Systematic Reviews of Mindfulness and Acceptance and Commitment Therapy for Alcohol Use Disorder: Should we be using Third Wave Therapies?

AIMS: Third wave therapies have shown efficacy for treating emotional disorders and potential for treating substance use disorders. There is developing interest in whether they can more specifically be used for treating alcohol use disorders (AUDs). We were interested in whether third wave therapies have value alongside current evidence-based psychosocial treatments for AUDs.

METHOD: We conducted systematic reviews of third wave therapies for AUDs. We searched PsycINFO, Embase and Medline for peer reviewed journal articles where mindfulness or Acceptance and Commitment Therapy (ACT) were used to treat adults with AUDs or alcohol use that caused impairment.

RESULTS: We identified 11 studies where mindfulness was used for treating AUDs and 6 where ACT was used for AUDs. The studies identified included RCTs, non-randomized controlled studies and uncontrolled studies. We found preliminary support that both third wave therapies are better than no treatment, treatments of minimal efficacy, as well as some evidence they are comparable to effective psychosocial treatments for AUDs.

CONCLUSIONS: We conclude ACT and mindfulness provide an alternative to existing treatments, particularly for patients who have not responded to, or have disengaged from, standard treatments. We also found some evidence ACT and mindfulness are useful for comorbid mental health conditions. Yet while these results are promising, further research is needed to determine their utility, ideally employing randomized-controlled designs, larger clinical samples and longer follow-ups. Furthermore, few studies in this review directly compared third wave therapies to first line treatments, making it difficult to determine their relative efficacy.
