Minimum clinically important differences for the Functioning Assessment Short Test and a battery of neuropsychological tests in bipolar disorders: results from the FACE-BD cohort.

The CGI-S and GAF were inappropriate anchors for cognition. Further studies may use performance-based measures of functioning instead.
