Abstract
OBJECTIVE Exposure with response prevention (ERP) is the first-line treatment for obsessive-compulsive disorder (OCD). However, refusals, dropouts and the required high time and logistic effort constitute barriers to the use of ERP. In a non-inferiority randomized controlled trial, we compared metacognitive therapy (MCT) to exposure with response prevention (ERP) as treatments for OCD. METHOD 74 outpatients received 12 weekly sessions of either manualized MCT or ERP, with primary outcomes assessed by blinded assessors using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at pre-treatment, mid-treatment, post-treatment, and 6-month follow-up. Secondary outcomes included measures of depression and anxiety. Non-inferiority margin was specified at no less than d = 0.38 below the improvement reached by ERP, corresponding to a difference of about 3 points on the Y-BOCS. RESULTS Drop-out rates were low (<14%) and similar in both groups. Linear models indicated non-inferiority of MCT to ERP at post-treatment, but not at 6-month follow-up. While both groups showed comparable Y-BOCS improvements, the MCT group demonstrated a significantly greater reduction in state anxiety scores at post-treatment and follow-up. CONCLUSIONS Overall, MCT was not inferior to ERP, especially at post-treatment, suggesting it could be a treatment alternative. However, further research is needed to explore differential treatment indications.

Abstract
Obsessive-compulsive disorder (OCD) is a common mental health condition characterized by distressing, intrusive thoughts (obsessions) and repetitive behaviours (compulsions) aimed at reducing anxiety. Internet-based cognitive behavioural therapy (ICBT) has emerged as an effective treatment modality for various mental health disorders. This meta-analysis evaluates the efficacy of guided self-help ICBT (GSH ICBT) and unguided self-help ICBT (SH ICBT) against active and passive control conditions in adults with OCD. A comprehensive systematic literature search yielded 12 randomized controlled trials (RCTs) comprising 15 comparison arms (N = 1416) that met the inclusion criteria. Results indicate that GSH ICBT significantly reduced OCD symptomatology posttreatment compared to active controls (g = 0.378, k = 9), with no significant effects maintained at follow-up (g = 0.153, k = 4). GSH ICBT was also found to be as effective as active CBT interventions in reducing comorbid anxiety and depression symptoms posttreatment (g = 0.278, k = 6) and at follow-up (g = 0.124, k = 4). However, improvements in quality of life were not significant posttreatment (g = 0.115, k = 4) nor at follow-up (g = 0.179, k = 3). Combined GSH and SH ICBT demonstrated large effects on reducing OCD symptoms (g = 0.754, k = 6), medium effects on comorbid symptoms (g = 0.547, k = 6) and small effects on quality of life (g = 0.227, k = 2) when compared to inactive controls. No significant differences were found between GSH and SH ICBT in all measured outcomes posttreatment (OCD: g = 0.098, k = 3; AD: g = 0.070, k = 3; QoL: g = -0.030, k = 1) and at follow-up (OCD: g = 0.265, k = 2; AD: g = 0.084, k = 2; QoL: g = 0.00, k = 1). Sample size was identified as a significant moderator of treatment effects. This paper further explores clinical significance, treatment adherence, therapist time investment and moderator influences of the ICBT. The limitations of the study and recommendations for future research are thoroughly discussed.

Abstract
INTRODUCTION Expert consensus operationalized treatment response and remission in obsessive-compulsive disorder (OCD) as a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) reduction ≥35% and score ≤12 with ≤2 on Clinical Global Impressions Improvement (CGI-I) and Severity (CGI-S) scales, respectively. However, there has been scant empirical evidence supporting these definitions. METHODS We conducted a systematic review and an individual participant data meta-analysis of randomized-controlled trials (RCTs) in adults with OCD to determine optimal Y-BOCS thresholds for response and remission. We estimated pooled sensitivity/specificity for each percent reduction threshold (response) or posttreatment score (remission) to determine response and remission defined by a CGI-I and CGI-S ≤ 2, respectively. RESULTS Individual participant data from 25 of 94 eligible RCTs (1235 participants) were included. The optimal threshold for response was ≥30% Y-BOCS reduction and for remission was ≤15 posttreatment Y-BOCS. However, differences in sensitivity and specificity between the optimal and nearby thresholds for response and remission were small with some uncertainty demonstrated by the confidence ellipses. CONCLUSION While the empirically derived Y-BOCS thresholds in our meta-analysis differ from expert consensus, given the predominance of data from more recent trials of OCD, which involved more refractory participants and novel treatment modalities as opposed to first-line therapies, we recommend the continued use of the consensus definitions.

