitive behavior therapy (CBT).

Methods:

In the present systematic review and meta-analysis, ICBT for treatment of anxiety disorders was directly compared to face- to-face CBT within the same trial. This study aimed to reinvestigate the effect of ICBT compared to face-to-face CBT for anxiety disorders. A total of 8 studies out of the 236 articles screened met all the inclusion criteria. The included studies targeting five different anxiety disorders, social anxiety disorder, adolescent anxiety, panic disorder, spider phobia, and fear of public speaking, had been carried out in Australia, Spain, and Sweden. The total number of participants was 348 in ICBT and 316 in face-to-face conditions.

Results:

The results of our meta-analysis are interesting both from theoretical and practical standpoints, which showed a pooled effect size posttreatment with Hedges' g = 0.01 (95% CI: −0.16 to 0.18),

Conclusions:

ICBT and face-to-face CBT created equivalent overall effects. in treatment of anxiety disorders. Since there have been similar systematic reviews about anxiety disorders so far, and in majority of them, ICBT has not been compared against face-to-face treatment. More research is needed to establish the general equivalence of the two treatment formats. Also, understanding what makes ICBT work is a challenge for future research.

The Contribution of “Individual Participant Data” Meta-Analyses of Psychotherapies for Depression to the Development of Personalized Treatments: A Systematic Review

While randomized trials typically lack sufficient statistical power to identify predictors and moderators of outcome, ”individual participant data” (IPD) meta-analyses, which combine primary data of multiple randomized trials, can increase the statistical power to identify predictors and moderators of outcome. We conducted a systematic review of IPD meta-analyses on psychological treatments of depression to provide an overview of predictors and moderators identified. We included 10 (eight pairwise and two network) IPD meta-analyses. Six meta-analyses showed that higher baseline depression severity was associated with better outcomes, and two found that older age was associated with better outcomes. Because power was high in most IPD meta-analyses, non-significant findings are also of interest because they indicate that these variables are probably not relevant as predictors and moderators. We did not find in any IPD meta-analysis that gender, education level, or relationship status were significant predictors or moderators. This review shows that IPD meta-analyses on psychological treatments can identify predictors and moderators of treatment effects and thereby contribute considerably to the development of personalized treatments of depression.

Back2Action: effectiveness of physiotherapy blended with eHealth consisting of pain education and behavioural activation versus physiotherapy alone-protocol for a pragmatic randomised clinical trial for people with subacute or persistent spinal pain

INTRODUCTION

Psychosocial factors predict recovery in patients with spinal pain. Several of these factors are modifiable, such as depression and anxiety. However, primary care physiotherapists who typically manage these patients indicate that they do not feel sufficiently competent and equipped to address these factors optimally. We developed an eHealth intervention with a focus on pain education and behavioural activation to support physiotherapists in managing psychosocial factors in patients with spinal pain. This paper describes the protocol for a pragmatic randomised clinical trial, which evaluates the effectiveness of this eHealth intervention blended with physiotherapy compared with physiotherapy alone.

METHODS AND ANALYSIS

Participants with non-specific low back pain and/or neck pain for at least 6 weeks who also have psychosocial risk factors associated with the development or maintenance of persistent pain will be recruited in a pragmatic multicentre cluster randomised clinical trial. The experimental intervention consists of physiotherapy blended with six online modules of pain education and behavioural activation. The control intervention consists of usual care physiotherapy. The primary outcomes are disability (Oswestry Disability Index for low back pain and Neck Disability Index for neck pain) and perceived effect (Global Perceived Effect). Outcomes will be assessed at baseline and at 2, 6 and 12 months after baseline. The results will be analysed using linear mixed models.

ETHICS AND DISSEMINATION

The study is approved by the Medical Ethical Committee of VU Medical Center Amsterdam, The Netherlands (2017.286). Results will be reported in peer-reviewed journals, at national and international conferences, and in diverse media to share the findings with patients, clinicians and the public.

Effectiveness and Moderators of an Internet-Based Mobile-Supported Stress Management Intervention as a Universal Prevention Approach: Randomized Controlled Trial

Background

Emerging evidence indicates the effectiveness of internet-based mobile-supported stress management interventions (iSMIs) in highly stressed employees. It is yet unclear, however, whether iSMIs are also effective without a preselection process in a universal prevention approach, which more closely resembles routine occupational health care. Moreover, evidence for whom iSMIs might be suitable and for whom not is scarce.

