Internet-delivered cognitive behavioral therapy for panic disorder with or without agoraphobia: a systematic review and meta-analysis

Easing Panic: The Effect of an Online Psychoeducational Program on Panic Symptoms, Anxiety, and Quality of Life Among People Experiencing Panic Attacks

Panic attacks (PAs) are intense episodes of anxiety with severe physical symptoms that can impair an individual's social and occupational functions. Psychoeducation, a structured educational intervention, aims to improve various health aspects, including mental disorders. Delivering psychoeducation via the Internet can overcome barriers to accessing mental health treatment. This study examined the effectiveness of online psychoeducation on panic symptoms, anxiety, and quality of life (QOL) among people experiencing PAs. In this quasi-experimental design, 157 participants with PAs were recruited, and 136 eligible participants were allocated to treatment and control groups. The treatment group received an eight-session online psychoeducational program over 8 weeks, while the control group received reading materials. Outcome variables, including panic symptoms, anxiety, and QOL, were measured at baseline, 1-week post-intervention, and at 8-week follow-up using the Panic Disorder Dimensional (PD-D) scale, the Generalized Anxiety Disorder (GAD-7) scale, and the World Health Organization Quality of Life-BREF (WHOQOL-BREF), respectively. In the treatment group, the split-plot ANOVA showed a significant reduction in panic symptoms [F(1, 98) = 18.86, p < 0.01] and anxiety [F(1, 98) = 18.241, p < 0.01] compared to the control group. However, the intervention did not significantly affect QOL [F(1, 98) = 0.278, MSE = 153.007, p > 0.05]. The online psychoeducational program effectively reduced panic symptoms and anxiety levels but did not significantly impact QOL. Internet-based interventions, including psychoeducation, can improve access to mental health treatment, potentially reducing the treatment gap and enhancing overall mental health outcomes.

Assessing the effectiveness of internet-based interventions for mental health outcomes: an umbrella review

Internet-based interventions (IBIs) for behavioural health have been prevalent for over two decades, and a growing proportion of individuals with mental health concerns prefer these emerging digital alternatives. However, the effectiveness and acceptability of IBIs for various mental health disorders continue to be subject to scholarly debate. We performed an umbrella review of meta-analyses (MAs), conducting literature searches in PubMed, Web of Science, Embase, Cochrane and Ovid Medline from their inception to 17 January 2023. A total of 87 MAs, reporting on 1683 randomised controlled trials and 295 589 patients, were included. The results indicated that IBIs had a moderate effect on anxiety disorder (standardised mean difference (SMD)=0.53, 95% CI 0.44 to 0.62) and post-traumatic stress disorder (PTSD) (SMD=0.63, 95% CI 0.38 to 0.89). In contrast, the efficacy on depression (SMD=0.45, 95% CI 0.39 to 0.52), addiction (SMD=0.23, 95% CI 0.16 to 0.31), suicidal ideation (SMD=0.23, 95% CI 0.16 to 0.30), stress (SMD=0.41, 95% CI 0.33 to 0.48) and obsessive-compulsive disorder (SMD=0.47, 95% CI 0.22 to 0.73) was relatively small. However, no significant effects were observed for personality disorders (SMD=0.07, 95% CI -0.13 to 0.26). Our findings suggest a significant association between IBIs and improved mental health outcomes, with particular effectiveness noted in treating anxiety disorders and PTSD. However, it is noteworthy that the effectiveness of IBIs was impacted by high dropout rates during treatment. Furthermore, our results indicated that guided IBIs proved to be more effective than unguided ones, playing a positive role in reducing dropout rates and enhancing patient adherence rates.

