Examining the Relationship Between PTSD Symptom Clusters and Drinking to Cope Motives on Drinking Outcomes

Examining the Relationship Between PTSD Symptom Clusters and Drinking to Cope Motives on Drinking Outcomes Fatima Tariq, Dept. of Psychology, with Dr. Christina Sheerin, Dept. of Psychology and Virginia Institute for Psychiatric and Behavioral Genetics Posttraumatic stress disorder (PTSD) is prevalent among combat veterans, and its symptoms are categorized (in DSM-IV) in clusters of: reexperiencing, avoidance, and hyperarousal. Alcohol use disorder (AUD), often preceded by risky drinking behaviors such as binge drinking, and PTSD comorbidity is especially common in veteran populations. One theory underlying this comorbidity is that individuals use alcohol to self-medicatePTSD symptoms. Extant literature more often examines the relation on PTSD symptom severity as a unitary construct rather than on individual symptom clusters,a gap the present study attempts to fill.The aims of this study were to examine whether PTSD total symptom severity and each symptom cluster had significant main effects on a range of alcohol use outcomes (total frequency, binge drinking, and risky drinking) and determine whether self-reported drinking to cope motives moderate the relationship between PTSD symptoms and alcohol use outcomes. It was hypothesized that a) the hyperarousal symptom cluster would most strongly predict alcohol outcomes, as compared to other clusters, and b) drinking to cope would moderate the relationship between PTSD symptoms on alcohol use outcomes, such that those who reported greater drinking to cope motives would endorse higher severity of alcohol use. The present sample (N = 211) consists of a combat trauma-exposed subsample of individuals from a larger study of OIF/OEF veterans (90.5% male, 70.1% white, 70.1%) assessed for PTSD, determined through clinical interview with the Clinician-Administered PTSD Scale for DSM-IV. Participants also completed the drinking to cope subscale from the Drinking Motives Questionnaire (DMQ-Cope) and the Timeline Folllowback measure (TLFB; with outcome measures including total number of drinks per month, risky drinking status, and total number of binge days). Analyses consisted of a series of separate hierarchical regression models, with PTSD severity scores (total and symptom cluster) entered in Step 1, DMQ-Cope entered in Step 2, and their interaction entered in Step 3. Linear regressions were conducted for the continuous number of drinks per month, a logistic regression was conducted for risky drinker status, and a negative binomial regression was conducted for number of binge drinking days. In the linear regressions examining whether total PTSD symptom severity and each symptom clusters had significant main effects on total number of drinks per month, while all PTSD severity scores were initially associated in Step 1 with total alcohol use (all ps \u3c0.02), when DMQ-Cope was added to the model (Step 2), they were no longer significant. In the final step (Step 3), DMQ-Cope showed main effects (all ps \u3c 0.001), but there were no significant interaction effects found (all ps \u3e 0.15). The pattern for both risky drinking status and number of binge drinking days was the same. PTSD total and cluster scores were not associated with either outcome in any of the Steps (all ps \u3e 0.35), DMQ-Cope showed a main effect in all models (all ps \u3c 0.003), and no interaction effects were found (all ps \u3e 0.107). The current findings show that across all alcohol use outcomes, drinking to cope is a strong predictor of alcohol use outcomes, over and above the impact of PTSD symptoms in this sample. Drinking to cope has been independently associated with both PTSD and alcohol misuse and the current study’s findings add to the existing literature. Contrary to hypotheses, however, hyperarousal symptoms were not associated with alcohol use outcomes and no moderations were found. Limitations include limited diversity within the sample and future research would benefit from examination in civilian populations, extension to different types of traumas, and examination of other alcohol use outcomes, such as risky drinking behaviors and problems.https://scholarscompass.vcu.edu/uresposters/1351/thumbnail.jp

Presence of Mind: A Political Posture

The political posture often encouraged in liberatory movements is that of urgency. Urgency is based on the idea that if oppressed peoples do not act “now,” then their fate is forever sealed as subordinates within social and political power hierarchies. This paper focuses on a contrasting political posture, termed presence of mind, motivated by the current political atmosphere of distrust and disenfranchisement in which some Muslim-Americans find themselves. Presence of mind is defined as the ability to critically unpack visceral affective responses to injustice—giving special consideration to power structures, one’s social location, and relationships—and then to asses an appropriate response in virtue of that consideration that best upholds our commitments. This paper argues that cultivating presence of mind acknowledges the complexities of the Muslim-Americans’ identity while providing a posture that allows the resistor to best represent their political commitments

Can Doctors Maintain Good Character? An Examination of Physician Lives

Can doctors maintain good character? This paper shifts the focus from patient care to ethical considerations that bear on the physician and impact her as a person. By decentering patient care, the paper highlights certain factors that habituate a particular way of reasoning that is not conducive to inculcating good character. Such factors include, standards of professionalism, being influenced by external monitors, and emphasis on adherence to guidelines. While such factors may benefit patients, they often adversely affect the character of physicians

Individual Expression Versus the Submissive Woman in France

While still in the midst of their study abroad experiences, students at Linfield College write reflective essays. Their essays address issues of cultural similarity and difference, compare lifestyles, mores, norms, and habits between their host countries and home, and examine changes in perceptions about their host countries and the United States. In this essay, Fatima Falcon Ontiveros describes her observations during her study abroad program at the Institut Américain Universitaire in Aix-en-Provence, France

Logarithmic potentials on Pn\mathbb{P}^n

We study the projective logarithmic potential $\mathbb{G}_{\mu}$ of a Probability measure $\mu$ on the complex projective space $\mathbb{P}^{n}$. We prove that the Range of the operator $\mu\longrightarrow \mathbb{G}_{\mu}$ is contained in the (local) domain of definition of the complex Monge-Amp\`ere operator acting on the class of quasi-plurisubharmonic functions on $\mathbb{P}^n$ with respect to the Fubini-Study metric. Moreover, when the measure $\mu$ has no atom, we show that the complex Monge-Amp\`ere measure of its Logarithmic potential is an absolutely continuous measure with respect to the Fubini-Study volume form on $\mathbb{P}^{n}$Comment: 7 page
