Escala de Avaliação da Fadiga: funcionamento diferencial dos itens em regiões brasileiras

Abstract

RESUMOEste estudo teve como objetivo conhecer, por meio da ABSTRACT -Fatigue Assessment Scale: Diferential item functioning in Brazilian regionsThis study aimed to understand, through the Item Response Theory, the psychometric parameters and Differential Item Functioning (DIF) of the Fatigue Assessment Scale (FAS). There were 7,008 physicians participating, with a mean age of 47.3 years (SD=11.33), the majority being male (62.4%). We estimated the items' parameters through the Samejima Graded Response Model and the DIF by likelihood ratio, the pseudo-R2 statistics and the differences between the weights of the regressions (∆βs). Results showed good variation of the response thresholds (j) and good discrimination (a). Concerning the DIF, even considering the strictest criteria set forth in the literature, the findings showed a non-significant effect of the region in response to the items. In conclusion, probably the FAS does not have DIF, supporting its use in the Brazilian context.

Validating the Enright Forgiveness Inventory – 30 (EFI-30)

“…However, most of the considerations on discrimination focused on dichotomous items and the weighted cut-off points for these parameters need to increase according to the number of options in the scale studied (Baker & Kim, 2017). This is because, with the increase in the number of response options, there is a greater possibility that the respondents distribute their responses among the different options (Cavalcanti et al, 2016). Even with these observations, the discrimination values of the present study appear to be particularly positive.…”

Evidence of validity, reliability and psychometric parameters of the items of the Cognitive Emotion Regulation Questionnaire-Short (CERQ-Short)

“…At this point, other contexts should be considered, such as sample size and whether the scale will be used in a very specific extract of a population. In large samples and/or samples that have very similar characteristics (specific contexts), there is a greater chance of encountering subjects with close thetas and, therefore, greater need for high discrimination rates (Cavalcanti, Melo, Medeiros, Santos, & Gouveia, 2016).…”

Psychometric properties of the complete version of the World Health Organization Quality of Life Assessment (WHOQOL-OLD): reduced response scale

“…However, according to the author (Baker & Kim, 2017), these indicators were proposed for dichotomous items, and cutoff points considered for these parameters need to increase because of the number of options on the studied scale. There is a need to consider the tendency of increased discrimination of items seen with a higher number of possible answers because, naturally, these respondents would have more chances to be divided according to answer options (Cavalcanti, Melo, Medeiros, Oliveira, & Gouveia, 2016;Tezza, Bornia, & Andrade, 2011). For this reason, comparison of discrimination of scales is sensible because they contain items with a number of different answer options.…”
