The aim of this study was to investigate the effect of cognitive?behavioral group therapy (CBGT) on social anxiety disorder using latent growth model (LGM) to estimate average growth trajectories and individual differences in longitudinal treatment outcomes. LGM is able to deal with missing data using full-information maximum-likelihood (FIML) estimation. We analyzed piecewise latent growth for nonlinear growth functions to examine changes during treatment and post-treatment. Our CBGT involved Korean culture-specific variations in classical CBGT during weekly 2-hour sessions over the course of 8 weeks. We assessed 36 patients with social anxiety disorder using Liebowitz Social Anxiety Scale and a brief version of the Fear of Negative Evaluation Scale on five occasions (baseline, 4 weeks, 8 weeks, 4-week follow up, and 8-week follow up). As expected, social anxiety and avoidance decreased significantly during treatment periods. Fear of negative evaluation decreased significantly both during treatment and post-treatment. We could delicately explain individual differences in treatment effect with LGM. This study demonstrated the efficacy of CBGT for social anxiety disorder and the feasibility of using LGM to analyze repeated measures of data on clinical treatment, and longitudinal studies examining treatment effect could use LGM in the future.
