Abstract

Archival data for subjects used in this study were collected over the past 18 years through the Adult Acquired Brain Injury Program (ABIP) at Chedoke Hospital in Hamilton, Ontario. Of the 966 subjects in the initial sample who were referred for a routine neuropsychological evaluation following a craniocerebral trauma (CCT), 331 met the employed inclusionary criteria: (1) single incident of CCT; (2) no history of additional neurological diseases; (3) WAIS-R FSIQ greater than 85 and/or estimated reading skills above grade 5 level; and (4) valid MMPI profiles (i.e., F < 89, L < 65, and K < 65). Emotional and psychosocial functioning in individuals with CCT was investigated by subjecting the Minnesota Multiphasic Personality Inventory (MMPI) profiles of individuals in randomly split samples (n = 166; n = 165) to a three-step cluster analytic approach. A seven cluster solution was adequately replicated across samples and across clustering techniques: (1) the profile for subtype 1 was indicative of marked somatic, internalizing, and externalizing behavioural difficulties (Combined Somatic-Internalized-Externalized); (2) the profile for subtype 2 was indicative of no concerns or normal functioning (Normal); (3) the profile for subtype 3 was indicative of marked internalizing difficulties (Internalized); (4) the profile for subtype 4 was indicative of primarily mild somatic and pain concerns (Somatic); (5) the profile for subtype 5 was indicative of mild disinhibition and externalizing behavioural difficulties (Mild Externalized); (6) the profile for subtype 6 was indicative of severe emotional, psychosocial, and behavioural disturbances (Severe Psychopathology); and (7) the profile for subtype 7 was indicative of mild internalizing difficulties (Mild Internalized). The relation between subgroup membership and various demographic variables (i.e., nature of accident, sex, marital status, pre-injury vocation, time post-injury, age at testing, estimated levels of cognitive functioning, highest level of education) and loci of brain damage was also investigated.Dept. of Psychology.
