A digital iCBT intervention for social anxiety disorder in Quebec and Ontario: protocol for a multi-phase effectiveness-implementation study.

Background: Social anxiety disorder (SAD) is one of the most prevalent anxiety disorders in Canada. Viable therapy options for the treatment of SAD include CBT being delivered virtually. In Australia, an innovative internet-delivered cognitive-behavioral therapy (iCBT) program for social anxiety has been developed, implemented, and demonstrated as effective.

[Professionals' Perceptions Regarding the Implementation of Guided Self-help in the context of the Programme québécois pour les troubles mentaux].

Objective Common mental disorders, such as anxiety and depression, have many individual and societal consequences. Various treatments are available for people with these diagnoses, including medication and cognitive behavioral therapy. When these disorders are mild or moderate, psychotherapy is the recommended first-line treatment, given its greater long-term efficacy than pharmacotherapy.

[Short-term interventions offered by les centres locaux de services communautaires (CLSC) to people living with anxiety or depressive disorders: Results of the longitudinal component of the Shared Knowledge study].

Context In Quebec, adult mental health (AMH) first-line teams are mandated to provide psychosocial services to people living with mental health difficulties, including anxiety and mood disorders. Following the establishment of new clinical guidelines in 2017, the duration of interventions was not to exceed 15 sessions, with some exceptions. Objectives The overall aim of the longitudinal component of the Shared Knowledge study was to evaluate the care experience of individuals with an anxiety or depressive disorder receiving a short-term intervention (<15 sessions) by first-line AMH teams, and the evolution of recovery over time.

The effectiveness of transdiagnostic cognitive behavioural therapy for anxiety disorders: the role of and impact of comorbid depression.

Transdiagnostic Cognitive Behaviour Therapy (tCBT), an intervention designed to be applicable across multiple diagnoses, was introduced to improve limitations in traditional therapy such as cost and access to trained therapists. It has been established as an effective and efficacious treatment for anxiety disorders, though there has been little research focussed on the role of depression. The current study investigated the role of comorbid depression during tCBT for anxiety disorders in primary care settings as an outcome and a moderator of anxiety outcomes.

Cost-Effectiveness of Group Transdiagnostic Cognitive Behavioural Therapy for Anxiety Disorders in Primary Care Settings: Economic Evaluation From the Healthcare System Perspective Over a 1-Year Time Horizon.

Aim: To assess the incremental cost-effectiveness ratio (ICER) of group transdiagnostic cognitive-behavioural therapy (tCBT) added to treatment as usual (TAU) for anxiety disorders compared to TAU only from the healthcare system perspective over a 1-year time horizon.

Methods: Data from a pragmatic multisite randomized controlled trial where adults (18-65 years) with an anxiety disorder were randomized to tCBT + TAU ( = 117) or TAU ( = 114). Group tCBT is a 12-week (2h weekly sessions) community-based intervention.

Moderators of the cost-effectiveness of transdiagnostic CBT for anxiety disorders over an 8-month time horizon using a net-benefit regression framework.

Background: Access to evidence-based psychological treatment is a concern in many parts of the globe due to government-level financial constraints and patient-level barriers. Transdiagnostic cognitive behavioural therapy (tCBT) is an effective treatment approach that uses a single protocol for anxiety disorders which could enhance the dissemination of evidence-based psychotherapy. In a context of limited resources, the study of treatment moderators can allow to identify subgroups for which the cost-effectiveness of an intervention differs, information that could impact decision-making.

An examination of sudden gain prevalence across cognitive-behavioural therapy for anxiety and depressive disorders: A quantitative analysis and meta-analytic review.

Sudden gains, incidences of unexpectedly large and stable session to session symptom reductions during psychotherapy, have been shown in samples of individuals receiving treatment for both anxiety and depressive disorders, although seemingly more frequently in sample receiving treatment for depressive disorders. This may suggest that sudden gains are a function of depression, but the high comorbidity between anxiety and depressive disorders makes this difficult to assess. Study One utilised a sample of 117 adults undergoing CBT for a principal anxiety disorder to explore the effect of comorbid depression on sudden gain prevalence.

An analysis of differential improvement by diagnosis in group transdiagnostic cognitive behaviour therapy for anxiety disorders.

Introduction: Anxiety disorders are the most prevalent among the mental health disorders and have a negative impact on an individual's life. Cognitive behaviour therapy (CBT) is documented as the most effective treatment for anxiety disorders. However, challenges associated with implementing diagnosis-specific CBT have led to transdiagnostic approaches of CBT (tCBT).

Cost-effectiveness of transdiagnostic group cognitive behavioural therapy for anxiety disorders treatment as usual: economic evaluation of a pragmatic randomized controlled trial over an 8-month time horizon using self-reported data.

