Abstract:
The Postconcussion Syndrome Questionnaire (PCSQ) total and factor scores were compared to the primary validity and clinical scales from the Minnesota Multiphasic Personality Inventory-II (MMPI-2) in an effort to better define the structure of the PCSQ. The sample used was composed of a heterogeneous group of 79 patients referred for clinical neuropsychological evaluation. In reviewing the results, patients with higher PCSQ scores presented with higher clinical elevations on the MMPI-2. In addition, each of the PCSQ factor scores was related to a different pattern of MMPI-2 scales and subscales. The somatic factor was most associated with physical ailments, generalized distress, and social insecurity. In contrast, the psychological factor was related to complaints of dysphoria, brooding, and social connectedness. The cognitive and infrequent factors were related to reports of cognitive changes and unusual sensory experiences, respectively. The data present validation of the multifaceted nature of the PCSQ and its general sensitivity to subjective complaints.