Internet-Based Cognitive-Behavioral Therapy for Individuals Experiencing Panic Attacks: A Scoping Literature Review

Panic attacks (PAs) are prevalent and highly comorbid with various physical and psychological disorders. Cognitive-behavioral therapy (CBT) is a well-established psychosocial intervention. Internet-delivered CBT (ICBT) presents a promising avenue to overcome barriers and provide evidence-based support to those in need. The current scoping review aimed to systematically map the existing literature and identify knowledge gaps regarding the impact of ICBT on outcome measures for individuals experiencing PAs. The PRISMA guidelines for scoping reviews were used. A total of 3,044 records were retrieved, and 18 studies from 2013 to 2023 were ultimately included in the analysis. ICBT demonstrated effectiveness as a psychosocial intervention for improving panic symptoms and anxiety in individuals with PAs. However, the impact of ICBT on quality of life (QOL) remains inconclusive. All studies included in this review focused on assessing the severity of panic symptoms, with limited emphasis on measuring QOL. This scoping review holds significant implications for research and practice. However, further addressing the research needs identified in this review will enhance our understanding and improve treatment outcomes for PAs.

Guided versus self-guided internet delivered cognitive behavioural therapy for diagnosed anxiety and related disorders: a preliminary meta-analysis

Guided and self-guided internet-delivered cognitive-behavioural therapy (ICBT) has been demonstrated to be efficacious in the treatment of anxiety and related disorders (ARDs). The aim of the current study was to examine the efficacy of guided and self-guided ICBT for adults diagnosed with ARDs using a meta-analytic synthesis of randomised controlled trials directly comparing the two treatment approaches. Eleven studies (n = 1414) were included. There was a small, but significantly pooled between-group effect size at post-treatment (g = 0.16; 95% CI: 0.03-0.28) favouring guided ICBT. At follow-up, the between-group effect size was small and non-significant (g = 0.13; 95% CI: -0.04-0.30). Gender distribution moderated outcome at post-treatment (higher proportions of females resulted in a smaller between-group effect size). Type of support provided in the guided-treatment arm moderated treatment outcome at follow-up (those receiving synchronous support had a larger between-group effect size). Amount of guidance in the guided-treatment arm moderated effect sizes at post-treatment and follow-up (more guidance leading to larger between-group effect sizes). Automated reminders, disorder type, and treatment length did not moderate outcomes. The results suggest that guided and self-guided ICBT interventions result in similar outcomes, however guided interventions may be marginally more effective in the short term.

The Bergen 4-day treatment for panic disorder: adapting to COVID-19 restrictions with a hybrid approach of face-to-face and videoconference modalities

BACKGROUND

The Bergen 4-day treatment (B4DT) is a concentrated exposure-based therapy that has been shown to be effective in the treatment of anxiety disorders. The current study sought to examine the effectiveness of B4DT for panic disorder (PD), when delivered with a combination of face-to-face sessions and videoconferencing.

METHODS

Treatment was delivered to 50 patients from April 2020 to May 2021. Because of regulations during the pandemic, a significant portion of the treatment was conducted via videoconference. The primary outcome measure was the clinician-rated Panic Disorder Severity Scale (PDSS), and secondary measures included patient-rated symptoms of panic disorder, agoraphobia, generalized anxiety, depression, and treatment satisfaction. Changes in symptom levels over time were estimated using multilevel models.

RESULTS

Patients showed a significant reduction in clinician-rated symptoms of panic disorder (Measured by PDSS) from before treatment to post treatment (d = 2.18) and 3-month follow-up (d = 2.01). At three months follow-up 62% of patients were classified as in remission, while 70% reported a clinically significant response. We also found a reduction in symptoms of depression and generalized anxiety, and the patients reported high satisfaction with the treatment.

CONCLUSION

The current study suggests that B4DT delivered in a combination of videoconference and face-to-face meetings may be a useful treatment approach. As the study is uncontrolled, future studies should also include more strictly designed investigations.

Implementing a revised online screening tool in a routine care online clinic treating anxiety and depression

Introduction

The ItFits implementation toolkit was developed as part of the ImpleMentAll EU Project, to help guide implementation processes. The ItFits toolkit was tested in the online clinic, Internetpsykiatrien, in the Region of Southern Denmark, where it was employed to optimize screening and intake procedures. We hypothesized that a larger proportion of assessed patients would be referred to treatment. Further, we hypothesized the completion rate and effectiveness would increase, as a result of including a more relevant sample.

