Digitally Delivered Psychological Interventions for Anxiety Disorders: a Comprehensive Review

Patients' and Therapists' Views of Integrated Online CBT for Depression

BACKGROUND

CBT is an effective treatment for depression, but access varies across the United Kingdom. Online CBT increases access. The INTERACT platform was designed to support patient engagement in CBT, enabling therapists to deliver high-intensity CBT via typed instant messaging and allowing patients and therapists access to an integrated online library of resources during and between sessions.

METHODS

The INTERACT trial aimed to evaluate this integrated approach to delivering CBT for primary care patients with depression. A nested qualitative study was conducted within the trial. Interviews were conducted with 20 patients who received the intervention, 9 therapists who delivered it and 3 therapist supervisors. Data were analysed using thematic analysis.

RESULTS

The combination of receiving support from a therapist and having access to integrated online CBT resources enabled patients to better manage their depression. Platform benefits included the opportunity to review transcripts to clarify how to complete homework tasks and track progress in managing their depression. The typing process allowed reflection and a focused discussion. However, less could be covered than during an in-person session, which reduced therapists' expectations around goal setting. Patients who did not complete therapy struggled with the typing and found the CBT approach too demanding.

CONCLUSION

Findings highlight the importance of establishing patient and therapist goals and expectations about what can be achieved in CBT mediated by typing. Some patients are comfortable communicating via typing and are motivated to utilise online resources in between sessions. Exploring the benefits and challenges of typed CBT with patients will enable them to make an informed choice about referral for this novel approach to therapy.

Digital Lifestyle Interventions for Young People With Mental Illness: A Qualitative Study Among Mental Health Care Professionals

BACKGROUND

Given the physical health disparities associated with mental illness, targeted lifestyle interventions are required to reduce the risk of cardiometabolic disease. Integrating physical health early in mental health treatment among young people is essential for preventing physical comorbidities, reducing health disparities, managing medication side effects, and improving overall health outcomes. Digital technology is increasingly used to promote fitness, lifestyle, and physical health among the general population. However, using these interventions to promote physical health within mental health care requires a nuanced understanding of the factors that affect their adoption and implementation.

OBJECTIVE

Using a qualitative design, we explored the attitudes of mental health care professionals (MHCPs) toward digital technologies for physical health with the goal of illuminating the opportunities, development, and implementation of the effective use of digital tools for promoting healthier lifestyles in mental health care.

METHODS

Semistructured interviews were conducted with MHCPs (N=13) using reflexive thematic analysis to explore their experiences and perspectives on using digital health to promote physical health in youth mental health care settings.

RESULTS

Three overarching themes from the qualitative analysis are reported: (1) motivation will affect implementation, (2) patients' readiness and capability, and (3) reallocation of staff roles and responsibilities. The subthemes within, and supporting quotes, are described.

CONCLUSIONS

The use of digital means presents many opportunities for improving the provision of physical health interventions in mental health care settings. However, given the limited experience of many MHCPs with these technologies, formal training and additional support may improve the likelihood of implementation. Factors such as patient symptomatology, safety, and access to technology, as well as the readiness, acceptability, and capability of both MHCPs and patients to engage with digital tools, must also be considered. In addition, the potential benefits of data integration must be carefully weighed against the associated risks.

The Impact of Digital Mental Health Services on Loneliness and Mental Health: Results from a Prospective, Observational Study

BACKGROUND

Loneliness has increased since the COVID-19 pandemic and negatively impacts mental health. This study examined relationships between loneliness and mental health among adults using a digital mental health platform.

METHODS

A purposive sample of 919 participants (97% response rate) who were newly enrolled in the platform completed a survey on loneliness, depression, anxiety, well-being, stress, social support, and comorbidities at baseline and 3 months. Platform engagement was tracked during this period. We examined baseline differences between lonely and non-lonely participants; associations between loneliness, mental health symptoms, and comorbidities; and changes in loneliness and mental health through engagement in any form of care.

RESULTS

At baseline, 57.8% of the sample were categorized as lonely. Loneliness was associated with younger age, fewer years of education, and the presence of a comorbidity (p values < .05). Baseline loneliness was associated with greater depression, anxiety, and stress and lower well-being and social support (ps < .001). The percentage of lonely participants decreased at follow-up (57.6% to 52.9%, p = .03). Those who improved in loneliness improved in mental health symptoms, well-being, and social support (ps < .001). Lonely participants who engaged in any form of care reported a greater reduction in loneliness than those who did not engage (p = .04).

