Circadian rhythms, cyclic fluctuations in many physiological and psychological functions, are thought to influence adjustment to shiftwork. A widely acknowledged individual difference in circadian rhythms, commonly called morningness, indicates preferences associated with morning or evening activities. Various self-report instruments have been developed to measure morningness, although little measurement data have been published for these scales. Because morningness scales are being used to select workers for night shiftwork, psychometric evaluations of these scales are needed. Psychometric assessments of undergraduate responses (N = 501) on three widely used scales indicate internal (interitem) measurement deficiencies in all three. Therefore, a 13-item scale was developed that distills the best items from two of these scales. Relationships between the new composite scale and external criteria are comparable with or stronger than similar relationships between the published scales and external criteria.
昼夜节律是许多生理和心理功能的周期性波动，被认为会影响对轮班工作的适应。昼夜节律中一种被广泛认可的个体差异，通常称为晨型偏好，表明了与早晨或晚上活动相关的偏好。已经开发了各种自我报告工具来测量晨型偏好，尽管针对这些量表公布的测量数据很少。由于晨型偏好量表正被用于选拔夜班工作的工人，因此需要对这些量表进行心理测量学评估。对501名本科生在三个广泛使用的量表上的回答进行的心理测量学评估表明，这三个量表在内部（项目间）测量方面都存在缺陷。因此，开发了一个由13个项目组成的量表，该量表从其中两个量表中提炼出了最佳项目。新的综合量表与外部标准之间的关系与已发表量表与外部标准之间的类似关系相当或更强。
