Psychometric evaluation of the Psychache Scale: A multigroup comparison between white and hispanic undergraduate student drinkers.

With psychache being an integral aspect of suicidal and addictive behavior, there is a need for efficient assessment, including generalizability across various racial and ethnic identities. Multigroup Confirmatory Factor Analysis of the Psychache Scale was conducted in the context of 1537 undergraduate college student drinkers (White = 1,171, Hispanic = 366). The alternative bifactor model was a better solution compared to other competing models suggesting that the Psychache Scale is sufficiently unidimensional. There was sufficient support for measurement invariance, which implies that the scale is measuring the same construct across groups. The Hispanic group had a significantly higher latent mean overall psychache score compared to their counterparts. The association of psychache with various adjustment outcomes was also similar across groups. The measure demonstrated robust properties to capture psychological pain. Additional studies need to be done to examine factors influencing psychache, especially among the Hispanic population.

Interpersonal communication and perceived norms as social influence mechanisms of e-cigarette use among adults: a systematic review.

Background: Given the increasing popularity of e-cigarette use among adults and the ongoing debate about the benefits and the potential adverse health risks associated with e-cigarette use, it is critical to identify the correlates of e-cigarette use. Prior research has found associations between interpersonal communication, perceived norms, and adults' e-cigarette use, but the evidence has yet to be summarized and synthesized.Objectives: This paper reviewed empirical studies examining the relationship between interpersonal communication, perceived norms, and e-cigarette use among adults.Methods: Following PRISMA guidelines, articles were searched on DOAJ, EMBASE, Europe PubMed Central, Google Scholar, PsychINFO, PubMed, Web of Science, and the reference list of the retrieved studies for studies that examined social influence on e-cigarette use. Three reviewers independently screened 1,713 non-duplicate papers and further screened the full text of 195 articles for inclusion.Results: Thirty studies (30), consisting of quantitative (n = 25) and qualitative (n = 5) data, were included in this review. The twenty-five (25) quantitative studies consisted of both cross-sectional (n = 20) and longitudinal (n = 5) studies. Interpersonal communication portraying e-cigarettes as beneficial or harmful was found to increase e-cigarette use and quit attempts, respectively. Across study designs, greater perceptions of others' e-cigarette use or approval were related to more frequent e-cigarette use.Conclusions: The findings highlight that e-cigarette-related interpersonal communication and perceived norms are associated with e-cigarette use. These factors may be useful targets in brief interventions. However, most of the included studies were cross-sectional, limiting the ability to establish clear cause-and-effect relationships; therefore, more longitudinal studies are needed.

Perceptions of Addiction Medications Within Collegiate Recovery Communities.

OBJECTIVES: Addiction medications (AM) are effective in improving recovery outcomes, but many barriers still exist that reduce their implementation among young adults. While the perception of AM has been explored within clinicians and counselors in many settings, it has not yet been documented within collegiate recovery communities (CRC). The aim of this brief report is to assess the acceptability and intent to use AM among students in recovery, and to evaluate the effect of attitudes, perceived AM effectiveness, and social norms on these outcomes. METHODS: Using the Theory of Planned Behavior, CRC students (N = 162; 44% female) within the United States completed an online survey. RESULTS: Results from a hierarchical linear model indicated that the perceived acceptance of AM use by important others was significantly related to the intent to use AM ( ß = 0.47, P < 0.01) and encourage others to use AM ( ß = 0.16, P < 0.05). Positive attitudes about AM predicted acceptability of AM use ( ß = 0.42, P < 0.01) and encouraging other CRC students to use AM ( ß = 0.38, P < 0.01). Perceived AM effectiveness was positively associated with acceptability ( ß = 0.36, P < 0.01) and encouragement of others ( ß = 0.27, P < 0.01). CONCLUSIONS: Results highlight the importance of promoting effectiveness, improving attitudes, and tapping social networks to increase AM use and acceptability among CRC students. Implications for CRC policy and programming are discussed.

A Scoping Review on the Role of Sexual Orientation and Gender Identity Microaggressions in Substance Use.

