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 proposed twelve-factor model. 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 external correlates (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., clinical samples).

Reliability and validity of the French Five-Factor Narcissism Inventory–Short Form.

“…The ESEMs indicated good fits for the three-and two-factor models according to the prescribed criteria (Hooper et al, 2008), although those for the three-factor model appeared superior. These results are in line with past studies corroborating the three-factor latent structure (e.g., Bahrami & Safarloo, 2023;Dai et al, 2021;Jauk et al, 2023). However, the stronger relationship between Antagonism and Agentic Extraversion suggests a bias in the "centrality" of Antagonism.…”

“…Strong correlations between the FFNI-SF-F factors and their corresponding FFM factors (Extraversion, Neuroticism, and Agreeability) were obtained, similarly to other studies (e.g., Jauk et al, 2023;Miller et al, 2016), supporting its construct validity. The moderate association observed between FFNI-SF-F Agentic Extraversion and NEO-FFI-F Extraversion was slightly lower than that obtained in other validations (e.g., Bahrami & Safarloo, 2023;Jauk et al, 2023), and a low negative correlation between FFNI-SF-F Agentic Extraversion and NEO-FFI-F Agreeableness was observed. This is, however, consistent with the moderate correlation obtained between the FFNI-SF-F Agentic Extraversion and FFNI-SF-F Antagonism latent factors in the ESEM, highlighting the "biased centrality" of Antagonism.…”

“…To our knowledge, this study is the first to develop and test a French adaptation of the FFNI-SF. It used ESEM to test the three-factor model, unlike previous studies based on exploratory or confirmatory approaches (e.g., Bahrami & Safarloo, 2023;Dai et al, 2021). With psychometric statistics comparable to other validated measures, the FFNI-SF-F presents itself as a reliable and valid adaptation of the original FFNI-SF.…”
