Peer reviewedAnglin, M. Douglas; And Others – Evaluation Review, 1993
Reliability and validity of self-reported behavior within a deviant population are examined using data from 2 interviews with 323 narcotics addicts conducted 10 years apart (1974-75 and 1985-86). Results complement existing reliability and validity studies of alcohol use, and suggest that quality information can be obtained from heroin users. (SLD)
