The Alternative Model for Personality Disorders (AMPD) is proposed by the Diagnostic and Statistical Manual for Mental Disorders-5 (DSM-5) to explore the severity and the style of pathology in personality. The current study was designed to examine cross-cultural validation of the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF 2.0) and Personality Inventory for DSM-5-Short Form (PID5-SF) in Pakistan. Data were collected from 361 convicts imprisoned in Central Jails of Bahawalpur and Sahiwal. The construct validity of the translated instruments was established by reporting good to excellent model fit tested through confirmatory factor analysis (CFA). Structural equation modeling (SEM) supported the new personality disorder diagnostic system proposed by Section III of DSM-5. LPFS-BF 2.0 and PID5-SF are short, valid, and reliable instruments that can be administered to a unique sample of offenders, especially prisoners, to measure personality pathology. In Pakistan, such instruments are needed to assess the mental health of prisoners effectively and efficiently.
