As detailed associations between personality and long work hours are unclear, we assessed associations between personality dimensions and overtime work among Japanese white-collar workers.
From records of hours worked over 12 months by 267 office workers in an organization within the service industry, average overtime work hours per month and occurrence of excessive overtime was determined for each worker. Excessive overtime was defined as > 45 overtime work hours per month for at least one month. Responses to a questionnaire assessing socio-demographic and workplace-related factors and the Big Five personality test were analyzed. Associations between personality factors and overtime work were assessed by multivariate logistic regression analysis.
Low Extraversion was associated with excessive overtime work (OR 2.02, 95%CI 1.02 - 4.02, P = 0.04).
It is suggested that workers with low Extraversion can't share work when busy to avoid excessive overtime. Personality factors should be considered in studies evaluating work time. Moreover, strengthening communication among workers with low Extraversion may reduce excessive overtime work and associated health problems.
由于个性与长时间工作之间的具体关联尚不清楚，我们评估了日本白领工人个性维度与加班工作之间的关联。
从服务业一个组织内267名办公室工作人员12个月的工作时长记录中，确定每名工人每月的平均加班时长以及是否存在过度加班情况。过度加班定义为至少有一个月加班时长超过45小时。对一份评估社会人口统计学和工作场所相关因素的问卷以及大五人格测试的回答进行了分析。通过多变量逻辑回归分析评估个性因素与加班工作之间的关联。
外向性得分低与过度加班工作相关（比值比2.02，95%置信区间1.02 - 4.02，P = 0.04）。
提示外向性得分低的工人在忙碌时无法分担工作以避免过度加班。在评估工作时间的研究中应考虑个性因素。此外，加强外向性得分低的工人之间的沟通可能会减少过度加班工作及相关健康问题。
