Abstract：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.
