Main Article Content
Abstract
The purpose of this quasi-experimental, pre- and post-experimental study was to determine the effect of self-efficacy enhancement program using LINE application on blood pressure levels among persons with hypertension. The sample consisted of 56 hypertension patients aged 40 years and older, both male and female who received antihypertensive medication at outpatients clinic of at King Chulalongkorn Memorial Hospital. The control group (n = 28) and experimental group (n = 28) were matched by gender, age, and type of medication. The experimental group attended the eight-week self-efficacy enhancement program using LINE application focusing on blood pressure level, while the control group received conventional care. The instruments used for collecting data were the socio-demographic questionnaire and blood pressure levels, and the experimental control instrument was the health behavior record form with Cronbach’s alpha coefficient of 0.85. Data were analyzed using descriptive statistics and t-test with significance level at .05. The results revealed that the mean scores of systolic and diastolic blood pressure level among persons with hypertension after attending the program were significantly lower than before attending the program (t = 4.75, df = 27, p < .05; t = 2.54, df = 27, p < .05). The mean score of systolic and diastolic blood pressure in experimental group who attended the program were significantly lower than the control group (t = 3.24, df = 54, p < .05, t = 2.77, df = 54, p < .05).
