Neurocognition and long-term prediction of quality of life in outpatients with severe and persistent mental illness.

The present study examined the predictive validity of neuropsychological measures to quality of life (QOL) indicators in 30 outpatients with severe and persistent mental illness (SPMI), an average of 15 years post-testing. Outcome measures included subscale scores on the Brief Quality of Life Inventory (BQOLI). Results of several stepwise multiple regressions revealed that memory was predictive of income, satisfaction with daily activities, and general health. Executive functioning was predictive of contact with family and financial support. Motor skills were predictive of satisfaction with family contact, and working memory was predictive of victimization and satisfaction with social contacts. Discussion focused on neurocognition as a predictor of QOL, clinical implications, and the potential for improving QOL through cognitive interventions.