Abstract
BACKGROUND Cognitive behavioural therapy (CBT) has been shown to be effective for several psychiatric and somatic conditions; however, most randomized controlled trials (RCTs) have administered treatment in person and whether remote delivery is similarly effective remains uncertain. We sought to compare the effectiveness of therapist-guided remote CBT and in-person CBT. METHODS We systematically searched MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials from inception to July 4, 2023, for RCTs that enrolled adults (aged ≥ 18 yr) presenting with any clinical condition and that randomized participants to either therapist-guided remote CBT (e.g., teleconference, videoconference) or in-person CBT. Paired reviewers assessed risk of bias and extracted data independently and in duplicate. We performed random-effects model meta-analyses to pool patient-important primary outcomes across eligible RCTs as standardized mean differences (SMDs). We used Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidance to assess the certainty of evidence and used the Instrument to Assess the Credibility of Effect Modification Analyses (ICEMAN) to rate the credibility of subgroup effects. RESULTS We included 54 RCTs that enrolled a total of 5463 patients. Seventeen studies focused on treatment of anxiety and related disorders, 14 on depressive symptoms, 7 on insomnia, 6 on chronic pain or fatigue syndromes, 5 on body image or eating disorders, 3 on tinnitus, 1 on alcohol use disorder, and 1 on mood and anxiety disorders. Moderate-certainty evidence showed little to no difference in the effectiveness of therapist-guided remote and in-person CBT on primary outcomes (SMD -0.02, 95% confidence interval -0.12 to 0.07). INTERPRETATION Moderate-certainty evidence showed little to no difference in the effectiveness of in-person and therapist-guided remote CBT across a range of mental health and somatic disorders, suggesting potential for the use of therapist-guided remote CBT to facilitate greater access to evidence-based care.

Abstract
Cognitive-behavioural therapy is an effective treatment for obsessive-compulsive disorder (OCD). However, there are many barriers in accessing this treatment, with stigma being a particularly prominent barrier for many patients. Self-guided internet-delivered cognitive-behavioural therapy (ICBT), which does not require any contact with a therapist, has the potential to overcome this barrier. However, there is limited research on the efficacy of self-guided ICBT for OCD. The aim of the current study was to examine the efficacy of self-guided ICBT for OCD in a large international sample. Two hundred and sixteen participants were included in the study (Mage = 34.00; SD = 12.57; 72.7% female). On the primary outcome measure, the Yale-Brown Obsessive-Compulsive Scale (YBOCS), a medium within-group effect size was found from pre-treatment to post-treatment (g = 0.63), and a large within-group effect size was found from pre-treatment to 3-month follow-up (g = 0.98). Approximately one-quarter to one-third of participants met criteria for clinically significant improvement at post-treatment and 3-month follow-up (11% and 17% met criteria for remission at post-treatment and 3-month follow-up, respectively). These results demonstrate that self-guided ICBT may be an efficacious treatment for individuals with OCD who cannot or do not wish to engage with a mental health professional, resulting in medium to large effect sizes.

Abstract
This study investigated the long-term effectiveness and cost-effectiveness of guided internet-based cognitive behavioral therapy (ICBT) for obsessive-compulsive disorder (OCD). Twenty-five patients with OCD who had undergone guided ICBT in a randomized controlled trial or a single-arm trial were followed up for 6, 12, and 24 months. Missing data were imputed using the mice package in R, and a one-way analysis of variance with repeated measures was performed. The total Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score significantly decreased from baseline to all endpoints (p < 0.001). OCD remission (the total Y-BOCS score < 14) rates significantly increased from post-treatment (48 %) at the 12 months (80 %) and 24 months (76 %) follow-up (χ2 (1) = 7.11-11.08, p < 0.01) post guided ICBT. Regression analysis predicted the maintenance of remission at 12 and 24 months following post-treatment remission (z = 2.20, p = 0.03). An incremental cost-effectiveness ratio was calculated to assess the cost-effectiveness of guided ICBT. The incremental cost-effectiveness ratio was JPY 999,495, below the JPY 5 million threshold for willingness to pay in Japan. Our findings demonstrate the long-term effectiveness and cost-effectiveness of guided ICBT for OCD. Guided ICBT can mitigate the severity of OCD even after treatment.

