The outcomes and costs of 6 different methods of motivating therapists to meet service delivery goals at a community mental health center for children and adolescents were evaluated over a 5-year period. The costs and cost-savings benefits of each motivational method were compared with each other and with two baselines. Four incentive interventions generated more cost savings than they required in monetary outlays. Most cost-beneficial were bonuses paid to therapists for each hour of service they delivered over their monthly goals and bonus plans that rewarded therapists for exceeding their goals while also rewarding staff if total department goals were exceeded. The most cost-beneficial system saved $25,542 over 6 months that would have been paid to compensate for therapy hours not delivered, for an incentive investment of $9,726 over the 6 months. This yielded a net benefit of $15,816, or $31,632 annually.
