Objective: The purpose of this study was to examine the relationship between child care teachers' emotional intelligence, communicative competence, and job stress. Methods: Four hundred and fifty child care teachers answered questionnaires on three research variables. Data were analyzed by correlation analyses and regression analyses. Results: First, child care teachers' emotional intelligence, i.e. self-emotion appraisal, others' emotion appraisal, uses of emotion, and regulation of emotion, were negatively related to job stress. Second, child care teachers' emotional intelligence, i.e. self-emotion appraisal, others' emotion appraisal, uses of emotion, and regulation of emotion, were positively associated with communicative competence. Third, child care teachers' communicative competence was negatively linked to job stress. Lastly, child care teachers' communicative competence partially mediated the relationship between self-emotion appraisal, others' emotion appraisal, regulation of emotion, and job stress, and child care teachers' communicative competence fully mediated the relationship between uses of emotion and job stress. Conclusion/Implications: This study suggests that high emotional intelligence and effective communication are important in order to reduce child care teachers' job stress.
