This study aimed to find out whether and to what extent circadian and personality characteristics contribute in determining attitude towards shiftwork. Two groups of female steel plant shift- (n = 54) and dayworkers (n = 54) were matched for age, job tenure, marital status, number, and age of children. The control group was made up of 2 subgroups of dayworkers with (n = 29) and without (n = 25) shiftwork experience. The subjects answered questionnaires on morningness, flexibility, languidity, neuroticism, extroversion, reactivity, and attitude towards shiftwork. Correlation analysis and multiple regression analysis were performed on the data of experimental group and control subgroups separately. Amongst current shiftworkers, the best predictors of attitude towards shiftwork were flexibility of sleeping habits and the ability to overcome drowsiness. Amongst former shiftworkers attitude was determined primarily by reactivity, but in the dayworkers without shiftwork experience no predictors of the attitude were found. The results imply that circadian and personality characteristics related to shiftwork adjustment contribute in determining attitude towards shiftwork.
本研究旨在探究昼夜节律和人格特征是否以及在何种程度上有助于确定对轮班工作的态度。两组女性钢铁厂工人，轮班工人（n = 54）和日班工人（n = 54），在年龄、工作年限、婚姻状况、孩子数量和年龄方面进行了匹配。对照组由两组日班工人组成，一组有（n = 29）轮班工作经验，另一组没有（n = 25）轮班工作经验。受试者回答了关于晨型性、灵活性、慵懒度、神经质、外向性、反应性以及对轮班工作态度的问卷。分别对实验组和对照组的数据进行了相关分析和多元回归分析。在当前轮班工人中，对轮班工作态度的最佳预测因素是睡眠习惯的灵活性和克服困倦的能力。在以前的轮班工人中，态度主要由反应性决定，但在没有轮班工作经验的日班工人中，未发现态度的预测因素。结果表明，与轮班工作调整相关的昼夜节律和人格特征有助于确定对轮班工作的态度。