Method

Using the ItFits-toolkit, Internetpsykiatrien developed a revised online screening tool. Data on patient flow and symptom questionnaires was extracted from Internetpsykiatrien six months prior to- and six months after implementation of the revised online screening tool.

Results

A total of 1,830 applicants self-referred for treatment during the study period. A significantly lower proportion of patients were referred to treatment after implementation of the revised screening tool (pre-implementation, n = 1,009; post-implementation, n = 821; odds ratio 0.67, 95% CI: 0.51; 0.87). The number of patients that completed treatment increased significantly (pre-implementation: 136/275 [49.45%], post-implementation, n = 102/162 [62.96%]; odds ratio 1.79, 95% CI 1.20; 2.70). The treatment effect was unchanged (B = 0.01, p = .996). Worth noting, the number of patients that canceled their appointment for the video assessment interview decreased drastically.

Conclusion

By using the ItFits toolkit for a focused and structured implementation effort, the clinic was able to improve the completion rate, which is an important effect in iCBT. However, contrary to our hypotheses, we did not find an increase in clinical effect, nor a larger ratio being referred to treatment after assessment. The decreased number of referrals for treatment could be a result of increased awareness of inclusion criteria among the clinicians.

CBT-Intervention for panic disorder in primary care: 5 years follow-up of a cRCT during the Covid-19 pandemic

A practice team-based exercise programme with elements of cognitive behavioural therapy (CBT) and case management for patients with panic disorder with or without agoraphobia in primary care showed significant positive effects. Here, we analyse the long-term effects (>5 years) of this intervention in the stressful context of the Covid-19 pandemic. All participants of the original PARADIES cluster randomized controlled trial (cRCT; 2012-2016) were invited to participate in a follow-up during the Covid-19 pandemic. Clinical outcomes were anxiety symptoms, number and severity of panic attacks, agoraphobic avoidance behaviour, Covid-specific anxiety symptom severity, depression, and patient assessment of chronic illness care. Data were analysed cross-sectionally for group differences (intervention, control) and longitudinally (T0: baseline, T1: 6 months and TCorona: >60 months). Of the original 419 participants, 100 participated in the 60 months follow-up (October 2020-May 2021). In the cross-sectional analysis, the anxiety symptom severity in the intervention group was lower than in the control group (p = .011, Cohen's d = .517). In the longitudinal analysis, both groups showed an increase of anxiety and depression symptoms compared to pre-pandemic level. The intervention may have had a lasting impact regarding anxiety severity despite the challenging context of the Covid-19 pandemic. However, we cannot say to what extend the intervention still played a role in participants' lives; other factors may also have helped with coping. The increase of anxiety and depression symptoms in both groups over time could be attributed to external circumstances.

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.

A meta-analytic review of randomized clinical trials of online treatments for anxiety: Inclusion/exclusion criteria, uptake, adherence, dropout, and clinical outcomes

Over the last decade there has been rapid growth in the number of clinical trials examining internet-delivered interventions for anxiety. While there have been numerous analyses of treatment efficacy, few studies have examined treatment engagement. The current meta-analysis examined participant eligibility, uptake, adherence, and drop-out in clinical trials of internet-delivered treatments for anxiety. This meta-analysis used random effects models to obtain estimates of participant inclusion, uptake, adherence, drop-out, and within-group treatment effect size. Moderator analyses examined the effects of anxiety disorder type, treatment type, and level of clinician guidance. After screening, 140 trials with 199 treatment arms (N = 11,021) were included. An average of 46% (95% CI 42, 50) of interested people were included in the clinical trials. In the active treatment arms, 98% (95% CI 97, 99) of participants began treatment, 81% (95% CI 78, 85) of the assigned treatments were completed, 21% (95% CI 18, 23) of individuals dropped out at post-treatment based on questionnaire non-completion, and an overall within-group effect size of g = 1.03 (95% CI 0.94, 1.13) was obtained. Several moderators of interest were significant (e.g., clinical guidance, anxiety disorder type), and there was substantial heterogeneity in estimates. In conclusion, a large number of inclusion and exclusion criteria have been used in trials of internet-delivered treatments for anxiety. Once recruited into a trial, however, most people appear to begin, adhere, and complete internet-delivered treatment for anxiety. Further research exploring various eligibility criteria and their impact on engagement and efficacy is warranted.

