Objective To explore the effect of family support intervention based on social cognitive theory on elderly patients with hypertension.

Methods A total of 96 elderly patients with hypertension were selected as the study subjects, and divided into an observation group and a control group according to the random number table method, with 48 cases in each group.The control group was treated with routine nursing, while the observation group was treated with family support intervention program based on social cognitive theory.The differences of blood pressure, health literacy, self-efficacy, and family support of patients before and after nursing between the two groups were compared.

Results At admission, there were no statistically significant differences in blood pressure, health literacy, self-efficacy, and family support of patients between the two groups (P > 0.05).After 3 months of nursing, the systolic blood pressure and diastolic blood pressure in the observation group were significantly lower than those in the control group (P < 0.01);compared at different time points within the group, the systolic blood pressure and diastolic blood pressure in the two groups at discharge and 3 months after nursing were lower than those at admission (P < 0.05 to P < 0.01);after 3 months of nursing, the systolic blood pressure and diastolic blood pressure in the observation group were lower than those at discharge (P < 0.01).After 3 months of nursing, the total score and each dimension score of health literacy in the observation group were significantly higher than those in the control group (P < 0.01);compared at different time points within the group, the total score and each dimension score of health literacy in the observation group after 3 months of nursing care were significantly higher than those at admission and discharge (P < 0.01), while the total score of health literacy, interactive communication score, and health improvement ability score in the control group after 3 months of nursing care were higher than those at admission (P < 0.05 to P < 0.01).After 3 months of nursing, the total score and each dimension score of self-efficacy in the observation group were higher than those of the control group (P < 0.05 to P < 0.01);compared at different time points within the group, the total score and each dimension score of self-efficacy after 3 months of nursing in the observation group were higher than those at admission (P < 0.05 to P < 0.01), while the total score of self-efficacy, medication status score, and compliance behavior score in the control group after 3 months of nursing were higher than those at admission (P < 0.05).After 3 months of nursing, the level of family support in the observation group was better than that in the control group (P < 0.05).

Conclusions Family support intervention based on social cognitive theory can significantly improve patients' health literacy, self-efficacy and family support, and plays an important role in reducing blood pressure.
