The task of judging an individual's functional recovery is not an easy one for healthcare professionals. Indeed, increasing one's accuracy in predicting one's ability to self-maintain would be of great value for determining if functional recovery has or is occurring. The purpose of this review is to examine existing measures for assessing remission/normalization of functional status among people with psychosis. Our review evaluates 8 measures of functional ability encompassing self-report, clinical, and performance-based measures. We elected to utilize a grading system to aid readers in understanding the merit of a scale for use in assessing functional recovery. In this approach, a letter grade (A, B, or C) was assigned to each of 4 domains we deemed important to professionals in electing to use specific assessments: (1) Ease of Administration, (2) Reliability, (3) Validity/Relationship to Real-World Outcomes, and (4) Sensitivity to Change/Use in Clinical Trials. Results indicated that no "gold standard" measure has been developed to date, but performance-based measures appear to have the most evidence for predicting concurrent self-maintenance abilities (eg, residing independently or maintaining work). More research on existing measures is needed, and greater funding for developing new measures of functional recovery is strongly recommended.
