“…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).…”
