WORD FLUENCY GENERATION SKILLS OF HEAD-INJURED PATIENTS IN AN ACUTE TRAUMA CENTER

Two hundred-eighteen acutely brain-injured trauma patients with confirmed diagnosis of initial closed head injury completed two types of word fluency generation tasks, animal naming and single-letter-based word generation. Numbers of responses and inferred strategy utilizations were examined and compared with established norms for non-brain-injured individuals using frequency counts and X2 analyses. Significant differences were noted in response quantity and quality between closed head-injury patients and normals. A positive relationship was noted between level of cognitive functioning and number of word associates generated. Same initial consonant-vowel syllable (see-seed), semantic association (ship-sail), and same initial consonant-consonant blend (tree-trick) strategies were used by all subjects regardless of severity of injury. Quantitative and qualitative differences were noted as a function of severity of cognitive disruption. © 1990.
