Background: The family, as the smallest social institution, has responsibilities across many functions, including maintaining family health. Increases in chronic diseases and life expectancy require more family support to prevent disease and implement treatment for family members with chronic diseases. Therefore, physician involvement in not only the treatment of diseases but also their prevention and rehabilitation is required In Indonesia. Hence, a new approach for physician involvement with families is required, especially with regard to comprehensiveness. This study aimed to develop a physician involvement program with the family model for primary healthcare in Indonesia. Methods: A two-round Delphi method with family medicine experts from 17 of the highest accredited medical faculties in Indonesia as participants was conducted, and factor analysis performed thereafter. The items were considered relevant at ≤0.8 validity content ratio. The second step of this research is survey using e-questionnaire involving 101 primary care physician from all over Indonesia. They live scattered in several provinces in the main islands of Indonesia such Sumatra, Java, Kalimantan, Sulawesi dan Bali. Results: Results showed an adequately measured sample and correlation for all items (Kaiser-Meyer-Olkin of sampling=0.821; Bartlett’s test <0.001). Seven dimensions were derived from results with eigenvalue of >1, and 25 items were filtered after determining the loading factor of >0.5. The Cronbach’s α for each factor varied from 0.602 to 0.829, and that for the total 25 items was 0.913, with a total variation documented as high as 66%. Conclusion A new physician involvement model with the family approach model, known as the “GENOGRAM model,” was developed, which consisted of seven dimensions and 25 items.
