Mental health of unaccompanied refugee minors in Greece living "in limbo".

The closure of the Balkan migration route in 2016, had implications for unaccompanied refugee minors (URMs), given that the vast majority, who perceived Greece as "stopover" for their desired final destination, were forced to remain in the country for an indeterminate period of time. This created for URMs a challenging situation of living "in limbo" uncertain about their future awaiting for a long time the outcome of their asylum application. This cross-sectional study aimed to explore the mental health of URMs, who arrived in Greece in 2016. The sample comprised 90 URMs (76 boys), aged 13-17 years, consisting of 46 Syrians and 44 originating from other countries. Participants completed socio-demographic information and a range of clinical measures, including Children's Revised Impact of Events Scale (CRIES), Depression Self-Rating Scale (DSRS), Children's Post-Traumatic Cognitions Inventory (cPTCI), a measure of trauma exposure and perceived social support. Syrian URMs were significantly more likely than URMs originating from other countries to score within the probable clinical depression range (71.7% versus 47.7% respectively, p=0.020), to display probable posttraumatic stress disorder (PTSD), i.e., score within clinically significant range of posttraumatic stress symptoms and negative post-trauma cognitions (87% versus 65.9%, p=0.018), and meet the comorbidity PTSD/depression criterion (65.2% versus 40.9%, p=0.021). Multiple linear stepwise regression analyses showed that legal status (seeking asylum in Europe through family reunification procedure) significantly predicted higher levels of depressive symptoms (β=0.29, p=0.004), posttraumatic stress symptoms (β=0.21, p=0.034) and negative cognitions (β=0.33, p=0.001). The total number of stressful/traumatic experiences and male gender were found to be significantly related only with posttraumatic symptoms severity score (β=0.29, p=0.003), whereas lower levels of perceived social support were associated with increased levels of depressive symptoms (β=0.24, p=0.018) and negative cognitions and appraisals of the world and the self (β=0.26, p=0.008). These findings highlight the burden of living "in limbo" situation and add weight to the argument for amending restrictive EU asylum policies and accelerating the family reunification procedure under Dublin-III Regulation, as well as the pressing need for improved URMs access to mental health services and psychosocial support.

A Pilot Trial of Universal School-Based Mental Health Screening in El Salvador: Traumatic Stress in an Underresourced School Environment.

Salvadoran youth have an elevated risk of trauma exposure and related mental health problems. However, investigations of childhood trauma exposure and mental health sequelae in El Salvador are limited. The present study aimed to (a) explore the prevalence of exposure to potentially traumatic events and symptoms of posttraumatic stress, anxiety, and depression and (b) evaluate the associations between specific trauma types and emotional functioning among Salvadoran youth. A total of 1,296 youth aged 8-21 years from seven public schools completed self-report measures of trauma exposure, posttraumatic stress symptoms (PTSS), anxiety, and depression. Participants reported high levels of trauma exposure, endorsing an average of 3.62 (SD = 2.32) trauma types. In total, 34.5% of participants reported clinically elevated PTSS; fewer youths reported elevated depressive (8.7%) and anxiety symptoms (8.6%). Although boys reported exposure to more trauma types than girls, d = 0.22, girls were more likely to endorse elevated PTSS, V = .11; anxiety, V = .06; and depression, V = .10. Adolescents reported exposure to more trauma types than younger children, d = 0.23, and were more likely to endorse elevated PTSS, V = .07; anxiety, V = .13; and depression, V = .16. Undergoing a frightening medical procedure, OR = 2.30; female sex, OR = 1.92; witnessing domestic violence, OR = 1.70; and experiencing war between gangs, OR = 1.61, were strong predictors of elevated PTSS. This broad, school-based screening was a critical step toward better understanding the rate of trauma exposure and trauma-related symptoms among Salvadoran youth.

Patterns of distress associated with exposure to potentially morally injurious events among Canadian Armed Forces service members and Veterans: A multi-method analysis.

This study describes patterns of distress associated with exposure to potentially morally injurious experiences (PMIEs) in a Canadian military sample. Thematic analysis was performed on interviews from PMIE-exposed military members and Veterans. Participants also completed structured diagnostic interviews, and measures of trauma exposure and psychopathology. Multiple regression examined associations among these variables. Information on pharmacological treatment and past diagnoses are reported. Eight qualitative themes were identified: changes in moral attitudes, increased sensitivity and reactivity to moral situations, loss of trust, disruptions in identity, disruptions in spirituality, disruptions in interpersonal relatedness, rumination, and internalizing and externalizing emotions and behaviors. Self-report data revealed that degree of PMIE exposure was meaningfully associated with posttraumatic stress disorder. Qualitative but not quantitative findings supported existing models of moral injury (MI). Additional research is needed to examine the impact of PMIE type on mental health, and to test basic assumptions of MI theory.

