An Exploratory Factor Analysis of the ICAP Maladaptive Behavior Items

摘要

This paper reports the results of an exploratory factor analysis of Individual Client and Agency Planning (ICAP; Bruininks, R. H., Hill, B. K., Weatherman, R. E, and Woodcock, R. W. (1986). Examiner's Manual. ICAP: Inventory for Client and Agency Planning. DEM Teaching Resources, Allen, Texas.) maladaptive behavior items. Subjects included 300 persons living in a state school. Most were adults and two-thirds had profound mental retardation. A principal-components analysis with varimax rotation was performed. A scree plot identified only 1 factor. The items that loaded most highly on this factor were socially offensive behavior, uncooperative behavior, hurts others, disruptive behavior, and property destruction. This factor accounted for 36.3% of the variance. It was labeled external maladaptive behaviors. Results of a factor analysis constraining the number of factors to 3 factors yielded extrapersonal and intrapersonql maladaptive factors and 1 that could not be clearly labeled. The internal consistency of the ICAP maladaptive items was very high.
