Abstract: The present study apphed a quasi-experimental design to examine whether methadone mainte nance treatment demonstrates cumulative (i.e., rehabilitative) or stabilizing effects on behavior of narcotics addicts over multiple treatment episodes. Nearly 1,000 addicts in Southern Califor nia methadone maintenance clinics were interviewed to obtain retrospective self-report infor mation on their addiction histories. Nine measures, including use of narcotics and other drugs, crime involvement, and employment, were analyzed using repeated measures analysis of vari ance. The observed patterns of behavioral changes clearly indicated stabilizing effects for most of the measures, but no indication of cumulative effects were observed.