CONCLUSIONS

This study confirms previous findings of the high prevalence of loneliness among adults and risk factors for increased loneliness. Findings highlight the potential of digital platforms to reach lonely individuals and alleviate loneliness through remote mental health support.

Population density and receipt of care for common mental disorders: a cross-sectional analysis of English household data from the 2014 Adult Psychiatric Morbidity Survey

OBJECTIVES

People living in less urban areas in the UK may have reduced access to mental healthcare compared with people in urban areas. Although this was not reported in the 2000 Adult Psychiatric Morbidity Survey (APMS) data, subsequent changes to mental health provision and economic recession may have impacted care inequalities. We re-examined this, hypothesising that those living in less urban areas of England received less antidepressant medication and psychological interventions, compared with those living in urban areas, after adjusting for covariates including common mental disorders (CMDs) and socioeconomic status.

DESIGN

National cross-sectional study.

SETTING

Households in England.

PARTICIPANTS

We analysed data from 7455 participants aged 16 and above from the 2014 English APMS.

EXPOSURES

Residence in an urban or less urban area.

PRIMARY OUTCOME

Current receipt of any antidepressant medication or any psychological intervention.

RESULTS

Participants living in less urban areas were half as likely to be in receipt of any psychological intervention relative to those living in urban areas (adjusted OR (aOR) 0.49; 95% CI 0.30 to 0.79; p=0.004). There was no association between urbanisation and antidepressant receipt (aOR 1.01; 95% CI 0.81 to 1.25; p=0.944).

CONCLUSION

People living in less urban areas have a lower likelihood of being in receipt of psychological treatment for CMDs, which may indicate barriers to care access. Our findings differ from the results of a study using a comparable sample conducted 14 years previously. While Improving Access to Psychological Therapies services have increased therapy access nationwide, this may have had more impact in urban areas, potentially widening urban/rural inequalities. Further research is needed to understand how to address such geographical inequalities in access to mental healthcare.

Digital-Based Interventions for Complex Post-Traumatic Stress Disorder: A Systematic Literature Review

Research has shown that complex post-traumatic stress disorder (cPTSD) differs from post-traumatic stress disorder (PTSD) on core symptoms relating to the individual's sense of self, and this has driven the need for treatment approaches to address these specific features of cPTSD. The COVID-19 pandemic has led to the increased use of digital-based interventions (DBIs) to treat mental illnesses, including trauma-related disorders. However, while evidence for the use of DBIs for PTSD has previously been synthesized, the current review is the first synthesis of research on the use of DBIs for cPTSD. A systematic search of Scopus, PsychINFO, and EBSCOhost was conducted, using search terms targeting "cPTSD" and "DBIs," to identify research on the use of DBIs to treat cPTSD symptoms. Ten papers were identified, which provided preliminary evidence for the efficacy of DBIs to reduce cPTSD symptoms. Further, DBIs were reported as acceptable by individuals with a history of complex trauma. The paper also provides insight into the therapeutic approaches adopted, digital modalities utilized, safety measures included, and whether/to what degree support was provided. While DBIs show promise for treating cPTSD, there is substantial room for advancement of the empirical evidence base for these approaches. Both clinical and research-based recommendations are provided separately.

Two decades of digital interventions for anxiety disorders: a systematic review and meta-analysis of treatment effectiveness

BACKGROUND

Digital interventions for anxiety disorders are a promising solution to address barriers to evidence-based treatment access. Precise and powerful estimates of digital intervention effectiveness for anxiety disorders are necessary for further adoption in practice. The present systematic review and meta-analysis examined the effectiveness of digital interventions across all anxiety disorders and specific to each disorder v. wait-list and care-as-usual controls.

METHODS

A systematic search of bibliographic databases identified 15 030 abstracts from inception to 1 January 2020. Forty-seven randomized controlled trials (53 comparisons; 4958 participants) contributed to the meta-analysis. Subgroup analyses were conducted by an anxiety disorder, risk of bias, treatment support, recruitment, location and treatment adherence.

