Abstract
Numerous studies demonstrate the efficacy of contingency management (CM) for improving patient outcomes, yet it is rarely used in treatment settings due to the high cost of implementation. This quasi-experimental study (N = 52) examined the effect of a low-cost "Fishbowl" CM intervention on attendance/retention in an early intervention adolescent substance abuse program. The CM group attended significantly more sessions compared to the control group. Furthermore, the CM intervention costs $3.27 per patient per session. Our findings support the use of low-cost CM to improve adolescent attendance in clinical settings.
