BACKGROUND: Nurses’ knowledge and Experience with Health Literacy can affect the treatment
process, improving the quality of health care and effectively communicating with all clients. Evaluation
of nurses’ knowledge and experience requires a reliable instrument. This study aimed to translate
cross‑cultural adaptation and testing of Health Literacy Knowledge and Experience Survey (HL‑KES).
MATERIALS AND METHODS: This cross‑sectional methodological study was done during 2018–2019.
The study was carried out in two stages: the first phase was designed to obtain a translation and
cross‑cultural equivalent of the (HL‑KES), based on the World Health Organization (2018) and the
Sousa and Rojjanasrirat (2011) Guidelines in six steps: preparation, forward translation, reconciliation,
back translation, back translation review and pretesting and cognitive debriefing of the translated
questionnaires. The second phase was conducted to evaluate the psychometric properties of the
RESULTS: The content validity index and content validity ratio values of all items were >0.62 and
0.79, respectively. Based on the Kuder–Richardson formula, the reliability of the knowledge dimension
was reported as 0.7. Furthermore, split‑half coefficient for inter‑rather reliability and test–retest were
0.76 and 0.96, respectively. The reliability of their experiences with the HL‑KES was measured using
Cronbach’s alpha, in which it was 0.82.
CONCLUSIONS: The Persian version of the instrument for assessing nurses’ knowledge and
experience with health literacy had good validity and reliability. It is recommended that it should be
used in educational, clinical environments, and also in future research studies.
