Abstract

The efficacy of cognitive remediation strategies for victims of traumatic brain injury (TBI) has sparked much controversy over the years. In the field of applied research, single-participant research designs are the best ways to answer the question of treatment efficacy. Previous case studies and single-participant, multiple baseline designs have suffered from various methodological flaws, which make their results suspect. In the current single-participant, multiple baseline investigation, three individuals received treatment for recall of narrative information, while two other condition were held at a baseline. Immediate, delayed, and long-term memory in both free recall and multiple choice recall tasks were evaluated over a period of approximately five months. The results of this study indicate improvement in all of the aforementioned areas. Due to the heterogeneity of the TBI population, each participant showed varying degrees of improvement, which coincided with the degrees of their injuries. The results of this study may prove to be very valuable for those individuals returning to the academic setting, as differentiation between free recall and multiple choice recall may be easily applied to the classroom and testing environments.
