Multigroup analysis across age groups was also conducted for the model examining moderating roles of social support. Wald test of constraining the four paths linking interaction terms (i.e., alc-GPS ~ family/friend support, and sensation seeking ~ family/friend support) to alcohol use to equal across age groups was not statistically significant (χ2 = 15.02, df = 8, p = .06), suggesting no differences in the moderating role of social support for the associations between alc-GPS, sensation seeking, and alcohol use across age groups (supplemental Table 8).
