Longitudinal examination of borderline personality disorder symptoms and drug use: The influence of negative and positive emotion dysregulation.

Borderline personality disorder (BPD) is associated with greater substance use. Emotion dysregulation has been implicated in both BPD and substance use, yet there is limited research examining the role of emotion dysregulation in the BPD-substance use relation. We examined the independent and interactive associations of BPD symptoms and emotion dysregulation in reported drug use over 1 year. Participants (N = 143) were over-recruited for BPD, assessed via interview, and completed measures of negative and positive emotion dysregulation. Drug use frequency was assessed with monthly surveys over a 1-year period. Results demonstrated interrelations among BPD symptoms and both negative and positive emotion dysregulation. However, when modeling BPD and emotion dysregulation together, only higher BPD symptoms were associated with more frequent drug use. Findings support the relation of BPD symptoms and emotion dysregulation but suggest that emotion dysregulation may not account for drug use frequency above and beyond BPD in community-recruited populations.

Concordance of Posttraumatic Stress Disorder Symptoms Assessed via Retrospective Report Versus Experience Sampling Methods in Community Women Experiencing Intimate Partner Violence.

Posttraumatic stress disorder (PTSD) is one of the most prominent negative health consequences that women experiencing intimate partner violence (IPV) may develop. However, research on PTSD among women experiencing IPV has largely relied on retrospective reporting methods, which are vulnerable to bias and may consequently misrepresent PTSD symptoms. This study evaluated the concordance between PTSD symptoms assessed via retrospective self-report and experience sampling methods (ESM), which involve repeated within-day sampling of experiences in near real-time and in natural environments. Community women (N = 134) experiencing IPV (Mage = 40.7, 30.4% Black) responded to ESM surveys three times a day for 30 days and then completed a follow-up interview. Retrospective self-report of PTSD symptoms, which were assessed during the follow-up interview, were compared to ESM reports of PTSD symptoms. Retrospective reports of PTSD symptoms were significantly different from PTSD symptoms reported during the ESM period, but most closely resembled peak PTSD symptoms. Notably, retrospective reports of PTSD symptoms were significantly different, with a very large effect size, from average PTSD symptoms reported during the ESM period. Discordance scores were significantly negatively associated with the number of days on which any IPV occurred, suggesting that as the frequency of IPV experiences increased, differences between retrospective PTSD symptoms and each ESM symptom pattern decreased. This study provides an important contribution to the literature by highlighting meaningful differences in PTSD symptoms assessed via retrospective self-report versus ESM and the role of IPV context. Findings emphasize the importance of utilizing ESM in PTSD research with women experiencing IPV.

Role of Alexithymia in the Association Between Childhood Abuse and Risk Perception for Sexual Victimization in College Women.

Sexual victimization is prevalent among college women with a history of childhood abuse (CA), which some research suggests is linked to impaired risk perception for sexual victimization or difficulties identifying and responding to unwanted sexual advances. Alexithymia is one construct yet to be examined in the association between CA and risk perception for sexual victimization. The purpose of this study was to elucidate the associations between CA, alexithymia, and risk perception for sexual victimization in a sample of college women with a history of CA. Participants included 294 undergraduate women with a history of childhood emotional, physical, and/or sexual abuse (Mage = 20.6, 80.6% White). An a priori path analysis was conducted to examine whether alexithymia indirectly explains the association between CA and risk perception for sexual victimization (i.e., comprising two related constructs, including threat detection and behavioral response to threat). Supplementary analyses were conducted post hoc to examine potential differences across CA subtypes (emotional, physical, and sexual). Alexithymia indirectly explained the relationship between CA and threat detection, and behavioral response to threat. However, indirect effects were negative, suggesting that undergraduate women with more severe CA and alexithymia identify sexual assault threat cues and intentions to "leave" a hypothetical sexual assault scenario sooner rather than later. The same pattern of results was observed for emotional and physical (but not sexual) CA when examining their indirect effects on threat detection, and for emotional CA when examining behavioral response to threat. Findings contribute to the literature on sexual victimization by clarifying the role of alexithymia in risk perception for sexual victimization. Results also highlight the potential utility of increasing emotional literacy among college women with a history of CA (and especially emotional abuse) to facilitate adaptive responding to unwanted sexual advances.

