Evaluation of drug abuse treatments: Based on first year followup.

Long‐term Outcomes After Termination From Methadone Maintenance Treatment*

“…FIGURE 1 summarizes the post-treatment drug use for the 528 interviewed T There were thirteen methadone patients who were admitted to a state hospital program, which subsequently closed. No records were available for these patients.…”

“…Secondly, in order to adjust for incomplete matchings, we utilized analyses of covariance. While this alone is not a sufficient substitute for a randomized design, the procedure does permit a conservative analysis of outcome between groups (see Simpson et al, 1978). Taken together, the matching and the analysis of covariance procedures compensate substantially for the lack of an experimental design, and permit cautious interpretation of the findings, although experimental replication is desirable in the long term.…”

“…They have the poorest posttreatment outcomes and the worst record of behavior problems during therapeutic community treatments, often disrupting treatment activities and dropping out prematurely (McLellan, Druley, & Carson, 1978;Simpson, Savage, Lloyd, & Sells, 1978). Treatment within a methadone maintenance modality is often inappropriate or illegal, since many mixed abusers have not had sufficient opiate abuse to meet FDA admission requirements.…”

“…Only the main effect for tenure was statistically significant (/ ' [3,324] = 3.57, /' = .01); the main effect for type of termination and the interaction term were both nonsignificant (P > .10). Since the classic experimental ANOVA assesses each main effect after statistical adjustment for the others, these findings indicate that the type of termination did not account for any great amount of variance in the composite outcome score after the differences associated with tenure were removed; on the other hand, tenure was associated with outcome differences that could not be accounted for by the termination categories used alone.…”
