With expanded scoring and classification, the SIRS-2 was developed to assess deliberate distortions in the self-report of symptoms. Each scale produces useful information on how a particular client may distort or fabricate his or her symptoms. The primary focus of the SIRS-2 is on the evaluation of feigning and the manner in which it is likely to occur—for example, exaggeration of symptom severity versus fabrication of symptomatology.
Demonstrates excellent discriminant validity for feigning versus genuine samples
- Designed to detect response styles commonly associated with feigning and allows for classification as feigning (definite or probable) or genuine responding, as well as identification of inconsistent and other problematic response styles that have implications for therapeutic dynamics and other treatment considerations.
- Revised manual updates the malingering literature with special attention to detection strategies and their clinical applications to feigned mental disorders.
- Two security templates are provided to block item content for instances in which evaluators are legally required to produce SIRS-2 item responses.
- A Spanish-language Interview Booklet is available.
- Thirty-two of the 172 items are repeated inquiries to help you detect inconsistency of responding.
- Utility estimates for classification of feigned mental disorders (based on a base rate of 31.8%) include a sensitivity of .80, a specificity of .975, and positive and negative predictive powers of more than .90.