Ground-up approach to understanding the impacts of historical trauma in one reserve-dwelling first nations community.

OBJECTIVE: First Nations peoples experience disproportionate health inequities compared to most non-Indigenous populations. Historical trauma is one factor that has received growing attention in relation to health inequities among First Nations populations. The goal of the present study was to improve understanding of the specific forms, impacts, and mechanisms of transmission of events that lead to historical trauma and the historical trauma response in First Nations peoples. METHOD: Five focus groups were conducted among adult members of one First Nations community in Canada (N = 34; 70.4% female). RESULTS: Conventional content analysis revealed the numerous forms that historical trauma take in this First Nations community; individual-, familial-, community-, and societal-level impacts of historical trauma; and ways in which historical trauma has been transmitted in this community. Loss of culture, alcohol use, and parenting were major themes identified across these domains. CONCLUSIONS: Findings provide important information on the experience of historical trauma in one First Nations community, highlighting the roles of loss of culture; alcohol use; and parenting in the forms, impacts, and transmission of historical trauma.

Experimental Investigation of the Influence of Positive Emotion Dysregulation on Risky Behavior Following Idiographic Emotion Inductions.

An experimental paradigm with subjective and objective assessments was used to further explicate the role of positive emotion dysregulation on risky behavior. Participants were 151 community women currently experiencing intimate partner violence and using substances (Mage = 40.81, 43.0% white). Participants were randomly assigned to positive, negative, and neutral idiographic emotion inductions. Subjective (state self-report) and objective (high frequency heart rate variability [hfHRV], skin conductance response, and salivary cortisol) markers of emotion dysregulation were assessed, following which participants completed subjective (state urges for substances) and objective (Balloon Analogue Risk Task) measures of risky behavior. Results showed (a) greater self-reported state emotion dysregulation and lower hfHRV predicted more urges for substances in the positive (versus negative and neutral) emotion induction conditions; and (b) lower hfHRV predicted more behavioral risk-taking propensity in the positive (versus neutral) emotion induction condition. Findings provide additional support for the influence of positive emotion dysregulation on risky behavior.

The Posttraumatic Stress Disorder (PTSD) Checklist for DSM-5: A Systematic Review of Existing Psychometric Evidence.

The PTSD Checklist for DSM-5 (PCL-5) is a widely used self-rated measure of DSM-5 PTSD symptoms. The goal of this systematic review was to synthesize research on the psychometric properties of the PCL-5 to guide clinical and research applications. We focused on reliability, validity, factor structure, optimal cutoff scores, and sensitivity to clinical change indices. A systematic review of the literature following PRISMA guidelines was conducted using PubMed, PsycINFO, CINAHL, and PTSDpubs with search terms capturing selected psychometric indices of the PCL-5. The inclusion criteria were: peer-reviewed publication in English; primary focus on the PCL-5 psychometrics; empirical study; and study with adult samples. The search yielded 265 studies; 56 papers (amounting to 64 studies) met inclusion criteria and were reviewed. Findings generally indicated evidence for: acceptable internal consistency and test-retest reliability; construct validity; a 7-factor Hybrid Model; recommended cutoff scores between 31-33; and ability to index sensitivity to clinical change. To further advance knowledge and applications of the PCL-5, we need more research on abbreviated versions of the PCL-5, bifactor modeling as applied to the PCL-5, as well as on PCL-5 item difficulty estimates, discrimination parameters, and clinical change score estimates.

Emotion dysregulation as a mechanism linking posttraumatic stress disorder to subsequent suicidal thoughts and behaviors following inpatient psychiatric discharge.

Posttraumatic stress disorder (PTSD) is a well-known risk factor for suicidal thoughts and behaviors (STBs). However, there is a scarcity of longitudinal studies exploring underlying pathways. This study sought to examine the mechanistic role of emotion dysregulation in the relations between PTSD and STBs following discharge from psychiatric inpatient treatment, a particularly high-risk period for suicide. Participants were 362 trauma-exposed psychiatric inpatients (45% female, 77% white, Mage = 40.37). PTSD was assessed via a clinical interview (Columbia Suicide Severity Rating Scale) during hospitalization, emotion dysregulation was assessed via self-report 3-weeks post-discharge, and STBs were assessed via a clinical interview 6-months post-discharge. St'1ructural equation modeling showed that emotion dysregulation significantly mediated the relation between PTSD and suicidal thoughts (ß = 0.10, SE = 0.04, p = .01, 95%CI [0.04, 0.39]) but not suicide attempts (ß = 0.04, SE = 0.04, p = .29, 95%CI [-0.03, 0.12]) post-discharge. Findings highlight a potential clinical utility of targeting emotion dysregulation among individuals with PTSD to prevent suicidal thoughts following discharge from psychiatric inpatient treatment.

