UNASSIGNED: The MUSAD was developed as a diagnostic observational instrument in an interactional music framework. It is based on the ICD-10/ @entity4987 criteria for @entity72 ( @entity72 ) and was designed to assess adults on a lower level of functioning, including individuals with severe @entity73 . This study aimed to evaluate the psychometric properties of the newly developed instrument. METHODS: Calculations were based on a consecutive clinical sample of N=76 adults with @entity717 ( @entity717 ) suspected of @entity72 . Objectivity, test-retest reliability, and construct validity were calculated and a confirmatory factor analysis was applied to verify a reduced and optimized test version. RESULTS: The structural model showed a good fit, while internal consistency of the subscales was excellent (  >.92). Item difficulties ranged between .04 <=pi <=.82 and item-total correlation from .21 to .85. Objectivity was assessed by comparing the scorings of two external raters based on a subsample of n=12; interrater agreement was .71 (ICC 2, 1). Reliability was calculated for four test repetitions: the average ICC (3, 1) was .69. Convergent @entity72 measures correlated significantly with the MUSAD, while the discriminant Modified Overt Aggression Scale (MOAS) showed no significant overlap. CONCLUSION: Confirmation of factorial structure and acceptable psychometric properties suggest that the MUSAD is a promising new instrument for diagnosing @entity72 in adults with @entity717 .
