The Dimensional Apathy Scale (DAS) is widely used to assess these domains, yet no validated German version has been available. This study aimed to translate and validate the German DAS (G\u2010DAS) in control participants (HC) and to characterize apathy profiles in German\u2010speaking people with amyotrophic lateral sclerosis (pwALS). Seventy\u2010seven HC and 32 pwALS completed self\u2010rated and caregiver\u2010rated measures of apathy, depression, disinhibition and executive dysfunction. The G\u2010DAS was translated using a multi\u2010round back\u2010translation procedure. Psychometric validation was undertaken in the HC cohort. A subsample of HC matched to pwALS on age and sex was used for between\u2010group comparisons and for deriving exploratory reference thresholds. The G\u2010DAS demonstrated good to high internal consistency across subscales (\n                    <jats:italic>\u03b1<\/jats:italic>\n                    \u2009=\u2009.76\u2013.85) and total scores (self\u2010rated:\n                    <jats:italic>\u03b1<\/jats:italic>\n                    \u2009=\u2009.88; caregiver\u2010rated:\n                    <jats:italic>\u03b1<\/jats:italic>\n                    \u2009=\u2009.86). Convergent validity was supported by significant correlations with the Apathy Evaluation Scale and Frontal Systems Behavior subscales, particularly for the Initiation and Executive subscales. Divergent validity was evidenced by the absence of associations with anxiety and depression. PwALS showed significantly higher Executive and Initiation apathy compared with matched HC, whereas Emotional apathy did not differ. Exploratory threshold scores derived from matched HC indicated that up to 47% of pwALS exhibited clinically elevated Initiation apathy. The G\u2010DAS is a reliable and valid German\u2010language measure of multidimensional apathy. It effectively captures the characteristic Executive and Initiation apathy profile in ALS, supporting its clinical and research utility.\n
