Methods: Sixty community residents with schizophrenia or schizoaffective disorder were recruited from a register of previous research participants in an existing genetics study of people with schizophrenia. The WSE-38 was administered via telephone interview, repeated two-five days later. Short-cycle test-retest reliability internal structure, and concurrent validity were assessed. Face validity, utility, consumer and clinician acceptability were examined qualitatively.

Concurrent validity was promising with respect to ...
