Building Closer Friendships in social anxiety disorder: A randomized control trial of an internet-based intervention.

Background And Objectives: Loneliness is an important factor in mental and physical health. People with social anxiety disorder (SAD) often report high levels of loneliness, which may be maintained by difficulties with intimacy. Building Closer Friendships (BCF) is a technology-based intervention we developed to reduce loneliness through reducing fear of intimacy in individuals with SAD.

Methods: A sample of individuals with current SAD (N = 55), were randomized to BCF or waitlist control conditions and completed self-report assessments of loneliness, fear of intimacy, social anxiety and other outcomes throughout the study. An in vivo conversation task was also administered at post-treatment to assess distress and perceived disclosure, warmth, and friendliness of participants when interacting with a stranger.

Results: In the intent-to-treat analyses, the BCF group reported lower fear of intimacy at post-treatment compared to the control group. Among completers, BCF led to lower fear of intimacy at post-treatment and follow-up, and lower loneliness and depression at follow-up compared to the waitlist control. No treatment effects were found in the conversation task or for other symptom outcomes, including social anxiety. Analyses of treatment components revealed that the frequency of emotional check-ins with friends was associated with reductions in loneliness and depression.

Limitations: The study was limited by the sample of primarily undergraduate college students, and use of self-report measures.

Conclusions: This preliminary study found modest support for BCF as a computerized intervention to reduce fear of intimacy and loneliness in individuals with SAD.
