Measuring the impact of the Capital Card®, a novel form of contingency management, on substance misuse treatment outcomes: A retrospective evaluation
A simple digital points card raised addiction-treatment completion by half again with almost no setup.
01Research in Context
What this study did
Moss et al. (2020) looked back at clinic records. They compared clients who got a digital points card with clients who did not.
The Capital Card gives points for showing up and for clean drug tests. Points can buy small rewards like bus passes or gift cards.
What they found
Clients who used the card were 1.5 times more likely to finish treatment. The boost held after the team controlled for age, gender, and drug of choice.
How this fits with other research
DeFulio (2023) agrees the tech is ready. That review says phone-based rewards work and now only need payment codes and state approval.
SWilson et al. (2023) are going further. Their new trial will add the same kind of point system to opioid programs for stimulant use, but results are not in yet.
Stinson et al. (2023) shows the idea travels. They used a point package to cut college students’ social-media time with the same success pattern.
Why it matters
You can add a digital point card tomorrow. No extra staff training is needed. Start with small rewards for attendance and clean tests. The 1.5-fold gain in completion means fewer drop-outs and more clients reaching recovery goals.

03Original abstract
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. 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). 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.
