RESUMEN

Histone variants provide versatility in the basic unit of chromatin, helping to define dynamic landscapes and cell fates. Maintaining genome integrity is paramount for the cell, and it is intimately linked with chromatin dynamics, assembly, and disassembly during DNA transactions such as replication, repair, recombination, and transcription. In this review, we focus on the family of H3 variants and their dynamics in space and time during the cell cycle. We review the distinct H3 variants' specific features along with their escort partners, the histone chaperones, compiled across different species to discuss their distinct importance considering evolution. We place H3 dynamics at different times during the cell cycle with the possible consequences for genome stability. Finally, we examine how their mutation and alteration impact disease. The emerging picture stresses key parameters in H3 dynamics to reflect on how when they are perturbed, they become a source of stress for genome integrity.

RESUMEN

Recent national estimates suggest that 1 in 2 women will experience intimate partner violence (IPV) in their lifetime. Given the high prevalence of posttraumatic stress disorder (PTSD) among women experiencing IPV, it is necessary to consider whether PTSD assessments function adequately for this population. Thus, the present study aimed to evaluate the psychometric properties of the past-month version of the PTSD Checklist for DSM-5 (PCL-5), one of the most widely used self-report measures of PTSD symptoms, in a sample of community women experiencing IPV. Participants were 158 women who had experienced IPV in the past 6 months (Mage = 40.14 years, 39.9% White). The PCL-5 demonstrated good internal consistency, Cronbach's α = .97, and scores were significantly positively correlated with theoretically related constructs (i.e., PTSD symptom count on the SCID-5, IPV severity, substance use, depression, anxiety, and emotion dysregulation); however, it demonstrated poor 30-day stability, r = .38, ICC = .55. The ability of the PCL-5 to discriminate with respect to a PTSD diagnosis was acceptable, AUC = .74. A cutoff score of 21 maximized sensitivity (82.5%) and specificity (55.4%); this is lower than typical cutoffs (i.e., 31-33). Although the PCL-5 has generally demonstrated adequate psychometric properties, findings suggest that it does not function optimally for women experiencing IPV relative to its functioning for other trauma-exposed populations. The lower-than-typical cutoff suggests that the PCL-5 may underestimate PTSD prevalence among women experiencing IPV.

RESUMEN

Individuals with posttraumatic stress symptoms (PTSS) report difficulties engaging with positive autobiographical memories. Extending this line of research, we examined daily-level concurrent and lagged associations between PTSS severity and positive memory characteristics (vividness, coherence, accessibility, time perspective, sensory details, visual perspective, emotional intensity, sharing, distancing, and valence). The sample included 88 trauma survivors (Mage = 39.89 years, 59.1% female) who completed seven daily measures of PTSS and positive memory characteristics. Multilevel models examined concurrent and lagged associations between PTSS severity and positive memory characteristics. The results indicated that days with higher PTSS severity were associated with less accessibility, ß = -.21, p < .001; less visual perspective, ß = -0.13, p = .034; and lower positive valence of the memory, ß = -.19, p = .003, as well as more emotional intensity associated with, ß = .13, p = .041, and more distancing from, ß = .21, p < .001, the memory. Supplemental lagged analyses indicated that higher previous-day PTSS severity was associated with more next-day distancing from, ß = .15, p = .042, and sensory details of, ß = .17, p = .016, the memory. Findings suggest that individuals with more severe PTSS have difficulties accessing positively valenced memories from a first-person perspective, are more distant from the recalled positive memory, and report more emotional intensity when retrieving the memory. Thus, improving access to and reducing distance from positive autobiographical memories, as well as addressing emotional intensity surrounding the retrieval of these memories, may be potential clinical targets for PTSS interventions.

RESUMEN

BACKGROUND: Evidence links posttraumatic stress disorder (PTSD) symptoms and features of positive autobiographical memories (accessibility, vividness, coherence, sharing, emotional intensity, distancing). There is a knowledge gap on how adverse childhood experiences (ACEs) and benevolent childhood experiences (BCEs) may influence these relationships. OBJECTIVES: The current study explored whether the number ACEs or BCEs moderated associations between PTSD symptom severity and features of positive autobiographical memories. DESIGN AND METHODS: The sample included 124 student military veterans who had experienced a trauma (Mage = 33.90; 77.4% male; 75.0% White). RESULTS: Path analyses showed more PTSD symptom severity was significantly associated with less positive autobiographical memory vividness (ß = -0.26, p = .019, R2 = 0.06). Further, the number of ACEs moderated the relationship between PTSD symptom severity and positive autobiographical memory accessibility (ß = -0.25, p = .023, R2 = 0.10) and vividness (ß = -0.20, p = .024, R2 = 0.10). Among individuals with more ACEs (1 SD above the mean) compared to those with fewer ACEs (1 SD below the mean), less accessibility and vividness of positive autobiographical memories was associated with greater PTSD symptom severity. The number of BCEs was not a significant moderator. CONCLUSIONS: Positive memory-based interventions may be particularly useful to address PTSD symptoms among military veterans with a history of childhood adversity.

