Scales of Independent Behavior – Revised (SIB-R)

The Scales of Independent Behavior – Revised (SIB-R; Bruininks, Woodcock, Weatherman, & Hill, 1996) is a comprehensive, norm-referenced assessment of adaptive and problem behaviors.


Administered individually, the SIB-R assesses functional independence and adaptive functioning across settings: school, home, workplace, and community. The authors note that the SIB-R was designed for individual evaluation, individualized program planning, selection, and placement, and to assess service needs. The SIB-R may be administered using the structured interview or a checklist procedure.

Information obtained during the assessment yields two scale scores, the Adaptive Behavior Full Scale score and the Problem Behavior Scale score. Different rating systems are used for the two scales. The Adaptive Behavior items are rated based on the extent to which the individual performs a task completely and independently (with no help or supervision). The Problem Behavior scale is rated based on the frequency and severity of each behavior. Additionally, a Support Scale score is available. This score, based on the information obtained from the other two scales, indicates an approximate level of support that an individual may need in order to be independent in different areas.
