As presented in Table 5, there were significant differences in the association between friend support and alcohol use across developmental stages for AAs. Specifically, friend support was significantly associated with lower alcohol use in emerging adulthood (B = −.28, CI [−.48, −.08], SE = .12, β = −.14, p = .023) and middle adulthood (B = −.59, CI [−.83, −.35], SE = .15, β = −.24, p < .001), but not in young adulthood (B = −.05, CI [−.22, .13], SE = .11, β = −.02, p = .667). These associations significantly differed between young adults and middle-aged adults (χ2 = 7.97, df = 1, p = .005), but there were no statistically significant difference in the associations between emerging adults and young adults (χ2 = 2.03, df = 1, p = .154) or between emerging adults and middle-aged adults (χ2 = 2.57, df = 1, p = .109).
