The impact of school-based creative bibliotherapy interventions on child and adolescent mental health: a systematic review and realist synthesis protocol

BACKGROUND

There is a need to identify evidence-based interventions to be delivered in schools that can be used to improve child and adolescent mental health and wellbeing. Creative bibliotherapy is one proposed intervention. However, there has been, to date, no comprehensive assessment of the evidence for its impact on mental health and wellbeing. To fill this gap, we will conduct a systematic review and realist synthesis.

METHODS

A systematic search of the bibliographic databases APA PsycINFO, Medline (via Ovid), CINAHL, ERIC, Education Research Complete (via EBSCOhost) and Web of Science (SCI, SSCI, AHCI, ESCI) for school-based creative bibliotherapy interventions on child and adolescent mental health. Types of study to be included: cohort studies, non-randomised comparative evaluations, randomised controlled trials. The data from all included studies will be summarised descriptively and strength of evidence appraised. This is a potentially large field of practice, with heterogeneous interventions; we will use methods from intervention components analysis to describe and categorise the range of components and approaches used in included interventions. To understand how interventions work and in which contexts, we will use methods from realist synthesis to develop an exploratory account of mechanisms in different settings and for different young people (contexts).

DISCUSSION

Findings will assess the range of evidence for the impact of creative bibliotherapy on child and adolescent mental health and wellbeing, the strength of evidence for the impact identified, and describe potential mechanisms. This review will be useful for a wide range of stakeholders considering implementing or developing interventions using creative bibliotherapy in school-based settings.

A comparison of the effectiveness of cognitive behavioural interventions based on delivery features for elevated symptoms of depression in adolescents: A systematic review

Background

Depression is a public health problem and common amongst adolescents. Cognitive behavioural therapy (CBT) is widely used to treat adolescent depression but existing research does not provide clear conclusions regarding the relative effectiveness of different delivery modalities.

Objectives

The primary aim is to estimate the relative efficacy of different modes of CBT delivery compared with each other and control conditions for reducing depressive symptoms in adolescents. The secondary aim is to compare the different modes of delivery with regard to intervention completion/attrition (a proxy for intervention acceptability).

Search Methods

The Cochrane Depression, Anxiety and Neurosis Clinical Trials Register was searched in April 2020. MEDLINE, PsycInfo, EMBASE, four other electronic databases, the CENTRAL trial registry, Google Scholar and Google were searched in November 2020, together with reference checking, citation searching and hand-searching of two databases.

Selection Criteria

Randomised controlled trials (RCTs) of CBT interventions (irrespective of delivery mode) to reduce symptoms of depression in young people aged 10-19 years with clinically relevant symptoms or diagnosis of depression were included.

Data Collection and Analysis

Screening and data extraction were completed by two authors independently, with discrepancies addressed by a third author. CBT interventions were categorised as follows: group CBT, individual CBT, remote CBT, guided self-help, and unguided self-help. Effect on depressive symptom score was estimated across validated self-report measures using Hedges' g standardised mean difference. Acceptability was estimated based on loss to follow-up as an odds ratio. Treatment rankings were developed using the surface under the cumulative ranking curve (SUCRA). Pairwise meta-analyses were conducted using random effects models where there were two or more head-to-head trials. Network analyses were conducted using random effects models.