RESULTS

A large, pooled effect size of g = 0.80 [95% Confidence Interval: 0.68-0.93] was found in favor of digital interventions. Moderate to large pooled effect sizes favoring digital interventions were found for generalized anxiety disorder (g = 0.62), mixed anxiety samples (g = 0.68), panic disorder with or without agoraphobia (g = 1.08) and social anxiety disorder (g = 0.76) subgroups. No subgroups were significantly different or related to the pooled effect size. Notably, the effects of guided interventions (g = 0.84) and unguided interventions (g = 0.64) were not significantly different. Supplemental analysis comparing digital and face-to-face interventions (9 comparisons; 683 participants) found no significant difference in effect [g = 0.14 favoring digital interventions; Confidence Interval: -0.01 to 0.30].

CONCLUSION

The precise and powerful estimates found further justify the application of digital interventions for anxiety disorders in place of wait-list or usual care.

Psychotherapies and digital interventions for OCD in adults: What do we know, what do we need still to explore?

BACKGROUND

Despite significant advances in the understanding and treatment of obsessive compulsive disorder (OCD), current treatment options are limited in terms of efficacy for symptom remission. Thus, assessing the potential role of iterative or alternate psychotherapies is important. Also, the potential role of digital technologies to enhance the accessibility of these therapies, should not be underestimated. We also need to embrace the idea of a more personalized treatment choice, being cognisant of clinical, genetic and neuroimaging predictors of treatment response.

PROCEDURES

Non-systematic review of current literature on emerging psychological and digital therapies for OCD, as well as of potential biomarkers of treatment response.

FINDINGS

A number of 'third wave' therapies (e.g., Acceptance and Commitment Therapy, Mindfulness-Based Cognitive Therapy) have an emerging and encouraging evidence base in OCD. Other approaches entail employment of elements of other psychotherapies such as Dialectical Behaviour Therapy; or trauma-focussed therapies such as Eye Movement Desensitisation and Reprocessing, and Imagery Rescripting and Narrative Therapy. Further strategies include Danger Ideation Reduction Therapy and Habit Reversal. For these latter approaches, large-scale randomised controlled trials are largely lacking, and the precise role of these therapies in treating people with OCD, remains to be clarified. A concentrated 4-day program (the Bergen program) has shown promising short- and long-term results. Exercise, music, and art therapy have not been adequately tested in people with OCD, but may have an adjunctive role. Digital technologies are being actively investigated for enhancing reach and efficacy of psychological therapies for OCD. Biomarkers, including genetic and neuroimaging, are starting to point to a future with more 'personalised medicine informed' treatment strategizing for OCD.

CONCLUSIONS

There are a number of potential psychological options for the treatment of people with OCD who do not respond adequately to exposure/response prevention or cognitive behaviour therapy. Adjunctive exercise, music, and art therapy might be useful, albeit the evidence base for these is very small. Consideration should be given to different ways of delivering such interventions, including group-based, concentrated, inpatient, or with outreach, where appropriate. Digital technologies are an emerging field with a number of potential applications for aiding the treatment of OCD. Biomarkers for treatment response determination have much potential capacity and deserve further empirical testing.

Digital Health Interventions for Delivery of Mental Health Care: Systematic and Comprehensive Meta-Review

BACKGROUND

The COVID-19 pandemic has shifted mental health care delivery to digital platforms, videoconferencing, and other mobile communications. However, existing reviews of digital health interventions are narrow in scope and focus on a limited number of mental health conditions.

OBJECTIVE

To address this gap, we conducted a comprehensive systematic meta-review of the literature to assess the state of digital health interventions for the treatment of mental health conditions.

METHODS

We searched MEDLINE for secondary literature published between 2010 and 2021 on the use, efficacy, and appropriateness of digital health interventions for the delivery of mental health care.

RESULTS

Of the 3022 records identified, 466 proceeded to full-text review and 304 met the criteria for inclusion in this study. A majority (52%) of research involved the treatment of substance use disorders, 29% focused on mood, anxiety, and traumatic stress disorders, and >5% for each remaining mental health conditions. Synchronous and asynchronous communication, computerized therapy, and cognitive training appear to be effective but require further examination in understudied mental health conditions. Similarly, virtual reality, mobile apps, social media platforms, and web-based forums are novel technologies that have the potential to improve mental health but require higher quality evidence.

CONCLUSIONS

Digital health interventions offer promise in the treatment of mental health conditions. In the context of the COVID-19 pandemic, digital health interventions provide a safer alternative to face-to-face treatment. However, further research on the applications of digital interventions in understudied mental health conditions is needed. Additionally, evidence is needed on the effectiveness and appropriateness of digital health tools for patients who are marginalized and may lack access to digital health interventions.

