Abstract: Objective To construct a health-related behavior intervention program based on Fogg behavior model and to explore its application effect. Methods A research team was established to consult relevant literature, construct a health-related behavioral intervention program for elderly patients with cirrhosis based on Fogg behavior model, and 152 elderly patients with cirrhosis were selected to carry out a randomized controlled study to explore its application effect. Results After 2 rounds of letter inquiry, a health-related behavior intervention program based on Fogg behavior model was formed, including 10 intervention items in 3 intervention stages. The Cr value of the two rounds of expert correspondence letters was 0.895 and 0.930, respectively. The application results showed that after the intervention, the self-management behavior score in the study group was 82.19±8.97, compared with 74.16±9.86 in the control group (P<0.05), and the self-efficacy score in the study group was 32.87±3.28, compared with 28.43±5.11 in the control group (P<0.05). Conclusions The health-related behavior intervention program based on Fogg behavior model can significantly improve patients’ self-management behavior and self-efficacy.
