整体健康风险模型构建及平行效度与信度评价研究

Development of overall health risk model and its convergent validity and reliability assessment

目的构建整体健康风险模型并评价模型的平行效度和信度。方法采用国人健康风险评估问卷V1．0（CHRAQV1．0）采集某事业单位230名工作人员的健康体检数据，按照主流计分方法，选取CHRAQV1．0中34个项目，构建国人整体健康风险模型；Kolmogorov—Smirnov检验其正态分布，计算Pearson相关系数及Spearman相关系数评价模型的平行效度，通过克兰巴赫q系数、Spearman—Brown系数及重测信度评价模型的信度。结果本研究收回有效问卷212份，回收率92．17％，整体健康风险模型得分为（41．96±9．69）分，峰度系数为2．105、偏度系数为0．862，经Kohnogorov—Smirnov正态性检验，模型得分满足正态分布（Z=1．073，P=0．199）。全部客观检查阳性率与模型得分相关系数r为0．774（P〈0．05）。整体健康风险模型的克兰巴赫仅系数、Spearman—Brown系数、重复测量信度分别为0．652、0．784、0．841（P〈0．05）。结论借鉴健康风险模型主流计分方法和平行效度、信度评价方法，构建了整体健康风险模型。所构建的整体建康风险模型效度、信度较好，在健康管理领域具有一定的应用前景。

Objective To develop an overall health risk model and to evaluate its convergent validity and reliability. Methods Health examination results of 230 adults from a public institution were collected by using Chinese Health Risk Appraisal Questionnaire Vl. 0 （CHRAQ V1.0）. An CHRAQ V1.0- based overall health risk model was then developed,which included 34 items. Kolmogorov-Smirnov was used to test normal distribution of the data. Pearson correlation coefficient and Spearman correlation coefficient were used to evaluate parallel validity of the model. Crane Bach coefficient, Spearman-Brown coefficient and test-retest reliability were calculated to evaluated the reliability of the model. Results In this study, 212 valid questionnaires （92. 17% ） were received. The average score of the newly developed overall health risk model was 41.96±9.69, and its kurtosis coefficient and coefficient of skewness were 2. 105 and 0. 862, respectively. In Kohnogorov-Smirnov, the data were normally distributed （ Z = 1. 073, P = 0. 199 ） . The correlation coefficient of positive rate of all objective examinations with model scores was 0. 774 （ P 〈 0. 05 ）. The Cronbach＇s alpha coefficient, Spearman-Brown coefficient and test-retest reliability of the model were 0. 652,0. 784 and 0. 841 , respectively （ P 〈 0.05 ）. Conclusion In this investigation, our newly developed overall health risk model shows good validity and reliability and application prospect in the field of health management.
