Note: Iterated principal factor analysis. Values are normalized loadings from promax rotation. Loadings above .30 for ASSIST substance-specific scale items that load onto the respective factor are bolded. Loadings above .30 for ASSIST substance-specific scale items that cross onto another factor are italicized.