Abstract
CLINICAL QUESTION What is the comparative effectiveness of available therapies for chronic pain associated with temporomandibular disorders (TMD)? CURRENT PRACTICE TMD are the second most common musculoskeletal chronic pain disorder after low back pain, affecting 6-9% of adults globally. TMD are associated with pain affecting the jaw and associated structures and may present with headaches, earache, clicking, popping, or crackling sounds in the temporomandibular joint, and impaired mandibular function. Current clinical practice guidelines are largely consensus-based and provide inconsistent recommendations. RECOMMENDATIONS For patients living with chronic pain (≥3 months) associated with TMD, and compared with placebo or sham procedures, the guideline panel issued: (1) strong recommendations in favour of cognitive behavioural therapy (CBT) with or without biofeedback or relaxation therapy, therapist-assisted mobilisation, manual trigger point therapy, supervised postural exercise, supervised jaw exercise and stretching with or without manual trigger point therapy, and usual care (such as home exercises, stretching, reassurance, and education); (2) conditional recommendations in favour of manipulation, supervised jaw exercise with mobilisation, CBT with non-steroidal anti-inflammatory drugs (NSAIDS), manipulation with postural exercise, and acupuncture; (3) conditional recommendations against reversible occlusal splints (alone or in combination with other interventions), arthrocentesis (alone or in combination with other interventions), cartilage supplement with or without hyaluronic acid injection, low level laser therapy (alone or in combination with other interventions), transcutaneous electrical nerve stimulation, gabapentin, botulinum toxin injection, hyaluronic acid injection, relaxation therapy, trigger point injection, acetaminophen (with or without muscle relaxants or NSAIDS), topical capsaicin, biofeedback, corticosteroid injection (with or without NSAIDS), benzodiazepines, and β blockers; and (4) strong recommendations against irreversible oral splints, discectomy, and NSAIDS with opioids. HOW THIS GUIDELINE WAS CREATED An international guideline development panel including patients, clinicians with content expertise, and methodologists produced these recommendations in adherence with standards for trustworthy guidelines using the GRADE approach. The MAGIC Evidence Ecosystem Foundation (MAGIC) provided methodological support. The panel approached the formulation of recommendations from the perspective of patients, rather than a population or health system perspective. THE EVIDENCE Recommendations are informed by a linked systematic review and network meta-analysis summarising the current body of evidence for benefits and harms of conservative, pharmacologic, and invasive interventions for chronic pain secondary to TMD. UNDERSTANDING THE RECOMMENDATION These recommendations apply to patients living with chronic pain (≥3 months duration) associated with TMD as a group of conditions, and do not apply to the management of acute TMD pain. When considering management options, clinicians and patients should first consider strongly recommended interventions, then those conditionally recommended in favour, then conditionally against. In doing so, shared decision making is essential to ensure patients make choices that reflect their values and preference, availability of interventions, and what they may have already tried. Further research is warranted and may alter recommendations in the future.

Abstract
INTRODUCTION Individual cognitive behavioural therapy (CBT) with exposure and response prevention is an effective treatment for obsessive-compulsive disorder (OCD). However, individual CBT is costly and time-consuming, requiring weekly therapy sessions for 3-4 months. A 4-day intensive version of CBT for OCD delivered in group format has been recently developed in Norway (Bergen 4-day treatment, B4DT). B4DT has shown promising results in several uncontrolled and one small, randomised trial, but its non-inferiority to the gold standard treatment has not been established. METHODS AND ANALYSIS This single-blind, randomised controlled trial including 120 patients (60 per arm) will compare B4DT to individual CBT. The primary outcome is the blind assessor-rated Yale-Brown Obsessive Compulsive Scale (Y-BOCS). We hypothesise that B4DT will be non-inferior to gold standard CBT 15 weeks after treatment start. The non-inferiority margin is set at four points on the Y-BOCS. Secondary outcomes include time to treatment response, cost-effectiveness, response and remission rates, drop-out rates and adverse events. ETHICS AND DISSEMINATION This study has been approved by the Swedish Ethical Review Authority. Hypotheses were specified and analysis code published before data collection started. Results from all analyses will be reported in accordance with the Consolidated Standards of Reporting Trials statement for non-pharmacological trials and Consolidated Health Economic Evaluation Reporting Standards irrespective of outcome. TRIAL REGISTRATION NUMBER NCT05608278.

Abstract
Cognitive behavioral therapy (CBT) is widely recognized as an effective treatment for obsessive-compulsive disorder (OCD). However, few patients are able to receive CBT. Internet-based CBT (ICBT) may be able to overcome this problem. In this study, we aimed to compare the efficacy of CBT, therapist-guided ICBT (TG-ICBT), unguided ICBT (UG-ICBT), and none therapist-guided ICBT (NTG-ICBT) by a network meta-analysis. The primary outcome was the mean change in OCD severity measured by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) or the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). The secondary outcomes included the severity of depressive symptoms, side effects, and cost-effectiveness. A total of 25 trials with 1642 participants were included. We found that the efficacy of CBT was superior to that of TG-ICBT. The mean improvement in Y-BOCS/CY-BOCS scores was higher in CBT group than in UG-ICBT group, but this difference was not statistically significant. The efficacy did not differ significantly between TG-ICBT and UG-ICBT. CBT, TG-ICBT, and UG-ICBT were all more effective than the psychological placebo, waiting list, and pill placebo. In terms of efficacy, CBT combined with drug therapy was better than CBT, TG-ICBT, and UG-ICBT. Sensitivity analyses supported these findings. Based on the current evidence, we recommend TG-ICBT when CBT is not available. However, it is undeniable that UG-ICBT also has the potential to be an effective alternative to CBT. More evidence is needed to support this possibility.

