Construct validity of the Adjustment Scales for Children and Adolescents and the preschool and kindergarten behavior scales: Convergent and divergent evidence

Construct validity (convergent and divergent) of the Adjustment Scales for Children and Adolescents (ASCA; McDermott, Marston, & Stott, 1993) and the Preschool and Kindergarten Behavior Scales (PKBS; Merrell, 1994a) is presented.(-) Regular classroom teachers (n = 38) randomly selected 5- and 6-year-old children (N = 123) and rated them on the ASCA and PKBS in counterbalanced order. Convergent evidence of construct validity was observed for the PKBS Externalizing Problems scale and the ASCA Overactivity syndrome. Divergent evidence of construct validity was provided for the PKBS Externalizing Problems scale and ASCA Underactivity syndrome. Convergent and divergent evidence of construct validity for the PKBS Internalizing Problems scale and ASCA Overactivity, and Underactivity syndromes was mixed. Results were identical to those of Canivez and Bordenkircher (2002). (C) 2002 Wiley Periodicals, Inc.