Main Results

Sixty-eight studies were included in the review. The mean age of participants ranged from 10 to 19.5 years, and on average 60% of participants were female. The majority of studies were conducted in schools (28) or universities (6); other settings included primary care, clinical settings and the home. The number of CBT sessions ranged from 1 to 16, the frequency of delivery from once every 2 weeks to twice a week and the duration of each session from 20 min to 2 h. The risk of bias was low across all domains for 23 studies, 24 studies had some concerns and the remaining 21 were assessed to be at high risk of bias. Sixty-two RCTs (representing 6435 participants) were included in the pairwise and network meta-analyses for post-intervention depressive symptom score at post-intervention. All pre-specified treatment and control categories were represented by at least one RCT. Although most CBT approaches, except remote CBT, demonstrated superiority over no intervention, no approaches performed clearly better than or equivalent to another. The highest and lowest ranking interventions were guided self-help (SUCRA 83%) and unguided self-help (SUCRA 51%), respectively (very low certainty in treatment ranking). Nineteen RCTs (3260 participants) were included in the pairwise and network meta-analyses for 6 to 12 month follow-up depressive symptom score. Neither guided self-help nor remote CBT were evaluated in the RCTs for this time point. Effects were generally attenuated for 6- to 12-month outcomes compared to posttest. No interventions demonstrated superiority to no intervention, although unguided self-help and group CBT both demonstrated superiority compared to TAU. No CBT approach demonstrated clear superiority over another. The highest and lowest ranking approaches were unguided self-help and individual CBT, respectively. Sixty-two RCTs (7347 participants) were included in the pairwise and network meta-analyses for intervention acceptability. All pre-specified treatment and control categories were represented by at least one RCT. Although point estimates tended to favour no intervention, no active treatments were clearly inferior. No CBT approach demonstrated clear superiority over another. The highest and lowest ranking active interventions were individual CBT and group CBT respectively. Pairwise meta-analytic findings were similar to those of the network meta-analysis for all analyses. There may be age-based subgroup effects on post-intervention depressive symptoms. Using the no intervention control group as the reference, the magnitudes of effects appear to be larger for the oldest age categories compared to the other subgroups for each given comparison. However, they were generally less precise and formal testing only indicated a significant difference for group CBT. Findings were robust to pre-specified sensitivity analyses separating out the type of placebo and excluding cluster-RCTs, as well as an additional analysis excluding studies where we had imputed standard deviations.

Authors' Conclusions

At posttreatment, all active treatments (group CBT, individual CBT, guided self-help, and unguided self-help) except for remote CBT were more effective than no treatment. Guided self-help was the most highly ranked intervention but only evaluated in trials with the oldest adolescents (16-19 years). Moreover, the studies of guided self-help vary in the type and amount of therapist support provided and longer-term results are needed to determine whether effects persist. The magnitude of effects was generally attenuated for 6- to 12-month outcomes. Although unguided self-help was the lowest-ranked active intervention at post-intervention, it was the highest ranked at follow-up. This suggests the need for further research into whether interventions with self-directed elements enable young people to maintain effects by continuing or revisiting the intervention independently, and whether therapist support would improve long-term outcomes. There was no clear evidence that any active treatments were more acceptable to participants than any others. The relative effectiveness of intervention delivery modes must be taken into account in the context of the needs and preferences of individual young people, particularly as the differences between effect sizes were relatively small. Further research into the type and amount of therapist support that is most acceptable to young people and most cost-effective would be particularly useful.

Efficacy of low intensity interventions for geriatric depression and anxiety - A systematic review and meta-analysis

BACKGROUND

This systematic review and meta-analysis examined the efficacy of low intensity psychological interventions for older adults (60+ years) with clinical anxiety and/or depressive disorders.

METHOD

Systematic review and meta-analysis of randomised control trials of low-intensity psychological interventions for anxiety and/or depression with an active or passive control condition (e.g., waitlist, treatment-as-usual or active control) in any setting. Low intensity psychological interventions (e.g., cognitive behaviour therapy [CBT]) targeted anxiety and/or depression as primary outcomes, were primarily self-help, and included support from trained practitioners/facilitators with <6 h total contact time (typically <30 min p/contact).

RESULTS

Seven studies consisting of 304 older adults (65-78 years, Mage = 70, SD = 4) were identified and six included in the meta-analysis of depression outcomes and three for anxiety. A random effects meta-analysis of group differences in symptom change from pre-post treatment found evidence favouring low intensity psychological interventions over passive control groups for the treatment of depressive and anxiety symptoms, with moderate effect sizes for depression (Cohen's d = -0.62) and large effect sizes for anxiety (Cohen's d = -0.84) at post-treatment.

LIMITATIONS

Results are limited by study design of included studies such that the efficacy of interventions compared to treatment-as-usual, non-CBT approaches, in adults >80 years and long-term effects are unknown.

CONCLUSIONS

There is some evidence supporting the clinical benefits of low intensity psychological interventions for depressive and anxiety symptoms in older adults compared to passive controls. More research is needed to examine efficacy compared to active control conditions, and among those over 80 years.