Abstract
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.

Abstract
Approximately one-fifth of new parents struggle with unwanted intrusive thoughts (UITs) about intentionally harming their child. This study evaluated the initial efficacy, feasibility and acceptability of a novel online self-guided cognitive intervention for new parents with distressing UITs. Self-recruited parents (N = 43, 93% female, age 23-43 years) of children 0-3 years reporting daily distressing and impairing UITs were randomized to the 8-week self-guided online cognitive intervention or to waiting-list. The primary outcome was change on the Parental Thoughts and Behaviour Checklist (PTBC) from baseline to week 8 (post-intervention). The PTBC and negative appraisals (mediator) were assessed at baseline, weekly, post-intervention and at the 1-month follow-up. Results showed that the intervention led to statistically significant reductions in distress and impairment associated with UITs at post-intervention (controlled between-group d = 0.99, 95% CI 0.56 to 1.43), which were maintained at the 1-month follow-up (controlled between-group d = 0.90, 95% CI 0.41 to 1.39). The intervention was deemed to be feasible and acceptable by the participants. Change in negative appraisals mediated reductions in UITs but the model was sensitive to mediator-outcome confounders. We conclude that this novel online self-guided cognitive intervention can potentially reduce the distress and impairment associated with UITs in new parents. Large-scale trials are warranted.Abbreviations: UITs: Unwanted Intrusive Thoughts PTBC: Parental Thoughts and Behaviour Checklist.

Abstract
BACKGROUND Demand for adolescent mental health services has surged in the aftermath of the COVID-19 pandemic, and traditional models of care entailing in-person services with licensed mental health providers are inadequate to meet demand. However, research has shown that with proper training and supervision mentors can work with youth with mental health challenges like depression and anxiety and can even support the use of evidence-based strategies like cognitive behavioral therapy (CBT). In our increasingly connected world, youth mentors can meet with young people on a web-based platform at their convenience, reducing barriers to care. Moreover, the internet has made evidence-based CBT skills for addressing depression and anxiety more accessible than ever. As such, when trained and supervised by licensed clinicians, mentors are an untapped resource to support youth with mental health challenges. OBJECTIVE The objective of this study was to develop and assess the feasibility and acceptability of Appa Health (Appa), an evidence-based mental health mentoring program for youth experiencing symptoms of depression and anxiety. This paper describes the development, pilot testing process, and preliminary quantitative and qualitative outcomes of Appa's 12-week smartphone app program which combines web-based near-peer mentorship with short-form TikTok-style videos teaching CBT skills created by licensed mental health professionals who are also social media influencers. METHODS The development and testing processes were executed through collaboration with key stakeholders, including young people and clinical and research advisory boards. In the pilot study, young people were assessed for symptoms of depression or anxiety using standard self-report clinical measures: the Patient Health Questionnaire-8 and the Generalized Anxiety Disorder-7 scales. Teenagers endorsing symptoms of depression or anxiety (n=14) were paired with a mentor (n=10) based on preferred characteristics such as gender, race or ethnicity, and lesbian, gay, bisexual, transgender, queer (LGBTQ) status. Quantitative survey data about the teenagers' characteristics, mental health, and feasibility and acceptability were combined with qualitative data assessing youth perspectives on the program, their mentors, and the CBT content. RESULTS Participants reported finding Appa helpful, with 100% (n=14) of teenagers expressing that they felt better after the 12-week program. Over 85% (n=12) said they would strongly recommend the program to a friend. The teenagers were engaged, video chatting with mentors consistently over the 12 weeks. Metrics of anxiety and depressive symptoms reduced consistently from week 1 to week 12, supporting qualitative data suggesting that mentoring combined with CBT strategies has the potential to positively impact youth mental health and warrants further study. CONCLUSIONS Appa Health is a novel smartphone app aiming to improve the well-being of youth and reduce anxiety and depressive symptoms through web-based mentoring and engaging CBT video content. This formative research sets the stage for a large-scale randomized controlled trial recently funded by the National Institutes of Health Small Business Innovation Research program.

Abstract
Internet-based cognitive-behavioural interventions (iCBT) are a valuable alternative to face-to-face psychotherapy. An unguided iCBT program has shown to be efficacious for patients with obsessive-compulsive disorder (OCD). However, the modules' mode of action is not well understood, which is the objective of the present study. Twenty-five patients with OCD who participated at the iCBT program for 8 weeks answered a questionnaire on their self-efficacy, motivation, expected increase in health competence and experiential avoidance before and after each module and were included in the present analyses. Linear mixed-effects models demonstrated that patients' expected increase in health competence improved over the course of the treatment. No within-module-specific effect was found. The iCBT program was able to improve patients' expected health competence. However, all other variables did not change. The iCBT program should be revised by focusing more strongly on the integration of the content to reduce experiential avoidance and to improve motivation.

