Accurate self-report assessment of psychopathology depends on individuals responding honestly and accurately. Some respondents, however, may respond in a manner not representative of their traits/symptoms. The MMPI-2-RF contains “validity” scales to detect elevations on over-reporting (OR) or under-reporting (UR) scales which typically correspond to elevations on MMPI-2-RF substantive scales and on instruments administered alongside the MMPI-2-RF. We examined effects of OR and UR on the Personality Inventory for DSM-5 (PID-5); a self-report instrument that assesses 25 pathological traits used with other diagnostic criteria to diagnose personality disorders (PDs) in Section III of the DSM-5. Using MMPI-2-RF validity scale scores, 908 students and 255 psychiatric outpatients were classified into OR, UR or within normal limit response groups. Significant group differences were found such that differences in the frequency of PD diagnosis emerged across response groups. We believe the PID-5 is vulnerable to OR and UR responding, which potentially compromises its validity.
