title: Organizational justice and major depressive episodes in Japanese employees: a cross-sectional study.
abstract: OBJECTIVE
  Several European studies showed that low organizational justice (i.e., procedural justice and interactional justice) was associated with major depressive disorders. In these studies, however, the diagnosis of major depressive disorders may be underestimated because they identified only individuals who visited a doctor and received a diagnosis. Moreover, these studies did not consider neurotic personality traits, which can affect the occurrence of major depressive disorders. The purpose of the present study was to investigate the cross-sectional association of organizational justice with major depressive episodes in the past 12 months more precisely in Japanese employees.
  
  
  METHODS
  A total of 425 males and 708 females from five branches of a manufacturing company in Japan completed self-administered questionnaires measuring organizational justice, other job stressors (i.e., job strain, social support at work, and effort-reward imbalance), neuroticism, and demographic characteristics. A web-based self-administered version of the computerized Composite International Diagnostic Interview Version 3.0 (CIDI 3.0) was used to assess major depressive episodes. Logistic regression analyses were conducted.
  
  
  RESULTS
  In the univariate analysis, low procedural justice and low interactional justice were significantly associated with major depressive episodes in the past 12 months. After adjusting for other job stressors and demographic characteristics, only the association of interactional justice remained significant. The moderating effect of neuroticism on the association of organizational justice with major depressive episodes in the past 12 months was not significant.
  
  
  CONCLUSIONS
  Low interactional justice may be associated with major depressive disorders regardless or other job stressors or neurotic personality traits.