Efficacy of intensive CBT telehealth for obsessive-compulsive disorder during the COVID-19 pandemic

Despite evidence for the effectiveness of cognitive behavioral therapy (CBT) for obsessive-compulsive disorder (OCD), many individuals with OCD lack access to needed behavioral health treatment. Although some literature suggests that virtual modes of treatment for OCD are effective, it remains unclear whether intensive programs like partial hospitalization and intensive outpatient programs (PHP and IOPs) can be delivered effectively over telehealth (TH) and within the context of a global pandemic. Limited extant research suggests that clinicians perceive attenuated treatment response during the pandemic. The trajectory and outcomes of two matched samples were compared using linear mixed modeling: a pre-COVID in-person (IP) sample (n = 239) and COVID TH sample (n = 239). Findings suggested that both modalities are effective at treating OCD and depressive symptoms, although the pandemic TH group required an additional 2.6 treatment days. The current study provides evidence that PHP and IOP treatment delivered via TH during the COVID-19 pandemic is approximately as effective as pre-pandemic IP treatment and provides promising findings for the future that individuals with complicated OCD who do not have access to IP treatment can still experience significant improvement in symptoms through TH PHP and IOP treatment during and potentially after the pandemic.

Evaluating the feasibility and acceptability of a mobile-based health technology for smoking cessation: Mobile Anxiety Sensitivity Program

OBJECTIVES

Cigarette smoking is the leading preventable cause of death and disability. Although most US smokers want to quit, more than 95% of cessation attempts end in relapse within 6 months. To improve cessation outcomes, research has turned to targetable mechanisms, such as anxiety sensitivity (AS), which maintain smoking behaviour, impede cessation success, and can be effectively targeted in the context of psychosocial interventions. Although integrated treatment programmes that address AS reduction in the context of smoking cessation have demonstrated promising results, presently, no mobile, technology-based integrated treatment exists to expressly address smoking and AS. The current study evaluated the initial feasibility and acceptability of a mobile smoking cessation intervention, Mobile Anxiety Sensitivity Program for smoking (MASP).

METHODS

Participants were 15 daily adult combustible cigarette smokers (females n = 6, M_age  = 46.5 years, SD = 13.3) who completed a 6-week total intervention period (baseline visit, 2 weeks pre-quit, 4 weeks post-quit, follow-up visit).

RESULTS

Most participants (N = 12) completed the full 6-week intervention, and participant engagement with MASP was high. Participants reported that MASP was acceptable. Biochemical verification of smoking abstinence indicated 25% of smokers were abstinent for at least 24 hr prior to the in-person 4 weeks post-quit follow-up visit.

CONCLUSIONS

Findings indicated that MASP has the potential to provide effective assistance to those wanting to quit cigarettes.

PRACTITIONER POINTS

Mobile-based smoking cessation interventions may be a promising treatment option, particularly for those of lower socio-economic status. Targeting AS in the context of a mobile-based smoking cessation app may be a viable way to improve smoking cessation success and treatment outcome. Due to the pilot nature of this study, there was no control group. Thus, comparative conclusions and generalizability based on the current study must be made with caution.

A qualitative study of patients’ experiences and acceptance of computerised cognitive behavioural therapy in primary care, Scotland

Computerised cognitive behavioural therapy (CCBT) has been made available within the National Health Service (NHS) across Scotland as an alternative treatment for mild to moderate anxiety and depression. However, the provision of CCBT services is still limited in the NHS, possibly affecting delivery of this computer-aided therapy to patients and inhibiting acceptance and uptake of this intervention. This paper reports on the qualitative exploration of patients’ experiences and acceptance of one CCBT programme delivering computer-assisted therapy (Beating the Blues: BTB), examining particularly the point of referral, access to treatment, and support. Thematic analysis was conducted on semi-structured face-to-face and email interviews with 33 patients at different NHS organisations across Scotland. Data analysis generated six key themes which illustrated patients’ experiences relating to referral and access to the treatment, and the challenges they faced: (1) information dissemination; (2) expectations and the impact of waiting for BTB; (3) impact of locations on experience of BTB; (4) preference for home access; (5) desire for better human support; and (6) desire for additional application support features. The findings highlighted that better methods of implementing and delivering such CCBT services together with the design of the technological interventions are vital to the success of these services.

