Descriptive statistics across age groups are presented in supplemental Table 6. Multigroup analysis across age groups was conducted for the path model examining sensation seeking and social support as indirect pathways linking alc-GPS to alcohol use. Wald test of constraining all paths linking alc-GPS, sensation seeking, social support, and alcohol use to be equal across age groups (emerging vs. young vs. middle adulthood) was statistically significant (χ2 = 30.89, df = 14, p = .006), indicating age differences in the associations between alc-GPS, sensation seeking, social support, and alcohol use. Follow up analysis testing the paths one by one across age groups indicated that the association between family support and alcohol use significantly varied across age groups (χ2 = 7.81, df = 2, p = .020); higher family support was associated with lower alcohol use among emerging (B = −3.97, SE = 1.49, β = −.19, p = .008) and middle adults (B = −2.78, SE = 1.00, β = −.10, p = .005), but not among young adults (B = .71, SE = 1.18, β = .02, p =
