Musculoskeletal disorders (MSD) are nowadays seen within a biopsychosocial framework, including salutogenic factors, motivation factors, and coping ability. Such a framework recognizes the importance of motivational factors in health promotion and in rehabilitation. The Motivation for Change Questionnaire (MCQ) has been developed to measure the strength of individuals' motivation for change in life, MCQ part 1, and work situation, MCQ part 2. The purpose of the study was to test the content and concurrent validity of the MCQ on patients with prolonged musculoskeletal disorders referred to interdisciplinary rehabilitation as a basis for use in medical and occupational rehabilitation.
Content validity was studied among an expert group of 20 rehabilitation professionals at a rehabilitation centre, and with 10 individuals suffering from prolonged MSD in the south of Sweden. The experts evaluated the clinical relevance of each question in MCQ. Concurrent validity was studied on 58 patients with prolonged MSD at an interdisciplinary rehabilitation centre in the south of Sweden. They answered MCQ, QPS Nordic questionnaire, KASAM and the Action theory questionnaire. Spearman's rank correlation coefficient was used in the analyses.
The MCQ covered and measured areas of relevance according to content validity. No floor effects in any of the subscales of MCQ part 1 were seen. In MCQ part 2, floor effects were seen in two sub indexes. As for concurrent validity subscales of MCQ correlated significantly with QPS Nordic questionnaire and KASAM.
Findings so far indicate the instrument to be valid for use within the present patient group. The questionnaire can be used to identify patient's motivating factors for change in life and work, as a basis for motivational work within rehabilitation.
如今，肌肉骨骼疾病（MSD）是在生物心理社会框架内看待的，包括健康促进因素、动机因素和应对能力。这样一个框架认识到动机因素在健康促进和康复中的重要性。已经开发了改变动机问卷（MCQ）来测量个体在生活（MCQ第1部分）和工作状况（MCQ第2部分）中改变的动机强度。本研究的目的是测试MCQ在转介至跨学科康复的长期肌肉骨骼疾病患者中的内容效度和同时效度，作为在医学和职业康复中使用的基础。
在一个康复中心的20名康复专业人员专家小组以及瑞典南部10名患有长期MSD的个体中研究内容效度。专家们评估了MCQ中每个问题的临床相关性。在瑞典南部一个跨学科康复中心对58名患有长期MSD的患者进行了同时效度研究。他们回答了MCQ、北欧QPS问卷、KASAM和行动理论问卷。分析中使用了斯皮尔曼等级相关系数。
根据内容效度，MCQ涵盖并测量了相关领域。在MCQ第1部分的任何子量表中均未观察到地板效应。在MCQ第2部分中，在两个子指标中观察到了地板效应。至于同时效度，MCQ的子量表与北欧QPS问卷和KASAM显著相关。
迄今为止的研究结果表明该工具在当前患者群体中有效。该问卷可用于识别患者在生活和工作中改变的动机因素，作为康复中动机工作的基础。