Abstract
BACKGROUND Adherence to internet-based cognitive-behavioral therapy (iCBT) is often low, possibly reducing its potential. The current study set out to test whether adherence and effects of unguided iCBT for obsessive-compulsive disorder (OCD) could be improved by varying the degree of autonomy in which modules are completed (free choice vs. fixed order). METHODS We randomized 151 individuals with OCD to either an unguided iCBT with a fixed (iCBTfixed) or a free-choice (iCBTfree+) order of the modules. We assessed participants at baseline (t0), eight weeks (t1), and 16 weeks (t2). Primary outcomes were adherence (utilization time, modules completed) and change in OCD severity (Y-BOCS). Secondary outcomes included depression, self-esteem, and treatment satisfaction. We calculated intent-to-treat (ITT) and complete case (CC) analyses. RESULTS Analyses showed that both iCBT programs significantly reduced OCD severity. While groups did not differ on the ITT analyses, for the CC analyses, a greater improvement was found in the iCBTfixed in comparison to the iCBTfree+ group regarding OCD severity and quality of life, with medium effect sizes from t0 to t1 (ηp2 = 0.067-0.077). Time of utilization and number of modules completed did not differ between groups. LIMITATIONS No placebo control group, short follow-up period, self-report assessment. CONCLUSIONS iCBT is effective in improving OCD. Despite similar adherence in the fixed versus the free-choice module order, the study offers tentative evidence that a fixed order of content is associated with better effects. More research on the effects of adherence on outcome is necessary.

Online versus in-person delivery of cognitive behaviour therapy for obsessive compulsive disorder: An examination of effectiveness. Clin Psychol Psychother 2023.

Abstract
Cognitive behavioural therapy (CBT) including exposure and response prevention is the first-line psychological treatment for obsessive compulsive disorder (OCD). Given changes in the clinical landscape, there are increasing efforts to evaluate its effectiveness in online contexts. Mirroring the traditional in-person delivery, few studies have assessed the role of therapist-guided, manual-based CBT for OCD delivered in real-time via videoconferencing methods. The present study sought to fill this gap by comparing in-person and online delivery of group-based CBT for the treatment of OCD. A convenience sample of participants with moderate to severe OCD (n = 144) were recruited from a naturalistic database from two large OCD specialty assessment and treatment centres. Patients received group-based CBT that was provided in-person (pre-COVID-19 pandemic; March 2018 to March 2020) or online via videoconferencing (during the COVID-19 pandemic; March 2020 to April 2021). In both delivery methods, treatment consisted of 2-h weekly sessions led by trained clinicians. Analyses revealed that, regardless of treatment modality, both in-person and online groups demonstrated significant, reliable, and statistically equivalent improvements in OCD symptoms post-treatment. Videoconferenced, clinician-led CBT may be a promising alternative to in-person delivery for those with moderate to severe OCD symptoms.

JAMA Dermatol 2023; 159:992-995. [PMID: 37466986 PMCID: PMC10357355 DOI: 10.1001/jamadermatol.2023.2167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 05/17/2023] [Indexed: 07/20/2023]
Abstract
Importance Body-focused repetitive behaviors (BFRBs; eg, skin picking) encompass a set of conditions at the interface of dermatology and psychiatry/psychology. The disorder is prevalent but currently underdiagnosed and undertreated. Objective To compare a new self-help intervention, habit replacement, against a wait-list control condition for the treatment of BFRBs. Design, Setting, and Participants This randomized clinical trial was conducted online in 2022. Participants were a population-based nonclinical sample with BFRBs and were recruited via social media. Initially, 481 individuals entered the assessment; 213 were excluded blind to results. A final sample of 268 participants were randomized. The intervention period was 6 weeks. Interventions Participants were randomized to a self-help intervention, habit replacement, or a wait-list control condition (each n = 134). Main Outcomes and Measures The Generic BFRB Scale-45 (GBS-45, self-report) represented the primary outcome. Results Individuals in the 2 conditions (n = 268; 241 [89.9%] women; mean [SD] age, 36.8 [11.1] years; skin picking, 68.3%; trichotillomania, 28.4%; nail biting, 36.6%; lip-cheek biting, 26.1%; other, 20.1%) did not differ on any baseline characteristics. The experimental group significantly improved on the primary outcome (GBS-45) for both the per-protocol (technique was used at least once weekly, ηp2 = 0.068, P = .001) and the intention-to-treat analyses relative to the wait-list control group (expectation-maximization algorithm; ηp2 = 0.019, P = .02). The interaction of group and time yielded statistical trends in favor of the experimental condition only on the Patient Health Questionnaire-9 and quality of life. For the Clinical Global Impressions scale, more individuals in the habit replacement group reported improvement (52.8% vs 19.6%; P < .001). User satisfaction in the habit replacement group was high. Moderation analyses that included all baseline variables showed that those who exhibited nail biting particularly benefited from the new technique. Conclusions and Relevance The present proof-of-concept randomized clinical trial tentatively demonstrates that habit replacement is a feasible and effective self-help strategy against BFRBs, especially for nail biting. Study limitations include the lack of external assessment and verified diagnoses. In addition, the study is missing follow-up data. Self-help habit replacement shows promise in reducing BFRBs but not concomitant symptoms. Trial Registration German Clinical Trials Register Identifier: DRKS00030511.

