Measuring the impact of the Capital Card® on substance use treatment outcomes

To retrospectively evaluate the impact of a digital innovation known as the Capital Card®, a form of contingency management, on treatment outcomes within a community-based substance misuse service. The Capital Card, much like commercial loyalty cards, uses an earn-spend points system that rewards service users for their engagement. The Spend activities are designed to improve overall wellbeing and build social and recovery capital.
We compared treatment 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.
Using a hierarchical logistic regression to predict treatment completion, we compared services user outcomes while controlling for differences in key demographics between the two cohorts. Results showed that the implementation of the Capital Card® was associated with a significantly greater likelihood of successfully completing treatment, with clients being 1.5 times more likely to successfully complete.
The results of this initial evaluation are of particular interest to professionals and researchers within the addictions and mental health fields as it indicates that the Capital Card® can be effectively used as a form of contingency management to enhance recovery outcomes for service users. In addition, this initial evaluation justifies the need for a larger scale evaluation of the Capital Card® which is currently in the early planning stage.
