Figure 2. Sibling Facilitation of Adolescent Alcohol use: Path Analysis Results (N= 580).

Standardized coefficients are shown for each path Significance is denoted by ** p < .01, * p < .05. For ease of presentation, standardized coefficients are not shown for correlations among independent variables that are non-significant from zero and all non-significant paths are dashed. Proportion of variance explained (R²) are shown for all dependent variables. In total, results suggest that the association between elder and younger sibling alcohol use was completely mediated by perceived sibling facilitation of alcohol use, and the association between perceived elder sibling use and younger sibling alcohol use was partially mediated by this variable. Fit statistics and indirect effect sizes are reported in text.