The influence of trauma-related shame on the associations between posttraumatic symptoms and impulsivity facets.

INTRODUCTION: The co-occurrence of posttraumatic symptoms (PTS) and impulsivity is associated with higher levels of risky and self-destructive behaviors and consequent safety and health risks. Trauma-related shame (TRS) may influence the association between PTS and impulsivity such that engaging in impulsive behaviors may serve to cope with emotional distress. Alternatively, TRS may motivate a deliberate consideration of behaviors (i.e., less impulsivity) to prevent further cognitive and emotional distress. OBJECTIVE: The goal of the current study was to examine the influence of TRS on the associations between PTS and impulsivity facets (lack of premeditation, lack of perseverance, negative urgency, positive urgency, sensation seeking). METHOD: Data were collected from 506 community individuals who endorsed lifetime sexual trauma (Mage = 34.56, 54.3% women, 78.7% White). RESULTS: Findings indicated that TRS moderated associations between PTS and impulsivity facets of lack of perseverance, b = -.001, SE = .0003; t = -2.68, p = .008, 95% confidence interval [-.001, -.0002], and premeditation, b = -.001, SE = .0003; t = -3.70, p < .001, [-.002, -.001]; these associations were significant at low, but not high, levels of TRS. CONCLUSIONS: Findings suggest that in the context of PTS, TRS may reduce certain forms of impulsivity, potentially as a means to self-protect against further cognitive and emotional distress. Findings have important implications for understanding how individuals regulate and respond to shame in the context of PTS. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Daily reciprocal relations between emotion dysregulation and non-suicidal self-injury among individuals with a history of sexual assault: The influence of posttraumatic stress symptoms.

INTRODUCTION: Non-suicidal self-injury (NSSI) is a serious public health concern that can be understood within an emotion dysregulation framework. The current study adds to the literature by utilizing a micro-longitudinal design and novel statistical modeling to test reciprocal associations between emotion dysregulation and NSSI, as well as the potential moderating effect of posttraumatic stress symptoms (PTSS). METHODS: Participants were 81 individuals with a history of sexual assault and NSSI (Mage  = 33.80; 67.9% women; 80.2% white) recruited from the community who self-reported on symptoms of emotion dysregulation and NSSI thoughts/behaviors once daily for 7 days. Average compliance rate was 72.8% (SD = 31.3%) and 34 participants (42.0%) endorsed NSSI thoughts/behaviors over the course of the study. RESULTS: Findings revealed a significant positive effect of NSSI thoughts/behaviors on subsequent abilities to regulate negative emotions. Furthermore, while results did not detect a moderating influence of baseline PTSS on the relation between emotion dysregulation and NSSI thoughts/behaviors over time, individuals with higher baseline PTSS were found to experience heightened levels of NSSI thoughts/behaviors and emotion dysregulation on average. CONCLUSION: Information from this study may be useful for future research and intervention development focused on the intersection of NSSI, PTSS, and emotion dysregulation.

Posttraumatic stress symptoms and risky alcohol use: The roles of negative social reactions to sexual assault disclosure and trauma-related shame.

INTRODUCTION: Posttraumatic stress symptoms (PTS) and risky alcohol use (RAU) frequently co-occur among those with a history of sexual assault, and this co-occurrence has been linked to severe psychosocial and functional impairment. OBJECTIVE: The current study examined the roles of negative social reactions to sexual assault disclosure and trauma-related shame in the association between PTS severity and RAU. This was tested by examining the separate and sequential indirect effects of negative social reactions and trauma-related shame in the PTSD-RAU relation among individuals with a history of sexual assault. METHOD: Data were collected from 235 individuals who endorsed a history of sexual assault (Mage = 35.45, 70.5% women, 83.8% White). RESULTS: Negative social reactions (b = .03, SE = .01, p < .05, 95% CI [.005, .06]) and trauma-related shame (b = .03, SE = .01, p < .05, 95% CI [.003, .06]), separately, and sequentially (b = .01, SE = .004, p < .05, 95% CI [.001, .02]) explained the relation between PTS severity and RAU. CONCLUSIONS: Findings suggest that it may be valuable to assess and neutralize negative social reactions to reduce trauma-related shame and subsequent RAU among individuals with a history of sexual assault who experience more severe PTS severity.

