The MUSAD prompts diagnostically relevant behaviors in twelve musical interactional situations. This study explores the psychometric properties of a short version (MUSAD-Short) for ASD screening. Method Excerpts from 60 videotaped assessments conducted with the original MUSAD were re-coded with a reduced item set. Based on these ratings, items were selected for the MUSAD-Short. Criterion validity of the MUSAD-Short was tested by comparing the MUSAD-Short assignment with the clinical ASD diagnosis. Inter-rater reliability was tested on a subsample of 22 individuals. A dichotomous response format was also examined to investigate whether further simplification is possible. Results Four situations (congas; ocean drum; symbolic instruments; movement to music) and fourteen items were selected for the MUSAD-Short. The diagnostic accuracy was appropriate, as indicated by sensitivity/specificity values of 73/75% (AUC =0.78). The inter-rater reliability was excellent, measured by the intra-class correlation (ICC) of.77. After item-dichotomization, sensitivity/specificity values were 73/70% (AUC =0.79). Conclusions The results indicate that the MUSAD-Short provides adequate diagnostic accuracy and sufficient inter-rater reliability. Shortening the original MUSAD is a promising approach to improving the scale?s applicability. However, future studies are needed that assess the MUSAD-Short's clinical and psychometric utility in an independent sample. Also, testing its practicability in children and adolescents with ID is indicated.
