慢性腰背痛患者康复锻炼保护动机问卷的编制及信效度检验

Development and reliability and validity test of protective motivation questionnaire for rehabilitation exercise in patients with chronic low back pain

目的编制慢性腰背痛患者康复锻炼保护动机问卷,并检验其信效度。方法基于保护动机理论界定维度,通过文献回顾、半结构访谈和专家德尔菲法构建问卷初稿,采取便利抽样法选取220例慢性腰背痛患者进行问卷调查,检验问卷的信效度。结果慢性腰背痛患者康复锻炼保护动机问卷包含6个维度30个条目,探索性因子析出严重性、易感性、内外部奖励、康复价值、自我效能和反应代价6个公因子,累计方差贡献率67.62%;问卷整体Cronbach’sα系数为0.93;问卷整体折半信度为0.86,各维度为0.76~0.92;问卷整体的重测信度为0.91,各维度为0.88~0.93;问卷整体内容效度为0.93,各维度为0.84~1.00;患者康复锻炼保护动机问卷总得分为(89.74±10.28)分。结论构建的慢性腰背痛患者康复锻炼保护动机问卷信效度良好,可用于该类患者康复锻炼保护动机的评估和康复锻炼依从性的预测。

Objective To develop a questionnaire on protective motivation for rehabilitation exercise in patients with chronic low back pain(CLBP)and to test its reliability and validity.Methods Based on the protection motivation theory to define the dimensions,the first draft of the questionnaire was constructed through literature review,semi-structured interviews and expert Delphi,and 220 patients with chronic low back pain attending our hospital were selected by convenience sampling method to test the reliability of the questionnaire.Results The final questionnaire contains 30 entries in 6 dimensions,with 6 metrics analyzed by exploratory factor analysis,and 6 metrics retained,namely,severity,susceptibility,internal and external rewards,recovery value,self-efficacy,and response costs,with a cumulative variance contribution rate of 67.62%.The Cronbach'sαcoefficients for the questionnaire as a whole were 0.93.The folded half reliabilities for the questionnaire as a whole were 0.86,and 0.76 to 0.92 for each dimension.The re-test reliabilities for the questionnaire as a whole were 0.91,and 0.88 to 0.93 for each dimension.The overall content validity of the questionnaire was 0.93,and the content validity of each dimension was 0.84 to 1.00.The total score of the patients on the questionnaire was 89.74±10.28.Conclusion The protective motivation questionnaire for rehabilitation exercise of CLBP patients has good reliability and validity,and can be used to evaluate the protective motivation for rehabilitation exercise and predict adherence to rehabilitation exercise in CLBP patients.
