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

Background and Purpose: 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. Methods: In this methodological study, the AHFKTv3 was translated into Persian and its face, content, construct validity, and reliability were assessed. Results: 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 (p < .001). The AHFKTv3 score had a significant relationship with the educational level. The Kuder-Richardson Formula 20 coefficient was 0.908. Conclusion: 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 healthcare programs.
