For the considered outcomes, it seems that adding any psychosocial support to standard maintenance treatments do not add additional benefits. Data do not show differences also for contingency approaches, contrary to all expectations. Duration of the studies was too short to analyse relevant outcomes such as mortality. It should be noted that the control intervention used in the studies included in the review on maintenance treatments, is a program that routinely offers counselling sessions in addition to methadone; thus the review, actually, did not evaluate the question of whether any ancillary psychosocial intervention is needed when methadone maintenance is provided, but the narrower question of whether a specific more structured intervention provides any additional benefit to a standard psychosocial support. These interventions probably can be measured and evaluated by employing diverse criteria for evaluating treatment outcomes, aimed to rigorously assess changes in emotional, interpersonal, vocational and physical health areas of life functioning.
Psychotherapy in community methadone programs: a validation study.
The authors tested the efficacy of individual psychotherapy in the rehabilitation counseling of psychiatrically symptomatic opiate-dependent patients during methadone maintenance treatment in community programs.
                Volunteers in three community programs were randomly assigned to 24 weeks of counseling plus supplemental drug counseling or to counseling plus supportive-expressive psychotherapy. Follow-ups were done 1 and 6 months after treatment ended. A total of 84 subjects were evaluated at both follow-up points.
                During the study the patients receiving supportive-expressive psychotherapy and those receiving drug counseling had similar proportions of opiate-positive urine samples, but the patients receiving supportive-expressive psychotherapy had fewer cocaine-positive urine samples and required lower doses of methadone. One month after the extra therapy ended both groups had made significant gains, but there were no significant differences between groups. By 6-month follow-up many of the gains made by the drug counseling patients had diminished, whereas most of the gains made by the patients who received supportive-expressive psychotherapy remained or were still evident; many significant differences emerged, all favoring supportive-expressive psychotherapy.
                Psychotherapy can be delivered to psychiatrically impaired patients in community methadone programs. Additional counseling is associated with early benefits comparable to those from psychotherapy, but these gains are not sustained. The gains associated with psychotherapy persist and in some cases strengthen for at least 6 months after the end of therapy.