Posttraumatic stress disorder strengthens the momentary associations between emotion dysregulation and substance use: a micro-longitudinal study of community women experiencing intimate partner violence.

BACKGROUND AND AIMS: A fast-growing body of literature linking emotion dysregulation to substance use has almost exclusively relied on cross-sectional designs and has generally failed to assess dysregulation stemming from positive emotions. The current study measured the momentary associations between both negative and positive emotion dysregulation and substance use, as well as the moderating role of post-traumatic stress disorder (PTSD). DESIGN: Micro-longitudinal momentary data were collected three times per day for 30 days using phone-based interactive voice recording. SETTING: Northeastern United States. PARTICIPANTS: A total of 145 community women (M, age = 40.56, 40.3% white) experiencing intimate partner violence (IPV) and using substances were recruited from 2018 until 2020. MEASUREMENTS: Momentary surveys assessed negative and positive emotion dysregulation and alcohol, drug, and cigarette use. PTSD diagnosis was derived from a structured diagnostic interview. FINDINGS: Between-person relations that remained significant after covariate adjustment and correction for multiple testing were found for negative emotion dysregulation and both number of drinks (internal rate of return [IRR] = 1.45; 95% CI = 1.07, 1.93; ß = 0.37) and drug use (OR = 3.78; 95% CI = 1.86, 7.69; ß = 1.33), and positive emotion dysregulation and number of cigarettes (OR = 1.40; 95% CI = 1.07, 1.82; ß = 0.34). Of six interactions tests, PTSD was only shown to moderate the within-person relation between positive emotion dysregulation and drug use, even after controlling for relevant covariates and adjusting for multiple testing (OR = 1.26; 95% CI = 1.04, 1.51; ß = 0.23), such that women experiencing intimate partner violence with versus without PTSD were more likely to use drugs when experiencing periods of elevated positive emotion dysregulation. CONCLUSIONS: Women experiencing intimate partner violence with higher levels of negative dysregulation relative to others may use more alcohol and be more likely to use drugs. Women experiencing intimate partner violence with higher levels of positive dysregulation relative to others may use more cigarettes. Women experiencing intimate partner violence who also have posttraumatic stress disorder may be more likely to use drugs when experiencing momentary elevated levels of positive emotion dysregulation than those who do not also have posttraumatic stress disorder.

Daily reciprocal relations between negative and positive emotion dysregulation and posttraumatic stress symptoms among individuals with a history of sexual assault.

Posttraumatic stress symptoms (PTSS) are a debilitating health concern that can develop following sexual assault. One factor central to PTSS is emotion dysregulation. However, little is known about how emotion dysregulation, particularly the dysregulation of positive (versus negative) emotions, relates to the maintenance of PTSS over time. This study aimed to address this gap in the literature by using a micro-longitudinal approach to examine daily reciprocal relations between negative and positive emotion dysregulation and PTSS. Participants were 121 individuals with a history of sexual assault (Mage = 35.27; 70.2% women; 81.0% white) recruited from the community. Participants self-reported on negative and positive emotion dysregulation as well as PTSS once daily for seven days. Findings provide support for the effects of both negative and positive emotion dysregulation on increases in next-day PTSS. Results carry important implications for PTSS assessment and intervention efforts among those with a history of sexual assault.

Anxiety sensitivity and cannabis use motives among trauma-exposed young adult cannabis users.

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.

The Role of Presumed Head and Neck Injuries in Emotion Dysregulation Among Community Women With a History of Physical Intimate Partner Violence.

