Mean-level changes in impulsivity, neuroticism, extraversion, and problematic alcohol involvement are shown in Figure 3. Zero-order correlations among the personality constructs of impulsivity, neuroticism, and extraversion with problematic alcohol involvement, marital status, parental status, biological sex, and FH are presented in Table 1. Zero-order correlations among impulsivity, neuroticism, and extraversion are presented in Table 2. Zero-order correlations among problematic alcohol involvement, marital status, parental status, biological sex, and FH are presented in Table 3. Participants who reported abstaining from alcohol across all assessments (n = 6) were excluded from all analyses. LGMs were used to examine the respective changes in impulsivity, neuroticism, extraversion, and problematic alcohol involvement. LGMs were estimated using the statistical package Mplus Version 5 (Muthén & Muthén, 2007). Unless noted otherwise, maximum likelihood estimation with robust standard errors (Satorra & Bentler, 1994) was employed for the LGMs. To allow for analysis of data containing missing values, all LGMs were estimated using full information maximum likelihood (FIML),2 which assumes that data are missing at random.