Nonpharmacological interventions for subthreshold depression in adults: A systematic review and network meta-analysis

Subthreshold depression (StD) is very common, with an estimated global incidence of 25%, and is associated with other clinical conditions. Nonpharmacological interventions have been demonstrated to be effective, but which one is best should be further investigated. This study aims to compare and rank the efficacy of nonpharmacological interventions in adults with StD. Ten databases were searched, and comparisons were made using a random-effects network meta-analysis using the frequentist framework. The assumption of local consistency was assessed by using the node-splitting method. The surface under the cumulative ranking curve (SUCRA) was used to separately rank each intervention. A total of 32 randomized controlled trials (RCTs) were included. The results showed that psychotherapy, as an intervention class, had significantly positive effects compared to control groups (SMD = -0.78, 95% CI: -1.06, -0.49) and had the highest rank (SUCRA, 79.0%; mean rank, 1.6). Cognitive behavioral therapy (CBT), as an individual intervention, had significantly positive effects relative to all control groups and had the highest rank (SUCRA, 82.5%; mean rank, 3.1). We speculate that psychotherapy, especially CBT, may be the most effective nonpharmacological intervention to improve StD in adults. More RCTs examining the efficacy of different nonpharmacological interventions are needed.

Efficacy of psychological interventions for young adults with mild-to-moderate depressive symptoms: A meta-analysis

BACKGROUND

Psychological interventions are commonly used to treat mild-to-moderate depression, but their efficacy in young adults has not been exhaustively addressed. This meta-analysis aims to establish it in comparison to no treatment, wait-list, usual treatment, passive interventions, and other bona-fide treatments.

METHODS

The search was conducted in Scopus, MEDLINE, PsycINFO, ClinicalTrials.gov, the ISRCTN Registry, Cochrane CENTRAL, Clarivate BIOSIS Previews and the METAPSY database, retrieving studies from the start of records to April 2020. Eligibility criteria included samples of 16-30 years experiencing mild-to-moderate depressive symptoms and participating in randomized controlled trials (RCTs), non-RCTs, or pre-post studies measuring depressive symptomatology and featuring psychological treatments.

RESULTS

Up to 45 studies met criteria, consisting of 3,947 participants, assessed using the Quality Assessment Tool for Quantitative Studies and their results meta-analyzed assuming random effects. Psychological interventions proved to be efficacious in RCTs compared to no treatment (g = -0.68; 95% CI = -0.87, -0.48) and wait-list (g = -1.04; 95% CI = -1.25, -0.82), while depressive symptoms also improved in pre-post studies (g = -0.99; 95% CI = -1.32, -0.66). However, intervention efficacy was similar to usual care, passive, and bona-fide comparators. The heterogeneity found, a likely reporting bias and the low quality of most studies must be considered when interpreting these results.

CONCLUSIONS

Psychological treatments are efficacious to reduce depressive symptoms in young adults, but comparable to other interventions in the mild-to-moderate range. Moderators like depression severity or therapist involvement significantly influenced their efficacy, with results encouraging clinicians to adopt flexible and personalized approaches.

Influence of placebo effect in mental disorders research: A systematic review and meta-analysis

BACKGROUND

Randomized controlled trials (RCT) in mental disorders research commonly use active control groups including psychotherapeutic shams or inactive medication. This meta-analysis assessed whether placebo conditions (active controls) had an effect compared to no treatment or usual care (passive controls).

METHODS

PubMed, Scopus, PsycINFO, PsycARTICLES, Ovid, the Cochrane Central Register of Controlled Trials and Web of Science were searched from inception to April 2021 and reference lists of relevant articles. Three-arm RCTs, including active and passive control groups, were selected. Where individual standardized mean difference (SMD) was calculable, random effects meta-analyses were performed to estimate an overall effect size with 95% confidence intervals (CI) comparing active vs passive controls. Heterogeneity was assessed using I² statistic and meta-regression. Funnel asymmetry was evaluated using Egger's test (Prospero registration: CRD42021242940).

RESULTS

24 articles with 25 relevant RCTs were included in the review, of which 11 studies were of high risk of bias. There was an improvement in outcomes favouring the placebo conditions, compared to passive controls, overall (25 studies, SMD 0.24, 95% CI 0.06-0.42, I² = 43%) and in subgroups with anxiety (SMD 0.45, 95% CI 0.07-0.84, I² = 59%) or depression (SMD 0.22, 95% CI 0.04-0.39, I² = 0%). Meta-regression did not show a significant explanation for heterogeneity. Egger's test showed no asymmetry (p = .200).

CONCLUSIONS

A small placebo effect was observed in mental disorders research overall, and in patients with anxiety or depression. These findings should be interpreted with caution in the light of heterogeneity and risk of bias.

