Abstract: Compensatory Cognitive Training (CCT) is a group-based cognitive rehabilitation intervention that has been shown to improve cognition following mild traumatic brain injury (mTBI). However, statistically significant changes do not always reflect clinically meaningful differences. We reanalyzed data from Storzbach et al. using clinically relevant cut scores to determine whether CCT resulted in clinically meaningful improvements. Veterans with mTBI were randomized to CCT or treatment as usual (TAU). Data were used from 72 participants with baseline and 10-week assessments of subjective and objective neuropsychological functioning, satisfaction with life, depressive symptoms, and posttraumatic stress disorder symptoms. Using established cut scores when available, or a .8 SD difference between baseline and 10-week follow-up scores, we categorized outcomes as clinically improved or unimproved. CCT was associated with 5.61 (95% CI: 1.39, 22.60) greater odds of clinically significant improvement on delayed verbal recall (i.e., 18% of participants) and 4.71 (95% CI: 1.62, 13.75) greater odds of clinically significant improvement in subjective memory relative to TAU (i.e., 32% of the participants), but no other clinically significant improvements were detected. Although few participants experienced cognitive impairment at baseline, for some, cognitive rehabilitation resulted in clinically meaningful improvements in objective and self-reported memory.
