Outline of Final Research Achievements

Using longitudinal data of five measurements in the present study, we applied a linear mixed-effects model with presenteeism (measured by labor productivity) as the dependent variable and factors known to have influence on presenteeism as predictor variables. In the univariate analyses, some factors revealed a significant association but the significance disappeared in the multivariate analysis, except for depression/anxiety and nicotine dependence. Ultimately, in the mediation analysis we confirmed that work-place bullying has an influence on labor productivity via depression/anxiety as a causal relationship between each variable. This study revealed the significant role of work-place bullying from the perspective of labor productivity.

Academic Significance and Societal Importance of the Research Achievements

本研究で初めて，職場のいじめは，抑うつ・不安を通じて病気出勤に影響することを実証することができた．2020年より職場でのパワーハラスメント防止措置を事業主に義務付ける改正労働施策総合推進法が施行されたが，コンプライアンスの観点からだけではなく，労働生産性の観点からみても，労働者の心の健康の観点からも，職場のいじめをなくす取り組みの意義は大きい．
