- Abstract: Thefrequencyofsleepdisturbancesisconsiderablyhigherinthenightandshiftworkersandinfemales than inday workers andmales, respectively.However, asubjectivesleepscale mustbeinvariantacross these groups, independently of the level of their members on the scale. This study is aimed to test the invariance of the Karolinska Sleep Questionnaire’s (KSQ) items by shift work and sex. We used the data fromacensusthatcoveredmorethan90%(N=1648)ofthenursesfromthemaininstituteofthelargest public hospital complex of Brazil. Firstly, we intend to find the KSQ’s dimensionality using factorial analysis and Item Response Theory (IRT) performed by Graded Response Model. Differential Item Functioning (DIF) was the technique used to test the invariance of each KSQ’s dimensions. In case of variancedetection,weappliedthelinkinganalysis.IntendingtotesttheKSQ’sconsistencywithexternal variables, we assessed correlations between KSQ’s dimensions with health variables, i.e., self-reported health status and musculoskeletal pain. We have found one scale and two subscales from one general and another bidimensional factor structure of the KSQ, respectively.