The association between latent trauma and brain structure in children

The developing brain is marked by high plasticity, which can lead to vulnerability to early life stressors. Previous studies indicate that childhood maltreatment is associated with structural aberrations across a number of brain regions. However, prior work is limited by small sample sizes, heterogeneous age groups, the examination of one structure in isolation, the confounding of different types of early life stressors, and not accounting for socioeconomic status. These limitations may contribute to high variability across studies. The present study aimed to investigate how trauma is specifically associated with cortical thickness and gray matter volume (GMV) differences by leveraging a large sample of children (N = 9270) from the Adolescent Brain Cognitive DevelopmentSM Study (ABCD Study®). A latent measure of trauma exposure was derived from DSM-5 traumatic events, and we related this measure of trauma to the brain using structural equation modeling. Trauma exposure was associated with thinner cortices in the bilateral superior frontal gyri and right caudal middle frontal gyrus (pfdr-values < .001) as well as thicker cortices in the left isthmus cingulate and posterior cingulate (pfdr-values ≤ .027), after controlling age, sex, and race/ethnicity. Furthermore, trauma exposure was associated with smaller GMV in the right amygdala and right putamen (pfdr-values ≤ .048). Sensitivity analyses that controlled for income and parental education were largely consistent with the main findings for cortical thickness. These results suggest that trauma may be an important risk factor for structural aberrations, specifically for cortical thickness differences in frontal and cingulate regions in children.

Associations Among Trauma Exposure, Posttraumatic Dissociation, Reckless/Self-Destructive Behavior, and Adolescent Offending

ABSTRACT Previous research has established that trauma exposure and subsequent posttraumatic stress symptoms confer risk for adolescent offending and involvement in the juvenile justice system. However, recent research and theory have called attention to the contributions of specific posttraumatic reactions, including posttraumatic dissociation (PD) and reckless or self-destructive behavior (RSDB), to offending behavior among adolescents. Therefore, this study investigated direct and indirect associations among trauma exposure, PD, RSDB, and offending in a sample of justice-involved adolescents. Participants were 301 adolescents (Mage = 16.03, SD = 1.24; 21% girls) recruited from a detention center in the Mountain West. The sample was racially and ethnic diverse, with 63% identifying as a racial or ethnic minority. Youth completed self-report measures of trauma exposure, PD, RSDB, and offending. As hypothesized, results of multiple mediation analysis demonstrated a significant indirect effect linking trauma exposure and offending through PD and RSDB. Results testing an alternative multiple mediation model were non-significant. These findings suggest that PD and RSDB may serve as key links accounting for the association between trauma exposure and offending behavior and reinforce the value of incorporating trauma-informed practices within juvenile justice systems.

Moral injury in civilians: associations with trauma exposure, PTSD, and suicide behavior

ABSTRACT Background: Moral injury (MI) describes emotional, spiritual, and social suffering that can arise following psychological trauma. Prior research in military populations indicates the relevance of MI to adverse psychological outcomes, such as post-traumatic stress disorder (PTSD) and suicidal behaviours, and shows evidence for MI as a unique construct. Minimal studies of MI have been implemented in civilians, usually restricted to small samples with a specific set of traumatic experiences, despite the conceptual relevance of MI to non-military trauma reactions more broadly (e.g. feelings of betrayal towards a perpetrator of sexual abuse). Objective: To address this problem, we assessed MI in trauma-exposed civilians to examine ways in which this construct was related to and distinct from trauma and traumatic stress-related problems, including PTSD and depression. Method: We adapted an existing MI scale, Moral Injury Events Scale (MIES) and administered this measure to 81 men and women along with measures of trauma exposure, PTSD and depression, and also asked participants about past suicide attempts. Results: We observed that both greater exposure and distress related to potentially morally injurious events were associated with higher trauma exposure, particularly childhood maltreatment, as well as post-traumatic and depressive psychopathology. However, even after accounting for current PTSD and depression symptoms, MI exposure (F = 6.05, p = .017) was significantly higher among participants who had previously attempted suicide. Conclusions: These pilot data reveal the ways in which MI is associated with trauma exposure, PTSD and depression and highlight the salience of MI in civilians. Similarly, these data demonstrate the unique relevance of MI to suicide behaviours, independent of post-traumatic psychopathology, indicating that this construct may be an understudied contributor to suicide risk in civilians.

