Note. Ordinary least squares (OLS) regressions of outcome variables on treatment status. Outcome variables are listed on the left. Nonbinary outcomes are normalized to be mean 0, 1 SD, in the control group, with the exception of the exponential discount factor. Column (1) reports the variable mean for the control group. Column (2) reports the coefficient from an OLS regression of the outcome variable on treatment status, controlling for the baseline measure of the outcome when available, but without adjusting for attrition. Column (3) reports the same coefficient estimated using inverse probability weighting (IPW) to adjust for attrition. Standard errors are reported in parentheses and are clustered at the endline session level. GQ-6 = Gratitude Questionnaire Six-Item Form; SWLS = Satisfaction with Life Scale; PANAS = Positive and Negative Affect Schedule; CES-D = Center for Epidemiologic Studies Depression Scale.
