ii iii ACKNOWLEDGMENTS A warm and well-deserved thank you to my thesis advisor, Dr. Parente! This research project would not have achieved any amount of success without the contribution of his knowledge and expertise in the field of cognitive rehabilitation after brain injury. Dr. Parente was a patient and dedicated leader during my two years at Towson University, and the insight he provided during our numerous meetings will continue to inspire me throughout my future endeavors. iv ABSTRACT

... cacy of Memory Rehabilitation Therapy Madison Elliott This meta-analysis evaluated 26 studies of memory retraining and recovery that were published between the years 1985 and 2013. The primary purpose of this meta-analysis was to determine the overall effect size (ES) in these studies. The study assessed the significance of the overall ES and determined which of several covariates in these studies predict the obtained ESs. Results indicated a significant average ES (r = .51) in the treatment intervention conditions. There was also a significant average ES (r = .31) in the control conditions, in which participants did not receive any treatment. The largest treatment ESs occurred in studies of stroke patients, and the smallest ESs occurred in studies of patients with traumatic brain injury (TBI). Results showed that memory rehabilitation was an effective therapeutic intervention. However, the results also indicated that significant memory improvement occurred spontaneously over time.