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.

Psychosocial treatment for panic disorder: An umbrella review of systematic reviews and meta-analyses

BACKGROUND

Panic disorder is a common and disabling psychiatric condition marked by sudden onset of physiological sensations that are appraised as dangerous. A number of studies and reviews have examined the efficacy of psychosocial treatments for PD; however, there is a lack of overarching reports that discuss the strength of evidence for the different psychosocial treatments for PD. This umbrella review provides an overview of systematic reviews and meta-analyses on psychosocial treatments for PD.

METHODS

A systematic search and review of the literature was conducted according to PRISMA guidelines.

RESULTS

A total of 38 reviews (31 meta-analyses and 7 systematic reviews) were included in the umbrella review. Most of the 38 reviews were focused on the use of CBT, both in-person and internet-based, to treat PD among adults, generally finding it to be an efficacious treatment compared to control conditions. A limited number of the 38 reviews included other age ranges or examined other forms of psychosocial treatments. The methodological quality of most included reviews was rated as critically low according to the AMSTAR-2 rating system.

CONCLUSIONS

Future reviews should focus on improving their methodological quality. Although the included reviews supported CBT as an efficacious treatment for reducing panic symptoms among adults, future research could focus on how CBT compares to other psychosocial treatments and the efficacy of CBT for PD among other populations (e.g., children and adolescents) and among diverse cultural groups.

How technology can enhance treatment: A scoping review of clinical interventions for anxiety and obsessive-compulsive spectrum disorders

OBJECTIVES

Researchers are increasingly investigating how technology could be used to improve the efficacy of treatment for anxiety and obsessive-compulsive (OC) spectrum disorders. A broad range of technologies, disorders and therapeutic processes have been examined in the literature. This review summarizes the evidence for using technology in clinical interventions for anxiety and OC-spectrum disorders and highlights research gaps that should be addressed to improve the evidence base.

METHODS

A scoping review was conducted based on systematic searches of three databases. Broadly, the criteria included interventions that had integrated technology into clinical contexts to enhance treatment for anxiety and OC-spectrum disorders. All records were double-screened by two reviewers, and data were extracted on the characteristics of interventions, symptom outcomes, and implementation factors.

RESULTS

Searches returned 2,475 studies, of which 117 were eligible for inclusion in this review. Although almost all studies reported pre-post-symptom reductions, only one quarter of the controlled studies demonstrated additive effect of technology-based interventions in between-group analyses. We noted a trend in underreporting implementation factors.

CONCLUSIONS

Technology-based interventions can improve the efficacy of treatment for anxiety and OC-spectrum disorders, but there are challenges to achieving this goal. Based on a review of the included studies, we provide four specific recommendations to improve the quality and likelihood of success of future research projects.

PRACTITIONER POINTS

Technology-based adjuvants are unlikely to improve the efficacy of treatment for anxiety or OC-spectrum disorders based on their novelty or convenience alone. A subset of studies gives hope that specific innovations can improve treatment when targeting a therapeutic process that has been problematic. Clinicians seeking to improve the efficacy of their treatment should first define client-specific therapeutic factors (e.g., homework compliance) that could be leveraged, then apply a specific innovation to address this factor.

