Susceptibility of the Self-Report Psychopathy Scale (SRP 4) to response distortion and the utility of including validity indices to detect deception.
Bibliographic record
Abstract
Self-report psychopathy scales are increasingly used in research and practice despite criticisms that they may be susceptible to response distortion and bias. We assessed the utility of including the Virtuous Responding (VR) and Deviant Responding (DR) validity scales from the Psychopathic Personality Inventory-Revised (PPI-R) for identifying underreporting and overreporting, respectively, on both the full and short-form versions of the Self-Report Psychopathy scale (SRP 4 and SRP-SF) in a pre/post experimental design. Using a sample of 384 male community members and a clinical comparison group of 99 males from a forensic outpatient program, we demonstrated that SRP scores were more susceptible to overreporting than underreporting, and that overreporting significantly and negatively affected convergent validity. Finally, baseline psychopathy scores were unrelated to successful response distortion (i.e., changing scores in correct direction while remaining undetected by the validity scales). It is recommended that assessments using self-report psychopathy scales consider including validity indices to detect response distortion. In doing so, it will be important to consider that general impression management may be conceptually distinct from specific forms of response distortion, such as the intentional amplification or minimization of psychopathic traits.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