Background: This economic evaluation supplements a pragmatic randomized controlled trial conducted in community care settings, which showed superior improvement in the symptoms of adults with anxiety disorders who received 12 sessions of transdiagnostic cognitive-behavioural group therapy in addition to treatment as usual (tCBT + TAU) compared to TAU alone.

Methods: This study evaluates the cost-utility and cost-effectiveness of tCBT + TAU over an 8-month time horizon. For the reference case, quality-adjusted life years (QALYs) obtained using the EQ-5D-5L, and the health system perspective were chosen.

[Influence of Comorbidity in Cognitive-Behavioral Treatment of Anxiety and Mood Disorders].

Objectives Anxiety and depression are the most prevalent disorders observed in health care services and are frequently comorbid with other disorders. Although Cognitive-Behavioral Therapy (CBT) has widely been shown efficacious to treat anxiety and mood disorders, studies that have focused on its effectiveness in the presence of comorbidity have been few and show conflicting results. Thus, the implications of the presence of comorbid disorders for treatment are still unknown.

Virtually-delivered Sudarshan Kriya Yoga (SKY) for Canadian veterans with PTSD: A study protocol for a nation-wide effectiveness and implementation evaluation.

Background: Post-traumatic stress disorder (PTSD) remains a significant treatment challenge among Canadian veterans. Currently accessible pharmacological and non-pharmacological interventions for PTSD often do not lead to resolution of PTSD as a categorical diagnosis and have significant non-response rates. Sudarshan Kriya Yoga (SKY), a complementary and integrative health (CIH) intervention, can improve symptoms of PTSD.

Anxiety in bipolar disorder: A review of publication trends.

Background: Although anxiety is highly prevalent in people with bipolar disorders and has deleterious impact on the course of the illness, past reviews have shown that many aspects of the topic remain under-researched. This scoping review aims to provide a comprehensive overview of the literature addressing anxiety in bipolar disorder (A-BD) between 2011 and 2020, assess if the interest in the topic has increased over the period and map the publication trends.

Methods: Three databases were systematically searched, and all articles were screened at the title/abstract and full text level based on inclusion and exclusion criteria.

French adaptation and validation of the Panic Disorder Severity Scale-self-report.

Background: The aims of this study were to conduct a cross-cultural validation of the Panic Disorder Severity Scale - Self-Report (PDSS-SR) and to examine psychometric properties of the French-Canadian version.

Methods: A sample of 256 adults were included in the validation study based on data from the baseline interview of a clinical trial on transdiagnostic cognitive-behavioral therapy for mixed anxiety disorders. Participants completed the Anxiety and Related Disorders Interview Schedule (ADIS-5), and self-report instruments including the PDSS-SR, Beck Anxiety Inventory (BAI), Mobility Inventory for Agoraphobia (MIA), Sheehan Disability Scale (SDS), Patient Health Questionnaire (PHQ-9), Social Phobia Inventory (SPIN), Insomnia Severity Index (ISI) and Penn State Worry Questionnaire (PSWQ).

Which, who and when? Therapeutic processes in group cognitive behaviour therapy for anxiety disorders.

The evidence for the effect of therapeutic alliance in group cognitive behaviour therapy (CBT) for anxiety disorders is unclear. Identifying whether the alliance-outcome relationship depends on (1) which components are assessed, (2) who is measuring the alliance and (3) when the alliance is measured will help to clarify the role of the client-therapist relationship in therapy. The present study explored the effects of alliance component (agreement vs.

Evaluating the quality, safety, and functionality of commonly used smartphone apps for bipolar disorder mood and sleep self-management.

Background: Individuals with bipolar disorder (BD) are increasingly turning to smartphone applications (apps) for health information and self-management support. While reviews have raised concerns regarding the effectiveness and safety of publicly available apps for BD, apps surveyed may not reflect what individuals with BD are using. The present study had two aims: first, to characterize the use of health apps to support mood and sleep amongst people with BD, and second, to evaluate the quality, safety and functionality of the most commonly used self-management apps.

A pragmatic randomized controlled trial of a group self-management support program versus treatment-as-usual for anxiety disorders: study protocol.

Background: The integration of a personal recovery-oriented practice in mental health services is an emerging principle in policy planning. Self-management support (SMS) is an intervention promoting recovery that aims at educating patients on the nature of their mental disorder, improving their strategies to manage their day-to-day symptoms, fostering self-efficacy and empowerment, preventing relapse, and promoting well-being. While SMS is well established for chronic physical conditions, there is a lack of evidence to support the implementation of structured SMS programs for common mental disorders, and particularly for anxiety disorders.

