Abstract Objective: Apathy is a prominent syndrome across neurodegenerative diseases. The Dimensional Apathy Scale (DAS) assesses three apathy subtypes—executive, emotional, and initiation—and is sensitive and valid in amyotrophic lateral sclerosis (ALS), Alzheimer’s disease (AD), and Parkinson’s disease. This study describes the development of the brief DAS (b-DAS), which will enable apathy to be swiftly detected in the clinic. Method: 102 ALS and 102 AD patients’ previously collected data… Expand
Reliability and validity of the brief dimensional apathy scale.
The b-DAS is a fast, reliable, and valid instrument for screening apathy subtypes independent of physical disability and shows good internal consistency, excellent test-retest reliability, and significant positive correlation with the original DAS. Expand
Clinical significance of self-descriptive apathy assessment in patients with neurological form of Wilson’s disease
Methods relying on self-description appear inferior to informant-based scales when diagnosing apathy and more objective criteria and measurement tools are needed to better understand this clinical syndrome. Expand
Spanish Adaptation of the Dimensional Apathy Scale (DAS) in Amyotrophic Lateral Sclerosis
The Spanish translation of the DAS is valid and reliable for use in assessing multidimensional apathy in the Spanish population and will allow for future research to explore different apathy subtypes and their impact in ALS and other conditions. Expand
Apathy Measures in Older Adults and People with Dementia: A Systematic Review of Measurement Properties Using the COSMIN Methodology
The Apathy Evaluation Scale (AES) and Lille Apathy Rating Scale (LARS) had sufficient content validity, reliability, construct validity, and where applicable, structural validity and internal consistency and are recommended for measuring apathy in older adults and people living with dementia.

Apathy in amyotrophic lateral sclerosis: insights from Dimensional Apathy Scale
The DAS is a valid screening tool for apathy and its aspects in ALS through limiting the impact of physical disability and exploring the psychometric properties, the sensitivity and the specificity of the Dimensional Apathy Scale (DAS) as a screening tool. Expand
Developing a new apathy measurement scale: Dimensional Apathy Scale
The DAS is a well-constructed method for assessing multidimensional apathy suitable for application to investigate this syndrome in different disease pathologies. Expand
Multidimensional apathy in ALS: validation of the Dimensional Apathy Scale
Apathy in ALS is characterised by a specific profile of increased initiation apathy and reduced emotional apathy, and the new Dimensional Apathy Scale (DAS) is a reliable and valid measure for the assessment of multidimensional apathy. Expand
A Novel Assessment and Profiling of Multidimensional Apathy in Alzheimer's Disease.
The DAS is a psychometrically robust method of assessing multidimensional apathy in AD, and the apathy profiles in AD are heterogeneous, with additional specific impairments relating to awareness dependent on apathy subtype. Expand
Assessment of apathy minimising the effect of motor dysfunctions in Parkinson’s disease: a validation study of the dimensional apathy scale
The DAS is a valid and reliable tool to assess multidimensional apathy in PD, independently of severity of motor symptoms and good evidence for convergent and discriminant validity. Expand
A prospective longitudinal study of apathy in Alzheimer’s disease
Apathy in AD is a behavioural marker of a more aggressive dementia, characterised by a faster progression of cognitive, functional, and emotional impairment. Expand
Multidimensional apathy and executive dysfunction in amyotrophic lateral sclerosis
This is the first study to show specific associations between apathy subtypes (Emotional and Initiation) and executive and emotional cognitive dysfunction, indicating possible distinct underlying mechanisms to these demotivational symptoms. Expand
Different aspects of emotional processes in apathy: Application of the French translated dimensional apathy scale
Apathy is a behavioural symptom that occurs in neuropsychiatric, neurological and neurodegenerative disease. It is defined as a lack of motivation and/or a quantitative reduction of goal-directedExpand
Reliability and validity of the apathy evaluation scale
Evidence for the reliability and construct validity of the Apathy Evaluation Scale is presented and guidelines for the administration of the AES are presented, along with suggestions for potential applications of the scale to clinical and research questions. Expand
Apathy in dementia: an examination of the psychometric properties of the apathy evaluation scale.
