| Abstract: | The Perceived Stress Scale (PSS-10) has been widely used by scholars and practitioners to measure an individual's perceived stress. However, its factor structure is still being challenged, with concerns regarding whether it is unidimensional or multidimensional. This study aims to evaluate the factor structure of the PSS-10. This study collected data from 675 college students (68% females) ages 18-28 (mean = 20.49, SD = 1.42). This study applied a chi-square difference test to compare the unidimensional and multidimensional models. Confirmatory Factor Analysis (CFA) and Multidimensional Graded Response Model (MGRM) were used to assess the PSS-10's factor structure and psychometric properties. The result from CFA and MGRM confirmed the two-factor structure with good reliability (ω ≥.70). In addition, MGRM showed good item discrimination and ordered threshold. The results have confirmed the multidimensionality of the PSS-10 and encouraged the use of the MGRM technique in evaluating instruments' psychometric properties. Furthermore, despite their complexity, the findings show that the two-factor model measured stress more thoroughly and accurately than the unidimensional structure. It offers significant implications for stress measures and interventions to help people manage stress and improve coping skills. [ABSTRACT FROM AUTHOR] |
