The Work Role Functioning Questionnaire (Spanish version) (WRFQ-SpV) effectively detects changes over time, supporting its use in evaluative studies. Further research is needed for stable or deteriorating health groups.
Area of Science:
- Psychometrics
- Occupational Health
Background:
- The Work Role Functioning Questionnaire (Spanish version) (WRFQ-SpV) is a tool for assessing work role functioning.
- Its responsiveness for evaluative purposes requires examination.
Purpose of the Study:
- To evaluate the responsiveness of the WRFQ-SpV for use in evaluative studies.
- To determine if the WRFQ-SpV can detect true changes in work role functioning over time.
Main Methods:
- Longitudinal survey design guided by COSMIN standards.
- Combined distribution- and anchor-based approaches.
- Tested five hypotheses on the validity of change scores.
Main Results:
- 102 participants completed the WRFQ-SpV twice over a mean interval of 3.7 months.
- Four of five hypotheses were confirmed.
- The WRFQ-SpV demonstrated ability to detect true changes over time.
Conclusions:
- The WRFQ-SpV shows potential for evaluative use.
- Further research is recommended for populations with stable or deteriorating health.