Intimate partner violence (IPV) is prevalent among women and associated with negative outcomes, including emotion dysregulation. Limited research has examined factors that contribute to emotion dysregulation in this population. This study explores the potential influence of presumed head and neck injuries from IPV on five dimensions of emotion dysregulation. Participants were 352 community women who responded to an online survey. Results of a path analysis indicated that presumed head and neck injuries from IPV were significantly associated with lack of emotional clarity and difficulties engaging in goal-directed behaviors when experiencing emotions. Findings suggest an association between presumed head and neck injuries from IPV and emotion dysregulation, underscoring the potential need for considering both neurological and psychological factors in the assessment and treatment of emotion dysregulation in this population.

Intimate Partner Violence and Posttraumatic Stress Symptoms: Indirect Effects Through Negative and Positive Emotion Dysregulation.

Women who experience intimate partner violence (IPV) are at heightened risk for developing posttraumatic stress (PTS). Emotion dysregulation has been linked to both IPV and PTS, separately, however, unknown is the role of emotion dysregulation in the relation of IPV to PTS among women who experience IPV. Moreover, existing investigations in this area have been limited in their focus on negative emotion dysregulation. Extending prior research, this study investigated whether physical, sexual, and psychological IPV were indirectly associated with PTS symptom severity through negative and positive emotion dysregulation. Participants were 354 women who reported a history of IPV recruited from Amazon's MTurk platform (Mage = 36.52, 79.9% white). Participants completed self-report measures assessing physical (Conflict Tactics Scale), sexual (Sexual Experiences Scale), and psychological (Psychological Maltreatment of Women) IPV; negative (Difficulties in Emotion Regulation Scale) and positive (Difficulties in Emotion Regulation Scale-Positive) emotion dysregulation; and PTS symptom severity (PTSD Checklist for DSM-5) via an online survey. Pearson's correlation coefficients examined intercorrelations among the primary study variables. Indirect effect analyses were conducted to determine if negative and positive emotion dysregulation explained the relations between physical, sexual, and psychological IPV and PTS symptom severity. Physical, sexual, and psychological IPV were significantly positively associated with both negative and positive emotion dysregulation as well as PTS symptom severity, with the exception that psychological IPV was not significantly associated with positive emotion dysregulation. Moreover, negative and positive emotion dysregulation accounted for the relationships between all three IPV types and PTS symptom severity, with the exception of positive emotion dysregulation and psychological IPV. Our findings provide support for the potential underlying role of both negative and positive emotion dysregulation in the associations of IPV types to PTS symptom severity. Negative and positive emotion dysregulation may be important factors to integrate into interventions for PTS among women who experience IPV.

Posttraumatic stress disorder symptom severity modulates avoidance of positive emotions among trauma-exposed military veterans in the community.

OBJECTIVE: Theoretical and empirical evidence links emotional avoidance to the development and maintenance of posttraumatic stress disorder (PTSD) symptoms. However, few studies have tested whether these findings extend to positive emotional avoidance. Addressing this important gap in the literature, the current study examined the moderating role of PTSD symptom severity in the relation between positive emotional intensity and positive emotional avoidance. METHOD: Participants were 465 trauma-exposed veterans recruited from the community (Mage = 38.00, 71.6% male, 69.5% White). RESULTS: The interaction between positive emotional intensity and PTSD symptom severity on positive emotional avoidance was significant. Analysis of simple slopes revealed that positive emotional intensity was significantly positively associated with positive emotional avoidance when participants endorsed high, but not low, levels of PTSD symptom severity. CONCLUSIONS: Veterans with more severe PTSD symptoms may utilize avoidance strategies in the context of intense positive emotions. These findings may suggest the potential need for addressing positive emotional avoidance in interventions to reduce PTSD symptom severity.

Emotion regulation and substance use: A meta-analysis.

There has been exponential growth in research on emotion regulation and substance use in the past decade. The current meta-analysis evaluated variability in the magnitude of the relation between aspects of emotion regulation and substance use. A search of PsycINFO, Embase, PubMed, CINAHL Plus, and PILOTS in December 2020 resulted in 6642 initial studies, of which 95 met inclusion criteria (association between emotion regulation and substance use was reported, participants were > 18 years old, article was in English). A total of 445 effects were obtained (N = 156,025 participants; weighted Mage = 29.31; 59.5% female; 66.1% White; 76.6% non-clinical). Emotion regulation and substance use were significantly related (r = 0.19; p < 0.001; 95%CI [0.17, 0.20]). Emotion regulation abilities were generally more strongly related to substance use than emotion regulation strategies; this pattern was stronger for behavioral vs. cognitive abilities and extended to both negative and positive emotions. Relations were stronger for older and clinical samples; mixed effects were found for sex and no conclusive effects were found for race. Despite limitations of the existing literature (e.g., cross-sectional, self-reports), results indicated that the magnitude of the relation between emotion regulation and substance use varied considerably as a function of emotion regulation and substance use constructs and sample characteristics.

