“…The Drug Use Screening Inventory (DUSI) (Tarter, 1990, Tarter and Hegedus, 1991, Tarter et al, 1992) is designed to screen for alcohol or drug use and problems among teenagers and has demonstrated good reliability, discriminate validity, and sensitivity and has published normative cutoff scores (Kirisci et al, 1995, Kirisci et al, 1994, Tarter et al, 1994, Tarter et al, 1997, Tarter et al, 1992, Tarter et al, 1995). A total score combines all 15 items from the substance use scale (assessing the degree of involvement and severity of consequences from alcohol and drug use), three alcohol or drug items on the school performance adjustment scale, and one additional aggression item assessing the clinically predictive problem of breaking things or getting into fights while under the influence of alcohol or drugs (Shaffer et al, 1996).…”
