Workers living with mental health illnesses are increasing due to job stress. Previous studies have identified intra-organizational communication as one of the job stressors. This study examined the correlation between intra-organizational communication and mental health illnesses in the workplace. Participants were recruited from Corporation A (N=283). Team Communication Interface Questionnaire (TCIQ) and Kessler 6 Scale (K6) were used to measure intra-organizational communication and mental health illnesses, respectively. TCIQ was used due to having good psychometric properties and for its unique ability to gauge each member’s impressions about their team. Results of the Pearson correlation coefficient indicated that there was a significant negative association between K6 score and total TCIQ score (R=-0.321, P<0.01). The correlation coefficients also reported significant negative associations (P<0.01) between K6 score and each item of TCIQ: mission recognition (-.280), information transmission (-.275), schedule management (-.284), and evaluation awareness (-.227). The results show that intra-organizational communication is related to mental health illnesses. Examining intra-organizational communication through TCIQ in the workplace may promote mental health and help achieve organizational goals more effectively.
