中文简化版运动病易感性量表的制订与评价

Development and evaluation of the simplified Chinese versions of motion sickness susceptibility questionnaire

目的制订中文简化版运动病易感性量表(MSSQ)长量表(MSSQ-L)和短量表(MSSQ-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3426名大学生发放中文版MSSQ-L和中文版MSSQ-S,根据各项目的乘用率、条目-总分相关系数、Cronbach′sα系数、标准差情况对条目进行筛选,得到中文简化版MSSQ-L和MSSQ-S。在前期调查人群中招募男生、女生各45名,完成Coriolis加速度耐力试验和中文简化版MSSQ-L、中文简化版MSSQ-S和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MSSQ共回收3111份问卷,有效回收率90.8%(3111/3426)。3111名大学生中,男965名,女2146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%(3077/3111)和98.8%(3073/3111)。中文简化版MSSQ-S和中文简化版MSSQ-L分别包含4个和8个条目,Cronbach′sα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MSSQ-S轻度易感者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MSSQ-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MSSQ-S总体预测准确率由中文版MSSQ-S的55.6%(50/90)提升至62.2%(56/90),中文简化版MSSQ-L总体预测准确率由中文版MSSQ-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MSSQ-L和MSSQ-S在信度、效度方面均表现良好,中文简化版MSSQ-S具有良好的区分度,可作为一种简单高效的评估运动病易感性测量工具。

Objective To develop and evaluate the simplified Chinese versions of motion sickness susceptibility questionnaire(MSSQ)-long(MSSQ-L)and MSSQ-short(MSSQ-S).Methods A cross-sectional study was conducted in May 2023 among 3426 university students at North China University of Science and Technology.The Chinese versions of MSSQ-L and MSSQ-S were distributed,and item selection for Simplified Chinese versions of MSSQ-L and MSSQ-S was performed based on item response rates,item-total correlations,Cronbach′s alpha coefficients,and standard deviations.Forty-five male and forty-five female participants were recruited from the initial survey population to complete Coriolis acceleration endurance testing and fill out the simplified Chinese versions of MSSQ-L and MSSQ-S,and Graybiel symptom severity score questionnaire.Internal consistency,external consistency,criterion validity,discriminant validity,and predictive accuracy for motion sickness severity were assessed.Results A total of 3111 valid responses were received for the Chinese versions of MSSQ,yielding an effective response rate of 90.8%(3111/3426).Among the 3111 students surveyed,there were 965 males and 2146 females,with a mean age of(19.5±1.4)years.The highest usage rates for item were observed for cars(98.9%,3077/3111)and buses(98.8%,3073/3111).The simplified Chinese versions of MSSQ-L and MSSQ-S consisted of four and eight items,respectively.The Cronbach′s alpha coefficients were 0.900 and 0.953 for the simplified Chinese versions of MSSQ-S and MSSQ-L,respectively,with test-retest reliabilities of 0.895 and 0.908.Criterion validity coefficients were 0.814 and 0.765 for the simplified Chinese versions of MSSQ-S and MSSQ-L,respectively.In terms of discriminant validity,significant differences were observed between mild and moderate susceptibility groups[0(0,3)vs 6(2,10),P=0.006]and between moderate and severe susceptibility groups[6(2,10)vs 9(6,13),P=0.030]for the simplified Chinese version of MSSQ-S.Significant differences were also observed between mild and moderate susceptibility groups[5(0,3)vs 7(3,10),P=0.001],but not between moderate and severe susceptibility groups[7(3,10)vs 7(3,10),P=0.081]for simplified Chinese version of MSSQ-L.The overall predictive accuracy for motion sickness severity improved from 55.6%(50/90)to 62.2%(56/90)for the simplified Chinese version of MSSQ-S and from 54.4%(49/90)to 58.9%(53/90)for the simplified Chinese version of MSSQ-L,but with no statistically significant differences(both P>0.05).Conclusions The simplified Chinese versions of MSSQ-L and MSSQ-S demonstrates good reliability and validity.The simplified Chinese version of MSSQ-S exhibits satisfactory discriminant validity,and can serve as a simple and efficient tool for assessing motion sickness susceptibility.