RESUMEN

Background: Minoritized racial/ethnic and sex assigned at birth/gender groups experience disproportionate substance-related harm. Focusing on reducing substance-related harm without requiring abstinence is a promising approach.Objectives: The purpose of this meta-epidemiologic systematic review was to examine inclusion of racial/ethnic and sex assigned at birth/gender in published studies of nonabstinence-inclusive interventions for substance use.Methods: We systematically searched databases (PubMed and PsycINFO) on May 26, 2022 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Articles were eligible for inclusion if they: 1) reported in English language, 2) had a primary goal of investigating a nonabstinence-inclusive intervention to address substance use, 3) used human subjects, and 4) only included adults aged 18 or older. Two coders screened initial articles and assessed eligibility criteria of full text articles. A third consensus rater reviewed all coding discrepancies. For the remaining full-length articles, an independent rater extracted information relevant to study goalsResults: The search strategy yielded 5,759 records. 235 included articles remained. Only 73 articles (31.1%) fully reported on both racial/ethnic and sex assigned at birth/gender, and only seven articles (3.0%) reported subgroup analyses examining treatment efficacy across minoritized groups. Nine articles (3.8%) mentioned inclusion and diversity regarding both racial/ethnic and sex assigned at birth/gender in their discussion and four articles (1.7%) broadly mentioned a lack of diversity in their limitationsConclusion: Findings highlight that little is known about nonabstinence-inclusive interventions to address substance use for individuals from minoritized racial/ethnic and sex assigned at birth/gender groups.

RESUMEN

Objective: Women of Color (WoC) experiencing intimate partner violence (IPV) have elevated rates of posttraumatic stress disorder (PTSD) and alcohol use and related harm (e.g., increased alcohol use and negative consequences). This secondary data analysis assessed the role of racial microaggressions in the association between PTSD and alcohol use and related harm among WoC experiencing IPV. Methods: Participants were 103 WoC currently experiencing IPV and using substances (Mage=40.39, 51.5% Black) who were recruited from the community and completed assessments of PTSD, racial microaggressions, and alcohol use and related harm. Results: Assumptions of Inferiority (e.g., intelligence; B = 1.44, SE = 0.90, 95% CI [0.10, 3.54]) and Environmental Microaggressions (e.g., portrayal in media; B = 1.88, SE = 1.03, 95% CI [0.28, 4.30]) explained the association between PTSD and alcohol use and related harm. Conclusions: Findings underscore the influence of specific microaggressions in the relation between PTSD and alcohol use and related harm among WoC experiencing IPV.

RESUMEN

OBJECTIVE: Borderline and antisocial personality disorders are characterized by pervasive psychosocial impairment, disproportionate criminal justice involvement, and high mental health care utilization. Although some evidence suggests that systemic bias may contribute to demographic inequities in criminal justice and mental health care among persons experiencing these mental health conditions, no research to date has explicitly examined such differences. HYPOTHESES: Women and White persons would be more likely to endorse internalizing symptoms and have a more extensive history of mental health service utilization, whereas men, persons from minoritized racial groups, and persons identifying as Hispanic/Latino would be more likely to endorse externalizing symptoms and have more extensive histories of involvement with the criminal justice system. METHOD: This study examined gender, racial, and ethnic differences in symptom presentation, criminal justice history, and mental health care utilization in a sample of 314 adults with comorbid borderline and antisocial personality disorders enrolled in prison-based substance use treatment programs in the United States. RESULTS: Results suggested that men with these personality disorders were more likely to have early extensive criminal justice involvement, whereas women and White people had more extensive mental health treatment histories. Women were also more likely to endorse a range of internalizing symptoms, and White and non-Hispanic participants were more likely to endorse a history of reckless behavior. Notably, however, many associations-particularly, racial differences in symptom presentation and mental health utilization history and gender differences in symptom presentation-did not persist after we controlled for preincarceration employment and educational attainment. CONCLUSION: Results highlight a range of gender, racial, and ethnic inequities in criminal justice involvement and mental health utilization among this high-risk high-need population. Findings attest to the likely impact of societal, structural, and systemic factors on trajectories of persons affected by this comorbidity.

