Conditional process analysis was used to investigate the conditional indirect effect of 5-HTTLPR on alcohol outcomes through SRE-5, conditioned on parental monitoring and controlling for drinks before SRE-5, sex, age at SRE-5 assessment, and BMI. This model was tested separately for each of the four alcohol outcomes. 5-HTTLPR was a significant predictor of SRE-5 (a = 0.31, p = 0.014), indicating that the LS/SS genotypes were associated with higher SRE-5 scores. This effect was not mediated or moderated and is thus the same for all models. See Fig. 2 for a statistical diagram of the models and Table 3 for model statistics.
