title: Reliability and validity of the McDonald Play Inventory.
abstract: OBJECTIVE
  This study examined the ability of a two-part self-report instrument, the McDonald Play Inventory, to reliably and validly measure the play activities and play styles of 7- to 11-yr-old children and to discriminate between the play of neurotypical children and children with known learning and developmental disabilities.
  
  
  METHODS
  A total of 124 children ages 7-11 recruited from a sample of convenience and a subsample of 17 parents participated in this study.
  
  
  RESULTS
  Reliability estimates yielded moderate correlations for internal consistency, total test intercorrelations, and test-retest reliability. Validity estimates were established for content and construct validity.
  
  
  CONCLUSIONS
  The results suggest that a self-report instrument yields reliable and valid measures of a child's perceived play performance and discriminates between the play of children with and without disabilities.
