Evaluation of the factor structure of the Russian version of PID-5-BF

INTRODUCTION: Traditional categorical classifications of personality disorders (PD) have been criticized for insufficient structural and cross-cultural validity. In the DSM-5 Section III, alternative model of the PDs (AMPD), the maladaptive personality traits are divided into five domains: negative affect, detachment, antagonism, disinhibition and psychoticism. The Personality Inventory for DSM-5 Brief Form (PID-5-BF) is a 25-item self-report questionnaire that measures the severity of each of these five domains. To date, no questionnaires assessing pathological personality traits following the AMPD have been validated in Russia. OBJECTIVES: This study aimed to investigate the factor structure of the Russian version of PID-5-BF. METHODS: Five hundred and 86 (female - 505 (86,2%), age - 18–77 years (M - 28.2, SD - 11.5)) consecutive inpatients with non-psychotic mental disorders were assessed with the Russian language version of the PID-5-BF. Exploratory structural equation modelling (ESEM) with Robust Diagonally Weighted Least Squares method of extraction and Robust Equamax rotation was performed in Factor v 11.04.02. RESULTS: The results of the ESEM analysis showed good fit of the five-factor model (CFI - 0.982; TLI - 0.971; RMSEA (95% CI) - 0.036 (0.01-0.05). Most of the items had the highest factor loadings on their mother domains. However, two items showed weak loadings on their designated factors (<0.4), and attention seeking item had a primary load to (low) detachment instead of antagonism. CONCLUSIONS: The PID-5-BF was found to be a valid and reliable tool for the evaluation of the AMPD trait domain DISCLOSURE: No significant relationships.
