SSIs for Mental Health and Loneliness

Depression Clinical Trial

Official title: Brief Internet Interventions to Support Mental Health

Status Completed

Clinical Trial Summary

This project includes three studies that explore the effectiveness of brief internet interventions for mental health and loneliness. Study 1: The goal of this clinical trial is to examine if a brief online single-session intervention (SSI) adapted from an evidence-based internet cognitive behavioral therapy can reduce feelings of loneliness in people aged 16 and older who struggle with loneliness. The main question it aims to answer is if a brief SSI is sufficient to meaningfully reduce loneliness compared to an active control. Researchers will test these questions by comparing change in loneliness after 8 weeks between participants randomly assigned to either 1) a 30-minute online SSI for loneliness or 2) a 3-session online intervention for loneliness or 3) an active control SSI. Study 2: The goal of this clinical trial is to examine if an SSI for psychological distress that uses popular online content as its primary form of intervention content can reduce feelings of psychological distress in people aged 16 and older who struggle with psychological distress. The main questions it aims to answer are 1) if curated popular online content can be more effective in supporting people struggling with psychological distress than researcher-created content and 2) if curated popular online content can be more effective in supporting people struggling with psychological distress than un-curated self-selected popular online content. Researchers will test these questions by comparing change in distress after 8 weeks between participants randomly assigned to either 1) 25-minute popular online content-based SSI for distress or 2) an effective 25-minute online SSI for distress with evidence-based researcher-created content or 3) online help-seeking as usual. Study 3: The goal of this clinical trial is to examine if an SSI for loneliness that uses popular online content as its primary form of intervention content can reduce feelings of loneliness in people aged 16 and older who struggle with loneliness. The main questions it aims to answer are 1) if curated popular online content can be more effective in supporting people struggling with loneliness than researcher-created content, 2) if curated popular online content can be more effective in supporting people struggling with psychological distress than an active control, and 3) replicating the comparison in study 1, if a brief SSI is sufficient to meaningfully reduce loneliness compared to an active control. The study will test these questions by comparing change in loneliness after 8 weeks between participants randomly assigned to either 1) a 25-minute popular online content-based SSI for loneliness or 2) a 25-minute online SSI for loneliness with evidence-based researcher-created content or 3) an active control SSI.

Clinical Trial Description

Study 1: Severe loneliness is globally prevalent and is strongly associated with impaired mental and physical well-being, making it a significant public health issue. Evidence-based interventions for loneliness reach a small subset of people who might benefit from them, so identifying new strategies for addressing loneliness at scale should be a high priority. Online single-session interventions (SSIs) have demonstrated particular promise to offer efficient and highly-scalable support to diverse populations. The study will test if an internet-mediated self-guided SSI can produce lasting improvements in loneliness. The investigators adapted a 9-week online loneliness intervention into a 3-week 3-session version and a single-session 30-minute SSI version. The investigators will randomly assign participants to complete the 3-week version, the SSI version, or a control SSI. The investigators will collect self-report measures at baseline, directly after the intervention, and 4 and 8 weeks after baseline. The investigators will also measure participant engagement with the intervention using self-report and behavioral measures. The investigators will recruit teens and adults (16+) for the study via social media. Study 2: SSIs for mental health have shown promise for delivering efficient support to diverse populations. Despite their brevity, existing SSIs still struggle to engage users. This study will explore using a broad range of mental health-relevant popular online content (eg, psychology lectures on YouTube, Instagram posts from self-care influencers, and blog posts written by people who struggle with mood disorders) in SSIs. Although it is often not evidence-based, popular online content may be more appealing and tailored to particular audiences than the researcher-created intervention content typically used in evidence-based SSIs. In this study, researchers will examine the effectiveness of this content for addressing psychological distress. Researchers will conduct an experiment to compare a popular online content-based SSI to one that has already demonstrated efficacy and to online help seeking as usual to identify whether such content is useful within an SSI context. Researchers will measure change in psychological distress from baseline to 4-week and 8-week follow-ups. Study 3: In this study, researchers aim to replicate and extend studies 1 and 2 to further evaluate the potential of an SSI for loneliness and the utility of popular online content as a mental health intervention. In this study, researchers will examine the effectiveness of popular online content for addressing loneliness. Researchers will conduct an experiment to compare a popular online content-based SSI for loneliness to another online SSI for loneliness with researcher-created content and to an active control SSI. Researchers will measure change in loneliness from baseline to 4-week and 8-week follow-ups. ;