Subthreshold depression - concept, operationalisation and epidemiological data. A scoping review

Purpose: In diagnostic systems (e.g., DSM-5, ICD-10), depression is defined categorically. However, the concept of subthreshold depression (SD) has gained increasing interest in recent years. The purpose of the present paper was to review, based on a scoping review, the relevant papers in this field published between October 2011 and September 2020.Materials and methods: Of the 1,160 papers identified, 64 records could be included in further analysis. The scoping review was conducted using both electronic and manual methods.Results: The main result of the analysis is that the operationalisation criteria used are highly heterogeneous, which also leads to very heterogenous epidemiological data.Conclusions: Clear conclusions are not possible scrutinising the reported results. Most definitions seem to be arbitrary, with considerable overlap (e.g., between SD and minor depression). The review also revealed that the impact of SD on quality of life and related parameters appear to be in the range of the respective impact of major depression (MD) and therapeutic approaches might be helpful for SD and also for the prevention of conversion from SD to MD. Keeping the presented difficulties in mind, a proposal for the definition of SD is made in the present paper in order to facilitate the discussion leading to more homogeneous criteria.

Using AI chatbots to provide self-help depression interventions for university students: A randomized trial of effectiveness

BACKGROUND

Depression impacts the lives of a large number of university students. Mobile-based therapy chatbots are increasingly being used to help young adults who suffer from depression. However, previous trials have short follow-up periods. Evidence of effectiveness in pragmatic conditions are still in lack.

OBJECTIVE

This study aimed to compare chatbot therapy to bibliotherapy, which is a widely accepted and proven-useful self-help psychological intervention. The main objective of this study is to add to the evidence of effectiveness for chatbot therapy as a convenient, affordable, interactive self-help intervention for depression.

METHODS

An unblinded randomized controlled trial with 83 university students was conducted. The participants were randomly assigned to either a chatbot test group (n = 41) to receive a newly developed chatbot-delivered intervention, or a bibliotherapy control group (n = 42) to receive a minimal level of bibliotherapy. A set of questionnaires was implemented as measurements of clinical variables at baseline and every 4 weeks for a period of 16 weeks, which included the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder scale (GAD-7), the Positive and Negative Affect Scale (PANAS). The Client Satisfaction Questionnaire-8 (CSQ-8) and the Working Alliance Inventory-Short Revised (WAI-SR) were used to measure satisfaction and therapeutic alliance after the intervention. Participants' self-reported adherence and feedback on the therapy chatbot were also collected.

RESULTS

Participants were all university students (undergraduate students (n = 31), postgraduate students (n = 52)). They were between 19 and 28 years old (mean = 23.08, standard deviation (SD) = 1.76) and 55.42% (46/83) female. 24.07% (20/83) participants were lost to follow-up. No significant group difference was found at baseline. In the intention-to-treat analysis, individuals in the chatbot test group showed a significant reduction in the PHQ-9 scores (F = 22.89; P < 0.01) and the GAD-7 scores (F = 5.37; P = 0.02). Follow-up analysis of completers suggested that the reduction of anxiety was significant only in the first 4 weeks. The WAI-SR scores in the chatbot group were higher compared to the bibliotherapy group (t = 7.29; P < 0.01). User feedback showed that process factors were more influential than the content factors.

CONCLUSIONS

The chatbot-delivered self-help depression intervention was proven to be superior to the minimal level of bibliotherapy in terms of reduction on depression, anxiety, and therapeutic alliance achieved with participants.

An Evaluation of the Acceptability, Appropriateness, and Utility of a Bibliotherapy for Children of Parents With a Mental Illness

BACKGROUND

Children of parents with a mental illness are at higher risk for various psychiatric problems and adaptive difficulties compared to those of parents without mental health problems. Certain preventive psychoeducational interventions target these children to promote their well-being and resilience and prevent the emergence of adaptive difficulties. However, few such interventions have been developed and evaluated specifically for elementary school-aged children of parents with a mental illness.

OBJECTIVES

This study aims to evaluate an interpersonal psychotherapy-based book targeting children living with a parent with a mental illness.

METHODS

The study examines children, parents and psychosocial workers' perception of the acceptability, appropriateness and utility of the book. In total, 22 participants answered online open-ended questions after reading the book.