Efficacy of an Internet-based intervention with self-applied exposure therapy in virtual reality for people with panic disorder: study protocol for a randomized controlled trial. Trials 2023; 24:521. [PMID: 37573377 PMCID: PMC10422760 DOI: 10.1186/s13063-023-07536-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Accepted: 07/25/2023] [Indexed: 08/14/2023] Open
Abstract
BACKGROUND Due to several treatment barriers, many individuals with panic disorder do not receive evidence-based treatment. One promising option to narrow this treatment gap is Internet-based psychotherapy, which has been shown particularly effective in guided formats. Still, there remains room for improvement to make these digital therapies more accessible, cost-efficient, and aligned with best practices for in-person interventions (e.g., exposure). The smartphone app "Invirto - Treatment for Anxiety" offers digitally guided, evidence-based treatment of panic disorders including virtual reality (VR) for exposure therapy. The aim present study is to investigate the efficacy, safety, and acceptance of Invirto in comparison to a care-as-usual (CAU) control group. METHODS We plan to conduct a randomized controlled trial with two conditions (intervention vs. CAU), three assessment times via online surveys (t0: baseline; t1: 3 months after baseline; t2: follow-up assessment 6 months after baseline), and a total of 128 participants with a clinical diagnosis of panic disorder (symptoms must be experienced ≥ 1 year). Recruitment will take place via email, phone, and the study website. The primary outcome will be the change in anxiety symptoms as measured by Beck's Anxiety Inventory from t0 to t1. Secondary outcomes will be the change in anxiety symptoms (measured by the Panic and Agoraphobia Scale, PAS; Questionnaire on panic-related Anxieties, Cognitions and Avoidance, ACA), depressive symptoms (measured by the Beck-Depression-Inventory, BDI-II), treatment satisfaction (measured by the Client Satisfaction Questionnaire, CSQ-8; Treatment Adherence Perception Questionnaire, TAPQ-adapt; Positive and Negative Effects of Psychotherapy Scale, PANEPS-I), psychological flexibility (measured by the Acceptance and Action Questionnaire-II, AAQ-II), and dissociation during VR exposure (measured by an adapted version of the Peritraumatic Dissociative Experiences Questionnaire, PDEQ-adapt). Participants in the intervention group will receive access to the intervention (Invirto) right after t0, while the CAU group will receive access to Invirto after t1. We expect a larger change in both the primary and secondary outcomes from t0 to t1 in the intervention group in comparison to the CAU group. DISCUSSION This study is one of the first to evaluate an Internet-based intervention for people with panic disorder that includes self-application of VR exposure therapy. The findings are expected to extend the body of knowledge about effective Internet-based treatment options for people with panic disorder. The empirical and clinical implications and the limitations of the study are discussed. TRIAL REGISTRATION DRKS00027585 ( www.drks.de/drks_web/ ), date of registration: 13 January 2022.

Abstract
INTRODUCTION Patients with obsessive-compulsive disorder (OCD) often have limited exposure to a diverse environment and perform repetitive compulsions such as excessive cleaning and washing, which could lead to altered gut microbiome. Therefore, longitudinal studies that investigate changes in gut microbiome before and after cognitive behavioral therapy based on exposure and response prevention (ERP) are warranted. METHODS All study participants (N = 64) underwent a structured psychiatric diagnostic interview prior to inclusion. Nutritional intake was assessed with a comprehensive food frequency questionnaire. Stool samples were collected from OCD patients before ERP (n = 32) and 1 month after completion of ERP (n = 15), as well as from healthy controls (HCs; n = 32). Taxonomic and functional analyses were performed using data from microbiome whole genome sequencing. RESULTS Patients with OCD at baseline reported consuming significantly less fiber than HCs (R2 = .12, F(2, 59) = 5.2, p ≤ .01). There were no significant differences in α- and β-diversity indices, or taxonomic dissimilarities at the species level between patients with OCD and HCs, or within patients before and after ERP. Functional profiling based on gut microbial gene expression was grouped into 56 gut-brain modules with neuroactive potential. None of the gut-brain modules differed significantly in expression between patients with OCD at baseline and HCs or within patients before and after ERP. CONCLUSIONS The diversity, composition, and functional profile of the gut microbiome in patients with OCD did not differ significantly from HCs and remained stable over time, despite behavioral changes.

