title: Minnesota Multiphasic Personality Inventory-2 revised form Symptom Validity Scale-Revised (MMPI-2-RF FBS-r; also known as Fake Bad Scale): psychometric characteristics in a nonlitigation neuropsychological setting.
abstract: This study examined fundamental psychometric characteristics of the Symptom Validity Scale-Revised (FBS-r) in a nonforensic sample of 303 neuropsychological referrals. FBS-r had a reliability (internal consistency) of .747 and two higher order factoral dimensions (Somatic Complaints and Optimism/Virtue). FBS-r had a discordant factor structure: Optimism/Virtue (7 items) was negatively related to Somatic Complaints (21 items) and undercut FBS-r measurement consistency (reliability). FBS-r scores, which purportedly reflect symptom exaggeration, are affected by as much as 23 T-score points on test items that are negatively related to symptom reporting. These data suggest that the FBS-r produces ambiguous scores reflecting two underlying dimensions that warrant additional research.
