0931 Are Certain Types of Trauma More Likely to Create Nightmares?

Abstract Introduction Although nightmares are common among trauma survivors, the posttrauma nightmare remains enigmatic and under-researched. For example, research has yet to examine if certain types of traumas may be more likely to create nightmares, which is this project’s primary question. Additionally, this project examined prevalence rates, gender differences, and the lifespans of posttrauma nightmares. Methods First-year college students completed an online survey that assessed traumas and posttrauma nightmares. Traumas assessed consisted of non-sexual physical traumas, sexual traumas, directly witnessing harm to another, transportation accidents, and natural disasters. Frequency analyses, chi-square analyses, and analyses of variance were conducted. Results Out of our sample (N = 1089), 73.3% (n = 798) reported experiencing a trauma, 15.5% (n = 168) reported experiencing posttrauma nightmares multiple times per month (MTPM; males = 42, females = 126; p < .001), and 4.4% (n = 48) reported experiencing nightmares multiple times per week (MTPW; males = 12, females = 36; p = .06). Time since trauma significantly predicted the occurrence of nightmares multiple times per month (B = -.03, p < .01) and week (B = -.01, p < .001). Only, non-sexual physical traumas (B = 1.78, p < 0.001) and sexual traumas (B = 1.13, p < 0.001) predicted the occurrence of nightmares MTPM (X2 (5, N = 1089) = 59.69, p
