    ABSTRACT: Previous European studies reporting low procedural justice and low interactional justice were associated with increased health problems have used a modified version of the Moorman's Organizational Justice Questionnaire (OJQ, Elovainio et al., 2002) to assess organizational justice. We translated the modified OJQ into the Japanese language and examined the internal consistency reliability, and factor-based and construct validity of this measure. A back-translation procedure confirmed that the translation was appropriate, pending a minor revision. A total of 185 men and 58 women at a manufacturing factory in Japan were surveyed using a mailed questionnaire including the OJQ and other job stressors. Cronbach alpha coefficients of the two OJQ subscales were high (0.85-0.94) for both sexes. The hypothesized two factors (i.e., procedural justice and interactional justice) were extracted by the factor analysis for men; for women, procedural justice was further split into two separate dimensions supporting a three- rather than two-factor structure. Convergent validity was supported by expected correlations of the OJQ with job control, supervisor support, effort-reward imbalance, and job future ambiguity in particular among the men. The present study shows that the Japanese version of the OJQ has acceptable levels of reliability and validity at least for male employees.

    ABSTRACT: This study aimed to analyze if adverse psychosocial working conditions, defined by the model of effort-reward imbalance (ERI), increase the risk of sleep disturbances in the Danish workforce. Analyses were conducted both cross-sectionally and prospectively in a representative sample of Danish employees. The cross-sectional sample included 2614 participants (50% women) aged 18-59 years, of whom 263 had sleep disturbances. Of the 2351 participants initially free of sleep disturbances, 304 (12.9%) developed sleep disturbances during the 5-year follow-up. Data were analyzed with gender-stratified, multivariate logistic and linear regression analyses, adjusted for numerous covariates. Cross-sectionally, a 1 S.D. increase in the ERI ratio was associated with sleep disturbances among both men [odds ratio (OR)=1.65, 95% confidence interval (CI)=1.20-2.27] and women (OR=1.82, 95% CI=1.46-2.28). In the prospective analysis, a 1 S.D. increase of the ERI ratio at baseline predicted the onset of sleep disturbances among men (OR=1.39, 95% CI=1.03-1.87) but not among women (OR=0.97, 95% CI=0.76-1.24). Among men, ERI is a risk factor for the development of sleep disturbances in the Danish workforce. Among women, an association between ERI and sleep disturbances was restricted to the cross-sectional sample. Improving psychosocial working conditions might reduce the risk of sleep disturbances and subsequently also help to prevent clinical disorders related to sleep disturbances.
