Grades 9-12. This program includes 20 questionnaires and the scoring manual. It is a research-based, 52-item assessment tool measures adolescents' behaviors and attitudes related to drug use. The HIT - D&A requires only a fourth-grade reading level and can be completed by adolescents in 5 to 10 minutes. It provides information on the type and degree of drug use, impact of drugs on the adolescent's life, normative levels of soft and hard drug use, abuse and dependence symptoms, and how adolescents rationalize the use of drugs through self-serving cognitive distortions such as self-centered, blaming others, minimizing/mislabeling, and assuming the worst. The questionnaire, which includes scoring and computation instructions and forms, is useful in assessment, treatment planning, tracking therapeutic progress, and individual- or program-level outcome evaluation.