An Internet Based Intervention for Adults With Autism Spectrum Disorder-A Qualitative Study of Participants Experiences

Background: Adults with autism spectrum disorder face several barriers to accessing evidence-based care, including difficulties in communicating needs, social anxiety or in traveling to a health care unit. In recent years, several forms of internet-based treatments have shown to be effective for a variety of psychiatric conditions. Internet-based treatment alternatives allow convenient and flexible formats, and therefore have the potential to increase access to health care for individuals with autism spectrum disorder. However, knowledge about how internet-based treatment features may suit the needs of individuals with autism is limited. The aim of this study was to explore the participant experiences of an internet-based intervention for adults with autism spectrum disorder. The primary focus of the investigation was on autism-specific needs in relation to the features unique to the online format. Methods: In this qualitative study, semi-structured telephone interviews were conducted with 14 participants who had completed a text-based internet-based intervention for adults with autism spectrum disorder. We used an inductive approach and analyzed the data using qualitative content analysis. Results: Five main categories were identified: (1) implications of the online format, (2) the fixed non-individualized model, (3) therapist interaction, (4) interacting with other participants, and (5) making use of the treatment content. Overall, participants appreciated the availability and that they could work on their treatment independent of time or location. Among those participating in group-based chat-sessions with the other participants, it was considered a generally positive experience. Furthermore, most participants felt safe and relaxed in relation to the therapist and appreciated the text-based format. However, several participants felt that the format and content of the treatment was not sufficiently adapted to their individual life situation. Conclusion: In conclusion, this internet-based treatment constitutes an accessible and energy-saving treatment alternative for adults with autism. Further, integrating group-based components seems feasible in an otherwise individual internet-based treatment for individuals with autism. However, group-based components do require a clear purpose and rationale. Future studies should develop and evaluate treatment adaptations tailored to individual needs.

Cognitive-Behavioral Treatments for Anxiety and Stress-Related Disorders

Cognitive-behavioral therapy (CBT) is a first-line, empirically supported intervention for anxiety disorders. CBT refers to a family of techniques that are designed to target maladaptive thoughts and behaviors that maintain anxiety over time. Several individual CBT protocols have been developed for individual presentations of anxiety. The article describes common and unique components of CBT interventions for the treatment of patients with anxiety and related disorders (i.e., panic disorder, social anxiety disorder, generalized anxiety disorder, obsessive-compulsive disorder, posttraumatic stress disorder, prolonged grief). Recent strategies for enhancing the efficacy of CBT protocols are highlighted as well.

Disorder-specific internet-based cognitive-behavioral therapy in treating panic disorder, comorbid symptoms and improving quality of life: A meta-analytic evaluation of randomized controlled trials

Compared to conventional face-to-face psychological treatments, internet-based cognitive-behavioral therapy (iCBT) presents an innovative alternative that has been found to be effective in the treatment of anxiety disorders. The current study provides a meta-analysis investigating the efficacy of disorder-specific guided self-help (Gsh) iCBT compared to various active and inactive control conditions, with focus on adult panic disorder sufferers with or without agoraphobia (PD/A). Systematic literature search yielded 13 randomized controlled trials (RCTs) (N = 1214) that met the eligibility criteria for this study. We found no statistically significant differences between Gsh iCBT and various active CBT interventions in reducing PD/A symptoms at both post-test (g = 0.015, k = 10) and follow-up (g = 0.113, k = 6) levels. Also, comorbid anxiety and depression were reduced equivalently at post-test (g = 0.004, k = 6) and follow-up (g = 0.004, k = 6). Quality of life was equally improved at post-test (g = -0.100, k = 5) and follow-up (g = 0.074, k = 2). When compared to inactive controls, we found large effect sizes in PD/A (g = -0.892, k = 9) and comorbid anxiety and depression (g = -0.723, k = 9) symptoms, and moderate change in quality of life (g = -0.484, k = 3) at post-test. There was no difference between Guided self-help iCBT and Self-help iCBT in PD/A (g = -0.025, k = 3) and comorbid anxiety and depression (g = -0.025, k = 3) at post-test. Baseline severity, country of original research and adherence to the treatment in form of initial uptake were identified as statistically significant moderators of the iCBT treatment.