Objectives: Disparities in substance use patterns and outcomes are evident among sexual and gender minority groups. Sexual orientation and gender identity (SOGI) microaggression, or the subtle forms of aggression experienced by lesbian, gay, bisexual, transgender, gender non-conforming/non-binary, and gender diverse individuals, has recently been explored as a mechanism that leads to negative adjustment outcomes, including substance use. In this study we examined extant literature on the association between SOGI microaggression and substance use, and the intermediary factors that mediate or moderate this relationship. Method: Scoping review method was used to systematically map the literature base using database aggregators (e.g., Scopus, EBSCO) following the PRISMA Extension for Scoping Reviews (PRISMA-ScR) guidelines. Results: We found that SOGI microaggression is positively associated with substance use and negative consequences, and this relationship is mediated or moderated by motivational, relational, and identity processes. Conclusion: These findings suggest the need to consider microaggression experience when working with clients of diverse sexual and gender identities. Likewise, additional studies are needed on other intermediary factors and effects of microaggression on substances other than alcohol. Most importantly, this study underscores the need for understanding the link between microaggression and substance use in greater efforts to promote sexual well-being and building competence in fostering the trifecta of sexual health, sexual rights, and sexual pleasure.

Searching for Mental Health Services: Search Strings and Information Acquisition.

Based on decision sciences and information processing theories, how information is acquired is the foundation of decisions and choices subsequently made. Adapting the Active Information Search methodology, the aim for this study is to examine what information potential mental health clients look for in a service provider through their use of search strings. College students (N = 519) from a large public university from the southwest USA (data collection from August to December 2018) were asked in an online survey to imagine themselves needing mental health services and list down the search string they would use in a search engine (e.g., Google). Content analysis indicated seven search string categories: location of nearby services, symptoms, types of services/specialty, asking for advice, questions about resources, questions about whether they have a problem, and looking for the "best." Further, multivariate logistic analysis indicated that gender, psychological distress, perceived normativeness of utilizing mental health services, and type of medical insurance were associated with the type of search string the participant used in searching for mental health services. Understanding how individuals search for mental health services can help guide mental health practitioners in what information should be included in their websites. Further findings and implications are discussed.

Early Trauma and Later Sexual Victimization in College Women: A Multiple Mediation Examination of Alexithymia, Impulsivity, and Alcohol Use.

Childhood abuse and sexual violence against women are prevalent in the United States. However, researchers have not fully explored the intersection among important predisposing factors that predict recent sexual violence experienced by women who are also survivors of childhood abuse. The purpose of this study was to examine the relationships among early childhood trauma, alexithymia, impulsivity, alcohol use severity, and sexual victimization in later life among female college students from the United States (n = 1,178). Participants were part of a larger cross-cultural study, conducted between 2012 to 2014, which examined sexual aggression and victimization in the context of alcohol use. The current study aimed to examine if: (a) early trauma, impulsivity, alexithymia, and alcohol use severity impact sexual victimization in later life, and (b) if impulsivity, alexithymia, and alcohol use severity mediate the relationship between early trauma and victimization in later life. It was hypothesized that impulsivity, alexithymia, and alcohol use severity would significantly mediate the relationship between early trauma and sexual victimization in later life. Using a multiple mediation path analysis, results indicated that early childhood trauma was significantly linked with impulsivity, alcohol use severity, and sexual victimization in later life. A partial mediation through impulsivity and alcohol use severity was observed. Alexithymia did not produce mediation effects. These findings align with previous research examining how early childhood trauma influences the occurrence of sexual victimization in later life and provides further recommendations for helping professionals as they attempt to stifle the sexual victimization rates among female college students.

A Cross-Cultural Comparison of the Role of Sexual Objectification in the Relationship Between Alcohol Use and Sexual Assault Perpetration.

In this study, we examined how sexual objectification can help explicate the relationship between alcohol use and sexual assault perpetration. Specifically, we examined a mediation and a moderation model. Moreover, given that gender roles and sexual norms vary across cultures, we also examined the structural invariance of the models between a U.S. male (n = 404) and Philippines male (n = 100) college sample. Path analyses were used to examine the mediation and the moderation model, and multiple groups analysis was utilized to examine model differences between samples. Sexual objectification fully mediated the relationship between alcohol use severity and sexual aggression. Furthermore, the mediation model was invariant between the U.S. sample and Philippines sample. A significant alcohol use severity by sexual objectification interaction effect was found for both samples. Simple slopes analysis indicated that alcohol use severity was not associated with sexual aggression among those with high sexual objectification scores. Among men with low sexual objectification scores, alcohol use severity was associated with higher likelihood toward sexual assault. For the Filipino sample, the impact of alcohol consumption on sexual aggression is more pronounced compared with the U.S. sample. Sexual objectification is a key variable in understanding the alcohol use-sexual aggression relationship. Country differences in alcohol use, cultural meanings of Filipino masculinity, and sexual norms and behaviors accounts for noninvariance in the moderation model. Implications for sexual assault reduction programs were also discussed.