RESULTS

The book was highly appreciated and positively perceived by the families and psychosocial workers. Results suggest that children, parents and psychosocial workers viewed it as an appropriate and useful tool for supporting children with a parent with a mental illness. The present study reveals that the bibliotherapy appears well adapted to the developmental level of school-age children.

DISCUSSION

This study presents a book that shows promise for supporting the resilience of elementary school-aged children having a parent with a mental illness. Results highlight the importance of tailoring the content and modalities of interventions to the developmental level, needs and preferences of elementary school-aged children. The relevance of a collaborative method is also discussed, thus providing knowledge regarding this type of approach for the development of interventions targeting children.

Broad spectrum micronutrient formulas for the treatment of symptoms of depression, stress, and/or anxiety: a systematic review

Introduction: Vitamin and mineral nutritional supplements are becoming increasingly popular as alternative treatments for anxiety and depression, as issues such as side effects from medication, failure to respond to psychotherapy and workforce limitations pose barriers for successful treatment.Areas covered: This review covered double-blind, randomized controlled trials (DBRCTs) testing formulas including at least four vitamins and/or minerals used for the treatment of symptoms of anxiety, stress, or depression in adults not currently taking medication for psychiatric difficulties.Expert opinion: The majority of the 23 trials reviewed were conducted on people without psychological difficulties, limiting the generalizability of the results in people with diagnosed mood and anxiety difficulties. Sixteen studies demonstrated positive effects for symptoms of anxiety, depression, or stress. Micronutrient supplementation in healthy nonclinical adults has limited benefits for mood and anxiety symptoms, although may convey some subtle general improvements. The evidence for adults with physical or mental ill health is more positive although limited by small samples and variability in nutrients studied. Broad-spectrum nutrient products may be more effective than a selected few. While an effect of micronutrients cannot be dismissed, the variability of the studies makes it extremely challenging to identify specific treatment benefits.

Interventions for common mental health problems among university and college students: A systematic review and meta-analysis of randomized controlled trials

Common mental health problems (CMHPs), such as depression, anxiety disorder, obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD) are internalizing disorders with high comorbidity. University and college students are under many stressors and transitional events, and students fall within the age range when CMHPs are at their developmental peak. Compared to the expanded effort to explore and treat CMHPs, there has been no a meta-analysis that comprehensively reviewed the interventions for CMHPs and examined the effects of interventions for CMHPs in college students. The objective of this review is to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) examining interventions for CMHPs among university and college students and to estimate their post-intervention effect size (ES), as well as follow-up ES, for depression, anxiety disorder, OCD and PTSD separately. Meta-analytic procedures were conducted in accordance with PRISMA guidelines. We reviewed 7768 abstracts from which 331 full-text articles were reviewed and 51 RCTs were included in the analysis. We found moderate effect sizes for both depression (Hedges' g = -0.60) and anxiety disorder (Hedges' g = -0.48). There was no evidence that existing interventions for OCD or PTSD were effective in this population. For interventions with high number of papers, we performed subgroup analysis and found that cognitive behavioral therapy (CBT) and mindfulness-based interventions were effective for both depression and generalized anxiety disorder (GAD), and attention/perception modification was effective for GAD; other interventions (i.e. art, exercise and peer support) had the highest ES for both depression and GAD among university and college students.

The evaluation of a continuing professional development package for primary care dentists designed to reduce stress, build resilience and improve clinical decision-making

Introduction Stress and burnout are widely accepted as a problem for primary care dental practitioners. Previous programmes to address this issue have met with some success. Burnout is associated with poor coping skills and emotion regulation, and increased rates of clinical errors. Anxiety is associated with poor decision-making and is thought to be associated with poor clinical decision-making. Attempts to improve decision-making use increasing meta-awareness and review of thinking processes. Bibliotherapy is an effective method of delivering cognitive behavioural therapy as self-help or guided self-help (with some therapist input) formats.Objective To evaluate the efficacy of a specially designed CPD package which was designed to improve coping skills, build resilience and reduce the impact of anxiety on dentists' clinical decision-making.Design A multi-centred quasi-experiment.Setting Lincolnshire and Nottinghamshire (England) 2014.Materials and methods Thirty-five volunteer primary care dentists used two versions (self-help [SH] and guided self-help [GSH], which included a 3 hour workshop) of a specially written cognitive behavioural therapy bibliotherapy programme designed to improve well-being and decision-making.Main Outcome Measures The main outcome measures were dentists' burnout, depression, anxiety, stress and decision-making style. Data were also collected on use and evaluation of the programme.Results At 6 weeks there was a clinically and statistically significant reduction in depression, anxiety and stress levels, a statistically significant reduction in burnout (emotional exhaustion) and hypervigilant decision-making, and an increase in personal achievement. The improvements in depression, stress, emotional exhaustion and hypervigilant decision-making were maintained at 6 months. Dentists were overwhelmingly positive in their evaluation of the project and used most of its contents.Conclusion With the caveat of small numbers and the lack of a no-treatment control, this project demonstrated that a self-help package can be highly acceptable to dentists and, in the short-to-medium term, improve dentists' well-being and decision-making with implications for patient safety.

