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.
本文的目的是检验工作角色功能问卷（西班牙语版）（WRFQ-SpV）的反应性，以便其能用于评估研究。为此开展了一项纵向调查。采用了基于分布和锚定的方法组合。测试了五个假设，检验变化分数的有效性。基于共识的健康状况测量工具选择标准（COSMIN）指导了研究设计。102名参与者（平均年龄47.3岁；标准差=10.3岁）在平均间隔3.7（标准差=1.8）个月内两次完成WRFQ-SpV。四个假设得到证实，一个被拒绝。证实WRFQ-SpV能够检测随时间的（真实）变化。总之，提供了关于WRFQ-SpV用于评估目的的可能性的提示性证据。需要更多研究来检验该工具对健康稳定或恶化群体的反应性。
