军队飞行人员昼夜节律类型量表的修订及信效度检验

Revision of Circadian Type Inventory for military flight personnel and its reliability and validity testing

目的修订昼夜节律类型量表(CTI)-11并检验信效度,形成适用于评估军队飞行人员似昼夜节律调节能力的测量工具。方法采用CTI-11对80名军队飞行人员进行预调查,运用经典测量理论修订量表,通过对260名军队飞行人员的二次调查检验修订后量表的信效度。结果修订后的量表由灵活性/刚性以及困倦/活力2个维度10个条目组成,子维度Cronbach’sα系数为0.79和0.64;Spearman-Brown分半信度为0.79和0.60,重测信度为0.90和0.89,问卷总体累积方差贡献率为49.501%。结论修订后的中文版CTI信效度良好,可作为调查军队飞行人员似昼夜节律调节能力的评估工具。

Objective To revise the Circadian Type Inventory(CTI)-11 and examine its reliability and validity,and to develop a measuring tool suitable for evaluating the quasi-circadian rhythm regulation ability of military flight personnel.Methods Eighty military flight personnel were pre-investigated with the CTI-11,and the scale was revised by the classical measurement theory.The reliability and validity of the revised scale were tested by a second survey on 260 military flight personnel.Results The revised scale consisted of 10 items in two dimensions:flexibility/rigidity and languid/vigorous,with Cronbach's α coefficients of 0.79 and 0.64 for subdimensions.Spearman-Brown split-half reliability was 0.79 and 0.60,the test-retest reliability was 0.90 and 0.89,and the overall cumulative variance contribution rate was 49.501%.Conclusion The revised Chinese version of the CTI has good reliability and validity,which can be used as an evaluation tool to investigate the quasi-circadian rhythm regulation ability of military flight personnel.