Impact of group transdiagnostic cognitive-behavior therapy for anxiety disorders on comorbid diagnoses: Results from a pragmatic randomized clinical trial in primary care.

Background: Anxiety and depressive disorders are the most common mental illnesses worldwide, with most individuals meeting criteria for more than one diagnosis. Most cognitive-behavioral therapy (CBT) approaches target only one disorder at a time, resulting in the need to treat comorbid diagnoses sequentially. Transdiagnostic CBT protocols have been developed that simultaneously treat principal and comorbid disorders.

[Qualitative Evaluation of the Implementation of Group Psychoeducation for Bipolar Disorder in Clinical Settings in Quebec].

Objectives Bipolar disorder is a chronic condition which significantly impacts the functioning and quality of life of patients with the disorder. Recognized efficacious psychological interventions, such as group psychoeducation, can help better address some of the limitations observed when pharmacotherapy is used alone in the management of bipolar disorder. However, access to these evidence-based interventions seems to be limited for most patients.

[Effectiveness of Behavioral Activation for the Treatment of Severe Depression in Clinical Settings].

Objectives Among interventions that have been shown to be efficacious in the treatment of depression, behavioural activation (AC) is receiving increasing attention as the evidence supporting its effectiveness continues to accumulate. Although the efficacy of AC for the treatment of depression has been established through numerous randomized controlled trials, studies evaluating the effectiveness of AC when implemented in mental health settings are rare and there is insufficient supportive data. This step is, however, essential to the validity and the generalization of the treatment to the reality of clinical settings.

Group transdiagnostic cognitive-behavior therapy for anxiety disorders: a pragmatic randomized clinical trial.

Background: Transdiagnostic group cognitive-behavioral therapy (tCBT) is a delivery model that could help overcome barriers to large-scale implementation of evidence-based psychotherapy for anxiety disorders. The aim of this study was to assess the effectiveness of combining group tCBT with treatment-as-usual (TAU), compared to TAU, for the treatment of anxiety disorders in community-based mental health care.

Methods: In a multicenter single-blind, two-arm pragmatic superiority randomized trial, we recruited participants aged 18-65 who met DSM-5 criteria for principal diagnoses of generalized anxiety disorder, social anxiety disorder, panic disorder, or agoraphobia.

The Quality of Life in Bipolar Disorder (QoL.BD) Scale: Validation of a French Cross-Cultural Adaptation.

Objective: The goal of this study was to validate the French version of the Quality of Life in Bipolar Disorder (QoL.BD) scale, a condition-specific measure for bipolar disorder (BD).

Method: The QoL.

Getting better my way: Feasibility study of a self-management support tool for people with mood and anxiety disorders.

Objective: Self-management support is recognized as an important component of the management of mood and anxiety disorders. The goal of this feasibility study was to evaluate the acceptability, implementation and perceived usefulness of a new comprehensive self-management tool () in four care settings in Quebec, Canada.

Method: Care providers offered the tool to people with difficulties related to mood or anxiety disorders during a 7-month period.

A pragmatic randomized controlled trial of group transdiagnostic cognitive-behaviour therapy for anxiety disorders in primary care: study protocol.

Background: Anxiety disorders are the most common mental disorders in community settings, and they are associated with significant psychological distress, functional and social impairment. While cognitive behaviour therapy (CBT) is the most consistently efficacious psychological treatment for anxiety disorders, barriers preclude widespread implementation of CBT in primary care. Transdiagnostic group CBT (tCBT) focuses on cognitive and behavioural processes and intervention strategies common to different anxiety disorders, and could be a promising alternative to conventional CBT.

Secondary outcomes of the guided self-help behavioral activation and physical activity for depression trial.

This article presents secondary outcome variables from a randomized controlled trial evaluating the efficacy of two guided self-help interventions for the treatment of depression: behavioral activation (BA) and physical activity (PA). Both interventions resulted in significant reductions in depressive symptoms compared to the wait-list control group, however the mechanisms by which these interventions influenced depression were not presented. The purpose of this paper was to compare changes in secondary outcome variables to gain insight into the mechanisms by which reactivation interventions reduce depressive symptoms.

Efficacy of guided self-help behavioural activation and physical activity for depression: a randomized controlled trial.

Behavioural activation and physical activity have received empirical support that highlight their efficacy in reducing depression. Even though both behavioural activation and physical activity share the common goal of reactivating the individual, limited research has directly compared these interventions, and more research is required to evaluate their efficacy when offered in low-intensity formats. The present study involves a randomized controlled clinical trial comparing the efficacy of two guided self-help interventions for the treatment of depression: behavioural activation and physical activity.
