Adjustment Scales for Children and Adolescents and Native American Indians: Factorial Validity Generalization for Ojibwe Youths

Replication of the core syndrome factor structure of the Adjustment Scales for Children and Adolescents (ASCA; P.A. McDermott, N.C. Marston, & D.H. Stott, 1993) is reported for a sample of 183 Native American Indian (Ojibwe) children and adolescents from North Central Minnesota. The six ASCA core syndromes produced an identical two-factor solution as the standardization data through principal axis analysis using multiple criteria for the number of factors to extract and retain. Varimax, direct oblimin, and promax rotations produced identical results and nearly identical factor-structure coefficients. Coefficients of congruence resulted in an excellent match to the factorial results of the ASCA standardization sample and a large, independent sample. It was concluded that for these Ojibwe students, the ASCA measures two independent dimensions of psychopathology (i.e., Overactivity and Underactivity) that are similar to the conduct problems/externalizing and withdrawal/internalizing dimensions commonly found in the child psychopathology assessment literature. © 2006 Wiley Periodicals, Inc.
