Behavioral Modification, Health Volunteers Buddies, Uncontrolled HypertensionAbstract
This quasi-experimental research, employing a two-group pretest-posttest design to investigate the effectiveness of an intensive behavior modification program, implemented with Health Volunteers Buddies, among patients with uncontrolled hypertension. The study was conducted at the Urban Community Health Center under the Surat Thani Provincial Administrative Organization. The sample consisted of 54 patients diagnosed by doctors with hypertension (blood pressure exceeding 140/90 mmHg for at least 6 months). The sample size was calculated using the Two Independent Means formula via the N4 studies application. Participants were selected by purposive sampling and assigned to an experimental group (n=27) and a control group (n=27). Research instruments included: an intensive behavior modification program (based on the 3E. 2S. principles), a knowledge and self-care behavior questionnaire. Content validity was verified by three experts (IOC = 1.00). The reliability of the knowledge questionnaire yielded a coefficient of 0.80. The self-care behavior questionnaire yielded Cronbach’s alpha coefficients of .82, respectively. Data were analyzed using descriptive statistics, Paired t-test, and independent t-test.
The results revealed that after the intervention, the experimental group showed significantly higher mean scores for knowledge and self-care behaviors, and significantly lower mean systolic and diastolic blood pressure levels compared to the pre-intervention phase (p< .001). When comparing between the groups, the experimental group demonstrated significantly better knowledge, self-care practices, and blood pressure control than the control group (p< .001).
The findings of this study suggest that this intensive behavior modification program can serve as a guideline for health care personnel at all levels of non-communicable disease (NCD) services. It can be adapted into care activities to enhance patients' knowledge, understanding, and ability to self-manage their disease correctly.