Posttraumatic stress and co-occurrence of mental health problems in Sri Lankan adolescents.

A significant minority (5 %) of adolescents develop posttraumatic stress disorder (PTSD) after trauma exposure. These adolescents are likely to experience many other mental health problems and have related impaired functioning. This study examined the co-occurrence of Emotional and Behavioral Problems (EBP) with PTSD symptoms and investigated the effect of PTSD symptoms on EBP-related impaired functioning. The initial sample (T1) comprised 729 Sri Lankan adolescents, age 12-16 years, living in an area impacted by the 2004 tsunami. In 2008, participants (T1) completed measures of trauma exposure, PTSD symptoms, EBP and related functional impairment. Sixteen months later a subsample of 90 adolescents (T2) underwent diagnostic interview for PTSD and co-occurrence of mental health morbidity. In the 58.2 % of the T1 sample reporting any trauma exposure, 23.7 % met criteria for full or partial PTSD. Among all participants, 13.4 % had borderline to abnormal levels of EBP. EBP was significantly higher among PTSD-positive participants compared to PTSD-negative and non-traumatized subgroups (p < 0.001). In the T2 sample, all four cases with diagnosed PTSD had coexisting psychological problems. Further, PTSD symptoms exacerbated the impact of EBP on functional impairment. Findings support the conclusion that researchers and practitioners should be alert to EBP among trauma-exposed adolescents, because such general psychological problems are common and, in combination with PTSD symptoms, are associated with even greater impairment. Moreover, identifying the presence of these trauma associated problems is of crucial clinical importance.

Patterns and predictors of PTSD in treatment-seeking African refugees and asylum seekers: A latent class analysis.

Despite the empirical and clinical relevance of understanding posttraumatic stress disorder (PTSD) heterogeneity in refugees and asylum-seekers, very few studies have examined the manner in which PTSD symptoms manifest in such populations. This study sought to investigate patterns and predictors of DSM-5 PTSD in a treatment-seeking sample of African refugees. Participants were 122 African refugees and asylum-seekers living in Italy who completed measures of trauma exposure and PTSD symptoms. Latent class analysis (LCA) was used to identify PTSD symptom profiles, and predictors of class membership were identified via multinomial logistic regression. Among participants, 79.5% had a probable diagnosis of PTSD. Three PTSD classes were identified by LCA: Pervasive (32.0%) with high probabilities of all symptoms, high-Threat (45.9%) with higher probabilities of intrusions and avoidance symptoms, moderate-Avoidance (22.1%) with high probability of thoughts/feelings avoidance. None of the examined variables (legal status, gender, age, education, months spent in Italy, number of traumatic events, employment) significantly predicted class membership with the relevant exception of reception conditions. Specifically, living in large reception centres (over 1,000 people) significantly predicted Pervasive PTSD class membership compared to high/Threat PTSD class and to moderate/Avoidance class. This study provides evidence for distinct patterns of PTSD symptomatology in refugees and asylum seekers. We identified three classes which present both qualitative and quantitative differences in symptoms: Pervasive class, high-Threat class and a new moderate class, characterised by avoidance symptoms. Reception conditions contributed to the emergence of the Pervasive PTSD profile characterised by the symptoms highest severity. These findings highlight that stressors in the post-migration environment, as inadequate reception conditions in large facilities, may have detrimental effect on refugees' mental health. We emphasise the importance for host countries to implement reception models that provide effective protection and integration to this vulnerable population.

The Association Between Posttraumatic Stress Symptoms and Anxiety Sensitivity in a College Sample.

One-half of all U.S. adults will experience at least one traumatic event, and of those, approximately 11% develop posttraumatic stress disorder (PTSD) symptoms. Despite efficacious treatments for PTSD, one-third of people diagnosed still express symptoms after treatment.Thus, it is important to identify underlying factors that may be associated with PTSD symptom clusters to improve treatment efficacy. One potential factor is anxiety sensitivity (AS), or "the fear of fear," and includes three different subfactors: physical, cognitive, and social concerns, yet few studies have examined this association using the Anxiety Sensitivity Index-3. Participants included 65 undergraduate students from a Southeastern University who were elevated on anxiety sensitivity cognitive concerns and experienced at least one traumatic event. Participants completed measures of trauma exposure, anxiety sensitivity, posttraumatic stress symptoms, and suicidal ideation. Results revealed that AS physical symptoms had the most robust association with potential PTSD symptoms and individual PTSD symptom clusters with the exception of the avoidance and numbing cluster. These findings may help clarify the nature of the relationship between PTSD symptoms and AS using the most updated measure of AS (ASI-3).

