Objective: To use confirmatory factor analysis to test the construct validity of the proposed "DSM-5" symptom model of autism spectrum disorder (ASD), in comparison to alternative models, including that described in "DSM-IV-TR." Method: Participants were 708 verbal children and young persons (mean age, 9.5 years) with mild to severe autistic…

Confirmatory factor analysis was used to evaluate the factor structure of the eight cross-informant scales of the Child Behavior Checklist (T. M. Aschenbach, 1991) using data from 631 youth ages 8 to 18. Results support Aschenbach's eight- correlated-factor model and the construct validity of the measure's scores. (SLD)

The contributions of specific scales of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) to the classification of 180 adolescent substance abusers into groups characterized by aspects of behavioral control were studied. Seven scales made significant contributions to the classification of substance abusers into three groups, with…

Responses of 123 adults were used to develop a measure to assess expectations and stereotypes about adolescents. The developed scale was refined and tested with 361 college students and 112 parents of young adolescents. The measure's subscales demonstrate adequate internal consistency, test-retest reliability, and construct validity. (SLD)

The perceptions of students toward conservation and nature utilization and their behavior toward the environment were studied with 725 Danish adolescents and a previously studied group of Bavarian adolescents. Following construct validation, comparison of mean within-region factor values reveals substantial differences between countries. (SLD)

Relative fits of 3 factor-structure models of adolescent reckless behavior were examined using the 10-item Reckless Behavior Questionnaire with 1,357 college and 181 high school students. Both one- and two-factor models were found to be satisfactory representations. Implications of a study of construct validity are discussed. (SLD)