Alexithymia, Prior Trauma, Alcohol Use, and Sexual Aggression Perpetration: A Cross-Cultural Comparison of a Moderated Mediation Model.

In this study, we examined the relationships between prior trauma, alexithymia, and sexual aggression perpetration among 610 U.S. college students and 107 college students from the Philippines utilizing a cross-sectional retrospective design. We tested a moderated mediation model with alexithymia as the mediator between prior trauma and sexual aggression perpetration, and alcohol use as a moderator of the alexithymia-sexual aggression link. Moreover, given that cultural norms may influence these relationships, we also examined the structural invariance of the proposed moderated mediation model. Path analyses and multiple group analysis were used to examine the moderated mediation model, and examine model differences between samples. We did not find evidence for alexithymia as a mediator, but there was a significant interaction between alcohol use severity and alexithymia on sexual aggression perpetration across both samples. Alexithymia is a key variable in understanding the alcohol use-sexual aggression perpetration relationship. Clinical implications and recommendations for future research are also discussed.

Psychosocial treatment for incarcerated methamphetamine users: the Philippines experience.

PURPOSE: The purpose of this study is to evaluate a psychosocial treatment program for prisoners incarcerated because of methamphetamine use. It compared the outcomes of prisoners who received the program while incarcerated, those who were released and received the treatment as part of community-based drug recovery program and a waitlist-control group (WC) with no treatment. DESIGN/METHODOLOGY/APPROACH: A quasi-experimental design was use with pre- and post-test surveys administered to three groups: a WC group, a pre-release treatment-while-incarcerated (TWI) group, and a post-release outpatient treatment group (OP). Surveys measured recovery skills, life skills and substance use disorder (SUD) symptoms were administered before and after the intervention. FINDINGS: Results revealed that at baseline OP and TWI had significant higher recovery skills compared to WC group. However, in terms of life skills, there was no significant difference observed among the WC, OP and TWI group at baseline. TWI had a significantly lower number of SUD symptoms compared to the WC group at baseline. As hypothesized, findings revealed significant changes in recovery and life skills among the OP and TWI group compared to the WC group. No significant change in SUD scores were observed for all groups. RESEARCH LIMITATIONS/IMPLICATIONS: A major limitation of the study was the use of a quasi-experimental design because legal issues did not allow a randomized control trial. Future research using randomized controlled trial designs would provide more robust conclusions on the impact of the intervention. The study design was also limited to pre- and post-evaluation. Further studies are encouraged to look at longitudinal outcomes of appears on SUD symptoms and possibility of relapse. PRACTICAL IMPLICATIONS: Given that there were no significant differences in outcomes between OP and TWI groups, results suggest that the program may serve either as a pre- or post-release program for incarcerated drug users. However, results also suggest that completion is higher when the program is used as a pre-release program. Delivering the program prior to release also reduces challenges related to attrition including conflict in schedules and the lack of resources for transportation. SOCIAL IMPLICATIONS: The study suggests the value of psychosocial treatment as opposed to punitive approaches in dealing with drug use. In particular, delivering interventions prior to release can prepare participants for problems they may encounter during reintegration and prevent recidivism. In a country where drug-related killings are on the rise, the study presents an alternate and restorative justice approach. ORIGINALITY/VALUE: The study addresses a dearth in the literature on psychosocial intervention for methamphetamine users. It also fills a vacuum in studies from developing countries such as the Philippines.

Toronto Alexithymia Scale-20: Examining 18 Competing Factor Structure Solutions in a U.S. Sample and a Philippines Sample.

The Toronto Alexithymia Scale-20 is arguably the most utilized measure of alexithymia. Although a three-factor solution has been found by numerous studies, these findings are not universal. This article examined and compared 18 competing factor structures for the Toronto Alexithymia Scale-20, which included between one and four correlated latent factor structures, common methods models that accounts for negatively worded items, and bifactor models. Although the two-factor bifactor model with a common methods factor had the better model fit compared with the other 17 models examined, it still did not achieve the requisites of a good model fit across all model fit indices. Issues stemmed primarily from the externally oriented thinking factor and the negatively worded items. Post hoc analyses indicated that a two-factor bifactor model with the negatively worded items dropped achieved the requisites of a good model fit and can be treated as a unidimensional measure despite the presence of multidimensionality. Multiple-group analysis indicated that the factor loadings were invariant across U.S. and Philippines samples. After controlling for noninvariance at the item intercept level, the Philippines sample had a higher alexithymia general score compared with the U.S. sample.

