  • Title: The scaling of the Katz Adjustment Scale in a traumatic brain injury rehabilitation sample.
    Author: Goran DA, Fabiano RJ.
    Journal: Brain Inj; 1993; 7(3):219-29. PubMed ID: 8508178.
    Abstract:
    Based on the KAS-R1 ratings completed by 88 relatives of clients who had enrolled in a post-acute rehabilitation programme, the 10 component groups discerned by Fabiano and Goran [1] were submitted to a classical analysis of tests. Seventy-nine items were found to contribute to the internal consistency of their respective component groups, resulting in alpha values ranging from 0.75 to 0.93 for the component groups. Intercorrelations between components suggested that while some degree of overlap existed between groups, they represented discrete categories of neurobehavioural functioning. Second-order components, as determined by principal-component analysis, discern two significant component groups. These two components correlated moderately, yielding a value of 0.49. The findings indicate that the revised KAS-R1 exhibits considerable potential for clinical utility. Further research is needed to investigate the validity of this instrument in accurately depicting behavioural manifestations of those who have incurred traumatic brain injury.
