We present simple effects of treatment among participants who did and did not, respectively, report recent intimate partner violence (IPV) at baseline. We then present the interaction between treatment and baseline IPV, from a separate regression in which effects of treatment and baseline IPV were included. For each effect, we present the coefficient for each dependent measure, the 95% confidence interval for the coefficient based on robust standard errors, the p value for the coefficient, and the number of observations for each dependent measure. For dependent measures that are standardized indices corresponding to a family of related survey measures, we analyze the index components using seemingly unrelated regression (SUR) and conduct a Wald test of the significance of the interaction term coefficient within the system of equations; the p value for this joint test of significance is presented in the final column. We control for baseline assessment of dependent measures, socioeconomic status, life stage, and project site. Numeric ranges in parentheses refer to the response scale of dependent measure; y/n indicates a binary yes/no response scale