Psychometric properties of the perceived stigma towards substance users scale: factor structure, internal consistency, and associations with help-seeking variables.

Background: Stigma toward substance users is a barrier to seeking treatment.Objective: The aim for this paper was to examine the psychometric properties of the Perceived Stigma Toward Substance Users (PSAS) and its relationship with help-seeking variables.Methods: College students (N = 791; nfemales = 557, 70%) responded to the PSAS and other help-seeking-related measures in an online study.Results: Confirmatory factor analysis supported a unidimensional factor structure and acceptable model fit after modifications (CFI = .961; TLI = .937; RMSEA = .067, 90% C.I. = .050 to .085; SRMR = .035). Results indicated good internal consistency estimates (α = .80; ω = .80). The PSAS was negatively associated with intent to seek treatment for substance issues and willingness to self-disclose negative emotions. The PSAS was also positively correlated with stigma associated with seeking help for mental health issues, attitudes concerning risk associated with help-seeking, self-concealment, anticipated risks associated with seeking treatment. When embedded within a larger path model that predicts intent to seek treatment for substance use issues (CFI = .925; TLI = .895; RMSEA = .061, 90%C.I. = .052 to .069; pclose fit = .019; SRMR = .049), the PSAS had an incremental contribution to predicting the criterion variable even after accounting for frequency of alcohol use-related problems, and stigma and attitudes associated with seeking help for general mental health issues.Conclusion: These findings provide further reliability and validity evidence for PSAS, especially in relation to help-seeking variables. Reducing stigma toward substance users can help increase treatment utilization.

The Desire to Dissociate Scale: factor analysis, cross-cultural findings, and links to substance-induced dissociation.

BACKGROUND: Past research identified that a desire for dissociative experiences, rather than dissociative tendencies, mediate the relationship between early sexual abuse and problem drinking in college students. Desire to dissociate was conceptualized as a mechanism facilitating substance-induced dissociation or the use of substances to achieve dissociative-like experiences and was measured using a modified version of the Dissociative Experiences Scale-II. The validity and cross-cultural generalizability of the modified scale are not yet known. OBJECTIVES: The current study examined the psychometric properties of the modified scale, exploring findings across U.S. and Filipino college samples, and explored how the desire to dissociate construct related to other variables linked to substance-induced dissociation. Methods: Participants were recruited across two U.S. samples and one Filipino sample (N = 2404; 72% female). Instead of asking "how often do you experience" dissociative items, 14-items from the original scale were selected and individuals were asked "how often would you like to experience" items. RESULTS: Results supported the validity of the Desire to Dissociate Scale (DDS) with a bifactor model best fitting the data in U.S. and Filipino samples. The bifactor model identified that the DDS primarily measured a general 'desire to dissociate' factor and two specific factors comprised smaller portions of the variance. DDS scores were positively correlated with trauma-related and alcohol use variables including drinking to cope, variables conceptually consistent with theories of substance-induced dissociation. CONCLUSION: Clinical implications address avoidant coping patterns and differences in specific factor findings between U.S. and Filipino samples.

A comparison between telehealth and face-to-face delivery of a brief alcohol intervention for college students.

BACKGROUND: Problematic alcohol use is a common occurrence among college students. While empirically supported interventions exist, their access is typically limited to those with greater resources. There has been an expansion of services provided via telehealth to increase client access to treatment in the health care field. However, the evidence is mixed regarding the effectiveness of face-to-face versus telehealth interventions and there is a gap in the literature regarding brief alcohol interventions delivered via telehealth. As such, the purpose of this study was to test the effectiveness of a well-validated brief alcohol screening and intervention for college students (BASICS) when conducted face-to-face or through a videoconferencing system. Method: Participants included 51 college students who engaged in heavy episodic drinking (5+ drinks for males and 4+ drinks for females over a two hour period) over the last two weeks. They were randomly assigned to receive the face-to-face or telehealth intervention and completed a variety of questionnaires throughout. Follow up data on the participant's alcohol use and alcohol-related problems was collected at 1-, 2-, and 3-months. Multilevel modeling in SAS was utilized for analyses, which included the modeling of treatment outcome trajectories and the influence of predictors on the trajectory of change for each outcome. Results: Results indicated that the intervention significantly reduced alcohol consumption and related problems regardless of condition. Both conditions saw an increase in treatment satisfaction and therapeutic alliance between the two sessions. Increased therapeutic alliance resulted in greater decreases in alcohol use and related harm across both conditions. Additionally, those with a mental health diagnosis showed greater improvement related to risk reduction for both treatment modalities. Conclusion: In sum, the results of this study suggest that telehealth services should be further implemented and the BASICS intervention can be effectively delivered via telehealth for college students.

