Therapeutic alliance in the treatment of adolescent substance misuse: a systematic review.

BACKGROUND

Therapeutic alliance has been found to play an influential role in predicting outcomes for adults and adolescents in psychotherapy. However, thus far, the information concerning the impact of therapeutic alliance on outcomes for adolescents in treatment for substance misuse has not yet been critically synthesised.

METHODS

In accordance with PRISMA guidelines, the current review aimed to systematically collate published research investigating the association between alliance and outcomes for adolescents undergoing substance misuse treatment. Database searching produced 1083 records, with 16 studies meeting eligibility criteria.

RESULTS

Twelve out of the 16 studies (75%) reported significant alliance-outcome relationships, whereby higher alliance ratings predicted better treatment outcomes, as well as improved engagement and retention in treatment. In addition, the review explored the conditions whereby alliances better predict outcomes, with reference to the alliance rater, the timing of the alliance rating and comorbid diagnoses. These results, however, largely remain inconclusive.

CONCLUSIONS

The evidence as it stands demonstrates the importance of the therapeutic alliance in predicting outcomes for adolescents in substance misuse treatments. The implications of the review's findings and recommendations for future research are discussed.
