A review of instruments for measuring functional recovery in those diagnosed with psychosis.
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.
