The Scales of Independent Behavior-Revised (SIB-R) is a comprehensive, norm-referenced assessment of adaptive and maladaptive behavior. It may be administered in a structured interview or by a checklist procedure. All items appear in each response booklet to facilitate either administration procedure.

The SIB-R is a revision of the Scales of Independent Behavior, published in 1984, and includes a number of improvements and additions.

OrganizationThe SIB-R has three different forms: the Full Scales, the Short Form, the Early Development Form. Each of these forms includes the Problem Behavior Scales, which covers eight problem behavior areas organized into three broad maladaptive behavior indexes (Internalized, Asocial and Externalized) and a total maladaptive score (General Maladaptive Index). The SIB-R allows examiners to rate the frequency and severity of problem behaviors and asks open-ended questions to get more specific information regarding a person’s problem behaviors and the typical consequences.

Administration The SIB-R can be administered using either a structured interview or checklist procedures. The checklist-administration procedure is often preferred when a face-to-face interview is not necessary or practical. These options give examiners maximum flexibility when using the SIB-R.

Technical The SIB-r was nationally normed on over 2,180 individuals; the sample reflects the 1990 US Census characteristics. Extensive evidence of the reliability and validity of the SIB-R is documented in the manual. The studies reported show the SIB-R is a strong developmental measure of adaptive behavior as well as a reliable measure of problem behavior. The test is strongly related to other adaptive behavior measures and is highly predictive of placements in different service settings and arrangements.

• 
  Statistically linked to the WJ-R for normative comparisons of intellectual ability and functional independence.


• 
  Statistically linked to the Checklist of Adaptive Living Skills and the Adaptive Living Skills Curriculum for ease in programming and intervention.

InterpretationA wide array of scores are available to examiners using the SIR-R. In addition to the developmental and peer comparison scores, examiners can obtain an RMI for each subscale and cluster in the test.

The SIB-R contains a functional limitation index, which can be used to define the presence and severity of adaptive behavior limitations. This measure is similar to the functioning levels in the SIB but has been improved in the SIB-R by using more descriptive language to predict functional levels and limitations.

The Support Score is a weighted measure of maladaptive and adaptive behaviors that is used to determine the support, supervision, and resources and individual needs. It is categorized into six broad levels of support: Pervasive, Extensive, Frequent, Limited, Intermittent, and Infrequent or No Support. Higher scores reflect increased functional independence and a decreased need for support, while lower scores indicates a need for more support.