Objective

The aim of this study was to evaluate the iSMI GET.ON Stress in a universal prevention approach without baseline inclusion criteria and to examine the moderators of the intervention effects.

Methods

A total of 396 employees were randomly assigned to the intervention group or the 6-month waiting list control group. The iSMI consisted of 7 sessions and 1 booster session and offered no therapeutic guidance. Self-report data were assessed at baseline, 7 weeks, and at 6 months following randomization. The primary outcome was perceived stress. Several a priori defined moderators were explored as potential effect modifiers.

Results

Participants in the intervention group reported significantly lower perceived stress at posttreatment (d=0.71, 95% CI 0.51-0.91) and at 6-month follow-up (d=0.61, 95% CI 0.41-0.81) compared to those in the waiting list control group. Significant differences with medium-to-large effect sizes were found for all mental health and most work-related outcomes. Resilience (at 7 weeks, P=.04; at 6 months, P=.01), agreeableness (at 7 weeks, P=.01), psychological strain (at 6 months, P=.04), and self-regulation (at 6 months, P=.04) moderated the intervention effects.

Conclusions

This study indicates that iSMIs can be effective in a broad range of employees with no need for preselection to achieve substantial effects. The subgroups that might not profit had extreme values on the respective measures and represented only a very small proportion of the investigated sample, thereby indicating the broad applicability of GET.ON Stress.

Insight and the number of completed modules predict a reduction of positive symptoms in an Internet-based intervention for people with psychosis

Emerging evidence suggests that Internet-based interventions for people with psychosis (ICBTp) are feasible and efficacious. However, predictors of adherence and treatment outcomes are largely unknown. To narrow this research gap, we conducted secondary analyses on data from a randomized controlled trial, which evaluated an eight-week ICBTp intervention targeting topics, such as voice hearing, mindfulness, and others. In n = 100 participants with psychosis, we aimed at identifying sociodemographic, psychopathological, and treatment-related predictor variables of post-treatment symptoms and adherence (i.e., at least four completed modules). We followed a two-stage approach. First, we conducted regression analyses to examine the effect of single candidate predictors on post-treatment symptoms as well as adherence. Subsequently, we selected variables that met a significance threshold of p < .1 and entered them into linear and logistic multiple regression models. Whereas no variable was able to predict adherence, the number of completed modules was negatively associated with self-reported delusion severity at post-treatment. Additionally, higher pre-treatment insight predicted fewer hallucinations after treatment. Because this was one of the first studies to investigate predictors in ICBTp, more research is needed to customize future interventions to the needs of users.

How are guide profession and routine care setting related to adherence and symptom change in iCBT for depression? - an explorative log-data analysis

BACKGROUND

While the antidepressant efficacy of guided digital interventions has been proven in randomized controlled trials, findings from routine care are less clear. Low adherence rates are common and limit the potential effectiveness. Adherence has been linked to sociodemographic variables and the amount of guidance, but the role of the guide's profession and their work setting has not yet been studied for routine care.

METHODS

Routinely collected log data from a digital intervention for depressed patients (iFightDepression tool) were analyzed in an exploratory manner. The sample is a convenience sample from routine care, where guidance is provided by general practitioners (GP), certified psychotherapists (PT) or medical doctors specialized in mental health. Log data from 2184 patients were analyzed and five usage parameters were extracted to measure adherence (first-to-last login, time on tool, number of sessions, workshops completed and minimal dose). Multiple logistic regression was used to analyze relations between the guide's profession and clinical context as well as other covariates and adherence and symptom change on a brief depression questionnaire (PHQ-9).

