Abstract
Introduction:
the Work Rehabilitation Questionnaire (WORQ) was created to assess the functioning and disability of workers undergoing rehabilitation. Since it is comprehensive, it is assumed that its use for a population of active workers can be useful.
Objective:
to evaluate the construct validity and the reliability of the self-reported WORQ translation to Brazilian Portuguese, in active workers population.
Methods:
we applied the WORQ to a random sample of workers from the Federal University of Acre, Brazil. For construct validation, we raised hypotheses and analised correlations between the WORQ and the instruments: WHOQOL-BREF, WHODAS, PHQ-9, and GAD-7. For assess reliability, we used the test-retest methodology in a sub-sample (n=50), followed by the calculation of the Spearman coefficient. For internal consistency, we calculated the Cronbach’s alpha.
Results:
241 workers participated, 50.2% female. The WORQ showed a strong correlation with WHODAS (r=0.782), moderate with PHQ-9 and GAD-7 (r=0.68 and r=0.675) and a moderate inverse correlation with WHOQOL (r=−0.671). We calculated a Cronbach´s’ alpha of 0.95, and a Spearman’s correlation coefficient of 0.86.
Conclusion:
the WORQ presented suggestive evidence of construct validity and reliability for use with active workers. Its use in screening for disabilities in these workers may be suggested.
