The Credit-Incentive system: motivating the participation of patients in a day hospital

The Credit-Incentive System, a modified token economy, is a means of motivating the participation of day hospital patients in therapeutic activities through the use of contingent rewards. Credits are earned by patients for engaging in a wide variety of prosocial tasks and activities and can be spent for coffee, a free lunch, special time with professional staff, recreational events, and time off from the treatment centre. The receipt of credits is accompanied by social approval and recognition from the staff and other patients. Evaluations have shown that the credit system doubles the participation rate of patients in a partial hospitalization programme. The system also enhanced group cohesiveness, provides practice and feedback for cognitive re-integration, and offers opportunities of learning self-management. The results of two experiments suggest that the symbolic and social rewards mediated by the credits are the most important components of their effectiveness.
