Local average treatment effect on clinical HIV and mental and behavioral health outcomes
REGRESSION
IV regression was conducted to compare clinical outcomes between intervention participants who disclosed HIV status post-intervention and those who did not. There were no significant differences in CD4 count, PHQ-9 scores, or SDQ scores between the children of intervention compliers and non-compliers at 6 months, 12 months, 18 months, or 24 months post-intervention (Effect of intervention and disclosure on mental and psychosocial outcomes up to 24 months post-intervention.OLS regression was also conducted for comparison using the predetermined subset of non-disclosed caregiver-child dyads at baseline. There were also no significant differences in CD4 count, PHQ-9 scores, or SDQ scores between those who completed the intervention vs. those who were in the control group at any point post-intervention. All When comparing OLS and IV methodology, a clinically significant difference between models was defined as a 5-fold difference in the test statistic, or the difference in outcomes between intervention participation (OLS methodology) and disclosure (IV methodology). IV analysis found a clinically significant decrease in SDQ scores at 6 months (0.031 vs. −1.524, 49.2-fold difference) and 12 months (−0.042 vs. −0.348, 8.3-fold difference) as compared to OLS analysis, indicating improved behavioral health over the 1
