Enhancing Internet-Delivered Cognitive Behaviour Therapy With Additional Content

Summary

This study evaluates the effectiveness of additional content on loneliness offered alongside the Wellbeing Course - an internet-delivered cognitive behavioral therapy (ICBT) intervention for symptoms of depression and anxiety- in improving treatment outcomes for individuals with elevated scores on loneliness seeking treatment for depression and anxiety at a routine care online therapy clinic (the Online Therapy Unit). In this partially randomized control trial, the investigators aim to contribute to the literature by examining whether providing additional content on loneliness alongside the Wellbeing Course enhances engagement, satisfaction, and treatment outcomes among clients experiencing frequent loneliness compared to those completing only the Wellbeing Course. Over 8 weeks, participants will review course materials (with the addition of the loneliness content for those assigned to the loneliness content condition) online and complete questionnaires assessing changes in various outcomes over time.

Interventions

BEHAVIORAL

Internet-delivered cognitive behavioral therapy

The Wellbeing Course was developed at Macquarie University, Australia. The Wellbeing Course is a transdiagnostic Internet-delivered cognitive behavioural intervention targeting symptoms of depressive and anxiety disorders. It comprises 5 online lessons targeting: 1) symptom identification and the cognitive behavioural model; 2) thought monitoring and challenging; 3) de-arousal strategies and pleasant activity scheduling; 4) graduated exposure; and 5) relapse prevention. Materials are presented in a didactic (i.e., text-based with visual images) and case-enhanced learning format (i.e., educational stories demonstrate the application of skills) and include homework activities. Lessons are released gradually in a standardized order over 8 weeks. Phone calls will only be made if there is a significant clinical issue requiring therapist attention that cannot be addressed over email (e.g., sudden increase in symptoms). Therapists will spend \~15 mins per week/per client.

BEHAVIORAL

Additional Loneliness Content

The additional Loneliness Content was developed at the Online Therapy Unit, University of Regina, Canada. Relevant sections of the resource will be included at the end of each lesson within the Wellbeing Course. The Loneliness Content provides psychoeducation and skills for loneliness using a cognitive behavioral framework. Consistent with the Wellbeing Course content, the Loneliness Content will target 1) identification of loneliness; 2) loneliness thought monitoring and challenging; 3) de-arousal strategies and pleasant activity scheduling for loneliness; 4) behaviours (conversation skills); and 5) relapse prevention.
