The psychometric properties of the italian version of the organizational culture assessment instrument (OCAI)

Abstract

The Competing Values Framework (CVF) has been widely used in organizational research to assess organizational culture. The best-known instrument derived from CVF model, the Organizational Culture Assessment Instrument (OCAI), which measures organizational culture according to four dimensions, is generally presented as valid and reliable. However, only few studies have been conducted for the purpose of validation considering both its ipsative and Likert version; also, this instrument has never been adapted to the Italian context. We used exploratory and confirmatory analyses to examine the underlying structure of data from an Italian adaptation of the OCAI. In the first study, we performed an exploratory factor analysis (EFA) on data from Likert response scale, and multidimensional scaling (MDS) on data from ipsative response scale, and, in the second study, a confirmatory factor analysis (CFA) on data from Likert response scale, obtained from an independent sample. Both MDS and EFA in the first study and CFA in the second study supported the hypothesized four-factor structure, thus indicating that the OCAI Italian version yields good validity and reliability estimates to measure the CVF model.
