Determining validity in performance-based measures entirely depends on the examinee’s performance efforts. In contrast, performance-based measures often do not include the validity scales that are included in the self-reported measures. In another self-reported measure known as the Personality Assessment Inventory (PAI), the negative impression (NIM) scale measures distorted responses to provide a negative impression, while positive impression (PIM) measures the attempts to impress to provide a positive impression. The L or K scale in the MMPI-2 can effectively detect under-reporting. The F scale in the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), one of the most well-known self-reported measures, is a scale that can effectively detect examinees who exaggerate psychopathology in the tests. Generally, self-reported measures have validity scales embedded in the tests which could help clinicians determine the over- or under-reporting of symptoms reported by examinees. Thus, ensuring the reliability of the psychological test is very difficult. However, it is not easy for the clinicians to determine whether the examinee has made best efforts in the psychological test based on performance-based measures, self-reported measures, and clinical judgments. ![]() Specifically, the examinee may show a poor effort in the psychological test by over- or under-reporting their symptoms for various reasons, including legal issues, financial gain, stigmas, or refusal of treatment clinicians must be aware of this to obtain valid data. Testifying the validity of the psychological assessment is very important for both the evaluators and for the clinicians who receive the report. While all three indices have utility as embedded PVTs, ACSS ≤ 5 may be most robust to cognitive impairment while identifying noncredible performance.Īssessment elderly/geriatrics/aging malingering/symptom validity testing.After examinees complete a psychological assessment in a psychiatric setting, clinicians judge whether the examinee is making reasonable efforts in performing the psychological test, is reporting exaggerated symptoms, or conversely, under-reporting their symptoms. 39/.86).ĪCSS yielded better classification accuracy and sensitivity/specificity than RDS and RDS-R. 62/.95), and cognitively impaired subsample (≤4. ![]() 62/.87), cognitively unimpaired subsample (≤5.

RDS, RDS-R, and ACSS all significantly predicted validity group membership with respective areas under the curve (AUCs) of. Among valid participants, 49% were cognitively impaired. Those with ≤1 criterion PVT failure were classified as valid (n = 87), whereas those with ≥2 failures were classified as noncredible (n = 26). This study compared the classification accuracy of RDS, RDS-R, and ACSS in a mixed clinical sample of relatively older (M age = 54.61) veterans with and without neurocognitive impairment.ĭuring a comprehensive neuropsychological evaluation, 113 clinically-referred veterans completed the WAIS-IV Digit Span subtest and the following criterion PVTs: Dot Counting Test, Word Choice Test, and Test of Memory Malingering. Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) Reliable Digit Span (RDS), RDS-revised (RDS-R), and age-corrected scaled score (ACSS) are validated and commonly used embedded performance validity tests (PVTs), though existing validation studies have largely examined younger (approximate ages 19-35) patients with mild traumatic brain injury or those without cognitive impairment.