Integrating situation-specific dysfunctional expectations and dispositional optimism into the cognitive model of depression - A path-analytic approach

BACKGROUND

Dysfunctional expectations are considered to be core features of mental disorders and, in particular, major depression. The aim of the present study was to integrate two important types of expectations into the cognitive model of depression: situation-specific dysfunctional expectations (SDE) and dispositional optimism (DO). It was hypothesized that the influence of both DO and intermediate beliefs (IB) on depressive symptoms would be mediated via SDE.

METHODS

We examined 95 individuals (age M = 40.7, 68.1% female) with a diagnosed major depressive disorder from two inpatient clinics and one outpatient clinic. Measurements used in the study included the Depressive Expectations Scale, Dysfunctional Attitudes Scale, Life Orientation Test Revised, and Beck's Depression Inventory-II. Relationships between the constructs were analyzed using path-analytic models with bias-corrected bootstrapping confidence intervals.

RESULTS

Results indicate that the effect of IB on depressive symptoms was fully mediated via SDE, while the effect of DO on depressive symptoms was partly mediated via SDE. IB and DO moderately correlated with each other.

LIMITATIONS

Due to the cross-sectional design of the study, it is not possible to draw unambiguous conclusions regarding the causality of the suggested relationships.

CONCLUSIONS

The present study stresses the crucial role of dysfunctional expectations for major depression. Moreover, it reveals that SDEs as expectations with a high level of situational specificity may pose an important link between global cognitions and depressive symptoms. Given this situational specificity, SDEs are amenable to disconfirmation through behavioral experiments and may therefore be a promising target for cognitive-behavioral interventions.

The long-term effects of bibliotherapy in depression treatment: Systematic review of randomized clinical trials

OBJECTIVE

Literature shows bibliotherapy can be helpful for moderate depression treatment. The aim of this systematic review is to verify the long-term effects of bibliotherapy.

METHODS

After bibliographic research, we included RCTs articles about bibliotherapy programme treatment of depression published in English language between 1990 and July 2017. All RCTs were assessed with Cochrane's Risk of Bias tool.

RESULTS

Ten articles (reporting 8 studies involving 1347 subjects) out of 306 retrieved results were included. All studies analyze the effects of bibliotherapy after follow-up periods ranging from 3months to 3years and show quiet good quality in methods and analyses. The treatment was compared to standard treatments or no intervention in all studies. After long-term period follow-ups, six studies, including adults, reported a decrease of depressive symptoms, while four studies including young people did not show significant results.

CONCLUSION

Bibliotherapy appears to be effective in the reduction of adults depressive symptoms in the long-term period, providing an affordable prompt treatment that could reduce further medications. The results of the present review suggest that bibliotherapy could play an important role in the treatment of a serious mental health issue. Further studies should be conducted to strengthen the evidence of bibliotherapy's efficacy.

Reducing depressive symptomatology with a smartphone app: study protocol for a randomized, placebo-controlled trial

BACKGROUND

Depression has become one of the leading contributors to the global disease burden. Evidence-based treatments for depression are available, but access to them is still limited in some instances. As technology has become more integrated into mental health care, computerized cognitive behavioral therapy (CBT) protocols have become available and have been recently transposed to mobile environments (e.g., smartphones) in the form of "apps." Preliminary research on some depression apps has shown promising results in reducing subthreshold or mild to moderate depressive symptoms. However, this small number of studies reports a low statistical power and they have not yet been replicated. Moreover, none of them included an active placebo comparison group. This is problematic, as a "digital placebo effect" may explain some of the positive effects documented until now. The aim of this study is to test a newly developed mobile app firmly grounded in the CBT theory of depression to determine whether this app is clinically useful in decreasing moderate depressive symptoms when compared with an active placebo. Additionally, we are interested in the app's effect on emotional wellbeing and depressogenic cognitions.

