This study was intended to develop the communication competence scale for middle manager in organizations and examine its validity. To develop the communication competence scale of middle managers, first, 632 items were extracted through literature review, expert interview and open surveys for middle managers. In the process of developing the items, it was found that there were differences in competencies between communication with superiors and communication with subordinates. Thus it was decided to develop two different scales for each of middle managers’ communication competencies with superior and communication competencies with subordinate. Based on experts’ evaluations on content validity of the items, 81 items for the communication competencies with superior and 78 items for the communication competencies with subordinates were selected. In the first preliminary survey obtained from 338 middle managers, 10 factors and 69 items were selected for the communication competencies with superior and 8 factors and 54 items were obtained for the communication competencies with subordinate. In second preliminary survey obtained from 206 middle managers, 8 factors and 64 items for the communication competencies with superior and 7 factors and 45 items for the communication competencies with subordinate were obtained. To verify validity of the scale, the total sample was divided into two groups. Exploratory factor analyses were conducted for group 1, and a confirmatory factor analysis was conducted for the other group. The results showed that the exploratory factor analysis extracted 8 factors (persuasion, self-confidence, manner, listening, honesty, confirm, logicality, wisdom) and 52 items for the communication competencies with superior, and 7 factors (listening, humor, emotion regulation, modesty, non-verbal expression, consideration, clarity) and 37 items for the communication competencies with subordinate. In the confirmatory factor analysis using structural equation modeling, the models fit the data well. Also the communication competencies of the middle manager were significantly correlated with the criterion variables such as interpersonal relationship competencies and conflict management, and confirming criterion related validity of the scale. Finally, implications, limitatons and directions for future research were discussed.
