There were significant differences in the associations between social support and alcohol use across different developmental stages in adulthood for EAs (Table 4). Specifically, higher family support was associated with lower alcohol use (B = −.14, CI [−.23, −.06], SE = .05, β = −.09, p = .007) for emerging adults (age 18–29), higher alcohol use (B = .13, CI [.04, .22], SE = .05, β = .07, p = .013) for young adults (age 30–44), and was not significantly associated with alcohol use in middle adulthood (age 45–65; B = .03, CI [−.08, .13], SE = .06, β = .02, p = .671) (χ2 = 13.81, df = 2, p = .001). These associations significantly differed between emerging adults and young adults (χ2 = 13.61, df = 1, p < .001), but did not significantly differ between young adults and middle-aged adults (χ2 = 1.62, df = 1, p = .203) or between emerging adults and middle-aged adults (χ2 = 4.31, df = 1, p = .038). The association between friend support and alcohol use also varied across adulthood
