Music therapy, neural processing, and craving reduction: an RCT protocol for a mixed methods feasibility study in a Community Substance Misuse Treatment Service.

BACKGROUND: Music therapy has been shown to be effective for multiple clinical endpoints associated with substance use disorder such as craving reduction, emotion regulation, depression, and anxiety, but there are a lack of studies investigating those effects in UK Community Substance Misuse Treatment Services (CSMTSs). Furthermore, there is a demand for identifying music therapy mechanisms of change and related brain processes for substance use disorder treatment. The present study aims to evaluate the feasibility and acceptability of music therapy and a pre-test, post-test, and in-session measurement battery in a CSMTS. METHODS: Fifteen participants, from a community service based in London, will take part in a mixed-methods non-blind randomized-controlled trial. Ten participants will receive six-weekly sessions of music therapy in addition to the standard treatment offered by the CSMTS-five of them will receive individual music therapy and five of them will receive group music therapy-while a further five participants will act as a control group receiving standard treatment only. Satisfaction and acceptability will be evaluated in focus groups with service users and staff members following the final treatment session. Moreover, attendance and completion rates will be monitored throughout the intervention. Subjective and behavioral indexes will be assessed before and after the interventions to explore the effects of music therapy on craving, substance use, symptoms of depression and anxiety, inhibitory control, and will be correlated with associated neurophysiological signatures. In-session analysis of two individual music therapy sessions will serve to explore how music and emotion are processed in the brain within the therapy. The data collected at each step will be included in an intention-to-treat analysis basis. DISCUSSION: This study will provide a first report on the feasibility of music therapy as an intervention for participants with substance use disorder engaged within a community service. It will also provide valuable information regarding the implementation of a multifaceted methodology that includes neurophysiological, questionnaire-based, and behavioral assessments in this cohort. Notwithstanding the limitation of a small sample size, the present study will provide novel preliminary data regarding neurophysiological outcomes in participants with substance use disorder that received music therapy.

Measuring the impact of the Capital Card®, a novel form of contingency management, on substance misuse treatment outcomes: A retrospective evaluation.

BACKGROUND: The Capital Card, developed by WDP, is a digital innovation which acts as a form of contingency management, and aims to significantly improve service user outcomes. WDP is a substance misuse treatment provider commissioned by local authorities across the UK to support service users and their families affected by addiction. The Capital Card, much like commercial loyalty cards, uses a simple earn-spend points system which incentivises and rewards service users for engaging with services e.g. by attending key work sessions, Blood Borne Virus appointments or group-work sessions. The Spend activities available to service users are designed to improve overall wellbeing and build social and recovery capital, and include activities such as educational classes, fitness classes, driving lessons, and cinema tickets. METHODS AND FINDINGS: We compared successful completion rates of 1,545 service users accessing one of WDP's London based community services over a two-year period; before and after the Capital Card was introduced. Client demographics (age, sex and primary substance) were controlled for during the analysis. Once client demographics were controlled for, analysis showed that clients with a Capital Card were 1.5 times more likely to successfully complete treatment than those who had not had the Capital Card (OR = 1.507, 95% CI = 1.194 to 1.902). CONCLUSIONS: The results of this initial evaluation are of particular interest to commissioners and policy makers as it indicates that the Capital Card can be used effectively as a form of contingency management to enhance recovery outcomes for service users engaging in community-based substance misuse services.
