Objective: To examine the responsiveness of the Work Role Functioning Questionnaire (Spanish version) (WRFQ-SpV) so that it could be used in evaluative studies.
Methods: A longitudinal survey was performed. Combinations of distribution- and anchor-based approaches were used. Five hypotheses were tested, examining validity of change scores. The consensus-based standards for the selection of health status measurement instruments (COSMIN) guided the study design.
Results: One hundred two participants (mean age, 47.3 years; SD = 10.3 years) completed the WRFQ-SpV twice, within a mean interval of 3.7 (SD = 1.8) months. Four hypotheses were confirmed and one was rejected. It was verified that the WRFQ-SpV was able to detect (true) changes over time.
Conclusion: Suggestive evidence about the possible use of the WRFQ-SpV with evaluative purposes was provided. More research is needed to examine the instrument responsiveness for groups whose health is stable or deteriorates.
