title: The Index of Drug Involvement: a partial validation.
abstract: Social workers often need a wider range of assessment scales that can be used in education, research, and practice. The Index of Drug Involvement (IDI) is a short-form assessment scale that may be of use to social work educators, researchers, and practitioners who work with clients with drug abuse or chemical dependency problems. This article describes the IDI; provides information about its administration, scoring, and interpretation; and describes the initial research conducted to validate the instrument. This article provides information about the reliability of the IDI; reports the standard error of measurement; and presents findings concerning the content, construct, and criterion validity of the instrument. Also presented is initial information about the development and use of a clinical cutting score that will help practitioners evaluate the clinical significance of a drug abuse problem and that can be a guide for establishing initial and final treatment goals.
