Key result
Common-Sense Model education improves most illness perception subscales compared to routine care.
Why the study?
Limited research has examined hypertension management from the patient's perspective, particularly the effect of education based on the Common-Sense Model on illness perception among older adults with hypertension.

Does an educational program based on the Common-Sense Model improve illness perception in older adults with primary hypertension?
p-value: p=<0.05
A Common-Sense Model-based educational program significantly improves multiple cognitive dimensions of illness perception in older adults with hypertension.
May enhance cognitive illness perceptions in older adults with hypertension; extends Common-Sense Model evidence but leaves emotional domains unaddressed and requires larger trials.
Objectives: Effective blood pressure management requires sustained medication adherence and health-related behavior change. However, limited research has examined hypertension management from the patient's perspective. This study aimed to evaluate the effect of an educational program based on the Common-Sense Model (CSM) on illness perception among older adults with hypertension. Methods: This randomized controlled clinical trial included 62 patients with hypertension who were referred to Khalil-Azad Health Center in Larestan, Iran, from March to July 2024. Participants were selected and randomly assigned to the intervention group (n = 31) or control group (n = 31). The intervention group participated in a CSM-based educational program consisting of five 45-60-minute sessions over 1 month, whereas the control group received routine care only. Participants completed the Brief Illness Perception Questionnaire before the intervention and 8 weeks after the start of the intervention. Results: Before the intervention, illness perception subscale scores did not differ significantly between the intervention and control groups (P > 0.05). After the intervention, illness perception subscale scores improved in the intervention group compared with the control group, except for illness consequences, illness concern, and emotional representation (P < 0.05 for the remaining subscales). Conclusions: A CSM-based educational program may help nurses and health care providers improve illness perception among patients with primary hypertension.

Hamidizadeh et al. (2026) conducted an RCT in Primary hypertension (n=62). Educational program based on the Common-Sense Model (CSM) vs. Routine care only was evaluated on Illness perception (Brief Illness Perception Questionnaire subscale scores) (p=<0.05). An educational program based on the Common-Sense Model significantly improved most illness perception subscales (P<0.05) compared to routine care, although it did not improve illness consequences, illness concern, or emotional representation.
