Relationships among Wechsler intelligence and memory scale quotients in adult closed head injured patients.

Correlations and discrepancy scores (Full Scale IQ minus Memory Quotient) among Wechsler intelligence and memory quotients were assessed in a sample of 126 closed head injured (CHI) adults. Results indicated a slight, generalized decrease in CHI patients' mean level of performance. A significant correlation of .76 was obtained between patients' IQ and MQ scores. Discrepancy scores were relatively smaller than those found in prior research and were influenced partially by the patient's age and by time of testing postinjury. The relative magnitude of discrepancy scores found in CHI is discussed in relationship to other groups of brain-injured patients.
