Depressive symptoms, friend and partner relationship quality, and posttreatment abstinence.

OBJECTIVE

This study employed a prospective design to examine the role of friend and partner relationship quality 1 year following substance use disorder treatment in the association between depressive symptoms at discharge from treatment and abstinence from substance use 2 years after treatment.

METHOD: The sample consisted of 1,453 male veterans who used alcohol and at least one other substance in the 3 months before treatment admission, who completed treatment, and who were abstinent from substances during the 2 weeks before discharge.

RESULTS

Fewer depressive symptoms at treatment discharge predicted better relationship quality with friends and a partner at 1-year follow-up, as well as abstinence from substance use at 2-year follow-up. Furthermore, friend and partner relationship quality at 1 year predicted abstinence from substance use at 2 years. Friend relationship quality at 1 year mediated part of the association between fewer depressive symptoms at treatment discharge and abstinence at 2-year follow-up.

CONCLUSIONS

A stronger focus in treatment on reducing depressive symptoms and enhancing the quality of patients' relationships with their friends and partner may increase the likelihood of long-term abstinence.
