The Aberrant Behavior Checklist-Community: factor validity and effect of subject variables for adults in group homes

Abstract

The factor validity of the new Aberrant Behavior Checklist-Community (ABC-C) was determined with 1,040 group home residents. Exploratory factor analysis indicated that the factor structure derived from the original ABC appears to be valid for the ABC-C when used with this population. Coefficients of congruence showed a high level of concordance with the original factor structure, and internal consistency continued to be high for each of the five subscales. Analyses for the effects of age, gender, and level of mental retardation indicated that some correction is appropriate for each of these variables when scoring the ABC-C. Further analyses explored the effects of subjects variables such as visual and auditory handicaps and the presence of epilepsy or Down syndrome. Psychotropic medication use was often associated with subscale score differences. The original ABC factor structure appears valid for scoring the ABC-C with community-based adults, at least those living in group homes.
