title: Development of the Affordances in the Home Environment for Motor Development-Infant Scale.
abstract: BACKGROUND
  The present study reports the development and application of the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS), a parental self-report designed to assess the quantity and quality of affordances in the home environment that are conducive to motor development for infants aged 3-18 months.
  
  
  METHODS
  Steps in its development included use of expert feedback, establishment of construct validity, interrater and intrarater reliability, and predictive validity. With all phases of the project, 113 homes were involved.
  
  
  RESULTS
  Intraclass correlation coefficients for interrater and intrarater reliability for the total score were 1 and 0.94, respectively. In addition, results indicate that the test has the characteristic of differentiating a wide range of scores. Regression analysis for the AHEMD-IS and motor development using the Alberta Infant Motor Scale supports preliminary evidence for predictive validity.
  
  
  CONCLUSIONS
  Our findings suggest that the AHEMD-IS has sufficient reliability and validity as an instrument for assessing affordances in the home environment, with clinical and research applications.
