The ICAP, in addition to measuring adaptive and maladaptive behavior, also gathers a compact but comprehensive set of information about an individual’s demographic characteristics, diagnoses, support services needed and received, and social/leisure activities. Scoring and database software prints reports and maintains current and historical information on up to 10,000 clients as well.
The ICAP’s adaptive and maladaptive behavior sections contain items selected from the Scales of Independent Behavior (SIB-R) with norms for infants through adults. The SIB-R, revised in 1996, is distinguished by several features. It contains an excellent behavior problem scale in addition to its adaptive behavior assessment, and provides a unique score which reflects overall independence based on adaptive and maladaptive behavior combined. It has norms that extend beyond adolescence — from 3 months to over 80 years. It can be administered either as a questionnaire or as a carefully structured interview, with special materials to aid the interview process. It has a short form, a short form for children, and a short form adapted for individuals who are blind.
Like the SIB-R, the ICAP also yields a Service Score, a combined measure of adaptive and maladaptive behavior indicative of overall need for care, supervision, or training. Because the ICAP is shorter than the SIB-R, its reliability is slightly less, but still excellent when compared to other scales.
