OBJECTIVES: Hypertension is one of the most common chronic diseases worldwide and represents a significant public health issue, as well as a serious economic burden. The aim of our research was to adapt the Hypertension Knowledge Test (HKT), which assesses disease-specific knowledge, and the QLICD-HY quality of life questionnaire into Hungarian, and to evaluate their reliability. A further objective was to examine the correlations between socio-demographic factors, blood pressure values, physical activity, and quality of life in relation to disease-specific knowledge among individuals with hypertension.
METHODS: A total of 217 individuals diagnosed with hypertension, aged between 40 and 65, participated in our study. The Hungarian adaptation of the questionnaires followed Beaton's six-step guideline. Statistical analyses included descriptive statistics, analysis of variance (ANOVA), Cronbach's alpha coefficients, and Spearman’s correlation coefficients to assess external validity and test-retest reliability.
RESULTS: The Cronbach’s alpha coefficient for the HKT was 0.833, and for the QLICD-HY, it was 0.856, indicating good internal consistency. The intraclass correlation coefficient (ICC) values obtained during the test-retest were 0.999 for the HKT and 1.000 for the QLICD-HY, demonstrating excellent reliability. The average score for disease-specific knowledge was 13.08 ± 4.67 out of a possible 21 points. No significant correlation was found between disease-specific knowledge and physical activity. However, a positive and significant correlation was observed between knowledge about hypertension and quality of life (p < 0.001). While no significant association was found between hypertension-specific quality of life and physical activity performed at work, significant correlations were identified with active transportation and both moderate and vigorous recreational activities (p < 0.05).
CONCLUSIONS: Based on our findings and supported by international literature, the Hungarian versions of the HKT and QLICD-HY questionnaires are reliable and applicable tools for assessing disease-specific knowledge and quality of life in individuals with hypertension.
