目的制订中文简化版运动病易感性量表(Ms.q.长量表(Ms.q.L)和短量表(Ms.q.s.并对其进行评价。方法横断面研究。2023年5月向华北理工大学3 426名大学生发放中文版Ms.q.L和中文版Ms.q.s. 根据各项目的乘用率、条目-总分相关系数、c.onbac.′s.α系数、标准差情况对条目进行筛选, 得到中文简化版Ms.q.L和Ms.q.s.在前期调查人群中招募男生、女生各45名, 完成c.riolis.速度耐力试验和中文简化版Ms.q.L、中文简化版Ms.q.s.graybiel症状积分问卷填写, 对中文简化版问卷的内部一致性、外部一致性、效标效度、区分度和运动病严重程度的预测准确率情况进行评估。结果中文版Ms.q.回收3 111份问卷, 有效回收率90.8%(3 111/3 426)。3 111名大学生中, 男965名, 女2 146名, 年龄(19.5±1.4)岁, 小汽车、公共汽车的乘用率最高, 分别为98.9%(3 077/3 111)和98.8%(3 073/3 111)。中文简化版Ms.q.s.中文简化版Ms.q.L分别包含4个和8个条目, c.onbac.′s.α系数分别为0.900、0.953, 重测信度分别为0.895、0.908, 效标效度分别为0.814、0.765。中文简化版Ms.q.s.度易感者graybiel症状积分低于中度易感者[0(0, 3)分比6(2, 10)分, P=0.006], 中度易感者低于重度易感者[6(2, 10)分比9(6, 13)分, P=0.030];中文简化版Ms.q.L轻度易感者graybiel症状积分低于中度易感者[5(0, 3)分比7(3, 10)分, P=0.001], 但中度易感者与重度易感者间差异无统计学意义[7(3, 10)分比7(3, 10)分, P=0.081]。在对运动病严重程度预测准确率方面, 中文简化版Ms.q.s.体预测准确率由中文版Ms.q.s.55.6%(50/90)提升至62.2%(56/90), 中文简化版Ms.q.L总体预测准确率由中文版Ms.q.L的54.4%(49/90)提升至58.9%(53/90), 但差异均无统计学意义(均P>0.05)。结论中文简化版Ms.q.L和Ms.q.s.信度、效度方面均表现良好, 中文简化版Ms.q.s.有良好的区分度, 可作为一种简单高效的评估运动病易感性测量工具。
