Contingency management for the treatment of antipsychotic-induced weight gain : a randomized controlled pilot study . OBJECTIVE Weight gain is common for individuals with serious mental illness ( SMI ) receiving antipsychotic drug therapy . Contingency management ( CM ) is a behavioral intervention that rewards positive performance and has demonstrated effectiveness in reducing drug use in SMI populations . This study evaluated the feasibility of using CM to promote weight loss in individuals with SMI over 8 weeks . METHOD 30 individuals ( BMI ≥ 28 kg/m ( 2 ) ) were randomized to one of three conditions : i ) The combination of a standardized lifestyle modification ( LM ) program for individuals with SMI and payment for group attendance ( CM ( attendance ) ) , ii ) The combination of LM and payment for weight loss ( CM ( weight ) ) , and iii ) waitlist control ( CON ) . After the waitlist period , those participants joined a LM group and received payment for behavioral change ( CM ( behavior ) ) . RESULTS Subjects in the CM ( attendance ) and in the CM ( weight ) group lost a mean of 1.16 kg and 1.23 kg , respectively , while subjects in the CON gained a mean of 0.68 kg . Subjects receiving CM ( behavior ) , lost a mean of 2.54 kg , which was a significant weight loss compared to the control period . CONCLUSION LM supplemented with CM may facilitate weight loss in patients taking antipsychotic medications ; financial reimbursement for behavioral change may be particularly effective in this population .
