A nationwide sample of 490 black and white opioid addicts were interviewed 6 and 12 years after entering federally funded treatment programs. A longitudinal classification procedure was developed based on multiple outcomes over the first 4 years after termination from treatment and compared to empirically weighted cross-sectional composite measures in predicting 12-year outcomes. Results indicated that the longitudinal classification scheme satisfactorily predicted subsequent behavioral outcomes and that it also provided valuable descriptive information on global patterns of change over time.
