Figure 2. PTSD symptom severity is associated with sensory sensitivity in Veterans with TBI.

Figure 2

(A) PTSD symptom severity determined by PCL-5 score (0–80, higher = worse PTSD) stratified by self-reported sensory sensitivity in Veterans with TBI: no sensory sensitivity (open bars, n = 36), only light sensitivity (light gray bars, n = 12), only noise sensitivity (dark gray bars, n = 24), and both light and noise sensitivity (filled bars, n = 23). Significantly worse scores on PCL-5 were seen in subjects reporting greater sensory sensitivity to light and noise. One-way ANOVA for PCL-5 (P < .001); * = P < .05 versus Neither; † = P < .05 versus Light; ‡ = P < .05 versus Noise. (B) The correlation between individual light and noise sensitivity scores and corresponding PCL-5 scores. Thus, there are n = 95 data points for both light sensitivity versus PCL-5, and noise sensitivity versus PCL-5. Data points are nudged slightly for illustrative purposes to prevent overlap between duplicate light and noise sensitivity scores. ANOVA = analysis of variance, PCL-5 = PTSD checklist for DSM-5, PTSD = posttraumatic stress disorder, TBI = traumatic brain injury.