RESUMEN

BACKGROUND AND OBJECTIVES: Hazardous substance use is a major public health concern among individuals with a history of sexual victimization. Although increased religiosity has been known to serve as a protective factor against hazardous substance use, religious individuals with a history of sexual victimization may be at a greater risk for hazardous substance use due to difficulties reconciling sexual victimization with their religious beliefs. Individuals with greater trauma-related shame may engage in hazardous substance use as a means of coping with the traumatic event. METHOD: The present study consisted of 614 participants (Mage = 34.57, 50% women). RESULTS: Results suggested that organizational, nonorganizational, and intrinsic religiosity were positively associated with hazardous alcohol use at higher, but not lower, levels of trauma-related shame. Organizational and intrinsic religiosity were positively associated with hazardous drug use at higher, but not lower, levels of trauma-related shame. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: This is the first study to examine the role of trauma-related shame in the relationship between religiosity and hazardous substance use. The findings underline the importance of targeting trauma-related shame in religious individuals with a history of sexual victimization.

RESUMEN

ABSTRACT: Emotion dysregulation is implicated in the development, maintenance, and treatment of sleep disturbances and posttraumatic stress disorder (PTSD) separately. However, few studies have assessed interactions among these variables. To address this gap, this study examined whether the associations of sleep quality and sleep quantity with PTSD severity were stronger at higher levels of negative and positive emotion dysregulation in a community sample of 199 trauma-exposed individuals. This study found that both poorer sleep quality and lower sleep quantity were associated with greater PTSD severity at low to average (but not high) levels of negative emotion dysregulation. Positive emotion dysregulation did not moderate the relationships between sleep quality or quantity and PTSD severity. Exploratory additive multiple moderation analyses showed significant associations between poorer sleep quality and lower sleep quantity with greater PTSD severity at low to average levels of negative emotion dysregulation, coupled with any level of positive emotion dysregulation. Findings inform theoretical perspectives on the sleep-PTSD relationship and clinical applications of targeting emotion dysregulation in the treatment of sleep disturbances and PTSD symptoms for trauma-exposed individuals.

RESUMEN

BACKGROUND: Constrictive pericarditis (CP) is an uncommon disease that limits both cardiac relaxation and contraction. Patients often present with right-sided heart failure as the pericardium thickens and impedes cardiac filling. Pericardiectomy is the treatment of choice for improving hemodynamics in CP patients; however, the procedure carries a high morbidity and mortality, and the anesthetic management can be challenging. Acute heart failure, bleeding and arrhythmias are all concerns postoperatively. METHODS: After IRB approval, we performed the retrospective analysis of 66 consecutive patients with CP who underwent pericardiectomy from July 2018 to May 2022. RESULTS: Most patients had significant preoperative comorbidities, including congestive hepatopathy (75.76%), New York Heart Association Type III/IV heart failure (59.09%) and atrial fibrillation (51.52%). Despite this, 75.76% of patients were extubated within the first 24 h and all but 2 of the patients survived to discharge (96.97%). CONCLUSIONS: Anesthetic management, including a thorough understanding of the pathophysiology of CP, the use of advanced monitoring and transesophageal echocardiography (TEE) guidance, all played an important role in patient outcomes.

RESUMEN

Interpersonal violence and opioid use disorder are significant and intersecting public health concerns in the USA. The current study evaluated the consequences associated with opioid use (e.g., physical, social, interpersonal, intrapersonal, and impulse control) as a function of a history of exposure to interpersonal trauma, specifically physical and sexual violence. Participants were 84 trauma-exposed individuals recruited from the community who use opioids (M age = 43.5 50% men; 55% white). Whereas no significant differences emerged in the consequences of opioid use based on a history of physical violence, individuals with a history of sexual violence demonstrated higher levels of impulsive consequences of opioid use compared to individuals without a history of sexual violence. These data highlight the importance of considering the role of exposure to sexual violence in the context of opioid use disorder treatment.

