- Note: CPT Cognitive Processing Therapy, IS individual support, SD standard deviation, SE standard error. aUnadjusted mean scores. bβ is the coefficient for the interaction between treatment group (CPT or IS) and assessment time point and represents the difference in the change in felt stigma over time between women in the CPT and IS arms. Estimated using longitudinal mixed-effect linear regression; random effects included participant, CPT group, and village. Model covariates were baseline age, marital status (currently married yes or no), language, having lived in the current village for at least 10 years or less, total number of people living in the household, number of types of traumas experienced and witnessed, average baseline functioning score, and average baseline score on all mental health symptom items not included on the felt stigma scale. cCohen’s D effect size standardized using the pooled baseline standard deviation of the felt stigma outcome. dP-value is for the Wilcoxon rank-sum test of difference in felt stigma mean score at baseline by treatment group