Abstract
BACKGROUND Obsessive-compulsive disorder (OCD) is a neuropsychiatric condition featuring patterns of obsessions, compulsions, and avoidant behaviors that are often time consuming and distressing to affected individuals. Cognitive-behavioral therapy (CBT) with exposure and response prevention and/or serotonin reuptake inhibitors are first-line treatments for OCD, though other therapeutic interventions may serve as economically practical modalities under various circumstances. Exploring and understanding the cost effectiveness of all indicated OCD interventions are important to inform therapeutic decisions and provide quality patient-centered care at a cost that is not burdensome to the patient and/or healthcare system. METHODS A systematic literature review was performed and studies were extracted from PubMed, Embase, Ovid MEDLINE, and Cochrane. All cost-effectiveness studies that included economic analyses with respect to OCD treatment modalities and were written in English and published between January 2010 and July 2022 were eligible for inclusion in the present study. We report a narrative synthesis of the findings and quality appraisal of the selected references. RESULTS Of the 707 references returned in the literature search, a total of 18 cost-effectiveness studies were included for review. Compared with treatment as usual, several studies reported clinical superiority and cost effectiveness of Internet-based CBT programs for adults and children with OCD at various willingness-to-pay thresholds and economic reference indicators, though cost effectiveness relative to in-person CBT with exposure and response prevention is unclear and estimates of efficacy are likely lower for Internet-based CBT. One study favored the cost utility of serotonin reuptake inhibitor monotherapy over CBT with exposure and response prevention although efficacy estimates of the former tend to be lower, and relative cost differences were low. Five studies evaluated the cost effectiveness of high-intensity neuroaugmentation, including deep brain stimulation and stereotactic radiosurgical capsulotomy, in the context of treatment-refractory OCD. CONCLUSIONS Despite the relatively high prevalence of OCD worldwide, cost-effectiveness data for therapeutic modalities remain sparse. Because of the chronic nature of OCD, the cost of treatment accumulates and may lead to a significant financial burden over time, particularly when non-evidence-based interventions are used. However, several alternative therapeutic modalities hold promise for economic practicality without significant sacrifice in clinical efficacy. Future studies are necessary to directly compare the cost effectiveness of such therapeutic alternatives with the current standard of care, CBT with exposure and response prevention.

Abstract
Objectives Therapist-guided internet-delivered cognitive behaviour therapy (ICBT) is an efficacious treatment for obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD), but it is unclear if the results obtained in controlled trials can be reproduced in clinical settings. We evaluated the implementation of ICBT for OCD (OCD-NET) and BDD (BDD-NET) in the Swedish public health system. Methods Consecutive referrals to an outpatient psychiatric clinic providing ICBT, with a primary diagnosis of OCD or BDD, were included in the study. Four hundred and thirty-four participants started OCD-NET and 163 started BDD-NET. The primary outcome measures were the Yale Brown Obsessive Compulsive Scale (Y-BOCS) and the Y-BOCS for BDD (BDD-YBOCS), respectively. Participants were assessed before treatment, weekly during treatment, and after treatment. The study used the RE-AIM implementation framework, and the elements of reach, effectiveness, adoption, and implementation for the evaluation. Results Intention to treat analysis of the OCD-NET sample (n = 434) showed a significant decrease in OCD symptoms from pre-treatment to post-treatment (mean reduction = -8.77 [95 % CI -9.48 to -8.05] p < .001, d = 1.94 [95 % CI 1.75 to 2.13]). Forty-nine percent (95 % CI 43 % to 56 %) of the participants in OCD-NET were classified as treatment responders and 21 % (95 % CI 16 % to 27 %) were in remission. Participants in BDD-NET (n = 163) also showed a significant decrease in BDD symptoms from pre-post treatment (mean reduction = -11.37 [95 % CI -12.9 to -9.87] p < .001, d = 2.07 [95 % CI 1.74 to 2.40]) and 69 % (95 % CI 58 % to 79 %) of the participants were classified as treatment responders and 48 % (95 % CI 38 % to 58 %) were in full or partial remission. Eighty-seven percent of the participants in OCD-NET and 78 % in BDD-NET were treatment completers and participants in both treatment groups reported a high treatment satisfaction at post treatment (OCD-NET = 87 %, BDD-NET = 79 %). The most reported negative effects attributed to the treatments were transient experiences of unpleasant feelings (52 %) and anxiety (50 %). The implementation also influenced treatment delivery and dramatically decreased the mean number of patients waiting to receive face-to-face treatment at the clinic. Conclusions Our results indicate that OCD-NET and BDD-NET are suitable treatments for implementation in a Swedish public health service.

