修改版晕动症易感性问卷用于晕船易感性判断

目的 修改Golding版晕动症易感性问卷(motion sickness susceptibility questionnaire,MSSQ),用以判断中国成年健康男性的晕船易感性,并建立相应分级评价标准.方法 选取121名受试者,填写完整Golding版MSSQ,采用以下方法计算易感指数:MSSQ-R1保留MSSQ中常见晕动调查项目,略去易感指数计算公式中的矫正系数;在MSSQ-R1的基础上,MSSQ-R2和MSSQ-R3分别增加易感指数计算公式中呕吐及恶心症状积分权重;以易感指数百分位数确定易感度等级标准.受试者于海况3～4级条件下利用Graybiel量表判断晕船严重度,并对各易感指数的判断效能进行评估.结果 再测信度为0.85.效标效度方面,各易感指数与Graybiel症状积分间具有正相关关系(P＜0.001),而MSSQ-R3的相关性系数最高,但MSSQ-R3的成年期指数(MSSQ-R3-Adt)相关性优于MSSQ-R3(0.43 vs 0.39);MSSQ-R3判断的重度易感者晕船后Graybiel积分高于中度(P＜0.05)及轻度易感者(P＜0.01),MSSQ-R3-Adt重度及中度易感者Graybiel积分均高于轻度易感者(P＜0.01,P＜0.05),MSSQ-R3-Adt个体易感判断的准确率及人群易感性构成与MSSQ比较差异无统计学意义.结论 修改版MSSQ是一种简单实用且有效的晕船易感性判断方法.

Application of revised MSSQ for seasickness susceptibility evaluation

Objective To revise the Golding form of motion sickness susceptibility questionnaire (MSSQ) for seasickness susceptibility evaluation and grading criteria establishment in Chinese male adults. Methods One hundred and twenty one subjects were selected and filled the complete MSSQ. The MSS indexes were calculated by the following methods: the MSSQ-R1 included the common motion items of MSSQ in the questionnaire and omitted the correction factor in the formula. On the basis of MSSQ-R1, MSSQ-R2 and R3 formula added weighting factor to vomiting and nausea score, respectively. The MSS grading criteria were set based on the percentiles of each MSS indexes. All subjects underwent voyage at sea under 3-4 grade sea condition. Seasickness were assessed by using Graybiel rating scales and the efficacy of the revised MSS indexes was evaluated. Results The retest reliability was 0.85. Aspect of criterion validity, each MSS index positively correlated with Graybiel score (P<0.001) and MSSQ-R3 had the highest correlation coefficient. The correlation of MSSQ-R3 adult index (MSSQ-R3-Adt) was also higher than MSSQ-R3 itself (0.42 vs 0.39). The Graybiel score of high susceptible subjects judged by MSSQ-R3 criteria were higher than those slight (P<0.01) and moderate (P<0.05) ones. The Graybiel score of high and moderate susceptible subjects judged by MSSQ-R3-Adt criteria were higher than those slight ones (P<0.01, P<0.05). No difference was observed in the accuracy of individual susceptibility evaluation and population based susceptibility judged by the MSSQ-R3-Adt criteria compared with those judged by the MSSQ. Conclusion The revised MSSQ is simple, practical and effective for seasickness susceptibility evaluation.
