This survey research aimed to study the VHVs’ core competencies, in particular by analyzing the VHVs’ Competency Standards developed in 2007 in Thailand. The research used multistage probability random sampling. A total of 500 samples were collected from four regions in country through administering a questionnaire. The IOC was 0.70 –1, the CVI was 1, and the Cronbach’s alpha coefficient was 0.98. Exploratory factor analysis was deployed with principal component analysis and the Promax method for factor extraction and rotation. The sampling adequacy was verified with appropriate values (KMO = 0.96 and MSA values for each item ranging from 0.94 - 0.98 and Bartlett’s Test of Sphericity (p < 0.001)). The results demonstrated that there are seven core competencies for VHVs as follows: 1) Empowering children and youth to engage in community healthcare development, 2) Health promotion, 3) Disease prevention, 4) Basic medical care, 5) Policy implementation, 6) Fostering self-care awareness, and 7) Health risk monitoring and precaution. All competencies explained 70.02% of the variance. The results could serve as guidelines for developing VHVs’ competencies to deliver high-quality healthcare services in the community.
