Main purposes of this study were to examine pattern of social network structures and to investigate the network properties ; namely Centralization, Social cohesiveness, and Actor centralities . Two specific pattern of social relations ; Information exchange network and Instrumental network, were also examined. Social network data were collected through the dyadic relationship questionnaire and analyzed by UCINET version 6.158 whereas Netdraw version 2.055 was applied to visualize pattern of the social network structures. According to the Social Network Analysis q SNA , the over all network has been found in 2 main network features. Firstly , All channel network , which every individual actors were found directly interacted with each other around the network in order to sending as well as receiving health messages in loose knit manner. Secondly , Tree network , which most of supports for the whole network came from the core group whereas all sub-groups were tied in weak and strong ties.
