BACKGROUND
The Effective Musculoskeletal Consumer Scale (EC-17) is a self-administered questionnaire for evaluating self-management interventions that empower and educate people with rheumatic conditions. The aim of the study was to translate and evaluate the Norwegian version of EC-17 against the necessary criteria for a patient-reported outcome measure, including responsiveness to change.
METHODS
Data quality, reliability, validity and responsiveness were assessed in two groups. One group comprising 103 patients received a questionnaire before and at the end of a self-management programme. The second group comprising 96 patients' received the questionnaire two weeks before and on arrival of the program. Internal consistency and test-retest reliability were assessed. Construct validity was assessed through comparisons with the Brief Approach/Avoidance Coping Questionnaire, (BACQ), the Emotional Approach Coping Scale (EAC) and the General Health Questionnaire (GHQ-20). Responsiveness was assessed with the Standardised Response Mean (SRM).
RESULTS
Respondents included 66 (64%) and 52 (54%) patients from the first and second groups respectively. Levels of missing data were low for all items. There was good evidence for unidimensionality, item-total correlations ranged from 0.59 to 0.82 and Cronbach's Alpha and test-retest correlations were over 0.90. As hypothesised EC-17 scores had statistically significant low to moderate correlations with the BACQ, EAC and GHQ-20 in the range 0.26 to 0.42. Following the self-management program, EC-17 scores showed a significant improvement with an SRM of 0.48.
CONCLUSION
The Norwegian version of the EC-17 has evidence for data quality, internal consistency and test-retest reliability, construct validity and responsiveness to change. The EC-17 seems promising as an outcome measure for evaluating self-management interventions for people with rheumatic conditions, but further studies are needed.
背景
有效肌肉骨骼消费者量表（EC-17）是一种自我管理干预措施的自我管理问卷，旨在增强和教育风湿性疾病患者的能力。本研究的目的是翻译和评估挪威版本的 EC-17，以满足患者报告结果测量的必要标准，包括对变化的反应能力。
方法
在两个组中评估数据质量、可靠性、有效性和反应能力。一组 103 名患者在自我管理计划开始前和结束时接受了问卷调查。第二组 96 名患者在计划开始前两周和到达时接受了问卷调查。评估内部一致性和测试-重测可靠性。通过与简要回避应对问卷（BACQ）、情绪应对量表（EAC）和一般健康问卷（GHQ-20）进行比较来评估结构有效性。通过标准化反应均值（SRM）评估反应能力。
结果
第一组和第二组分别有 66（64%）和 52（54%）名患者回答了问卷。所有项目的缺失数据水平均较低。存在良好的单维性证据，项目-总分相关性在 0.59 至 0.82 之间，Cronbach's Alpha 和测试-重测相关性均超过 0.90。假设 EC-17 评分与 BACQ、EAC 和 GHQ-20 之间存在统计学上显著的低至中度相关性，范围为 0.26 至 0.42。经过自我管理计划后，EC-17 评分显著提高，标准化反应均值为 0.48。
结论
挪威版 EC-17 具有数据质量、内部一致性和测试-重测可靠性、结构有效性和对变化的反应能力的证据。EC-17 似乎有望成为评估风湿性疾病患者自我管理干预措施的结果测量指标，但需要进一步研究。
