Background and Objective: Hypertension represents a major global public health concern and remains a leading contributor to mortality and disability worldwide. Considering the high prevalence of hypertension in Qaen and the insufficient level of public awareness, this study aimed to evaluate the effectiveness of an educational intervention based on the Precaution Adoption Process Model (PAPM) in promoting hypertension preventive behaviors among adults aged 30–59 years in this region.

Materials and Methods: This randomized controlled quasi experimental study was conducted during 2025 among 160 residents of Qaen aged 30–59 years. Participants were selected using systematic random sampling and were randomly allocated to either an intervention or a control group (n=80 per group). The intervention group received an educational program delivered in five sessions, each lasting 30–45 minutes. Data were collected using a structured questionnaire comprising demographic characteristics, knowledge items, and constructs related to the PAPM. Participants were assessed at three time points: before the intervention, immediately after the intervention, and three months post intervention. Data analysis was performed using SPSS (version 23). Independent t tests, repeated measures ANOVA, and chi square tests were employed, with the level of statistical significance set at p<0.05.

Results: The educational intervention based on the PAPM led to a statistically significant increase in the mean scores of knowledge, perceived susceptibility, perceived severity, perceived benefits, self efficacy, cues to action, and preventive behaviors immediately after the intervention and three months later (p < 0.001). Moreover, a significant reduction was observed in the mean score of perceived barriers, while no significant changes were found in the control group.

Conclusion: The PAPM based educational intervention effectively improved participants’ knowledge, attitudes, and preventive behaviors related to hypertension, suggesting that incorporating this model into community based educational programs can be an effective strategy for promoting health enhancing behaviors and reducing the prevalence of hypertension.
