Short-Form of the Portuguese version of the positive and negative affect schedule - PANAS-Port-VRP: Confirmatory factorial analysis and temporal invariance
The Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988) is a parsimonious scale. However, several authors suggested that a short-version of the scale is useful. In this study, a short version of the Portuguese PANAS (Galinha & Ribeiro, 2005) was developed....

| Summary: | The Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988) is a parsimonious scale. However, several authors suggested that a short-version of the scale is useful. In this study, a short version of the Portuguese PANAS (Galinha & Ribeiro, 2005) was developed. The study analyzed the factorial structure and the temporal invariance of the short-version in a two month interval. A sample of 245 graduate students and professional training students was collected and replicated in a two month interval. The new short version of the Portuguese PANAS (PANAS-VRP) was then analyzed in a second sample of 535 university students. Results showed that although the structure of the PANAS-VRP was not the same in both samples of the study (what can be explained by the theoretical framework of the scale), it did show good psychometric properties in both samples. The PANAS-VRP also showed temporal invariance in a two month interval and a strong correlation with the original version of the scale in both samples, suggesting that both versions of the scale are measuring the same constructs.DOI: http://dx.doi.org/10.17575/rpsicol.v28i1.622 |
