Contributions of school classification,sex, and ethnic status to adaptive behavior assessment

This study investigated the contributions of school classification (regular, EMR) and sex and ethnic status to domain scores from the Public School Version of the AAMD Adaptive Behavior Scale. For this investigation data were available from a sample of more than 1,600 regular and EMR subjects approximately equally distributed between the sexes among white, black, and Spanish-background subjects from ages 7 to 13. The results replicated earlier findings that domain scores were valid for differentiating among children of different adaptive behavior levels as inferred from school classification status. Ethnic status was not a unique contributor to Part One domain scores when the effects of classification were accounted for. On the Part Two domains, ethnic status was a significant contributor to some domain scores, but not at all age levels. Similarly, sex made few unique contributions to domain scores on Part One of the Scale, but it was a significant factor on some domains of Part Two at some age levels.the author concluded that the Scale was valid for differentiating among pupils assigned to regular and EMR classes from ages 7 to 12. The failure of sex and ethnic status to make contributions to Part One domain scores suggests that there are common expectancies for personal independence and responsibility between boys and girls from different ethnic groups.From the analysis of the contributions of sex and ethnic status to the Part Two domains, the author inferred that difference in environmental tolerance for affective or emotional responses to the school or community environment was a more reasonable explanation than the inference that girls and boys or children grom different cultural backgrounds were inherently different with respect to these behaviors. The Public School Version of the AAMD Adaptive Behavior Scale is valid for assessing adaptive behavior of children in public school and relatively independent of effects attributable to sex or ethnic status.
