Day treatment with contingency management for cocaine abuse in homeless persons: 12-month follow-up
Milby, J. B., Schumacher, J. E., Wallace, D., Frison, S., McNamara, C., Usdan, S., & Michael, M. (2003). Day treatment with contingency management for cocaine abuse in homeless persons: 12-month follow-up. Journal of Consulting and Clinical Psychology, 71(3), 619-621.
Abstinence, employment, and homelessness treatment outcomes at 12-month follow-up are presented from a study comparing behavioral day treatment plus abstinence-contingent housing and work therapy with behavioral day treatment only among homeless persons who abuse crack cocaine. Within-group improvements were revealed, but group differences for drug abstinence found in J. B. Milby et al. (2000) failed to persist at 12 months. Drug use measurement and treatment termination explanations are discussed. Within- but not between-group differences were found for employment and homelessness outcomes at long-term follow-up. Research extending abstinence contingencies and continuous drug use monitoring is recommended. Questions about effectiveness of contingency management alone, role of coexisting psychiatric disorders on treatment outcome, and individualized treatment dosing are offered.