RESULTS

The analyses showed a significant relation of guide profession and adherence. Guidance by PT was associated to the highest adherence scores (reference category). The odds ratios (ORs) of scoring above the median in each usage parameter for patients guided by GPs were 0.50-0.63 (all ps < 0.002) and 0.61-0.80 (p = .002-0.197) for MH. Higher age, initial PHQ-9 score and self-reported diagnosis of depression were also significantly associated with higher adherence scores. In a subsample providing enough data on the PHQ-9 (n = 347), no association of guide profession with symptom reduction was found. Instead, a greater reduction was observed for patients with a higher baseline PHQ-9 (β = -0. 39, t(341.75) = -8.814, p < .001) and for those who had achieved minimal dose (β = -2.42, t(340.34) = -4.174, P < .001) and those who had achieved minimal dose and scored high on time on tool (β = 0.22, t(341.75) = 1.965, P = .050).

CONCLUSION

Being guided by PT was associated with the highest adherence. The lowest adherence was observed in patients who were guided by GP. While no association of guide profession and symptom reduction was found in a subsample, greater adherence was associated with symptom reduction.

Effectiveness of a Guided Web-Based Intervention to Reduce Depressive Symptoms before Outpatient Psychotherapy: A Pragmatic Randomized Controlled Trial

INTRODUCTION

Psychotherapy is a first-line treatment for depression. However, capacities are limited, leading to long waiting times for outpatient psychotherapy in health care systems. Web-based interventions (WBI) could help to bridge this treatment gap.

OBJECTIVE

This study investigates the effectiveness of a guided cognitive-behavioral WBI in depressive patients seeking face-to-face psychotherapy.

METHODS

A 2-arm randomized controlled trial was conducted. Depressive patients (n = 136) recruited from the waiting lists of outpatient clinics were randomly assigned to an intervention group (IG; treatment as usual [TAU] + immediate access to WBI) or a control group (CG; TAU + access to WBI after follow-up). Depressive symptoms and secondary outcomes were assessed at baseline, 7 weeks, and 5 months after randomization.

RESULTS

Mixed-model analyses revealed a significant group × time interaction effect on depressive symptoms (F2, 121.5 = 3.91; p < 0.05). Between-group effect sizes were d = 0.55 at 7 weeks and d = 0.52 at 5 months. The IG was superior regarding psychological symptoms and mental health quality of life but not on physical health quality of life, attitudes, motivation for psychotherapy, or subjective need and uptake of psychotherapy.

CONCLUSIONS

Patients waiting for face-to-face psychotherapy can benefit from a WBI when compared to TAU. Despite the reduction of depressive symptoms in the IG, the uptake of subsequent psychotherapy was still high in both groups. The effects remained stable at the 5-month follow-up. However, this study could not determine the proportion of specific intervention effects vs. nonspecific effects, such as positive outcome expectations or attention. Future research should focus on the long-term effects and cost-effectiveness of WBI before psychotherapy.

Efficacy and Moderators of Internet-Based Interventions in Adults with Subthreshold Depression: An Individual Participant Data Meta-Analysis of Randomized Controlled Trials

INTRODUCTION

Evidence on effects of Internet-based interventions to treat subthreshold depression (sD) and prevent the onset of major depression (MDD) is inconsistent.

OBJECTIVE

We conducted an individual participant data meta-analysis to determine differences between intervention and control groups (IG, CG) in depressive symptom severity (DSS), treatment response, close to symptom-free status, symptom deterioration and MDD onset as well as moderators of intervention outcomes.

METHODS

Randomized controlled trials were identified through systematic searches via PubMed, PsycINFO, Embase and Cochrane Library. Multilevel regression analyses were used to examine efficacy and moderators.

RESULTS

Seven trials (2,186 participants) were included. The IG was superior in DSS at all measurement points (posttreatment: 6-12 weeks; Hedges' g = 0.39 [95% CI: 0.25-0.53]; follow-up 1: 3-6 months; g = 0.30 [95% CI: 0.15-0.45]; follow-up 2: 12 months, g = 0.27 [95% CI: 0.07-0.47], compared with the CG. Significantly more participants in the IG than in the CG reached response and close to symptom-free status at all measurement points. A significant difference in symptom deterioration between the groups was found at the posttreatment assessment and follow-up 2. Incidence rates for MDD onset within 12 months were lower in the IG (19%) than in the CG (26%). Higher initial DSS and older age were identified as moderators of intervention effect on DSS.

CONCLUSIONS

Our findings provide evidence for Internet-based interventions to be a suitable low-threshold intervention to treat individuals with sD and to reduce the incidence of MDD. This might be particularly true for older people with a substantial symptom burden.

