Objective: Evidence for the use of integrated treatments targeting co-occurring posttraumatic stress disorder (PTSD) and alcohol use disorders is steadily growing. However, limited work has evaluated the temporal association between posttraumatic stress symptoms (PTSS) and alcohol misuse over the course of integrated treatment, with no studies examining such interventions in primary care (PC). The current study examined temporal changes in PTSS and heavy drinking among individuals who received a brief treatment for co-occurring PTSD and alcohol misuse in PC (Primary Care Treatment Integrating Motivation and Exposure; PC-TIME) compared with those who received PC treatment as usual (PC-TAU).

Method: A total of 63 veterans (33 randomized to PC-TIME and 30 randomized to PC-TAU) presenting to PC with co-occurring PTSD and alcohol misuse were included in this study. PTSS and heavy drinking were examined at each treatment session for those in PC-TIME. Veterans in both conditions provided reports of PTSS and heavy drinking at baseline, 8-weeks (post-treatment), 14-weeks, and 20-week follow-ups.

Results: Session-by-session findings for PC-TIME demonstrated that PTSS at Session 1 predicted a greater decrease in heavy drinking from Session 1 to Session 2. Moreover, heavy drinking at baseline predicted greater decreases in PTSS at 8-weeks for those in PC-TIME, whereas the reverse association was found for those randomized to PC-TAU. Additionally, heavy drinking at 8-weeks predicted decreased PTSS at 14-weeks for those randomized to PC-TAU.

Conclusions: The current study evidenced mixed support for the temporal precedence of PTSS and alcohol misuse. Relations between PTSS and heavy drinking appeared to be linked to treatment targets within PC-TIME and varied between treatment condition (PC-TIME versus PC-TAU). Notably, those with greater than average heavy drinking at the initiation of integrated treatment appeared to have greater reductions in PTSS at post-treatment. Results suggest a mutual maintenance model may best characterize the association between co-occurring PTSS and heavy drinking among treatment-seeking individuals.

The opioid epidemic has exposed a gulf in mental health research, treatment, and policy: Most patients with comorbid trauma-related disorder (TRD) and opioid use disorder (OUD) (TRD + OUD) remain undiagnosed or unsuccessfully treated for the combination of TRD symptoms and opioid use. TRD treatments tend to be psychotherapies that are not accessible or practical for many individuals with TRD + OUD, due to TRD treatment models not systematically incorporating principles of harm reduction (HR). HR practices prioritize flexibility and unequivocally improve outcomes and save lives in the treatment of OUD. Considering the urgent need to improve TRD + OUD treatment and outcomes, we propose that the OUD and TRD fields can be meaningfully reconciled by integrating HR principles with classic phasic treatment for TRD. Adding a "prestabilization" phase of treatment for TRD - largely analogous to the precontemplation Stage of Change - creates opportunities to advance research, clinical practice, and policies and potentially improve patient outcomes.

Objective: Evidence from laboratory studies suggests that progesterone may be effective in reducing stress and craving, and may improve cognitive performance in smokers and individuals with cocaine dependence. The objective of this study was to examine if progesterone would attenuate stress-induced craving, anxiety, affect and physiological measures, as well as improve stress-induced cognitive performance (processing speed and selective attention) in individuals diagnosed with alcohol use disorder (AUD) and post traumatic stress disorder (PTSD).

Methods: This laboratory study included (n = 13) participants who were diagnosed with current AUD and PTSD who were randomly assigned to recive either progesterone (200mg bid) or placebo in identical looking capsules for 3 days. On the fourth day they completed a laboratory session. In the morning of the test session, they received the last dose of medication and completed the rest of the laboratory procedures. The procedures included presentation in random order of personalized trauma and neutral scripts with relaxation in between. Main outcomes included measure of craving, anxiety, affect and cognitive performance.

Results: Consistent with other research, trauma scripts produced significantly greater increases in craving, anxiety and negative affect when compared with neutral scripts. Progesterone significantly reduced stress-induced symptoms of craving, anxiety, fear, anger and sadness but had no effect on positive emotions (joy, relaxation). Progesterone was effective in ameliorating stress-induced decreases in cognitive performance.

