Development of the Japanese Version of the Brief Dimensional Apathy Scale (b‐J‐ <scp>DAS</scp> ): Multidimensional Apathy in Dementia

The present findings suggest that the b-J-DAS, which requires caregivers to assess patient apathy, is a suitable multidimensional apathy scale with acceptable reliability and validity. However, further studies on the influence of caregiver-related factors are required.
