Abstract
This paper describes the results of a pilot Randomized Controlled Trial (RCT) on the effects of a mobile prototype delivering an Ecological Momentary Intervention (EMI) for social anxiety disorder (SAnD). 55 participants were randomized into two groups 1) a standalone EMI based on exposure therapy or 2) a waitlist control group. After excluding people who formally withdrew, 49 participants were analyzed. SAnD symptoms and other related outcomes, including download and EMI usage were collected at baseline and post-test. Four participants from the EMI group (15%) and 10 participants from the control group (38%) completed the post-test assessments. Of the four EMI completers, only two downloaded the mobile app. Results showed no significant improvements in SAnD symptoms or other related mental health outcomes relative to the control group (ESs range). There were no significant differences in help-seeking behaviors between groups at post-test. The results suggest increased human-support, or interactive features may be needed to improve engagement and adherence to EMI, and a subsequent study with a larger sample size may be needed to demonstrate differential effects.
