WERC Screening Instruments

The screening instruments described below were developed at WERC primarily for research use, and can be downloaded for free. They may also be useful for screening of youths in community and clinical settings. All instruments are completed by the respondent.

Disclaimer: Results obtained from these instruments should not substitute or supersede the opinion of an experienced mental health professional. Results may be unrelated to the presence or absence of a mental disorder.

  1. WERC Affectivity and Psychosis Screen (WERCAP Screen):
    WERCAP Screen was designed to assess the risk for developing bipolar and psychotic disorders in the future. It can also estimate the severity of affective and psychotic symptoms. Obtained scores correspond to the time period specified in the designated “period” box or over a lifetime (default). Questions 1-8 probe affective symptoms, and questions 9-16 probe psychotic symptoms. Affective and psychotic symptoms are scored separately. Scores are generated by a sum of frequency ratings (0-5) and frequency ratings (0-3). Estimated time for completion: 3-6 minutes.
