Overview
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.
Description
Depression and anxiety are prevalent mental health conditions that are frequently under-treated. To improve timely and effective psychological treatment, Internet-delivered Cognitive Behaviour Therapy (ICBT) has been developed as a scalable treatment option. ICBT delivers evidence-based therapeutic content via structured online lessons over the course of several months, teaching the same skills as face-to-face cognitive behaviour therapy. In routine practice, ICBT is typically accompanied by brief therapist guidance offered via secure messaging and/or phone calls.
In Saskatchewan, the Online Therapy Unit (OTU) offers ICBT as part of routine care for a range of mental health concerns. The flagship program is the Wellbeing Course, a transdiagnostic ICBT program targeting symptoms of depression and anxiety. Research shows this course is associated with substantial significant improvements in depression and anxiety that are maintained over time. Nevertheless, not all clients engage with or respond equally to treatment. Consequently, there is a need to explore enhancements to ICBT that may improve outcomes for clients receiving care in naturalistic settings.
Emerging research shows a strong association between depression, anxiety and loneliness. Consistent with these findings, OTU recently found that approximately 76% of past OTU clients who enrolled in the Wellbeing Course reported experiencing frequent loneliness. Notably, ICBT was found to reduce loneliness in addition to alleviating symptoms of depression and anxiety.
Previous studies have found that many OTU clients engage with supplementary resources provided alongside the Wellbeing Course to tailor the program to their individual needs. However, no research to date has examined whether individuals experiencing frequent loneliness derive added benefit from receiving targeted content addressing loneliness in the context of ICBT for depression and anxiety.
The present trial aims to address this gap by evaluating whether offering additional loneliness content alongside the Wellbeing Course leads to greater engagement, satisfaction and improved treatment outcomes among clients with frequent loneliness compared to those who complete the Wellbeing Course alone.
The study is a partially randomized controlled trial conducted within a naturalistic online ICBT clinic. Clients seeking treatment who met the eligibility criteria and reported elevated levels of loneliness (i.e., ≥ 6 on the UCLA loneliness scale) are considered for inclusion in the study. Due to practical constraints related to therapist workload and the volume of referrals, not all eligible clients will be enrolled. To manage this, a subset of eligible clients are randomly assigned to one of two study conditions: (1) the Wellbeing Course or (2) the Wellbeing Course plus a Loneliness Resource. Other eligible clients are assigned to receive the standard Wellbeing Course outside of the study protocol, depending on service capacity at the time of intake. These non-study clients are not included in the study analyses. This approach allowed for the evaluation of the loneliness resource while maintaining routine clinical operations and equitable service access. Therapist support will be offered alongside the Course to all eligible clients for 8 weeks, with the possibility of extended support (when requested and clinically indicated) up to 12 weeks. Moreover, a booster session will be offered 12 weeks after the start of treatment to help clients review their progress and explore techniques that can assist in addressing any difficulties they may encounter in maintaining their well-being. All clients who take part in the Wellbeing Course will be asked to complete primary outcome questionnaires at screening and weeks 4, 8, and 20. Primary outcomes will be loneliness, depression and anxiety.