Remote cognitive behavioral therapy for panic disorder: A meta-analysis

Cognitive behavioral therapy (CBT) is an established treatment for panic disorder (PD). Remote CBT (RCBT) is becoming increasingly popular and has the potential to enhance access to this treatment. The aim of this study was to examine the efficacy of RCBT for PD using a meta-analytic approach. An electronic database search was used to identify relevant articles and the references of previously completed reviews. Twenty-one studies (n = 1,604; mean age range: 31.9-43.9; mean female representation = 71 %) were included in the meta-analysis. 14/21 (67 %; n = 817 of the included studies were randomised controlled trials and 7/21 (33 %; n = 787) were open trials or non-randomised controlled trials. Pooled within-group effect sizes across all remote treatments for PD symptoms were large from pre-treatment to post-treatment (Hedges' g = 1.18; 95 % CI: 0.99-1.36) and pre-treatment to follow-up (Hedges' g = 1.51; 95 % CI: 1.22-1.79). Pooled between-group findings indicate that remote CBT treatments are more effective than passive control (Hedges' g = 1.17; 95 % CI: 0.85-1.50), but are similar to other active treatments on measures of PD symptoms (e.g., face-to-face CBT) (Hedges' g = 0.02; 95 % CI: -0.43 to 0.48). Internet-delivered CBT (Hedges' g = 1.10, 95 % CI: 0.91-1.30), videoconferencing-delivered CBT (Hedges' g = 1.40, 95 % CI: 0.85-1.95) and bibliotherapy-delivered CBT (Hedges' g = 1.51, 95 % CI: 0.95-2.06) each produce large effect sizes on measures of PD symptoms. The results have important implications for the dissemination of entirely remote stepped-care treatments for PD.

Internet-delivered exposure therapy versus internet-delivered cognitive behavioral therapy for panic disorder: A pilot randomized controlled trial

AIM

To compare the efficacy and acceptability of internet-delivered exposure therapy for panic disorder, to multi-component internet-delivered cognitive behavioral therapy (iCBT) that included controlled breathing, cognitive restructuring and exposure.

METHODS

Participants with panic disorder, with or without agoraphobia, were randomized to internet-delivered exposure therapy (n = 35) or iCBT (n = 34). Both programs were clinician guided, with six lessons delivered over eight weeks. Outcomes included panic disorder and agoraphobia symptom severity, as well as depression symptom severity, functional impairment and days out of role.

RESULTS

Participants in both conditions displayed a large reduction in panic disorder symptom severity (ds >1.30) from pre- to post-treatment. Participants in both conditions displayed medium to large reduction in agoraphobia and depression symptom severity, functional impairment and days out of role. Effects were maintained at three- and six-month follow-up. There was no significant difference between the interventions in clinical outcomes, adherence or treatment satisfaction.

CONCLUSIONS

Internet-delivered exposure therapy appeared to be as acceptable and efficacious as more established iCBT, despite including less strategies. However, a fully powered replication is now needed to compare the two approaches.

Evidence Synthesis of Digital Interventions to Mitigate the Negative Impact of the COVID-19 Pandemic on Public Mental Health: Rapid Meta-review

Background

Accumulating evidence suggests the COVID-19 pandemic has negative effects on public mental health. Digital interventions that have been developed and evaluated in recent years may be used to mitigate the negative consequences of the pandemic. However, evidence-based recommendations on the use of existing telemedicine and internet-based (eHealth) and app-based mobile health (mHealth) interventions are lacking.

Objective

The aim of this study was to investigate the theoretical and empirical base, user perspective, safety, effectiveness, and cost-effectiveness of digital interventions related to public mental health provision (ie, mental health promotion, prevention, and treatment of mental disorders) that may help to reduce the consequences of the COVID-19 pandemic.

