MMPI correlates of verbal-intellectual deficits in patients with left hemisphere lesions.
This study investigated the emotional adjustment of patients (N = 31) with left hemisphere damage (LHD) as a function of the degree of impairment in verbal intelligence as measured by the Wechsler Adult Intelligence Scale. A multivariate comparison was made of the composite MMPI profiles of three groups of LHD patients classified according to Verbal IQ. The three groups produced fairly similar composite profiles, which indicated the presence of mild dysphoria, dissatisfaction, withdrawal, decreased initiative, and mild somatic preoccupations. Significant correlations emerged between the degree of verbal-intellectual disability and MMPI F, PT, SC, and SI. However, when the variance in MMPI scores due to premorbid status (education) was partialled out, these correlations dropped to nonsignificant levels. These findings failed to support previous studies that linked verbal deficits with emotional disturbance, and they underscore the importance of premorbid intelligence in the psychological adjustment to organic impairment.
