Hypertension Knowledge Test: Development and Validation

Abstract

This paper discusses the process of development and validation of Hypertension Knowledge Test on a total sample of 614 hypertensive patients recruited in three stages. Standard procedure of test development was followed. The final form of the test consisted of 22 items hierarchically arranged following the criteria of item difficulty and item discrimination. The test measures four dimensions of knowledge viz. General awareness, Lifestyle, Causes, Care, Casualty awareness and Management of medication. The test–retest reliability was 0.92 (p<.001).The construct validity measured by correlating hypertension knowledge scores with Blood Pressure readings was highly significant (p<0.01).