Negative effects in internet-based interventions for depression: A qualitative content analysis

An increasing number of studies is proving the efficacy of Internet-based interventions (IBI) for treating depression. While the focus of most studies is thereby lying on the potential of IBI to alleviate emotional distress and enhance well-being, few studies are investigating possible negative effects that might be encountered by participants. The current study was therefore exploring self-reported negative effects of participants undergoing a cognitive-behavioral IBI targeting mild to moderate depression over 6 weeks. Data from the client pool of a German insurance company (n = 814, 68% female) revealed that 8.6% of the participants reported the experience of negative effects. Qualitative content analysis yielded two broad categories and five subcategories for the nature of participants' experiences of negative effects: participant-related negative effects (insight and symptom) and program-related negative effects (online format, contact, and implementation). By using both, qualitative and quantitative methods, results did not only shed light on the characteristics of negative effects but analyses also found that working alliance was a predictor for the experience of negative effects. Monitoring the occurrences of negative effects as well as working alliance throughout treatment was considered essential to help prevent negative effects and attrition among participants undergoing IBI for depression.

Banbury Forum Consensus Statement on the Path Forward for Digital Mental Health Treatment

A major obstacle to mental health treatment for many Americans is accessibility: the United States faces a shortage of mental health providers, resulting in federally designated shortage areas. Although digital mental health treatments (DMHTs) are effective interventions for common mental disorders, they have not been widely adopted by the U.S. health care system. National and international expert stakeholders representing health care organizations, insurance companies and payers, employers, patients, researchers, policy makers, health economists, and DMHT companies and the investment community attended two Banbury Forum meetings. The Banbury Forum reviewed the evidence for DMHTs, identified the challenges to successful and sustainable implementation, investigated the factors that contributed to more successful implementation internationally, and developed the following recommendations: guided DMHTs should be offered to all patients experiencing common mental disorders, DMHT products and services should be reimbursable to support integration into the U.S. health care landscape, and an evidence standards framework should be developed to support decision makers in evaluating DMHTs.

Results of the Optimune trial: A randomized controlled trial evaluating a novel Internet intervention for breast cancer survivors

INTRODUCTION

After the acute treatment phase, breast cancer patients often experience low quality of life and impaired mental health, which could potentially be improved by offering cognitive behavioural therapy (CBT) and addressing exercise and dietary habits. However, CBT and other behavioural interventions are rarely available beyond the acute treatment phase. Internet-based interventions could bridge such treatment gaps, given their flexibility and scalability. In this randomized controlled trial (RCT), we investigated the effects of such an intervention ("Optimune") over three months.

METHODS

This RCT included 363 female breast cancer survivors (age range = 30-70), recruited from the community, who had completed the active treatment phase. Inclusion criteria were: breast cancer diagnosis less than 5 years ago and acute treatment completion at least 1 month ago. Participants were randomly assigned to (1) an intervention group (n = 181), in which they received care as usual (CAU) plus 12-month access to Optimune immediately after randomization, or (2) a control group (n = 182), in which they received CAU and Optimune after a delay of 3 months. Primary endpoints were quality of life (QoL), physical activity, and dietary habits at three months. We hypothesized that intervention group participants would report better QoL, more physical activity, and improved dietary habits after 3 months.

RESULTS

Intention-to-treat (ITT) analyses revealed significant effects on QoL (d = 0.27, 95% CI: 0.07-0.48) and dietary habits (d = 0.36, 95% CI: 0.15-0.56), but the effect on physical exercise was not significant (d = 0.30; 95% CI: 0.10-0.51).

DISCUSSION

These findings suggest the effectiveness of Optimune, a new CBT-based Internet intervention for breast cancer survivors, in facilitating improvements in quality of life and dietary habits. Efforts to disseminate this intervention more broadly may be warranted.

