目的 为编制亚健康评定量表,对亚健康评价指标体系进行条目分析与筛选,保留更可靠、更准确、更有代表性的条目,最终形成亚健康评定量表.方法 应用由64个亚健康评价指标构成的自测问卷,选取2 400名研究对象进行测试.采用"临界比率"法对评价指标进行分析;采用离散趋势法、相关系数法、因子分析法、主成分分析法、Cronbach's Alpha系数法对指标进行筛选.结果 除4个总体评价指标不参与分析外,所有指标临界比率的高分组和低分组得分间均存在统计学差异(P<0.01).经6种方法筛选,最后保留39个亚健康评定指标.结论 经条目分析和筛选,最终得到更简化、可靠、准确、具有代表性的亚健康评价指标,达到最初的设计要求,形成亚健康评定量表(第1版),但未来仍需对该量表的信度、效度做进一步检验.
Objective To analyze and screen the items about sub -health evaluation system, so as to keep the more reliable, accurate and representative versions for development of sub - health measurement scale (SHMS) . Methods Totally 2 400 participants were surveyed by using the 64 - item questionnaire. Critical Ratio (CR) method was used for items analysis. The methods of coefficient of variation, coefficient of correlation, factor analysis, principal component analysis and Cronbacb's Alpha coefficient were used to screen the 64 items. Results Score of each item in the questionnaire was statistically significantly different between the high - score - group and the low - score - group, except the overall evaluation indexes (P 〈 0. 01 ). After screened by the 6 methods, 39 sub - health items were retained in the final version. Conclusion After screened by the 6 methods, the finally obtained indexes for sub - health assessment are more simple, reliable, accurate and representative, and thus the Sub - Health Measurement Scale Version 1.0 ( SHMS V1.0) is established and it is up to the request of the initial design. However, the reliability and validity of the scale still need to be tested in the future.
