A-177 Classification Statistics of the Clinical Assessment of Attention Deficit – Adult (CAT-A) Negative Impression Scale for ADHD Evaluations in an Active Duty Sample

Abstract Objective To evaluate the classification statistics of Clinical Assessment Attention Deficit – Adult (CAT-A) Negative Impression (NI) scale, relative to MMPI-2-RF in an active duty military sample. We hypothesized that RBS would have largest AUC. Method Retrospective review 108 service members consecutively referred neuropsychology for clinical ADHD evaluations a Midwest Army Health Center. Cases with missing data (10) and failures response consistency scales (3) were removed from analysis, resulting final sample 95. Average age was 32.62 (SD = 8.87) average education 14.66 2.66). symptom validity (F-r, Fp-r, Fs, FBS-r, RBS) employed as criterion measures at all standard cut-offs CAT-A NI scale. Results ROC analyses over-reporting ranged 0.599 0.808, scale >79 demonstrating lowest AUC (0.599; p 52. With specificity held or above 0.90, sensitivities 22.86 60.00, positive negative predictive values ranging 11.1 58.8 66.7 98.8, respectively. Conclusions The demonstrated reasonable nearly scales. Psychologically-based superior cognitively-based terms statistics. optimal cut current (>52) is slightly higher (though roughly commensurate) score atypical responses manual (>45).
