A contemporary view of early childhood motor development considers environmental influences as critical factors in optimal growth and behavior, with the home being the primary agent. However, minimal research exists examining the relationship between motor development and the home. The present dissertation addresses this gap with the goal of creating an innovative parental self-report instrument for assessing the quality and quantity of factors (affordances and events) in the home that are conducive to enhancing motor development in children ages 18-to-42 months. In Study 1, following initial face validity determination, expert opinion feedback and selective pilot-testing, construct validity was examined using 381 Portuguese families. Factor analysis techniques were used to (1) compare competing factorial models according to previous theoretical assumptions, and to (2) analyze the fit of the preferred model. Of the five plausible models tested, the 5-factor solution provided the best fit to the data. Reliability was established through the scale reliability coefficient with a value of .85. Study 2 tests for the content validity of the instrument, examining the relationship between the inventory and level of motor development. Fifty-one (51) participants from the original sample were assessed for motor development using the Peabody Developmental Motor Scales II (PDMS2). Comparisons were made between the PDMS2 classifications of the AHEMD-SR quartile groups. Results supported the primary hypothesis, that is, less favorable motor development was associated with less availability of home affordances. Furthermore, the interaction of (factors) Inside Space and Variety of Stimulation was significantly related to both Gross and Total Motor Development scores. The findings of these two studies suggest that the AHEMD-SR is a valid and reliable instrument for assessing how well home environments afford movement and potentially promote motor development.