Examining the role of a brief online alcohol use risk feedback on accessing information about available treatment resources for alcohol issues.

Research suggests college-aged young adults are hesitant to seek treatment for alcohol use disorder and highlights barriers contributing to a gap in treatment utilization. One barrier to treatment utilization is the lack of information about available treatment resources. Motivated by the literature on web-based screening and brief interventions (eSBIs), the current study examined whether providing a brief online feedback of one's alcohol use risk severity will make college students more likely to access information about available treatment options for alcohol-related issues. College students (N = 724) who responded to the Alcohol Use Disorder Identification Test (Babor, Higgins-Biddle, Saunders, & Monteiro, 2001) were randomly assigned to receive a brief online feedback on their alcohol use risk or to a no-feedback condition. Overall, only 20% of all participants opted to view available treatment services for alcohol issues. Participants in the feedback group (15%) were significantly less likely to view information for available services compared to the no-feedback group (24%). A significant feedback condition x stigma interaction effect was found, such that those with average and high stigma towards substance use scores were less likely to view treatment information when provided feedback. Without a thorough discussion of individual risks and without the safeguards against psychological reactance present in eSBIs, providing college students with brief online feedback about their alcohol use risk severity made them less likely to access information concerning available on-campus mental health resources for alcohol issues. On the other hand, improving help-seeking attitudes could help increase treatment utilization.

Long-Term Effectiveness of a Brief Restorative Justice Intervention.

This research investigated the effectiveness of a brief Restorative Justice Intervention. Probationers who attended a Restorative Justice Intervention ( n = 383) were compared with probationers receiving treatment as usual ( n = 130) over a 2- to 6-year follow-up period. The proportion of individuals who recidivated in the control condition ( n = 89, 68.46%) were higher compared with those who recidivated in the intervention condition ( n = 127, 33.16%; z = 7.04, p < .001). In addition, among those who recidivated, those in the intervention condition did so less frequently. Qualitative analyses from a postintervention course evaluation given only to the intervention condition showed that 50% of probationers acknowledged an empathic understanding associated with participation. This brief intervention has a positive multilevel impact on restorative justice. Implications of these effects are discussed.

Measuring individual differences in responses to date-rape vignettes using latent variable models.

Vignette methodology can be a flexible and powerful way to examine individual differences in response to dangerous real-life scenarios. However, most studies underutilize the usefulness of such methodology by analyzing only one outcome, which limits the ability to track event-related changes (e.g., vacillation in risk perception). The current study was designed to illustrate the dynamic influence of risk perception on exit point from a date-rape vignette. Our primary goal was to provide an illustrative example of how to use latent variable models for vignette methodology, including latent growth curve modeling with piecewise slopes, as well as latent variable measurement models. Through the combination of a step-by-step exposition in this text and corresponding model syntax available electronically, we detail an alternative statistical "blueprint" to enhance future violence research efforts using vignette methodology.

Alcohol Expectancies, Posttraumatic Stress Disorder, and Alcohol Use in College Students With a History of Childhood Trauma.

OBJECTIVE: Prior research has emphasized that the key mediator in the posttraumatic stress disorder (PTSD) symptom-alcohol use relationship is the expectancy of alcohol's tension-reducing properties. This study extends the literature by examining various alcohol outcome expectancies. METHODS: Cross-sectional data were obtained from 198 college students who reported experiencing at least one traumatic event in childhood. Participants answered surveys measuring PTSD symptoms, alcohol outcome expectancies, and three measures of alcohol consumption and related problems. RESULTS: Participants included 131 males (mean age = 19.65 years, SD = 1.06, range = 18 to 24) and 67 females (mean age = 19.43 years, SD = 0.82, range = 18 to 23), who were predominantly European-American (82%). For males and females, results of the multivariate analyses suggested that self-perception expectancies mediated the effects of PTSD symptoms on alcohol use severity, whereas sociability expectancies mediated the effects of PTSD symptoms on monthly alcohol use. For women, risk and aggression and sexuality expectancies mediated the relationship between PTSD symptoms and alcohol use severity, while risk and aggression expectancies mediated the relationship between PTSD symptoms and alcohol use consequences. For men, sociability expectancies mediated the effects of PTSD symptoms on alcohol use severity. Across genders, tension-reduction expectancies did not mediate the relationship between PTSD symptom and the three alcohol measures. CONCLUSIONS: This study was unable to find support for the self-medication hypothesis via the tension-reduction outcome expectancy pathway. However, other significant findings can be interpreted in light of the self-medication hypothesis. For example, alcohol may aid in coping with social impairments related to PTSD symptoms, particularly in a college sample. This study also highlighted gender differences in the association between PTSD symptoms and alcohol consumption and related problems.

