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.
Short-term interpersonal psychotherapy in methadone-maintained opiate addicts.
A clinical trial was used to evaluate short-term interpersonal psychotherapy (IPT) as treatment for psychiatric disorders in opiate addicts who were also participating in a full-service methadone hydrochloride maintenance program. Seventy-two opiate addicts were randomly assigned to one of two treatment conditions for six months: (1) IPT, consisting of weekly individual psychotherapy, and (2) low-contact treatment, consisting of one brief meeting per month. Recruitment was a problem, as only 5% of eligible clients agreed to participate and only around half of the subjects completed the study treatment. The outcome was similar for the two study groups. However, in many of the outcome areas, subjects in both treatment conditions attained significant clinical improvement. Several factors limited the generalizability of findings and may have biased against showing a psychotherapy effect.
