The purpose of this study is to investigate factors associated with inter-organizational linkages of community coalitions through examine community operation process, organization structures, and members’ attitudes. It not only intends to understand the community organizing status in Taiwan but also to thoroughly investigate significant factors that are associated with inter-organizational linkages of community organizations and the expansion of community coalitions. A cross-sectional study design was adopted in the present study. Stratified random sampling was used to derive the sample for this study. The study population was defined as the 41 centers for community health development in Northern Taiwan. Study participants were recruited from members of 20 centers randomly selected from the 41 centers. A total of 565 structured questionnaires were mailed out to participants and 358 questionnaires were returned, yielding a response rate of 63.4%. Important findings include: (1)In the dimension of operational process, communication and community participation and benefits were positively associated with the extent of inter-organizational linkages. (2)In the dimension of organization structure, organization administrative operation was positively associated with the extent of inter-organizational linkages and the expansion of community coalitions. (3)Organization administrative operation, member satisfaction, organizational climate, and capacity building of members were significant predictors of inter-organization linkages of community, accounting for 19 percent of total variation. Organization administrative operation alone explained 13 percent of total variation. (4)Organization administrative operation, member satisfaction, organizational climate, and capacity building alone members were significant predictors of the expansion of community coalitions, accounting for 16 percent of total variation. Organization administrative operation alone explained 12 percent of total variation. We propose a number of recommendations based on the research findings for the reference of health departments and related sectors in promoting inter-organizational linkages of community and the expansion of community coalitions: (1)strengthening community organization administrative functions to integrate community resources; (2)augmenting organization division of community building center and encouraging every position in the community center to fully play its role; (3)improving communication within the organization; (4)appropriate paid staff hours and building good organizational climate.
