Instrumentation for the Measurement of Inmates' Drug Use, Knowledge, and Attitudes

Abstract

A methodology was devised for the construction of instruments to measure inmates' drug use, knowledge, and attitudes. A drug use inventory and a drug attitude scale were examined for construct validity, whereas a drug knowledge test was examined for content validity. In regard to reliability, each measurement tool was subjected to item analysis for internal consistency. Investigators obtained necessary data from 150 inmates at two county correctional institutions. Factors considered during instrumentation were subjects' reading and comprehension levels, drug experiences, and willingness to participate in data collection. Implications and suggestions are discussed concerning the use of such instruments in inmate drug education.
