The Five Factor Borderline Inventory: Behavioral outcomes across time

The Five-Factor Borderline Inventory Short Form (FFBI-SF) is a 48-item dimensional measure of borderline personality disorder (BPD) that was developed from the Five-factor model (FFM). Previous research has examined the relationships of the FFBI-SF to the FFM and BPD. The purpose of the current study was to investigate the relationship of FFBI-SF scales with behavioral outcomes, such as self-injury, physical fights, panic symptoms, promiscuous sex, theft, attempted suicide, reckless driving, and binge eating. A potential advantage of the FFBI-SF, relative to other measures of BPD, is the provision of subscales, which provides a more precise and differentiated assessment. In the current study, the predictive validity of the FFBI-SF in relation to various impulsive behaviors was investigated across a 2-month time period. Additional comparisons were also made with respect to a more traditional measure of borderline personality disorder and an assessment of the normal range of the FFM. Undergraduate students in psychology courses (T1 = 938, T2 = 284, T3 = 163) and workers from Amazon Mechanical Turk (T1 = 215, T2 = 167, T3 = 157) were administered personality measures and a measure of impulsive behaviors across 3 time points. The results are discussed with respect to the comparative validity of the FFBI-SF, relative to traditional measures of borderline personality disorder and the FFM. Overall, the study provided evidence that the FFBI-SF is able to predict specific maladaptive behaviors over time and therefore may be useful in clinical and research settings.
