Developing and Validating the Japanese Version of the Essentialist Beliefs About Ageing Scale: The Otassha Study
The EBA-J scale demonstrated a reliable two-factor structure with acceptable internal consistency. Its associations with subjective health and subjective age bias, which were small yet meaningful, provided initial evidence of criterion validity. Overall, the scale is useful for measuring beliefs regarding ageing in Japan, supporting cross-cultural studies of ageing perceptions.
