This study was conducted with the aim of developing a standard and valid questionnaire to evaluate the behavioral factors affecting musculoskeletal disorders among adolescent students based on the educational and ecological diagnosis phase of the PRECEDE model.
Based on the PRECEDE model and by using available resources and a panel of experts, a reservoir of items was proposed. The content validity of the questions was measured using content validity ratio (CVR) and content validity index (CVI). 400 Iranian first-year female high school students completed the questionnaire. The construct validity was assessed using confirmatory factor analysis (CFA). The reliability of the questionnaire was evaluated using Cronbach's alpha coefficient.
The age range of study students was 13.69 ± 0.86 years. The final developed questionnaire included 25 items in three dimensions: knowledge (9 items), attitude (10 items) and enabling factors (6 items). The mean scores of CVI and CVR were 0.97 and 0.92, respectively. The results of CFA confirmed the three-factor structure of the questionnaire. The Cronbach's alpha coefficients of the dimensions of knowledge, attitude and enabling factors were 0.65, 0.80 and 0.71, respectively.
The present questionnaire had appropriate psychometric properties and could be used as a valid tool in evaluating the factors affecting the development of musculoskeletal disorders among adolescent students.
本研究旨在根据 PRECEDE 模型的教育和生态诊断阶段，开发一种标准且有效的问卷，以评估影响青少年学生肌肉骨骼疾病的行为因素。
基于 PRECEDE 模型，并利用现有资源和专家小组，提出了一个项目储备库。使用内容效度比（CVR）和内容效度指数（CVI）来衡量问题的内容效度。400 名伊朗一年级女高中生完成了问卷。使用验证性因子分析（CFA）评估结构效度。使用 Cronbach's alpha 系数评估问卷的信度。
研究学生的年龄范围为 13.69±0.86 岁。最终开发的问卷包括三个维度的 25 个项目：知识（9 个项目）、态度（10 个项目）和促成因素（6 个项目）。CVI 和 CVR 的平均得分分别为 0.97 和 0.92。CFA 的结果证实了问卷的三因素结构。知识、态度和促成因素维度的 Cronbach's alpha 系数分别为 0.65、0.80 和 0.71。
本问卷具有适当的心理测量学特性，可作为评估影响青少年学生肌肉骨骼疾病发展因素的有效工具。
