Response to goal management training in veterans with blast-related mild traumatic brain injury

Veterans with blast-related mild traumatic brain injury (TBI) experience cognitive deficits that interfere with functional activities. Goal Management Training (GMT), which is a metacognitive intervention, offers an executive function rehabilitation approach that draws upon theories concerning goal processing and sustained attention. GMT has received empirical support in studies of patients with TBI but has not been tested in Veterans with blast-related mild TBI. GMT was modified from 7 weekly to 10 biweekly sessions. Participants included six combat Veterans that reported multiple blast exposures resulting in symptoms consistent with mild TBI. Group analysis showed a significant improvement in measures of executive function derived from performance on the computerized Tower of London. There were no significant changes on self/informant questionnaires of executive function, indicating a lack of generalization of improvement from the clinic to everyday activities. Overall, while the data indicate efficacy of GMT in the rehabilitation of combat Veterans with executive function deficits because of blast-related mild TBI, enhancement of generalization is needed.
