PresentationForming strong interpersonal relationships enables an organization or individual to achieve more favorable outcomes. The objectives of this study were to examine the frequency of interpersonal interactions among safety professionals (SPs) employed at Taiwanese universities and the factors that affected this frequency. To accomplish these objectives, we mailed questionnaires to a simple random sampling of 200 university SPs. Moreover, an interpersonal relationship scale was developed in this study; exploratory factor and internal consistency analyses revealed that the scale was valid and reliable. Results derived from the questionnaire revealed that in SP interpersonal relationships, general affairs department personnel, laboratory or internship unit supervisors, and teaching staff ranked highest in frequency of interactions. Multivariate analysis of variance results showed that establishing a safety department exerted a statistically significant effect on SP interpersonal relationships. SPs employed by universities with safety departments interacted more frequently with both internal and external relationships. Therefore, we suggest that universities without a safety department establish such a department to strengthen the labor safety and health structure, thereby benefitting SPs in fulfilling responsibilities to promote safety and health management
