The brief Dimensional Apathy Scale (b-DAS) has recently been published in Journal The Clinical Neuropsychologist and the paper can be found here. This is a quick and comprehensive informant/carer-based tool for assessment of apathy subtypes in clinical and research settings, with published clinical cutoffs.
The b-DAS is now also available on the website and can be downloaded, along with ‘Frequent Asked Questions’, on the b-DAS page.
