“…Illustratively, low levels of agreement between teacher and parent ratings are found even when steps are taken to minimize such potential measurement artifacts by ensuring that rating instruments: (a) possess acceptable levels of internal scale consistency and interobserver reliability for observations obtained (Achenbach et al, 1987); (b) assess parallel dimensions of child behavior in the home and the school (e.g., Hinshaw, Morrison, Carte, & Cornsweet, 1987); and (c) exhibit adequate criterion validity for both parent and teacher ratings of child adaptation (Kendall, Cantwell, & Kazdin, 1989; McConaughy, Achenbach, & Gent, 1988). Overall, these findings suggest that divergence between teacher and parent ratings of child adaptation may reflect actual differences in behavior at school and at home (Achenbach et al, 1987; Glow, 1980; McGuire & Richman, 1986; Sandberg, Rutter, &Taylor, 1978). If so, there remain the questions of why such differential adaptation may be present and what the implications are of such divergence for understanding and assessing both current functioning and pathways to disorder.…”