METHODS/DESIGN

Romanian-speaking adults (18 years and older) with access to a computer and the Internet and owning a smartphone are included in the study. A randomized, three-arm clinical trial is being conducted (i.e., active intervention, placebo intervention and delayed intervention). Two hundred and twenty participants with moderate depressive symptoms (i.e., obtaining scores >9 and ≤16 on the Patient Health Questionnaire, PHQ-9) will be randomized to the three conditions. Participants undergoing therapy, presenting serious mental health problems, or legal or health issues that would prevent them from using the app, as well as participants reporting suicidal ideation are excluded. Participants randomized to the active and placebo interventions will use the smartphone app for 6 weeks. A short therapist check-in via phone will take place every week. Participants in the delayed-intervention condition will be given access to the app after 6 weeks from randomization. The primary outcome is the level of depressive symptomatology. The intervention delivered through the app to the active condition includes psychoeducational materials and exercises based on CBT for depression, while the placebo intervention uses a sham version of the app (i.e., similar structure of courses and exercises).

DISCUSSION

To our knowledge, this study protocol is the first to test the efficacy of a smartphone app for depressive symptomatology in the form of a randomized controlled trial (RCT) that includes an active placebo condition. As such, this can substantially add to the body of evidence supporting the use of apps designed to decrease depression.

Using a smartphone app to reduce cognitive vulnerability and mild depressive symptoms: Study protocol of an exploratory randomized controlled trial

Background

Depression is a major challenge worldwide, with significant increasing personal, economic, and societal costs. Although empirically supported treatments have been developed, they are not always available for patients in routine clinical care. Therefore, we need effective and widely accessible strategies to prevent the onset of the very first depressive symptoms. Mental health apps could prove a valuable solution for this desideratum. Although preliminary research has indicated that such apps can be useful in treating depression, no study has attempted to test their utility in preventing depressive symptoms. The aim of this exploratory study is to contrast the efficacy of a smartphone app in reducing cognitive vulnerability and mild depressive symptoms, as risk factors for the onset of depression, against a wait-list condition. More specifically, we aim to test an app designed to (1) decrease general cognitive vulnerability and (2) promote engagement in protective, adaptive activities, while (3) counteracting (through gamification and customization) the tendency of premature dropout from intervention.

Methods/design

Romanian-speaking adults (18 years and older) with access to a computer and the Internet and who own a smartphone are included in the study. Two parallel randomized clinical trials are conducted: in the first one, 50 participants free of depressive symptoms (i.e., who obtain scores ≤4 on the Patient Health Questionnaire, PHQ-9) will be included, while in the second one 50 participants with minimal depressive symptoms (i.e., who obtain PHQ-9 scores between 5 and 9) will be included. Participants undergoing therapy, presenting with substance abuse problems, psychotic symptoms, and organic brain disorders, or serious legal or health issues that would prevent them from using the app, as well as participants reporting suicidal ideation are excluded. Participants randomized to the active intervention will autonomously use the smartphone app for 4 weeks, while the others will be given access to the app after 4 weeks from randomization. The primary outcomes are (1) cognitive vulnerability factors as defined within the cognitive behavioral therapy (CBT) paradigm (i.e., dysfunctional cognitions, irrational beliefs, and negative automatic thoughts) (for the first trial), and (2) level of depressive symptomatology (for the second trial). The app includes self-help materials and exercises based on CBT for depression, presented in a tailored manner and incorporating gamification elements aimed at boosting motivation to use the app.

Discussion

This study protocol is the first to capitalize on the ubiquity of smartphones to large-scale dissemination of CBT-based strategies aimed at preventing depression in non-clinical populations.

Cultural Adaptation of Minimally Guided Interventions for Common Mental Disorders: A Systematic Review and Meta-Analysis

BACKGROUND

Cultural adaptation of mental health care interventions is key, particularly when there is little or no therapist interaction. There is little published information on the methods of adaptation of bibliotherapy and e-mental health interventions.

OBJECTIVE

To systematically search for evidence of the effectiveness of minimally guided interventions for the treatment of common mental disorders among culturally diverse people with common mental disorders; to analyze the extent and effects of cultural adaptation of minimally guided interventions for the treatment of common mental disorders.

