The objective of this study was to verify whether the assessment of poor sleep based on two sleep scales could predict suicidal ideation in Japanese dayworkers. A longitudinal survey was conducted among 446 Japanese dayworkers working at a company in Japan. Questionnaires were administered in 2013 (baseline) and 2014 (follow-up). To evaluate suicidal ideation, we used Question 19 of the Self-rating Depression Scale, categorizing participants who chose response options "some/a good part/most of the time" as suicidal ideation (+), and those who chose option "never or only a little of the time" as suicidal ideation (-). Two sleep scales, the Pittsburgh Sleep Quality Index (PSQI) and the 3-Dimensional Sleep Scale (3DSS), were selected as potential predictors of suicidal ideation. Only participants who were suicidal ideation (-) at baseline were included in the analysis, and suicidal ideation (+) individuals at follow-up were considered to have developed suicidal ideation during the interval between baseline and follow-up surveys. Data from 293 participants (236 men, 57 women) were analyzed. Twenty-two participants (7.5%) became suicidal ideation (+) at follow-up. Multiple logistic regression analysis showed that only sleep quality of the 3DSS subscale significantly predicted suicidal ideation, even after adjusting for depressive symptoms. That is, assessment of poor sleep did not predict suicidal ideation when based on the PSQI, but did when based on the 3DSS. Assessment of sleep quality based on the 3DSS may prove more useful in predicting worker suicidal ideation in industrial settings with limited facilities than PSQI.

本研究的目的是验证基于两种睡眠量表对睡眠不佳的评估是否能预测日本日工的自杀意念。对在日本一家公司工作的446名日本日工进行了纵向调查。在2013年（基线）和2014年（随访）进行了问卷调查。为了评估自杀意念，我们使用了自评抑郁量表的问题19，将选择“有时/大部分时间”回答选项的参与者归类为有自杀意念（+），将选择“从不或只是偶尔”回答选项的参与者归类为无自杀意念（-）。选择匹兹堡睡眠质量指数（PSQI）和三维睡眠量表（3DSS）这两种睡眠量表作为自杀意念的潜在预测指标。分析仅纳入基线时无自杀意念（-）的参与者，随访时有自杀意念（+）的个体被认为在基线调查和随访调查之间的间隔期出现了自杀意念。对293名参与者（236名男性，57名女性）的数据进行了分析。22名参与者（7.5%）在随访时出现自杀意念（+）。多因素logistic回归分析显示，即使在调整抑郁症状后，只有3DSS子量表的睡眠质量能显著预测自杀意念。也就是说，基于PSQI对睡眠不佳的评估不能预测自杀意念，但基于3DSS时可以。在设施有限的工业环境中，基于3DSS评估睡眠质量可能比PSQI在预测工人自杀意念方面更有用。