Conclusions: The findings from this study demonstrate that progesterone can be effective in reducing stress-induced craving, anxiety and negative affect in a laboratory setting in individuals with comorbid AUD and PTSD. Interestingly, progesterone also improved cognitive performance. These findings require replication in a larger clinical trial and may have implications for treatment among individuals with AUD and PTSD.This study was registered as NCT02187224, at www.clinicaltrials.gov.

Objective: Black/African American (AA) individuals are a group at risk for co-occurring posttraumatic stress disorder (PTSD) symptoms and alcohol use due to unique cultural and system-level barriers. Although associations between trauma exposure, PTSD symptoms, and alcohol use are well established across various populations, Black/AA individuals are underrepresented in this literature, and related findings in this population are inconclusive. Thus, the goal of this study was to examine the associations among trauma exposure, PTSD symptoms, and alcohol use in a sample of treatment-seeking, Black/AA adults. We hypothesized that trauma exposure and alcohol use would be positively associated and that this relationship would be mediated by PTSD symptoms.

Methods: This study conducted secondary analysis of screening data from a PTSD and alcohol use disorder clinical trial. Participants were 96 Black/AA adults (57.3% male; 2.0% Hispanic; M age = 44.73, SD = 11.83) who were seeking treatment for alcohol use and endorsed trauma exposure. Associations between trauma exposure, PTSD symptom severity, and quantity and frequency of alcohol use were tested using bivariate correlations and linear regressions. Hypothesized indirect effects were tested using IBM SPSS Statistics Version 27 PROCESS model 4 with bootstrapping.

Results: Findings illustrated a significant positive association between trauma exposure and PTSD symptoms and between PTSD symptoms and drinks per typical drinking day. PTSD symptoms were not significantly associated with number of drinking days. Tests of indirect effects were significant for trauma exposure on drinks per typical drinking day through PTSD symptoms.

Conclusions: Results from the test of indirect effects suggest that among Black/AA adults with heavy alcohol use and trauma exposure, trauma exposure is associated with PTSD symptoms, which in turn is associated with quantity of alcohol use. These findings are consistent with research conducted with White/mixed groups and align with tenets of the self-medication model of PTSD-AUD comorbidity. These findings support current practices that highlight the importance of screening for and addressing PTSD and alcohol use in individuals exposed to trauma. Findings from this paper provide initial data on understudied relationships in an underserved sample and several suggestions are made to generate future research and improve clinical care for Black/AA adults.

Objective: Heightened rates of posttraumatic stress disorder (PTSD) symptoms and alcohol use have been documented among firefighters. Emotion regulation difficulties (ERD) are clinically relevant to both PTSD and alcohol use. Few studies have examined the role of ERD in the association of PTSD symptoms with alcohol use severity and alcohol use motives among firefighters. Thus, the present investigation examined the indirect effect of PTSD symptom severity on alcohol use severity and alcohol use motives through ERD.

Methods: The sample was comprised of 685 firefighters (Mage = 38.65, SD = 8.57, 93.6% male) recruited from an urban fire department in the southern U.S. to complete an online survey. Indirect effects were calculated using 10,000 bootstrapped samples. Effects were examined after accounting for years of fire service, occupational stress, trauma load (i.e., number of traumatic event types experienced); in models evaluating alcohol use motives as outcomes, other alcohol use motives (i.e., alternate motives subscales) were included as additional covariates.

Results: First, ERD explained the association of PTSD symptom severity with alcohol use coping motives (β = .01, SE = .003, 95% CI [.004-.01]). Furthermore, ERD did not significantly account for the association of PTSD symptom severity with alcohol use severity (β = .02, SE = .01, 95% CI [-.004-.04]), alcohol use enhancement motives (β = -.003, SE = .002, 95%CI [-.007-.000]), alcohol use social motives (β = .004, SE = .002, 95% CI [-.000-.01]), or alcohol use conformity motives (β = -.002, SE = .002, 95% CI [-.006-.02]).

Conclusions: Results demonstrated that, among firefighters, PTSD symptom severity is positively related to alcohol use coping motives through heightened ERD. Clinical implications and future directions are discussed.
