This study uses the outreach personnel who perform boundary spanning activities from the Bureau of Employment and Vocational Training and the self-developed but validated East-West Personal Scale (EWPS) based on the Chinese area. The EWPS scale covers three domains and 11 overall categories. The first domain is task which includes objective management, time management, quality request, and information processing. The second domain is interpersonal relationship, and social skills, self-adjustment, and affiliation needs are the three categories. Self-psychology, the third domain, has four categories covering positive attitude, no sense of conflict, no sense of rejection, and social support. In order to evaluate the importance of these three domains and 11 categories, thirteen executive decision makers were participated and decision making trial and evaluation laboratory (DEMATEL) is used as a tool to compute the importance and structural relationships of domains and categories. The results show that self-psychology is the main domain to be considered for boundaryspanners because of a net receiver and influencing interpersonal relationships directly without being affected by the other domains. Moreover, positive attitude is the most important category under selfpsychology.
