Results indicated that the MMPI-2 F - K index and Fp Scale were the best single indicators of a faking bad response style and that the MMPI-2 scales were the better indicators as a set. The 2 measures were administered to 52 college students instructed to fake bad under conditions describing either a forensic (n = 24) or psychiatric (n = 28) setting as well as to 432 psychiatric patients. This study directly compared the effectiveness of the 2 inventories as indicators of overreporting. Both the Minnesota Multiphasic Personality Inventory-2 (MMPI-2 Butcher et al., 2001) and Personality Assessment Inventory (PAI Morey, 1991) offer a large set of scales devoted to the identification of response styles.
