Development of a shortened version of the teacher-rated Teamwork Inventory for Community-Based School Management

Abstract

In order to promote research on school-community collaboration, there is a need to develop a scale that succinctly measures such collaboration. The present study developed a shortened version of the Teamwork Inventory for Community-based School Management (TICSM) for teachers. A web-based survey was administered to teachers in public elementary and junior high schools. Confirmatory factor analysis confirmed a three-factor structure of the TICSM for teachers. A total of 14 items were deleted to shorten the TICSM for teachers. Then, a confirmatory factor analysis was conducted again to test the model fit. To confirm measurement invariance in elementary and junior high schools, a multiple population confirmatory factor analysis was conducted, and the sufficient model fit of the scalar invariance model was confirmed. Criterion-related validity was confirmed in relation to group identification as a teacher group, workplace climate, trust in parents and community members, and positive attitude toward anchor point activities.
