Enhancing Internet-Delivered Cognitive Behaviour Therapy With Additional Content

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.
