Impact of cognitive remediation on the prediction of employment outcomes in severe mental illness.

OBJECTIVE

Cognitive functioning is a potent predictor of work in people with a severe mental illness, including those receiving vocational services. Cognitive remediation has been shown to improve cognitive functioning and work outcomes in people receiving vocational services. However, it is unknown whether it reduces the strength of cognitive functioning as a predictor of work outcomes compared to people receiving vocational services alone.

METHOD

Data were pooled from five randomized controlled trials evaluating the effects of adding cognitive remediation to vocational rehabilitation vs. vocational services alone. A battery of baseline cognitive functioning measures was examined to identify predictors of competitive work outcomes over the following two years. Study condition (i.e., receipt of cognitive remediation) was included in the analyses to evaluate whether cognitive functioning was a weaker predictor of work outcomes in people receiving cognitive remediation compared to those receiving vocational services alone.

RESULTS

Cognitive functioning was a stronger predictor of wages earned and weeks worked in participants receiving vocational services alone than those who also received cognitive remediation. Cognitive functioning did not predict job acquisition in either study condition.

CONCLUSION

Cognitive remediation may improve employment outcomes in people receiving vocational services in part by reducing the adverse effects of impaired cognitive functioning on work performance.
