OBJECTIVE
The 25-item Work Limitations Questionnaire (WLQ-25) measures presenteeism but has not been sufficiently validated in a Japanese population.
METHODS
A total of 451 employees from four information technology companies in Tokyo completed the WLQ-25 and questionnaires of other variables on two occasions, 2 weeks apart.
RESULTS
The WLQ-25 yielded a two-factor structure: Cognitive Demand and Physical Demand. These subscales showed good internal consistency, and both were associated with adverse working conditions, greater perceived job strain, lower skill use, poorer workplace social support, and less satisfactory psychological adjustment. Intraclass correlation coefficients of the two WLQ-25 subscales between time 1 and time 2 were 0.78 and 0.55, respectively.
CONCLUSIONS
This study suggests acceptable psychometric properties of the WLQ-25 in Japan.
目的
25 项工作限制问卷（WLQ-25）用于衡量出勤主义，但尚未在日本人群中得到充分验证。
方法
共有来自东京的四家信息技术公司的 451 名员工在两周的时间间隔内分两次完成了 WLQ-25 及其他变量的问卷。
结果
WLQ-25 产生了两个因素结构：认知需求和身体需求。这些分量表表现出良好的内部一致性，并且都与不良的工作条件、更大的感知工作压力、较低的技能使用、较差的工作场所社会支持以及更不满意的心理调整相关。两个 WLQ-25 分量表在时间 1 和时间 2 之间的组内相关系数分别为 0.78 和 0.55。
结论
本研究表明 WLQ-25 在日本具有可接受的心理测量特性。
