[Experiences with the validation of the Hungarian version of Personality Inventory for DSM-5 Brief Form: predicting personality disorders based on self-report inventory].

INTRODUCTION: The recent Diagnostic and Statistical Manual of Mental Disorders (DSM-5) provided a dimensional model of personality disorders grounded on the empirical validated concept of maladaptive personality traits. Accordingly, based on this model, the Personality Inventory for DSM-5 Brief Form (PID-5-BF) enables the identification of maladaptive personality traits in 5 dimensions: Negative Affect, Detachment, Antagonism, Disinhibition and Psychoticism. Former studies showed, that this self-report measure can reliably predict the likelihood of the development of personality disorders. AIM: We aimed to develop the Hungarian version of the PID-5-BF and to verify its construct-, concurrent-, predictive-, and discriminative validity. METHOD: Based on the results of former studies regarding PID-5-BF, we asked 379 participants to fill out several selfreport measures. Besides PID-5-BF, the Bipolar Rating Scale for the Big Five Personality, the Unconventionality subscale from the Openness scale of the HEXACO model and the Interpersonal Problems-Personality Disorders-25 were also administered. RESULTS: According to the original 5 factor version, the fit of our model was acceptable (CFI = 0,868; RMSEA = 0,061 [90% CI = 0,055 - 0,068]; Cronbach-alpha = 0,61-0,79). In our view, the results vindicate the reliability and validity of the Hungarian PID-5-BF. CONCLUSIONS: According to former studies along with our recent findings, the PID-5-BF can be seen as an effective and reliable self-report scale for clinical studies and at the same time, it may be useful for the psychiatric diagnostic process, mainly in the case of personality disorders. With more clinical data and knowledge, this inventory could be useful for psychiatrists and clinical psychologists in planning of clinical treatment.