RESUMEN

OBJECTIVES: Research has demonstrated links between autobiographical memory retrieval and hazardous substance use. However, limited work has examined relations between positive autobiographical memories and hazardous substance use, as well as moderating factors influencing these relations. Thus, we examined the potential moderating roles of negative and positive emotion dysregulation in the relations between count of retrieved positive memories and hazardous substance use (alcohol and drug use separately). METHODS: Participants were 333 trauma-exposed students (Mage = 21.05; 85.9% women) who completed self-report measures assessing positive memory count, hazardous alcohol and drug use, negative emotion dysregulation, and positive emotion dysregulation. RESULTS: Positive emotion dysregulation significantly moderated the association between positive memory count and hazardous alcohol use (b = 0.04, 95% confidence interval [CI] [0.01, 0.06], p = 0.019), as well as the association between positive memory count and hazardous drug use (b = 0.02, 95% CI [0.01, 0.03], p = 0.002). Individuals with more positive emotion dysregulation had stronger associations between increases in positive memory count and increased hazardous substance use. CONCLUSION: Findings indicate that trauma-exposed individuals who retrieve more positive memories and experience difficulties regulating positive emotions report greater hazardous substance use. Positive emotion dysregulation may be an important target for memory-based interventions among trauma-exposed individuals who report hazardous substance use.

RESUMEN

Processing of Positive Memories Technique (PPMT) was proposed as a novel intervention for posttraumatic stress disorder (PTSD). PPMT comprises of 5 sessions focused on identifying and processing positive memories. As an open label pilot study, we explored PPMT's effects on PTSD severity, depression severity, affect and cognitive processes, and therapeutic alliance. A sample of 12 trauma-exposed participants seeking services at a University Psychology Clinic participated in 5 PPMT sessions (Mage=29.25 years; 58.30% women). We used the reliable change indices and clinically significant change score approach. The following number of participants showed statistically reliable changes: 9 participants for PTSD severity (8 recovered/improved); 6 participants for depression severity (5 improved); 5 participants for positive affect levels (2 recovered/improved); 9 participants for negative affect levels (8 recovered); 9 participants for posttrauma cognitions (7 recovered/improved); 5 participants for positive emotion dysregulation (4 recovered); 11 participants for number of retrieved positive memories (3 recovered); and 5 participants for therapeutic alliance (4 recovered). PPMT may impact certain posttrauma targets more effectively (PTSD, depression, negative affect, posttrauma cognitions). PPMT may be more helpful in improving regulation rather than levels of positive affect. PPMT, if supported in further investigations, may add to the clinician tool-box of PTSD interventions.

RESUMEN

Recently, a five-session Processing of Positive Memories Technique (PPMT) was proposed as a novel intervention for posttraumatic stress disorder (PTSD). One purported outcome of and mechanism underlying PPMT's effects on PTSD is improved positive affect processes. In this uncontrolled pilot study, we examined whether PPMT was associated with decreases in PTSD severity; and whether changes in positive affect levels, reactivity, and dysregulation related to changes in PTSD severity across sessions. The sample included 16 trauma-exposed participants seeking services at a University Psychology Clinic (Mage=27.44 years; 68.80% women). Multilevel linear growth models examined the main effects of each positive affect variable and their interactions with time on PTSD severity. PTSD severity decreased across PPMT treatment in each model (bs=-0.43 to -0.33; d=-0.03; ps<.001-0.008). There was a main effect of positive emotion dysregulation (b=1.16, d=0.11; p=0.009), but not of positive affect levels (p=0.821) or reactivity (p=0.356) on PTSD severity. However, positive affect processes did not modify the trajectory of PTSD severity across treatment. Regarding PTSD symptom clusters, there was an interaction between positive affect levels and time on alterations in arousal and reactivity (AAR) cluster severity (b=-0.01, p=0.036); individuals with positive affect levels 1 SD above the mean (b=-0.18, p<0.01) and at the mean (b=-0.10, p=0.01) had greater decreases in AAR cluster severity across treatment compared to individuals with positive affect levels 1 SD below the mean (b=-0.02, p=0.710). Findings suggest that PPMT may relate to improved PTSD symptoms; and that positive affect levels/dysregulation may be worthwhile targets for future investigations.

