Background: Music as alternate engagement (MAE) can be used effectively to distract children during painful or anxiety-provoking medical procedures. For such interventions to be successful, it would seem important to assess the degree to which a child can attend to musical stimuli.
Objective: The purposes of this study were as follows: (a) To establish construct validity by determining the extent to which the Music Attentiveness Screening Assessment (MASA) measures auditory attention; and (b) to gather evidence regarding MASA test-retest and inter-observer reliability.
