[Responsiveness to the change in the Work Performance Questionnaire (Spanish version) in a working population].
The objective of this paper is to examine the responsiveness of the Work Role Functioning Questionnaire (Spanish version) ( WRFQ-SpV) so that it could be used in evaluative studies. For this purpose a longitudinal survey was performed. Combinations of distributions-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. One hundred and 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. In conclusion, suggestive evidence about the possible use if 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.