Proposed pathways to problematic drinking via post-traumatic stress disorder symptoms, emotion dysregulation, and dissociative tendencies following child/adolescent sexual abuse.

The relationship between early sexual abuse and college problem drinking was examined using an integration of the self-medication and vulnerability-stress models. Baseline survey data from parti-cipants (N = 213; 135 men and 78 college women) completing a mandated, brief alcohol intervention were utilized. Representative of the self-medication model, post-traumatic stress disorder symptoms mediated the early sexual abuse/problem drinking relationship. Two psychological vulnerability factors-emotion dysregulation and dissociative tendencies-were incorporated into self-medication findings via more advanced mediational models. Results highlighted that problem drinking increased as dissociative tendencies increased, and relations between the vulnerability factors and post-traumatic stress disorder symptoms were in an unexpected direction.

Factor structure and invariance test of the alcohol use disorder identification test (AUDIT): Comparison and further validation in a U.S. and Philippines college student sample.

The Alcohol Use Disorder Identification Test's factor structure varies depending on population and culture. Because of this inconsistency, this article examined the factor structure of the test and conducted a factorial invariance test between a U.S. and a Philippines college sample. Confirmatory factor analyses indicated that a three-factor solution outperforms the one- and two-factor solution in both samples. Factorial invariance analyses further supports the confirmatory findings by showing that factor loadings were generally invariant across groups; however, item intercepts show non-invariance. Country differences between factors show that Filipino consumption factor mean scores were significantly lower than their U.S. counterparts.

Posttraumatic stress disorder symptoms, emotion dysregulation, and aggressive behavior among incarcerated methamphetamine users.

OBJECTIVE: Methamphetamine use remains a prevalent problem in the United States and is linked to numerous deleterious outcomes, including aggressive behavior, criminal activity, and incarceration. Given these associations, a greater understanding of factors that contribute to aggression among users of methamphetamine is needed, particularly within criminal justice settings, where users of this drug are overrepresented. METHODS: The present study examined the relationships between posttraumatic stress disorder (PTSD) symptoms and emotion dysregulation and in-prison physical aggression among incarcerated males who identified as methamphetamine users (N = 60). RESULTS: Participants' average age was 34.4 years (SD = 7.9), and they were predominantly European American (n = 48, 80%), had spent an average of 6.53 years incarcerated (SD = 4.64), and perpetrated about 1.54 acts of aggression (SD = 6.74) during the past three months. Bivariate correlations found that greater PTSD symptoms (p < .001), greater impulse control difficulties (p < .001), and limited access to emotion regulation strategies (p < .05) were associated with aggression perpetrated in prison. However, results from multiple regression analyses indicated that only PTSD symptoms (p <.001) and nonacceptance of emotional responses (p < .03) were predictive of aggression. Regression analyses also suggested that impulse control difficulties (p < .001), limited access to emotion regulation strategies (p < .04), and nonacceptance of emotional responses (p < .001) interacted with PTSD symptoms to predict increased aggressive behavior. The first interaction ran counter to study hypotheses: At greater levels of PTSD symptoms, those with greater acceptance of emotional responses reported greater aggression perpetration than those with lesser acceptance of emotional responses. The other two interactions were in line with hypotheses, showing that at greater levels of PTSD symptoms, those with greater impulse control difficulties (or lesser access to emotion regulation strategies) reported more aggressive behaviors. CONCLUSIONS: Consistent with theories of aggression, study findings suggest that PTSD symptoms bolster the risk of aggression via various forms emotion dysregulation. Results shed light on potential mechanisms that promote in-prison aggression and violent recidivism among this population.
