　Although multi-agency collaboration is essential for young carer support, the dimensional structure of inter-organizational social capital (SC) in quasi-governmental agencies remains underexplored. This study therefore aims to develop measurement items for inter-organizational SC between Community Comprehensive Support Centers and their external partner agencies, and to explore its underlying structure. 　Based on the three-dimensional model of Nahapiet and Ghoshal (1998), 14 items were developed and a survey was administered to Center staff in Niigata Prefecture. Exploratory factor analysis extracted a three-factor, 13-item structure that largely corresponded to the theoretical framework. The reliability of each factor was also confirmed. These findings provide a foundation for measuring SC in inter-organizational contexts and offer practical implications for diagnosing and strengthening collaborative arrangements.
