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:

1. Full Scale: 283 items
2. Short Form: Brief, screening version
3. 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.
