Psychometric properties of the Persian version of short-form five factor borderline inventory (FFBI-SF)

Abstract

Background The Five-Factor Borderline Inventory-Short Form (FFBI-SF) is a self-report measure developed to assess traits of Borderline Personality Disorder (BPD) from the perspective of the Five-Factor Model of general personality. This study was designed to examine the factor structure, internal consistency, and convergent/discriminant validity of the Persian FFBI-SF in a sample of Iranian university students. Methods A total of 641 university students (M-age = 28.04, SD = 8.21, 66.7% women) completed the online forms of the FFBI-SF, PID-5-BF, and Mini IPIP. Results Confirmatory factor analysis supported the original and modified (without item 47) twelve-factor models. Also, Cronbach’s alpha (α) for the FFBI-SF scores ranged from unacceptable to excellent ranges. However, when relying on MIC values to measure internal consistency, the FFBI-SF Total and subscale scores demonstrated adequate internal consistency. Finally, the FFBI Total and subscale scores showed the expected relations with other personality measures scores (e.g., Neuroticism, Antagonism, and Conscientiousness), which supports the validity of the interpretation of the FFBI-SF scores. Conclusions The findings indicated that FFBI-SF is a useful tool with sound psychometric properties for assessing BPD traits in Iranian students and may spark research in other Iranian settings (e.g., community and clinical samples).

Polish adaptation of self-report instruments for studying borderline personality traits – FFBI and FFBI-SF

“…Cronbach's alpha values similar to the original version of FFBI [19] were expected, where all scales had coefficients above 0.77 (M α = 0.86) and in FFBI-SF above 0.71 (M α = 0.80). Similar values were also obtained in the Persian version of FFBI-SF, where the mean Cronbach's alpha score was 0.70 [23], and in the French FFBI-SF -M α = 0.78 [24]. 2) Structural validity, i.e., the 12-factor structure of the Polish version of the FFBI and FFBI-SF, similar to the original versions -full [19] and shortened [20], as well as shortened versions of the Persian [23] and French [24] adaptations.…”

The fit of the theoretical model to the data was assessed on the basis of the following indicators: CFI (Comparative Fit Index), RMSEA (Root Mean Square Error of Approximation) and WRMR (Weighted Root Mean Square Residual).…”
