What is the DAS?

The DAS is a multidimensional apathy scale, which measured demotivation associated with planning, organisation or attention (Executive apathy),  indifference or emotional neutrality (Emotional apathy) and self-generation of thoughts and/or actions (Initiation apathy).

What is the benefit of using the DAS?

The DAS measures different characteristics of apathy allowing for a deeper understanding of motivational problems.

It was designed to measure demotivation independent of physical disability, which has previously masked problems associated with apathy.

It allows for comparison of self-ratings and informant/carer-ratings to determine if a person is experiencing problems in awareness.

Who can complete the DAS?

The DAS can be completed by the individual about themselves (self-rated version) or by a family member/caregiver/close friend about their observations about the individual (informant/carer-rated version). The DAS can also be administered by researchers and healthcare professionals, both to the individual or their family member/caregiver/close friend.

How long does it take to complete?

The DAS takes approximately 5 minutes to complete.

Has the DAS been validated?

The DAS has been validated in ALS/motor neurone disease, Parkinson’s disease, Multiple Sclerosis and dementia, specifically Alzheimer’s disease. Furthermore is being used in other neurological and psychiatric conditions, such as young onset dementia, stroke and schizophrenia.

Has the DAS been translated to different languages?

The DAS has been, and is in process of being, translated to different languages. If you would like more information and/or to translate the DAS, please contact Dr Ratko Radakovic.
