行走受损问卷在2型糖尿病患者中应用的信效度评价

目的 评价中文版行走受损问卷(WIQ)在2型糖尿病患者行走能力评估中的信效度.方法 纳入2型糖尿病患者126例,以中文版WIQ问卷、简明健康调查问卷(SF-36)及6 min步行试验(6MWT)为研究工具行资料收集,用信度分析、相关分析、两样本t检验等统计方法评价量表信效度.结果 WIQ量表总的Cronbach's α系数为0.867;WIQ量表的距离、速度、爬梯维度评分及总评分与6 min行走距离(6MWD)相关;WIQ总评分与SF-36测量相同概念反映躯体健康的4个维度评分相关;不同年龄组间WIQ各维度及总评分比较差异显著.结论 中文版WIQ问卷信效度较好,简单、可靠、实用,可用于评估2型糖尿病患者的行走能力.

Evaluation of reliability and validity of application of the Chinese version of walking impairment questionnaire in patients with type 2 diabetic

Objective To evaluate the raliability and validity of walking impairment questionnaire applied to assess the walking ability of patients with type 2 diabetes. Methods One hundred and twenty-six patients with type 2 diabetes were selected. WIQ, SF-36 and 6-minute walk test were used to collect da-ta that was conducted for reliability analysis, correlation analysis and independent-samples t test to evaluate the reliability and validity. Results The internal consistency determined by Cronhach's α was 0.867 for the total WIQ score. Significnat correlations were found between WIQ and 6MWD, also between WIQ and physical domains of SF-36. compared with patients over seventy-one years old, the score of WIQ including the distance, speed, stair climbing and total score is significantly higher than that in patients aged seventy-one or less than seventy-one years old. Conclusions The Chinese version of WIQ is a simple, valid and reliable, clinically relevant tool to assess the walking ability of patients with type 2 diabetes.
