Gender as Potential Moderator of Associations Among Trauma Exposure, Posttraumatic Stress Disorder Symptoms, and Alcohol Use Disorder Symptoms in Young Adults

Traumatic events (TEs), posttraumatic stress disorder (PTSD) symptoms, and alcohol use disorder (AUD) symptoms can significantly impair functioning, yet little is known about whether associations among these variables differ between men and women within young adult samples. The current study conducted a path analysis of archival, longitudinal data from the Drug Use Trajectories: Ethnic/Racial Comparisons 1998-2002 (DUT) study (Turner, 2011) to examine gender differences as a possible moderator of the relations between TEs, PTSD symptoms, and AUD symptoms among 1,076 young adults (aged 18-23 years) residing in South Florida. The sample included 580 male (53.9%) and 496 female (46.1%) participants, whose ethnicity was self-reported as African American (n = 280, 26.0%), non-Hispanic White (n = 268, 24.9%), other Hispanic (n = 267, 24.8%), and Cuban (n = 261, 24.3%). Significant positive associations were found between TEs and PTSD symptoms, beta s = .08-.30; PTSD and AUD symptoms, beta s = .09 - .10; PTSD symptoms over time, beta = .52; and AUD symptoms over time, beta = .46. In addition, for male but not female participants, a higher frequency of PTSD symptoms at Wave I was related to more AUD symptoms at Wave II, beta = .09. Findings build upon existing research to further elucidate the role of gender as a potential moderator of the associations among TEs, PTSD symptoms, and AUD symptoms for young adults and provide important implications for future research and clinical practice, including informing mental health prevention and treatment efforts.
