Preliminary Validation of the Motor Skills Rating Scale

This study examined psychometric properties of the Motor Skills Rating Scale (MSRS), a questionnaire designed for classroom teachers of children in early elementary school. Items were developed with the guidance of two occupational therapists, and factor structure was examined with an exploratory factor analysis (EFA). The resulting model showed good fit with 19 items that loaded on 3 subscales: Shapes and Letters, Classroom Fine Motor, and Body Awareness.

Children with higher ratings on the Classroom Fine Motor scale of the MSRS also had higher teacher-rated and directly assessed mathematics achievement. Study findings provided preliminary support for the utility and validity of a brief teacher report of elementary children’s motor ...
