N2 - The Perceived Stress Scale (PSS-10) is widely used. Factor-analytic studies have reported a two-dimensional structure (Perceived Stress and Perceived Lack of Control subscales), however, few studies have employed Item Response Theory (IRT) or focused on the issue of differential item functioning (DIF). The Rasch Model (RM) for ordinal data and graphical loglinear Rasch models (GLLRM) were used with data from 1,552 technical and psychology university students. After elimination of item 6 the two subscales were found each to fit a GLLRM. However, lack of conditional independence of the items (LD) and equal item functioning (DIF) were found. The findings point to the need for further construct validity studies of the PSS-10 subscales focusing on the issues of DIF and LD.
