ABSTRACT

Parent reports, specifically maternal reports, are the most widely used measures of child functioning in the developmental and the clinical literatures. In the first large-scale study of temperament in childhood, Thomas, Chess, Birch, and colleagues (Thomas, Chess, & Birch, 1968; Thomas, Chess, Birch, Hertzig, & Korn, 1963) relied on parental reports. Until recently almost all temperament research with children focused on parental reports.
