Previous studies have shown the positive effects of collective efficacy on community collective actions. As a predictor of collective efficacy, while behavioral social connectedness has shown a positive effect in some studies, the effect of cognitive social connectedness is little known. In this study, the perceived intragroup relationship (Yuki, 2003) was applied in order to investigate the relation among perceived intragroup relationship, collective efficacy, and the intention of participating in community development. We distributed questionnaires to 500 citizens and analyzed data that were collected from 121 respondents. The result of correlation analysis showed a positive relation among the intention of participating, collective efficacy, intragroup relational cognition, and behavioral social connectedness. Furthermore, a determinate process model of the intention to participate was examined using path analysis. The results indicate that perceived intragroup relationship has a positive correlation with social connectedness behavior and a positive effect on collective efficacy, but social connectedness behavior does not have a significant effect on collective efficacy.
