Three separate bivariate growth models, one for each personality construct, were estimated. These models provided good to excellent fit to the data, χ2s(65, N = 483) = 143.74–167.05, ps < .001, CFIs = .94–.95, RMSEAs = .05–.06, SRMRs = .04–.05. As shown in Table 6, the respective intercepts for all three personality constructs (i.e., impulsivity, neuroticism, and extraversion) were positively correlated to the respective intercepts of alcohol involvement. These results indicate that individuals high in initial levels in these personality constructs were also high in initial levels of problematic alcohol involvement.