Methods

A rapid meta-review was conducted. The MEDLINE, PsycINFO, and CENTRAL databases were searched on May 11, 2020. Study inclusion criteria were broad and considered systematic reviews and meta-analyses that investigated digital tools for health promotion, prevention, or treatment of mental health conditions and determinants likely affected by the COVID-19 pandemic.

Results

Overall, 815 peer-reviewed systematic reviews and meta-analyses were identified, of which 83 met the inclusion criteria. Our findings suggest that there is good evidence on the usability, safety, acceptance/satisfaction, and effectiveness of eHealth interventions. Evidence on mHealth apps is promising, especially if social components (eg, blended care) and strategies to promote adherence are incorporated. Although most digital interventions focus on the prevention or treatment of mental disorders, there is some evidence on mental health promotion. However, evidence on process quality, cost-effectiveness, and long-term effects is very limited.

Conclusions

There is evidence that digital interventions are particularly suited to mitigating psychosocial consequences at the population level. In times of physical distancing, quarantine, and restrictions on social contacts, decision makers should develop digital strategies for continued mental health care and invest time and efforts in the development and implementation of mental health promotion and prevention programs.

Patient alliance with the program predicts treatment outcomes whereas alliance with the therapist predicts adherence in internet-based therapy for panic disorder

This study examines relationships among different aspects of therapeutic alliance with treatment outcome, adherence and attrition in internet delivered cognitive behavioral therapy (ICBT) for panic disorder.

We examined alliance-outcome relationships in ICBT (N = 74) using a newly developed self-report alliance measure that disentangles alliance with program content (Internet Patient's Experience of Attunement and Responsiveness with the program; I-PEARp) and with the therapist (I-PEARt). We compared ICBT outcomes of patient rated and therapist-rated alliance with conventional alliance scales (WAI-6 and WAI-T).

Consistent with our hypothesis, I-PEARp and I-PEARt distinguished between different aspects of the alliance and predicted outcomes better than standard alliance scales. Furthermore, higher ratings of I-PEARp were associated with subsequent lower symptoms and lower symptoms were associated with higher subsequent alliance. In contrast, I-PEARt predicted adherence, but not symptoms. Although therapists' ratings of alliance (thI-PEAR) improved significantly during treatment, they did not predict subsequent symptoms, adherence, or dropout.

Results indicate that the patient experience of the alliance in ICBT includes two aspects, each of which uniquely contributes to outcomes; patient connection to the program is related to symptom outcomes whereas the dyadic relationship with the therapist serves as the glue to allow the treatment to hold.

Intensive one-week internet-delivered cognitive behavioral therapy for panic disorder and agoraphobia: A pilot study

This is the first pilot study to explore the feasibility, acceptability and preliminary efficacy of intensive cognitive behavioral therapy (CBT) for panic disorder and/or agoraphobia delivered via the internet. Ten participants who met DSM-5 criteria for panic disorder and/or agoraphobia (6 males; mean age = 43.40, SD = 15.25) completed The Intensive Panic Program: a six-lesson exposure-based CBT program, delivered online over seven days. Clinician support was provided via phone and email. All 10 participants completed the program (100% adherence) and high levels of satisfaction were reported. We found large and significant reductions in panic symptom severity at post-treatment (d = 1.40), which were maintained at two-month follow-up. We also found large reductions in agoraphobic avoidance (d = 0.92) and functional impairment (d = 1.04) at follow-up, and days out of role were halved. On average, 132 min (SD = 42, range: 47-183) of clinician time was spent per participant during the treatment week. The results provide promising preliminary evidence for the feasibility and acceptability of internet-delivered intensive CBT for panic disorder and/or agoraphobia. A larger, randomized control trial is now needed to evaluate the efficacy of this program compared to a control group and to explore long-term outcomes. Clinical trial registration number ACTRN12618001501235.
