Dimensions of childhood trauma and their direct and indirect links to PTSD, impaired control over drinking, and alcohol-related-problems.

Introduction: Post-Traumatic Stress Disorder (PTSD) develops after experiencing events that evoke fear, helplessness, or horror. The Hyperarousablity Hypothesis suggests that those with PTSD may drink more to dampen physiological reactivity. We examined the direct and indirect relationships between childhood trauma (e.g., physical-neglect, emotional-abuse, physical-abuse, sexual-abuse) versus an emotionally-supportive-family on PTSD, impaired control over drinking (IC), alcohol-use, and alcohol-related-problems. IC reflects consuming more alcohol than one originally intended.
Methods: We fit a multiple-group SEM to data on 835 participants. Mediational analyses were conducted by using the (K = 20,000) bootstrap technique with confidence intervals.
Results: Physical-neglect was directly linked to more IC among both genders. Emotional abuse was also found to be directly linked to more PTSD among both genders. Furthermore, PTSD was directly linked to more impaired control over alcohol use (IC) among both genders. Mediational analyses showed that physical-neglect was indirectly linked to more alcohol-related-problems through increased IC. Having an emotionally supportive family was directly linked to fewer PTSD symptoms among women. For both genders, emotional abuse was indirectly linked to more alcohol-related-problems through more PTSD symptoms, impaired control over alcohol use difficulties, and in turn, more alcohol-use. Sexual abuse was indirectly linked to increased alcohol-related- problems through increased PTSD symptoms and more IC, and in turn, more alcohol-use among men.
Conclusions: Recalled childhood trauma (sexual and emotional abuse) may contribute to PTSD symptoms and dysregulated drinking. In conclusion, our data suggest that reducing PTSD symptoms may assist individuals in regaining control over their drinking.
