Contingency management for patients with psychotic and substance use disorders
Summary of the evidence
Contingency management in psychotic patients with Substance Use Disorders (SUD) was found in a systematic review with meta analysis (Destoop et al., 2021) to be effective compared to standard care in:
- Improving abstinence rates of drug use, measured by:
- self-reported lower number of days using substance (SMD = −0.52, 95% CI −0.98 to −0.06; p = 0.03
- tendency to more negative breath or urine samples for substance use (OR 2.13, 95% CI 0.97 to 4.69; p = 0.06)
However no differences among retention in treatment (RR 1.15, 95% CI 0.90 to 1.45; p = 0.26).