Abstract
OBJECTIVES To evaluate the cost-effectiveness of internet-delivered cognitive behaviour therapy for body dysmorphic disorder (BDD-NET). DESIGN Secondary cost-effectiveness analysis from a randomised controlled trial on BDD-NET versus online supportive psychotherapy. SETTING Academic medical center. PARTICIPANTS Self-referred adult participants with a primary diagnosis of body dysmorphic disorder and a score of 20 or higher on the modified Yale-Brown Obsessive Compulsive Scale for BDD (n = 94). Patients receiving concurrent psychotropic drug treatment were included if the dose had been stable for at least two months. INTERVENTIONS Participants received either BDD-NET (n = 47) or online supportive psychotherapy (n = 47) for 12 weeks. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome measures were cost-effectiveness and cost-utility from a societal perspective, using remission status from a diagnostic interview and quality-adjusted life years (QALY), respectively. Secondary outcome measures were cost-effectiveness and cost-utility from a health care perspective and the clinic's perspective. RESULTS Compared to supportive psychotherapy, BDD-NET produced one additional remission for an average societal cost of $4132. The cost-utility analysis showed that BDD-NET generated one QALY to an average cost of $14,319 from a societal perspective. CONCLUSIONS BDD-NET is a cost-effective treatment for body dysmorphic disorder, compared to online supportive psychotherapy. The efficacy and cost-effectiveness of BDD-NET should next be directly compared to in-person cognitive behaviour therapy. TRIAL REGISTRATION NCT02010619.

Abstract
In clinical trials of obsessive-compulsive disorder (OCD), clinical outcomes are generally measured using lengthy clinician-administered interviews. However, in routine clinical practice, many clinicians lack the time to administer such instruments. This study evaluated cutoffs for treatment response and remission in OCD using the self-rated Obsessive-Compulsive Inventory-Revised (OCI-R). Data from 349 patients in three clinical trials of cognitive-behavioral therapy for OCD were pooled for analysis. The OCI-R was compared to gold-standard criteria for response and remission based on the clinician-administered Yale-Brown Obsessive Compulsive Scale and the Clinical Global Impression Scale. The results showed that a ≥40% reduction on the OCI-R was the optimal cutoff for treatment response, with a sensitivity of 0.72 and a specificity of 0.79. For remission status, the optimal cutoff was ≤8 points on the OCI-R, with a sensitivity of 0.57 and specificity of 0.83. Results from additional analyses using the 12-item version of the OCI were similar. These cutoffs provide a simple and time-efficient way to help determine treatment response and remission in OCD when the administration of clinician-administered instruments is unfeasible.

Compr Psychiatry 2023; 120:152357. [PMID: 36410261 PMCID: PMC10848818 DOI: 10.1016/j.comppsych.2022.152357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Revised: 08/07/2022] [Accepted: 11/14/2022] [Indexed: 11/17/2022] Open
Abstract
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.

Examining Change in the Frequency of Adaptive Actions as a Mediator of Treatment Outcomes in Internet-Delivered Therapy for Depression and Anxiety. J Clin Med 2022; 11:jcm11206001. [PMID: 36294322 PMCID: PMC9605214 DOI: 10.3390/jcm11206001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 10/07/2022] [Accepted: 10/10/2022] [Indexed: 11/17/2022] Open
Abstract
Adaptive actions, including healthy thinking and meaningful activities, have been associated with emotional wellbeing. The Things You Do Questionnaire—21 item (TYDQ-21) has recently been created to measure the frequency of such actions. A study using the TYDQ-21 found that adaptive actions increased across Internet-delivered therapy for symptoms of depression and anxiety, and higher TYDQ-21 scores were associated with lower psychological distress at post-treatment. The current study examined the relationships between adaptive actions and psychological distress among adults (n = 1114) receiving Internet-delivered therapy as part of routine care in Canada, and explored whether adaptive actions mediated reductions in depression and anxiety. As hypothesised, adaptive actions increased alongside reductions in depression and anxiety symptoms from baseline to post-treatment. Treatment effects were consistent when the intervention was provided with regular weekly therapist support or with optional weekly therapist support, and some (but not all) types of adaptive actions had a mediating effect on change in depressive symptoms. The present findings support further work examining adaptive actions as a mechanism of change in psychotherapy, as well as the utility and scalability of Internet-delivered treatments to target and increase adaptive actions with the aim of improving mental health.
