BackgroundSubstance use disorder (SUD) is the continued use of one or more psychoactive substances, including alcohol, despite negative e ects on health, functioning, and social relations. Problematic drug use has increased by 10% globally since 2013, and harmful use of alcohol is associated with 5.3% of all deaths. Direct e ects of music therapy (MT) on problematic substance use are not known, but it may be helpful in alleviating associated psychological symptoms and decreasing substance craving.
ObjectivesTo compare the e ect of music therapy (MT) in addition to standard care versus standard care alone, or to standard care plus an active control intervention, on psychological symptoms, substance craving, motivation for treatment, and motivation to stay clean/sober.
Search methodsWe searched the following databases (from inception to 1 February 2021): the Cochrane Drugs and Alcohol Specialised Register; CENTRAL; MEDLINE (PubMed); eight other databases, and two trials registries. We handsearched reference lists of all retrieved studies and relevant systematic reviews.
Selection criteriaWe included randomised controlled trials comparing MT plus standard care to standard care alone, or MT plus standard care to active intervention plus standard care for people with SUD.
Data collection and analysisWe used standard Cochrane methodology.
Main resultsWe included 21 trials involving 1984 people. We found moderate-certainty evidence of a medium e ect favouring MT plus standard care over standard care alone for substance craving (standardised mean di erence (SMD) -0.66, 95% confidence interval (CI) -1.23 to -0.10; 3 studies, 254 participants), with significant subgroup di erences indicating greater reduction in craving for MT intervention lasting one to three months; and small-to-medium e ect favouring MT for motivation for treatment/change (SMD 0.41, 95% CI 0.21 to 0.61; 5 studies, 408 participants). We found no clear evidence of a beneficial e ect on depression (SMD -0.33, 95% CI -0.72 to 0.07; 3 studies, 100 participants), or motivation to stay sober/clean (SMD 0.22, 95% CI -0.02 to 0.47; 3 studies, 269 participants), though e ect sizes ranged from large Music therapy for people with substance use disorders (Review)