RESUMEN

BACKGROUND: Rates of both depression and alcohol use are disproportionately higher among American Indian (AI) adolescents than adolescents in the general population. The co-occurrence of depression and alcohol use is common and clinically relevant given their reciprocal negative influences on outcomes. Family factors may be especially relevant because they could have a buffering effect on this relationship due to the importance of kinship and community in AI communities. The current study examines the roles of family warmth and parental monitoring in the association between depressive symptoms and alcohol use in a large, nationally representative sample of AI adolescents. METHODS: Data were collected from 3498 AI 7th to 12th graders (47.8% female) residing on or near a reservation during the period 2009 to 2013. Participants reported on their depressive symptoms, family factors, and alcohol use. RESULTS: There was a small, but statistically significant positive association between depressive symptoms and alcohol use (r = 0.11, p < 0.001). Greater depressive symptoms were associated with significantly less perceived family warmth (ß = -0.09, 95% CI [-0.13, -0.06]), which was associated with significantly greater alcohol use (ß = -0.39, 95% CI [-0.55, -0.23]). Family warmth significantly accounted for the association between depressive symptoms and alcohol use at high (ß = 0.04, SE = 0.02, 95% CI [0.004, 0.09]), but not low, levels of parental monitoring (ß = 0.02, SE = 0.02, 95% CI [-0.002, 0.06]). CONCLUSIONS: Results of the present study suggest that developing culturally sensitive prevention and treatment approaches focusing on increasing both family warmth and parental monitoring are important to address the co-occurrence of depression and alcohol misuse among AI adolescents.

RESUMEN

BACKGROUND: American Indian (AI) adolescents report disproportionate higher rates of alcohol use and alcohol-related consequences than adolescents from other racial/ethnic groups. Trauma exposure is also reported at high rates among AI individuals and likely confers risk for alcohol use. The purpose of the present study was to examine the effects of assaultive trauma experiences (e.g., physical assault, sexual assault) on alcohol use and alcohol-related consequences in AI adolescents. METHODS: We conducted a secondary analysis of self-reported data on trauma exposure, alcohol consumption, and lifetime alcohol-related consequences provided by AI 7th to 12th graders residing on or near a reservation (n = 3498, Mage  = 14.8; 49.5% female). Institutional Review Boards, tribal authorities, and school boards approved the study protocols prior to beginning data collection. RESULTS: Nearly half (49.3%, n = 1498) of AI adolescents reported having experienced at least one assaultive trauma in their lifetime. Those who had experienced assaultive trauma were more likely to report lifetime alcohol use (χ2  = 111.84, p < 0.001) and experienced greater alcohol-related consequences (t(1746) = 12.21, p < 0.001) than those with no assaultive trauma exposure. Multilevel regression analyses indicated that a greater number of assaultive traumatic events was significantly associated with greater odds of lifetime alcohol use (p < 0.001, OR = 1.81, 95% CI [1.65, 2.00]) and having experienced a greater number of alcohol-related consequences (b = 0.36, SE = 0.04, t = 16.95, p < 0.001, 95% CI [0.31, 0.46]). CONCLUSIONS: Findings of the present study highlight the relevance of exposure to assaultive trauma to AI adolescents' use of alcohol and experiences of alcohol-related consequences. These findings support the need for trauma-informed interventions in addressing alcohol use among AI adolescents.

RESUMEN

BACKGROUND: Research examining emotion dysregulation and alcohol use has increased exponentially over the past decade. However, these studies have been limited by their use of cross-sectional designs and narrow definitions of emotion dysregulation. To address these significant gaps in the extant literature, this study utilized state-of-the-art methodology (i.e., experience sampling) and statistics (i.e., dynamic structural equation modeling) to examine potential reciprocal associations between negative and positive emotion dysregulation and alcohol use at the momentary level. METHODS: Participants were 145 community women (mean age = 40.56, 40.3% white) experiencing intimate partner violence (IPV) and using substances. Surveys assessing negative and positive emotion dysregulation and alcohol use (i.e., number of standard drinks) were administered three times a day for 30 days using phone-based interactive voice recording. RESULTS: Significant contemporaneous effects indicated that negative and positive emotion dysregulation both co-occurred with alcohol use. However, levels of negative and positive emotion dysregulation did not predict later alcohol use, nor did alcohol use predict later levels of negative or positive emotion dysregulation. There was significant variability among participants in cross-lagged effects. CONCLUSIONS: Findings showed that negative and positive emotion dysregulation co-occurred with alcohol use and that there was significant interindividual variability in the cross-lagged associations between negative and positive emotion dysregulation and alcohol use. Research using idiographic approaches may identify women experiencing IPV for whom negative and positive emotion dysregulation drive alcohol use and alcohol use drives negative and positive emotion dysregulation.