E-mental health applications for depression: an evidence-based ethical analysis

E-mental health applications (apps) are an increasingly important factor for the treatment of depression. To assess the risks and benefits for patients, an in-depth ethical analysis is necessary. The objective of this paper is to determine the ethical implications of app-based treatment for depression. An evidence-based ethical analysis was conducted. The material was meta-reviews and randomized control studies (RCTs) on app-based treatment. Based on the empirical data, an ethical analysis was conducted using the 3-ACES-approach by Thornicroft and Tansella. Apps may empower autonomy, offer an uninterrupted series of contacts over a period of time, show evidence-based benefits for patients with subclinical and mild-to-moderate-symptoms, are easily accessible, may be used for coordinating information and services within an episode of care, and are on the whole cost-effective. Their risks are that they are not suitable for the whole range of severity of mental illnesses and patient characteristics, show severe deficits in the data privacy policy, and a big variability in quality standards. The use of apps in depression treatment can be beneficial for patients as long as (1) the usefulness of an app-based treatment is assessed for each individual patient, (2) apps are chosen according to symptom severity as well as characteristics like the patient's level of self-reliance, their e-literacy, and their openness vis-à-vis apps, (3) manufacturers improve their privacy policies and the quality of apps.

Evidence on Technology-Based Psychological Interventions in Diagnosed Depression: Systematic Review

BACKGROUND

Evidence on technology-based psychological interventions (TBIs) for the treatment of depression is rapidly growing and covers a broad scope of research. Despite extensive research in this field, guideline recommendations are still limited to the general effectiveness of TBIs.

OBJECTIVE

This study aims to structure evidence on TBIs by considering different application areas (eg, TBIs for acute treatment and their implementation in health care, such as stand-alone interventions) and treatment characteristics (eg, therapeutic rationale of TBIs) to provide a comprehensive evidence base and to identify research gaps in TBIs for diagnosed depression. Moreover, the reporting of negative events in the included studies is investigated in this review to enable subsequent safety assessment of the TBIs.

METHODS

Randomized controlled trials on adults diagnosed with unipolar depression receiving any kind of psychotherapeutic treatment, which was at least partly delivered by a technical medium, were eligible for inclusion in our preregistered systematic review. We searched for trials in CENTRAL (Cochrane Central Register of Controlled Trials; until August 2020), MEDLINE, PsycINFO, PSYNDEX, CINAHL; until the end of January 2018), clinical trial registers, and sources of gray literature (until the end of January 2019). Study selection and data extraction were conducted by 2 review authors independently.

RESULTS

Database searches resulted in 15,546 records, of which 241 publications were included, representing 83 completed studies and 60 studies awaiting classification (ie, preregistered studies, study protocols). Almost all completed studies (78/83, 94%) addressed the acute treatment phase, being largely either implemented as stand-alone interventions (66/83, 80%) or blended treatment approaches (12/83, 14%). Studies on TBIs for aftercare (4/83, 5%) and for bridging waiting periods (1/83, 1%) were scarce. Most TBI study arms (n=107) were guided (59/107, 55.1%), delivered via the internet (80/107, 74.8%), and based on cognitive behavioral treatment approaches (88/107, 79.4%). Almost all studies (77/83, 93%) reported information on negative events, considering dropouts from treatment as a negative event. However, reports on negative events were heterogeneous and largely unsystematic.

CONCLUSIONS

Research has given little attention to studies evaluating TBIs for aftercare and for bridging waiting periods in people with depression, even though TBIs are seen as highly promising in these application areas; thus, high quality studies are urgently needed. In addition, the variety of therapeutic rationales on TBIs has barely been represented by identified studies hindering the consideration of patient preferences when planning treatment. Finally, future studies should use specific guidelines to systematically assess and report negative events.

Mediators and mechanisms of change in internet- and mobile-based interventions for depression: A systematic review

The efficacy of Internet- and mobile-based interventions (IMIs) for depression in adults is well established. Yet, comprehensive knowledge on the mediators responsible for therapeutic change in these interventions is pending. Therefore, we conducted the first systematic review on mediators in IMIs for depression, investigating mechanisms of change in interventions with different theoretical backgrounds and delivery modes (PROSPERO CRD42019130301). Two independent reviewers screened references from five databases (i.e., Cochrane Library, Embase, MEDLINE/PubMed, PsycINFO and ICTRP), selected studies for inclusion and extracted data from eligible studies. We included 26 RCTs on mediators in IMIs for depression (6820 participants), rated their risk of bias and adherence to methodological quality criteria for psychotherapy process research. Primary studies examined 64 mediators, with cognitive variables (e.g., perceived control, rumination or interpretation bias) being the largest group of both examined (m = 28) and significant mediators (m = 22); followed by a range of other mediators, including mindfulness, acceptance and behavioral activation. Our findings might contribute to the empirically-informed advancement of interventions and mental health care practices, enabling optimized treatment outcomes for patients with depression. Furthermore, we discuss implications for future research and provide methodological recommendations for forthcoming mediation studies with more pertinent designs, allowing for inferences with higher causal specificity.

