Effect on Self-efficacy Perception to Hypertension Disease Prevention among People with Pre-Hypertension in Rhonphibul Sub-district, Rhonphibul District, Nakhon Si Thammarat Province

Abstract

This research aimed to study the effect of self-efficacy to prevent hypertension disease among people with pre-hypertension in Rhonphibul Sub-district, Rhonphibul District, Nakhon Si Thammarat Province. The study was a quasi experiment, one group pretest–posttest design. The studied samples were pre-hypertension group who had blood pressure level between 120-139/80-89 mmHg, and selected by simple random sampling technique from village number 2, Rhonphibul Sub-district consisting of 30 pre-hypertension cases. The samples were screened with verbal screening form before participating in the program again. Data collection was perform with self-administered questionnaires, and were analyzed by paired sample t–test. The results revealed that, after the intervention, the pre-hypertension group had perceived self-efficacy score was higher than that before intervention with the Mean=28.80, SD=1.540, compred to Mean=22.73, SD=2.840) before the intervention (p<0.001). They also had higher perceived outcome expectancy on having proper behavior than that before the intervention (Mean=28.23, SD=1.612 vs Mean=22.63, SD=4.140) (p<0.001). Furthermore, the mean score on disease preventing behaviors after intervention (Mean=52.67, SD=5.616) was also significantly higher than before intervention (Mean=42.30, SD=5.908) (p<0.001. At the end of the program, 28 of the samples had optimal blood pressure <120 and <80 were 28 samples and only 2 samples had normal blood pressure at normal level 120-129 and/or 80/84. This study suggested that developing self-efficacy affects behavioral modification; and thus these activities should be applied for other chronic patients as well.
