“…Validity of the scales has been demonstrated in several ways, including statistically significant convergent and discriminant validity with other behavior rating scales (Emerson, Crowley, & Merrell, 1994;Merrell, 1993b); evidence of strong sensitivity to theoretically based group differences (Merrell, 1992(Merrell, , 1993bMerrell & Gill, 1994; Merrell, Sanders, & Popinga, 1993;Robbins & Merrell, 1998); convergence with other types of assessment such as sociometric procedures, self-report instruments, and direct behavioral observation (Merrell, 1993b;Merrell, Cedeno, & Johnson, 1993); and strong classification accuracy of students from various special education and clinical groups (Merrell, 1992(Merrell, , 1993bMerrell, Sanders, & Popinga, 1993). Additionally, a parent report version of the SSBS, the Home and Community Social Behavior Scales, was recently developed (Merrell, 2002).…”
