[SUMMARY] This study aimed to examine the internal validity, efficiency, and practicality of “the collaborative model to promote community health promotion through the empowerment of community health workers.” Specifically, the model’s ability to explain the actual collaboration between PHN and CHWs, its efficiency in collaborating and evaluating empowerment, and specific support measures based on it were examined by collating with practical experience. About four skilled health nurses were asked to review the model’s internal validity, and three PHNs in charge of CHW development cooperated with two to four CHWs from three different centers and were in charge of evaluating the efficiency and practicality of the model. A guide consisting of a model and a checklist was prepared and sent to the subjects in advance, and based on this, individual interviews with PHNs and group interviews with CHWs were conducted and analyzed qualitatively and inductively. The elements of the model and the opinions based on the actual cases of the subjects agreed, and the content was generally valid. The model can be used in practice, and it is useful for PHNs and CHW to appropriately evaluate activities and obtain suggestions for solving problems. It also contributed to improving motivation for activities by confirming that it was done. By applying this model, we believe that the collaboration and empowerment of PHNs and CHWs will be deepened and developed in a mutually related manner, which will contribute to the promotion of community health promotion led by residents.