Helpful explanatory models for somatoform symptoms (HERMES): study protocol of a randomised mixed-methods pilot trial

INTRODUCTION

Persistent somatic symptoms (PSS) are common both in the general population and primary care. They are bothersome in terms of psychological and somatic symptom burden. Health professionals often struggle with communication, as there is a lack of scientifically supported explanatory models for PSS or a focus merely on somatic aspects of the complaints, which both frustrate patients' needs. The objective of the present study is therefore to develop a psychoeducational intervention based on a current evidence-based explanatory model, to examine its feasibility and form the basis for a large-scale randomised controlled trial.

METHODS AND ANALYSIS

In a randomised controlled mixed-methods pilot trial, 75 adult psychosomatic outpatients with PSS (duration of symptoms ≥6 months) and accompanying psychological (Somatic Symptom B-Criteria Scale total score ≥18) and somatic symptom burden (Patient Health Questionnaire-15 score >10) and no prior psychosomatic treatment will be eligible. Participants will be presented with either the explanatory model without (intervention group 1, n=25) or with elements of personalisation (intervention group 2, n=25). Participants in the control group (n=25) will receive information on current PSS guidelines. Participants will be blinded to group assignment and interventions will be shown on tablet computers at the outpatient clinic. After 1 month, qualitative follow-up telephone interviews will be conducted. As primary outcomes, mean changes in psychological and somatic symptom burden will quantitatively be compared between groups, respectively. Behavioural change mechanisms and feasibility of the three interventions will be evaluated using quantitative and qualitative measures.

ETHICS AND DISSEMINATION

Ethics approval has been granted by the medical ethics board of the Hamburg Medical Chamber (PV5653). Results from this study will be published in peer-reviewed journals and presented at national and international conferences.

Digital Interventions for PTSD Symptoms in the General Population: a Review

There has been a significant development of digital interventions for the treatment of Post-Traumatic Symptom Disorder (PTSD) over the past two decades. However, the majority of research has examined their clinical efficacy for military service members and veteran populations whereas community-based trauma survivors have received significantly less attention. Their effectiveness for this population, therefore, remains unclear. The aim of this review was to evaluate the effectiveness of digitally delivered psychological therapies to alleviate PTSD symptomatology in the general population. Findings showed that digitally delivered Cognitive Behavioural Therapy (iCBT) produced more consistently significant improvements in PTSD symptoms, compared to interapy, expressive writing, psychoeducation, mindfulness, cognitive tasks and psychosocial interventions. iCBT - associated improvements were also independent of the focus (i.e. trauma vs. non-trauma) of the intervention, the provision of therapeutic support (e.g. guided vs. unguided), type of feedback (e.g. automated vs. individualised) or the number of sessions provided. Nevertheless, the number of included studies for subgroup analyses was relatively low. Digital interventions have an enormous potential to improve accessibility, efficiency, clinical effectiveness and personalisation of mental health interventions. Future research is needed to investigate further the use of a wider range of therapeutic approaches across different clinical and subclinical groups and settings and test the impact of these interventions (or components) against a wider range of comparison conditions (e.g. face to face CBT) with optimal power.

Are digital interventions effective in reducing suicidal ideation and self-harm? A systematic review

Background: There is a significant lack of outcomes research examining the effectiveness of digital interventions for reducing suicidal ideation and self-harm.Aims: To systematically review the effectiveness of digital interventions for reducing suicidal ideation and self-harm in adult populations. The possible mediating effects of depression are also discussed.Methods: The databases Pubmed, Medline, PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, IEEEXplore, ACM and CRESP were searched. Only randomised controlled trials (RCTs) were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Studies were assessed for methodological quality and risk of bias using standard assessment criteria.Results: Fourteen RCTs were reviewed, reporting data on 3455 participants. Although findings were more consistent for the effectiveness of online Cognitive Behavioural Therapy (CBT), Mindfulness-Based CBT and Dialectical Behavioural Therapy, there was insufficient research to consider any as evidence-based treatments for suicidal ideation and self-harm.Conclusions: Digital interventions for suicidal ideation and self-harm can be a safe and acceptable option for individuals unwilling or unable to access face-to-face interventions. However, further research is needed to understand the types of interventions that could support people and the risk-benefit ratio of digital interventions for these individuals.
