Using graphical loglinear Rasch models to investigate the construct validity of the Perceived Stress Scale

The Rasch model has been generalized and extended into what is now known
as the class of Rasch models. In this chapter, we will explain in
nontechnical terms the extension known as graphical loglinear Rasch
models (GLLRM), which can be used to test model with departures from the
pure Rasch model in terms of uniform local dependence (LD) or uniform
differential item functioning (DIF). To demonstrate the utility of these
models, we display the psychometric properties of the perceived stress
scale (PSS) in two studies conducted in Australia and Denmark. Although
the studies differed in cultural context, nature of the sample
(nationally representative n = 3,857 and higher education students
n = 1,552), and version of the PSS used (PSS-14 and PSS-10), consistent
results were found. The analysis showed that the PSS consists of two
subscales (Perceived Stress and Perceived Lack of Control), which is
congruent with previous CFA literature. In addition, in both countries
Items 7 and 10 were locally dependent and Items 1 and 3 displayed DIF by
gender. For the Australian nationally representative sample, targeting
was poor for both subscales, while for the Danish sample of higher
education students targeting was excellent. Implications regarding the
application of the PSS are discussed.