METHODS

We searched Embase, PubMed, the Cochrane Library, and PsycINFO for randomized controlled trials that tested the efficacy of minimally guided or self-help interventions for depression or anxiety among culturally diverse populations. We calculated pooled standardized mean differences using a random-effects model. In addition, we administered a questionnaire to the authors of primary studies to assess the cultural adaptation methods used in the included primary studies. We entered this information into a meta-regression to investigate effects of the extent of adaptation on intervention efficacy.

RESULTS

We included eight randomized controlled trials (RCTs) out of the 4911 potentially eligible records identified by the search: four on e-mental health and four on bibliotherapy. The extent of cultural adaptation varied across the studies, with language translation and use of metaphors being the most frequently applied elements of adaptation. The pooled standardized mean difference for primary outcome measures of depression and anxiety was -0.81 (95% CI -0.10 to -0.62). Higher cultural adaptation scores were significantly associated with greater effect sizes (P=.04).

CONCLUSIONS

Our results support the results of previous systematic reviews on the cultural adaptation of face-to-face interventions: the extent of cultural adaptation has an effect on intervention efficacy. More research is warranted to explore how cultural adaptation may contribute to improve the acceptability and effectiveness of minimally guided psychological interventions for common mental disorders.

Cognitive evolutionary therapy for depression: a case study

KEY CLINICAL MESSAGE

We present an evolutionary-driven cognitive-behavioral intervention for a moderately depressed patient. Standard cognitive and behavioral therapy techniques focused on the patient's perfectionistic and self-downing beliefs, while novel, evolutionary-informed techniques were used to guide behavioral activation and conceptualize secondary emotional problems related to anger. The treatment reduced depressive symptomatology and increased evolutionary fitness.

Cognitive bibliotherapy and memory training for older adults with depressive symptoms

OBJECTIVES

Substantial evidence indicates that depressed participants perform more poorly than nondepressed participants on a number of memory tasks. Cognitive deficits associated with depression (i.e., poor allocation of attention, poor encoding strategies), may help explain why depressed older adults are particularly prone to evidence poorer memory performance.

METHOD

The present study compared the impact of two self-administered treatment protocols, cognitive bibliotherapy for depression plus memory training (CBT + MT) and cognitive bibliotherapy alone (CBT), to a wait-list control condition on measures of memory functioning and depression in a group of older adults experiencing depressive symptoms and memory complaints.

RESULTS

Results provide partial support for CBT as a treatment for depressive symptoms; however, memory training augmentation did not produce improvements.

CONCLUSION

Suggestions for improving retention of older adults in self-administered treatments are discussed.

Evolutionary cognitive therapy versus standard cognitive therapy for depression: a protocol for a blinded, randomized, superiority clinical trial

BACKGROUND

Depression is estimated to become the leading cause of disease burden globally by 2030. Despite existing efficacious treatments (both medical and psychotherapeutic), a large proportion of patients do not respond to therapy. Recent insights from evolutionary psychology suggest that, in addition to targeting the proximal causes of depression (for example, targeting dysfunctional beliefs by cognitive behavioral therapy), the distal or evolutionary causes (for example, inclusive fitness) should also be addressed. A randomized superiority trial is conducted to develop and test an evolutionary-driven cognitive therapy protocol for depression, and to compare its efficacy against standard cognitive therapy for depression.

METHODS/DESIGN

Romanian-speaking adults (18 years or older) with elevated Beck Depression Inventory (BDI) scores (>13), current diagnosis of major depressive disorder or major depressive episode (MDD or MDE), and MDD with comorbid dysthymia, as evaluated by the Structured Clinical Interview for DSM-IV (SCID), are included in the study. Participants are randomized to one of two conditions: 1) evolutionary-driven cognitive therapy (ED-CT) or 2) cognitive therapy (CT). Both groups undergo 12 psychotherapy sessions, and data are collected at baseline, mid-treatment, post-treatment, and the 3-month follow-up. Primary outcomes are depressive symptomatology and a categorical diagnosis of depression post-treatment.

DISCUSSION

This randomized trial compares the newly proposed ED-CT with a classic CT protocol for depression. To our knowledge, this is the first attempt to integrate insights from evolutionary theories of depression into the treatment of this condition in a controlled manner. This study can thus add substantially to the body of knowledge on validated treatments for depression.
