Translation and validation of the Greek version of the hypertension knowledge‐level scale

Aims and objectives To translate and validate a Greek version of the Hypertension Knowledge‐Level Scale. Background The major barrier in the management of hypertension is the lack of adherence to medications and lifestyle adjustments. Patients' knowledge of the nature of hypertension and cardiovascular risk factors is a significant factor affecting individuals' adherence. However, few instruments have been developed to assess patients' knowledge level and no one has been translated into Greek. Design This study used a case control study design. Methods Data collection for this research occurred between February 7, 2013 and March 10, 2013. The sample included both hypertensives and non‐hypertensives. Participants simultaneously completed the version of the Hypertension Knowledge‐Level Scale. A total of 68 individuals completed the questionnaire. Results Coefficient alpha was 0·66 for hypertensives and 0·79 for non‐hypertensives. Τhe difference for the mean scores in the entire scale between the two samples was statistically significant. In addition, significant differences were observed in many sub‐dimensions and no correlation was found between level, knowledge and age, gender and education level. Conclusions Findings provide support for the validity of the Greek version of the Hypertension Knowledge‐Level Scale. Relevance to clinical practice The translation and validation of an instrument evaluating the level of knowledge of hypertension contribute to assessing the provided educational intervention. Low knowledge level should lead to the development of new methods of education, therefore nurses will have the opportunity to amplify their role in patients' education and develop relationships based on honesty and respect.
