Although research suggests the experience of pain is closely related to PTS among trauma-exposed groups, there has been little exploration of the processes that may link pain intensity to greater PTS among trauma-exposed Latinos. The current study explored insomnia, a common problem associated with both pain intensity and PTS, as a mechanism in the association between pain intensity and PTS among trauma-exposed Latinos (N = 208, Mage = 39.39 years, SD = 11.48) attending a Federally Qualified Health Center. Results indicated that insomnia partially explained the relationship between pain intensity and PTS total score (B = 0.25, 95% CI [0.12, 0.43]), as well as re-experiencing (B = 0.09, 95% CI [0.04, 0.17]), avoidance (B = 0.09, 95% CI [0.04, 0.17]), and arousal symptoms (B = 0.10, 95% CI [0.04, 0.17]). Future work is needed to explore the extent to which insomnia accounts for relations between pain and PTS using longitudinal designs to further clarify theoretical health disparity models involving these comorbid conditions.
