Abstract

This paper discusses positive therapeutic gains made with veterans whose primary treatment for PTSD was artifact corrected neurofeedback. Assessments completed after both 20 and 40 half-hour sessions of treatment identified significant improvements for both auditory and visual attention using the IVA-2 CPT and the veterans reported significant improvements in their well-being based on the General Well-Being Scale (GWBS). It was discovered that neurofeedback impacted individuals’ overall auditory attention and that the IVA-2 global auditory test scores significantly improved after both 20 (p < .007, Cohen’s d = 0.5) and 40 training sessions (p < .0001, Cohen’s d = 0.8).  Veterans were found to have significant enhancements specifically in auditory vigilance (p < .03), processing speed (p < .0009) and focus (p < .01). The IVA-2 global measure of visual attention was also found to show significant improvements after 20 sessions (p < .004, Cohen’s d = 0.5) and after 40 sessions (p < .06, Cohen’s d = 0.4). Specific improvements in visual processing speed (p < .04) and focus (p< .02) were identified after 40 sessions. Ratings of well-being also significantly improved after treatment (p < .001, Cohen’s d = 0.8) with 84% of the veterans improving five points or more on the GWBS. These improvements in well-being were found to be significantly correlated with increases in veterans’ overall auditory attention (r = .44, p < .03) and auditory processing speed (r = .57, p < .005).
