scales of cognitive ability for traumatic brain injury (scatbi)

Scales of Cognitive Ability for Traumatic Brain Injury (SCATBI) assesses cognitive and linguistic functions and severity of injury of brain-injured adults and adolescents, showing progress during recovery. It is time-efficient assessment

Assesses cognitive and linguistic abilities of adolescents and adults with head injuries.

  • Age Range: Adolescent and adult
  • Time: 30-120 minutes

The SCATBI assesses cognitive and linguistic functions of brain-injured patients, establishes the severity of the injury, and shows progress during recovery. It is a time-efficient assessment, permitting selective administration of only the scales most useful for an individual patient.

Unlike other tests for this population, the SCATBI progresses in difficulty levels. This permits patients who functioned at very high levels, prior to injury, to continue to be assessed with the SCATBI, as they regain use of higher-level abilities (such as complex organization and abstract reasoning).

The SCATBI consists of five subtests:

  1. Perception/Discrimination
  2. Orientation
  3. Organization
  4. Recall
  5. Reasoning

Because the subtests use the same standard score scale, direct comparison of performance on the different subtests is possible.

The SCATBI was standardized on a sample of head-injured patients and a sample of matched adults with no history of head injury. Internal consistency coefficients were high (.90 or higher) for all subtests. Test-retest coefficients from a patient sample ranged from a low of .73 (Reasoning) to a high of .89 (Recall).

Concurrent validity was supported by correlations between SCATBI scores and levels on the Rancho Los Amigos Scales. Discriminant analysis showed that the five SCATBI scales accurately classified 94 per cent of the head-injured participants and 79 per cent of the non-injured participants.

The SCATBI Kit includes an Examiner’s Manual, a Stimulus Manual, 25 Record Forms, a Stimulus Audiocassette and a Stimulus Card Set.
