Adults diagnosed with schizophrenia smoke cigarettes at excessive rates. The goal of this study was harm reduction by reducing carbon monoxide (CO) levels for 9 adults diagnosed with schizophrenia living in a semi-independent apartment complex. The participants were randomly assigned to one of three groups: Contingent monetary reinforcement (CMR), feedback, and CMR used in combination with feedback. CMR and feedback group was hypothesized to exceed the results of CMR alone and of feedback alone. CO levels were collected once a day for 4 weeks. Individualized CO reduction criteria were developed based on baseline mean CO levels. It was also hypothesized the addition of feedback would lend itself to better maintenance and generalization. Data were analyzed through visual inspection. Results suggested that CMR plus feedback does not improve the effectiveness of CMR alone to maintain reductions in CO levels for adults diagnosed with schizophrenia. Important findings from this study can help alleviate problems for future smoking reduction programs that serve this population.
