The Scales of Independent Behavior-Revised (SIB-R) is a comprehensive, norm-referenced assessment of adaptive and maladaptive behaviour, designed to establish the type and amount of special assistance needed by people with disabilities. It provides a comprehensive assessment of 14 areas of adaptive behaviour and 8 areas of problem behaviour
Three versions are available:
- Full Scale: 283 items
- Short Form: Brief, screening version
- Early Development Form: Brief version for young children or individuals with developmental functioning levels below eight years of age
All items appear in each response booklet to facilitate either administration procedure.
Administered in a structured interview or by way of a checklist procedure, the SIB-R can be used for diagnosis, program planning, determining eligibility, and assessing outcomes.
The SIB-R covers 14 subscales, organised into 4 adaptive behaviour clusters:
- Motor Skills
- Personal Living Skills
- Social Interaction and Communication Skills
- Community Living Skills
Problem behaviour items are grouped into eight types:
- Hurtful to Self
- Unusual or Repetitive Habits
- Hurtful to Others
- Socially Offensive Behavior
- Destructive to Property
- Withdrawal or Inattentive Behavior
- Disruptive Behavior
- Uncooperative Behavior
The SIB-R includes a Support Score, a weighted measure of maladaptive and adaptive behaviours indicating the support, supervision, and resources an individual needs. It also contains a functional limitations index, used to define the presence and severity of adaptive behaviour limitations.
The Individual Plan Recommendation (IPR) form is used to plan and track a person's support and service needs and goals.
