| Abstract: | The present study evaluated whether Grooved Pegboard (GPB), when used as a performance validity test (PVT), can incrementally predict psychiatric symptom report elevations beyond memory-apparent PVTs. Participants (N = 111) were military personnel and were predominantly White (84%), male (76%), with a mean age of 43 (SD = 12) and having on average 16 years of education (SD = 2). Individuals with disorders potentially compromising motor dexterity were excluded. Participants were administered GPB, three memory-apparent PVTs (Medical Symptom Validity Test, Non-Verbal Medical Symptom Validity Test, Reliable Digit Span), and a symptom validity test (Personality Assessment Inventory Negative Impression Management [NIM]). Results from the three memory-apparent PVTs were entered into a model for predicting NIM, where failure of two or more PVTs was categorized as evidence of non-credible responding. Hierarchical regression revealed that non-dominant hand GPB T-score incrementally predicted NIM beyond memory-apparent PVTs (F(2,108) = 16.30, p <.001; R2 change =.05, β = −0.24, p <.01). In a second hierarchical regression, GPB performance was dichotomized into pass or fail, using T-score cutoffs (≤29 for either hand, ≤31 for both). Non-dominant hand GPB again predicted NIM beyond memory-apparent PVTs (F(2,108) = 18.75, p <.001; R2 change =.08, β = −0.28, p <.001). Results indicated that noncredible/failing GPB performance adds incremental value over memory-apparent PVTs in predicting psychiatric symptom report. [ABSTRACT FROM AUTHOR] |
