The article presents the construction of the short form Polish version of Multidimensional Work Ethic Profi le (WPEP-s). The original version of Multidimensional Work Ethic Profi le (WPEP) consisted of 65 items. To shorten the questionnaire, (1) Exploratory Factor Analysis (EFA) was carried out, (2) Item-to-Total Correlations (ITC) test used and (3) content analysis was carried out. In the end, 35 items of the highest factor loadings and ITC values were applied. However, the items of similar and repeated content were removed. The short form received satisfactory indicators of factor validity and internal consistency. Confi rmatory Factor Analysis (CFA) showed satisfactory fi t of data to seven-factor theoretical model, which was the basis for creating 65-item version. The studies carried out show that the short form of WPEP-s is similar to the original 65 items version of WPEP.
