“…These associations are consistent across: (1) cross-sectional designs (Forster, Grigsby, Unger, & Sussman, 2015; Pokhrel, Sussman, Sun, Kniazev, & Masagutov, 2010; Sussman, McCuller & Dent, 2003) and prospective designs predicting future drug use from previous SSC (Pokhrel, Sussman, Rohrbach, & Sun, 2007; Pokhrel et al, 2013; Pokhrel, Sussman, & Stacy, 2014); (2) various settings spanning alternative (continuation) high schools (Pokhrel, Sussman, Rohrbach, & Sun, 2007; Pokhrel, Sussman, & Stacy, 2014; Sussman, McCuller & Dent, 2003), traditional high schools (Pokhrel, Sussman, Rohrbach, & Sun, 2007; Pokhrel et al, 2010; Pokhrel et al, 2013), and middle schools (Forster, Grigsby, Unger, & Sussman, 2015); and (3) several demographic strata, including predominately Mexican-American youth samples (Pokhrel et al, 2013), Russian youths (Pokhrel, Sussman, Sun, Kniazev, & Masagutov, 2010), and a relatively large percentage of African American youth samples (41% of the sample; Forster, Grigsby, Unger, & Sussman, 2015). These studies provide evidence of concurrent and predictive validity for the SSCS.…”
