Validating the short-version European Health Literacy Survey Questionnaire for community-dwelling older adults in Japan.

The European Health Literacy Survey Questionnaire (HLS-EU-Q47) is available in multiple languages, and shortened versions have also been developed. This study aimed to examine the reliability and validity of the short version of the questionnaire (HLS-Q12) developed for community-dwelling older adults in Japan. The HLS-Q12 was developed using 12 of the 47 items of the Japanese version of the HLS-EU-Q47.