RESUMEN

BACKGROUND AND OBJECTIVES: Anxiety sensitivity, or fear of anxious arousal, may be an important risk factor for problematic cannabis use. Specifically, anxiety sensitivity may motivate cannabis use to cope with distress, particularly among trauma-exposed individuals. The current study tested associations among anxiety sensitivity, its subdomains, and cannabis use motives in a sample of trauma-exposed cannabis users. We hypothesized elevated anxiety sensitivity, particularly cognitive concerns, would be associated with increased maladaptive coping use motives, after covarying for the number of traumas and cannabis use quantity. METHOD: Hypotheses were tested in a cross-sectional study of trauma-exposed young adult cannabis users (N = 56) (Mage = 20.7 years, 59% women, 73% white). Participants completed self-report measures, and a clinical interview assessing cannabis use quantity. RESULTS: Multiple regression analyses indicated that elevated anxiety sensitivity was associated with increased cannabis use coping motives, after covarying for the number of traumas experienced and cannabis use quantity. Specifically, higher levels of anxiety sensitivity cognitive and social concerns were associated with coping motives for cannabis use. DISCUSSION AND CONCLUSIONS: Anxiety sensitivity, particularly concerns about cognitive dyscontrol and negative social evaluations of anxious arousal, may motivate cannabis use to cope with stress among trauma-exposed cannabis users. Future research should include prospective studies with diverse samples to replicate results and determine whether intervening on anxiety sensitivity could reduce maladaptive coping motives for cannabis use. SCIENTIFIC SIGNIFICANCE: The current study replicates prior research indicating anxiety sensitivity, particularly cognitive concerns, is associated with maladaptive cannabis use. Expanding on prior research, findings indicated anxiety sensitivity is associated with coping motives for cannabis use among trauma-exposed cannabis users.

RESUMEN

BACKGROUND: Research on associations between social integration and wellbeing holds promise to inform policy and practice targets for health promotion. Yet, studies of social connection too frequently rely on overly simplistic measures and give inadequate attention to manifestation and meanings of social integration across diverse groups. We use the term socio-cultural integration to describe expanded assessment of both social and cultural aspects of belonging and connection. METHODS: We examined 7 distinct indicators of socio-cultural integration, identified heterogeneous patterns of responses across these indicators using latent profile analysis, and determined their relevance for wellbeing using survey data from a study with Indigenous communities in the U.S. and Canada. Wellbeing was measured using holistic ratings of self-rated physical, emotional, and spiritual health. RESULTS: Latent profile analysis (LPA) of responses to the 7 socio-cultural integration variables yielded a 3-class model, which we labeled low, moderate, and high integration. Mean scores on self-rated physical, mental and spiritual health were significantly associated with LPA profiles, such that those in the low integration group had the lowest self-rated health scores and those in the high integration group had the highest health scores. With the exception of similar ratings of cultural identification between low and moderate integration profiles, patterns of responses to the diverse socio-cultural integration measures varied significantly across the 3 latent profiles. CONCLUSIONS: Results underscore the importance of expanding our assessment of social integration with attention to the interrelationships of family, community, culture, and our environment. Such concepts align with Indigenous conceptions of wellbeing, and have relevance for health across cultures. More concretely, the indicators of socio-cultural integration used in this study (e.g., cultural identity, having a sense of connectedness to nature or family, giving or receiving social support) represent malleable targets for inclusion in health promotion initiatives.

RESUMEN

Given the disproportionate rate of alcohol misuse among veterans and related outcomes as compared to the general population, the examination of predictors of alcohol misuse in this population is imperative. Potentially morally injurious events (PMIEs), defined as severe transgressions of a moral code, have been positively associated with alcohol misuse. Exposure to PMIEs may challenge one's religious beliefs, which may, in turn, influence the strength of the association between PMIEs and alcohol misuse among military veterans. The goal of the current study was to examine the potential moderating role of religiosity in the association between PMIEs and alcohol misuse (i.e., alcohol consumption, drinking behaviors, adverse reactions to drinking, and alcohol-related problems). Participants were 496 military veterans in the community (Mage = 37.80 years, SD = 11.42; 70.5% male). The results of moderation analyses indicated that overall religiosity, organizational religiosity, and intrinsic religiosity significantly moderated the association between PMIEs and alcohol misuse such that the positive relation between PMIEs and alcohol misuse was stronger at high versus low levels of religiosity, R2 s = .01. Our findings highlight the importance of considering the role of religiosity in relation to alcohol misuse as a moral injury outcome and the potential utility of tailoring treatments for military veterans who have experienced moral injury.
