Abstract
OBJECTIVE
The objective of the study is to evaluate the factorial structure and the psychometric qualities of the Pandemic Fatigue Scale among the Quebec adult population.
METHOD
The data analyzed come from a web survey conducted in October 2021 among 10 368 adults residing in Quebec. The scale's factor structure and invariance by gender, age and language used to complete the questionnaire were tested using confirmatory factor analyses. Convergent and divergent validity were also assessed. Finally, the reliability of the scale was estimated from the alpha and omega coefficients.
RESULTS
The analyzes suggest the presence of a bidimensional structure in the sample of Quebec adults with informational fatigue and behavioral fatigue. The invariance of the measure is noted for sex, for age subgroups and for the language used for the questionnaire. The results of convergent and divergent validity provide additional evidence for the validity of the scale. Finally, the reliability of the scale scores is excellent.
CONCLUSION
The results support the presence of a bidimensional structure as in the initial work of Lilleholt et al. They also confirm that the scale has good psychometric qualities and that it can be used among the adult population of Quebec.
