Abstract

BACKGROUND: How to help workers establish a safe and healthy working environment is the primary purpose of promoting workplace health psychology. OBJECTIVE: The aim of this study was to investigate the relationship between interpersonal resources and job performance (work performance, organizational citizen behavior). Besides, this study tries to clarify the psychological mechanisms of vitality and emotional attachment, and further considers the moderating role of group harmony. METHODS: Questionnaires were used. Two samples included 267 and 285 questionnaires were collected in study 1. A total of 151 valid and matched surveys were collected in study 2. RESULTS: Study 1 tested the psychometric properties of the interpersonal resources scale, and then, established three constructs of interpersonal resources: “interpersonal caring”, “interpersonal inclusion”, and “interpersonal connection”. Study 2 results showed positive correlations between interpersonal resources and job performance. Vitality has the mediating effect between interpersonal resources and work performance, and emotional attachment has the mediating effect between interpersonal resources and organizational citizen behaviors. In addition, the moderating effects of group harmony were supported. CONCLUSION: This research covered two studies to clarify the construct of interpersonal resources and develop an interpersonal resources scale with reliability and validity. Furthermore, this research further discussed the theoretical meaning and practical application and explained the future research direction. This research not only responds to experts’ calls but also considers the influence of cultural values to examine the model of interpersonal resources.
