The Polish adaptation of the Five-Factor Obsessive-Compulsive Inventory – Short Form (FFOCI-SF): A preliminary study

Abstract

BackgroundThe Five-Factor Obsessive-Compulsive Inventory – Short Form (FFOCI-SF) is an instrument used to measure obsessive-compulsive personality disorder, which is one of the most widespread personality disorders. The FFOCI-SF is a shorter version of the FFOCI that was developed on the basis of the Five Factor Model of per-sonality treated as a general framework for identifying different traits useful in describing maladaptive person-ality. This paper presents the psychometric parameters of the Polish adaptation of the FFOCI-SF.Participants and procedureOur sample consisted of 328 respondents aged 18-75 (61% women) from Poland. The voluntary and anony-mous procedure consisted of completing inventories in a self-reported, paper-and-pencil way. The respondents received the FFOCI-SF, the Personal Inventory for DSM-5 (PID-5) and the Big Five Inventory-2 (BFI-2).ResultsThe findings suggest that there is acceptable internal consistency for most of the scales and some problems with the differentiation between some scales in factor analysis. Additionally, we present the hierarchical struc-ture of the facets included in the instrument with two factors analogous to the metatraits of personality (Alpha and Beta). The criterion validity of the inventory was established by correlations on the one hand with Big Five traits (BFI-2) and on the other hand with another measure of the obsessive-compulsive personality disorder traits, namely appropriate scales from the Personality Inventory for DSM-5 (PID-5).ConclusionsThis study confirms that the FFOCI-SF is a valid measure for scientific purposes. In order to use it for diagnostic purposes, further research is suggested on clinical samples. The findings also suggest that the FFOCI-SF can be useful in exploring new solutions in structure of the obsessive-compulsive personality disorder facets.