Positive emotion dysregulation and posttraumatic stress disorder symptoms: Investigating the role of anxiety sensitivity.

OBJECTIVE: Posttraumatic stress disorder (PTSD) symptoms are prevalent and deleterious among individuals who have experienced a sexual assault. Although an emerging field of research has established a link between positive emotion dysregulation and PTSD symptoms, there is a limited understanding of mechanisms underlying this relation. Individuals who have experienced a sexual assault may begin to fear any arousal-related sensations via stimulus generalization, including that associated with positive emotions, which, in turn, may amplify PTSD symptoms. Thus, the current study examined the role of anxiety sensitivity in the association between positive emotion dysregulation and PTSD symptoms. METHODS: A sample of 500 community members reporting a history of sexual assault (Mage=34.54, 54.4% male, 79.0% white) completed measures of positive emotion dysregulation, anxiety sensitivity, and PTSD symptoms. RESULTS: Findings detected a significant indirect effect of anxiety sensitivity in the relation between positive emotion dysregulation and PTSD symptoms (ß = 0.28, SE=0.03, 95% CI [0.22, 0.34]). Supplementary analyses revealed that effects held for subscales of anxiety sensitivity (i.e., cognitive, physical, social concerns) and PTSD symptom clusters (i.e., intrusions, avoidance, negative alternations in cognitions and mood, alternations in arousal and reactivity). CONCLUSIONS: This study offers preliminary empirical support for the assertion that fear of arousal-related sensations associated with positive emotions may partially explain the link between positive emotion dysregulation and PTSD symptoms among those who have experienced a sexual assault. Information from this study could advance future research and treatment.

Positive Emotion Dysregulation Identifies Trauma-Exposed Community Individuals at Risk for Suicide and Nonsuicidal Self-Injury.

ABSTRACT: Emotion dysregulation is associated with increased risk for suicidal thoughts and behaviors (STBs) and nonsuicidal self-injury (NSSI). However, research in this area has focused almost exclusively on dysregulation stemming from negative emotions. The present study aimed to address this gap in the literature by examining the associations between the specific domains of positive emotion dysregulation and both STBs and NSSI. Participants included 397 trauma-exposed community adults (Mage = 35.95; 57.7% female; 76.8% White). Results demonstrated significant associations between positive emotion dysregulation and both STBs and NSSI. In particular, higher levels of nonacceptance of positive emotions were found to be significantly related to risk for STBs (versus no risk), higher severity of STBs, and history of NSSI (versus no history). Findings suggest positive emotion dysregulation may play an important role in the etiology and treatment of both STBs and NSSI among trauma-exposed individuals.

Alcohol to down-regulate negative and positive emotions: Extending our understanding of the functional role of alcohol in relation to posttraumatic stress disorder.

INTRODUCTION: Functional models of posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) underscore the role of internally-driven negative reinforcement. However, with the focus of these models being on negative emotions broadly, there is limited understanding of the effect of alcohol use to down-regulate specific forms of negative emotions or positive emotions generally. Among populations characterized by PTSD, there is growing evidence that positive emotions may elicit aversive reactions and thus be intentionally reduced, including via alcohol use. OBJECTIVE: The current study examined the associations among PTSD symptom severity, alcohol use to down-regulate both negative (i.e., despondency and anger) and positive emotions, and alcohol misuse. METHOD: Data were collected from 320 trauma-exposed, substance-using individuals in the community (M age = 35.78, 46.9% women). RESULTS: Individuals with greater PTSD symptom severity reported significantly higher alcohol use to down-regulate despondency, anger, and positive emotions, which, in turn, were linked to greater alcohol misuse. CONCLUSIONS: Alcohol use may serve to down-regulate both negative (i.e., despondency and anger) and positive emotions, and these functions may help to explain the association of PTSD symptom severity to alcohol misuse. PTSD-AUD models may benefit from specifying a negatively reinforcing function of alcohol use in the context of positive emotions.
