Translation, Cross-Cultural Adaptation, and Psychometric Evaluation of the Third Version of the Atlanta Heart Failure Knowledge Test.

This study is aimed at translating the third version of the Atlanta Heart Failure Knowledge Test (AHFKTv3) into the Persian language and evaluating its psychometric properties. In this methodological study, the AHFKTv3 was translated into Persian and its face, content, construct validity, and reliability were assessed. The content validity of AHFKTv3 items was >0.78 and the validity of the instrument was 0.96. The standardized factor loading value of all items, except for item 16, was >0.3. The scores of the AHFKTv3 and European Heart Failure Self-Care Behavior Scale had a significant correlation with each other ( < .001). The AHFKTv3 score had a significant relationship with the educational level. The Kuder-Richardson Formula 20 coefficient was 0.908. The Persian AHFKTv3 is a valid and reliable instrument for assessing HF-related knowledge; therefore, it can be used in nursing practice to identify and address the deficits aiming for better patient care and in research to evaluate treatment and .
