Presenteeism among Japanese IT Employees: Personality, Temperament and Character, Job Strain and Workplace Support, and Mental Disturbance

To study correlates of presenteeism among Japanese IT employees, a cross-sectional study in 440 employees of four IT companies was studied with a net-based questionnaire survey. A structural regression analysis revealed that presenteeism (measured by the Work Limitation Questionnaire) was directly associated with common mental symptoms (measured by the Clinical Outcomes in Routine Evaluation-Outcome Measure) and job strain (measured by the Job Strain Questionnaire), common mental symptoms mediated the effects of job strain and poor workplace social support as well as high Harm Avoidance and low Self-directedness and Cooperativeness (measured by the Temperament and Character Inventory-Revised) upon presenteeism. IT company workers presenteeism may be a result of complicated effects of common mental symptoms, job strain and poor workplace social support, and personality traits.