Are Internet- and mobile-based interventions effective in adults with diagnosed panic disorder and/or agoraphobia? A systematic review and meta-analysis

BACKGROUND

There is no meta-analysis that specifically evaluates the effectiveness of Internet- and mobile-based interventions (IMIs) in adults with diagnosed panic disorder and/or agoraphobia (PD/A) so far. The current meta-analysis aims to fill this gap (PROSPERO CRD 42016034016).

METHODS

Systematic literature searches in six databases for randomised and controlled clinical trials investigating IMIs in adults, who met diagnostic criteria for PD/A. Study selection and data extraction were conducted independently by two reviewers. Random-effects meta-analyses, pre-planned subgroup and sensitivity analyses were conducted when appropriate. Primary outcomes were PD and A symptom severity. In addition, adherence, response, remission, quality of life, anxiety and depression symptom severity were examined.

RESULTS

A total of 16 trials (1015 patients), with 21 comparisons (9 IMI vs. waitlist; 7 IMI vs. IMI; 5 IMI vs. active treatment condition), were included. IMIs revealed beneficial effects on panic (Hedges' g range -2.61 to -0.25) and agoraphobia symptom severity when compared to waitlist (pooled g = -1.15, [95%-CI = -1.56; -0.74]). Studies comparing IMIs to active controls (i.e., face-to-face CBT and applied relaxation) did not find significant differences for reductions in panic (g = -0.02, [95%-CI = -0.25; 0.21]) and agoraphobia symptom severity (g = -0.10, [95%-CI = -0.39; 0.19]). Furthermore, IMIs were superior to waitlist controls regarding anxiety and depression symptom severity and quality of life.

LIMITATIONS

Tests for publication bias were not feasible due to the limited number of trials per comparison, and the risk of bias assessment indicated some methodological shortcomings.

CONCLUSIONS

Findings from this meta-analytic review provide support for the effectiveness of IMIs in patients with verified PD/A. However, before IMIs can be included in treatment guidelines for PD/A, future high quality research is needed that substantiates and extends the evidence base, especially in regard to intervention safety.

A randomised trial comparing a brief online delivery of mindfulness-plus-values versus values only for symptoms of depression: Does baseline severity matter?

BACKGROUND

Acceptance/mindfulness-based interventions often focus on (a) developing dispositional mindfulness and (b) pursuing personally meaningful and valued activities. Acceptance/mindfulness-based interventions can reduce depression, but little is known about the combined effects of components or the influence of baseline variables on outcomes. This study tested whether practicing a brief (10-min) mindfulness meditation over a 2-week period followed by a single values session (mindfulness+values) was more effective than values alone (values only) in reducing symptoms of depression. The study was delivered online and modules were fully self-help (i.e., no therapist contact).

METHODS

206 participants (M_age=23.4 years, SD=6.53) with elevated depression scores (DASS-depression ≥ 10) were randomised to: mindfulness+values condition or a 2-week wait period followed by the values session (i.e., values only condition). Symptoms of depression were assessed at baseline, after the 2-week mindfulness practice/wait period, and 1-week following the values session.

RESULTS

Reductions in depression and recovery rates were significantly greater following mindfulness+values than values only. Baseline severity affected outcomes: mindfulness+values was significantly more beneficial than values only for individuals with high baseline levels of depression. Outcomes did not differ for those with low levels of depression. Rates of deterioration were higher than expected for values only participants.

LIMITATIONS

Conclusions are preliminary and tentative due to no follow-up period and a small sample. Drop-out was high (50%) and findings cannot be assumed to generalise to treatment seeking or more diverse samples.

CONCLUSIONS

Tentatively, results suggest mindfulness+values can significantly reduce depression, especially for individuals with higher baseline depression.
