青少年亚健康多维评定问卷在库区中学生中的应用考评

Evaluation of the Multidimensional Sub-health Questionnaire of Adolescents

目的考评《青少年亚健康多维评定问卷》(multidimensional sub-health questionnaire of adolescents,MSQA)在库区中学生中的信度和效度。方法采用分层整群随机抽样的方法,随机抽取库区中学生1 522名,运用MSQA进行自我评定,1周后对其中218名库区中学生进行重测,同时运用症状自评量表(SCL-90)、Cornell医学指数(CMI)问卷进行自我评定。采用重测信度和内部一致性信度考评问卷的信度,用结构效度和效标效度考评问卷的效度。结果 MSQA总问卷、躯体亚健康领域、心理亚健康领域及各维度得分的重测相关系数分别为0.941、0.926、0.901、0.838、0.822、0.831、0.923、0.913、0.934(P<0.01);MSQA总问卷得分的Cronbach'sα系数为0.961,分半信度系数为0.938,躯体亚健康领域、心理亚健康领域及各维度得分的Cronbach'sα系数为0.711～0.921,而分半信度系数为0.697～0.915。各维度与所属领域得分的相关系数为0.813～0.952(P<0.01);SCL-90问卷精神症状部分总得分与MSQA心理亚健康领域问卷总得分的相关系数为0.766(P<0.01),CMI问卷躯体症状部分总得分与MSQA躯体亚健康领域总得分的相关系数为0.575(P<0.01)。结论 MSQA具有较好的信度和效度,可作为定量评价库区中学生亚健康的工具。

Objective To evaluate reliability and validity of the Multidimensional Sub-health Questionnaire of Adolescents（MSQA）.Methods The stratified cluster random sampling was taken for choosing 1 522 middle school students from Chongqing Three Gorges reservoir areas.All the students were surveyed with MSQA,and one week later,218 of them were re-tested with the MSQA and also with Symptom Check List-90（SCL-90） and Cornell Medical Index（CMI）.Test-retest reliability and internal consistency reliability were used to evaluate reliability of MSQA,and construct validity and criterion-related validity were used to evaluate validity of MSQA.Results The test-retest correlation coefficients of whole questionnaire,somatic sub-health domain,mental sub-health domain and each dimension were 0.941,0.926,0.901,0.838,0.822,0.831,0.923,0.913 and 0.934 respectively（P〈0.01）.The Cronbach′s α coefficient and split-half reliability coefficient of whole MSQA questionnaire were 0.961 and 0.938 respectively.The Cronbach′s α coefficient of each dimension and each domain of MSQA were 0.711~0.921,while split-half reliability coefficient were 0.697~0.915.The correlation coefficient of each dimension and its domain were 0.813~0.952（P〈0.01）.The correlation coefficient between total score of mental symptom of SCL-90 and total score of mental sub-health domain of MSQA was 0.766（P〈0.01）.The correlation coefficient between total score of somatic sub-health of CMI and total score of somatic sub-health of MSQA was 0.575（P〈0.01）.Conclusion MSQA has a good reliability and validity,and it may be taken as an instrument to assess sub-health of middle school students of Three Gorges reservoir areas.