Cumulative Trauma Exposure and Chronic Homelessness Among Veterans: The Roles of Responses to Intrusions and Emotion Regulation.

Veterans with mental health problems and a history of interpersonal and military trauma exposure are at increased risk for chronic homelessness. Although studies have examined posttraumatic stress disorder (PTSD) as a predictor of homelessness, there is limited understanding of specific mechanisms related to cumulative trauma exposure. We sought to elucidate how cumulative interpersonal and military trauma exposure may be linked to homelessness chronicity by examining the role of factors that influence trauma recovery and functional impairment. Specifically, we examined the indirect association of cumulative trauma exposure with homelessness chronicity through distress and responses to trauma-related intrusions and emotion regulation problems in a sample of 239 veterans in community-based homeless programs. Participants completed measures of trauma exposure, responses to intrusions, intrusion distress, difficulties with emotion regulation, and duration and episodes of homelessness. Structural equation modeling was used to test a serial indirect effect model in which cumulative trauma exposure was indirectly associated with homelessness chronicity through distress from and responses to intrusions as well as emotion regulation problems. The results supported the hypothesized sequential indirect effect for episodes of homelessness, indirect effect odds ratio (IE ORs) = 1.12-1.13, but not for current episode duration, IE OR = 1.05. Overall, the present findings elucidate specific trauma-related factors that may be particularly relevant to episodic patterns of homelessness and interfere with efforts to remain housed. These findings represent an important step toward shaping policy and program development to better meet mental health care needs and improve housing outcomes among homeless veterans.

Application of PTSD alcohol expectancy symptom clusters to the four-dimensional model of PTSD: Support from moderations of the association between symptoms of posttraumatic stress and alcohol use.

Alcohol expectancy theory, which examines beliefs about the effects of alcohol on the consumer, is especially relevant for understanding the role of alcohol use in posttraumatic stress disorder (PTSD). Previous research on the relationship between alcohol expectancies and PTSD suggests that greater endorsement of positive alcohol expectancies is positively associated with alcohol use, problem drinking, and increased PTSD symptomatology. The purpose of the current study was to investigate relationships among positive and negative PTSD alcohol expectancies, PTSD symptom clusters, and alcohol use in a sample of undergraduates. Additionally, a 4-factor structure of PTSD alcohol expectancies, based on the supported 4-domain model of PTSD, was examined. Participants included 336 undergraduates at a large Midwestern university who completed measures of trauma exposure, PTSD symptomatology, PTSD alcohol expectancies, and alcohol use. Moderation analysis found positive alcohol expectancies influenced the relationship between posttraumatic stress (PTS) and alcohol use. Additionally, each of 4 proposed symptom clusters of PTSD alcohol expectancies moderated the association between corresponding PTSD symptom clusters and alcohol use. No support for the utility of negative alcohol expectancies was found. The current study provides support for a PTSD symptom domain-specific approach for measuring alcohol expectancies. Though limited in generalizability, this research also provides evidence for positive PTSD alcohol expectancies as an important moderator in the relationship between symptoms of PTS and alcohol, suggesting that perceptions of alcohol's effect on PTSD symptoms confer risk for problematic drinking.

Genetic liability to schizophrenia is associated with exposure to traumatic events in childhood.

There is a wealth of literature on the observed association between childhood trauma and psychotic illness. However, the relationship between childhood trauma and psychosis is complex and could be explained, in part, by gene-environment correlation. The association between schizophrenia polygenic scores (PGS) and experiencing childhood trauma was investigated using data from the Avon Longitudinal Study of Parents and Children (ALSPAC) and the Norwegian Mother, Father and Child Cohort Study (MoBa). Schizophrenia PGS were derived in each cohort for children, mothers, and fathers where genetic data were available. Measures of trauma exposure were derived based on data collected throughout childhood and adolescence (0-17 years; ALSPAC) and at age 8 years (MoBa). Within ALSPAC, we found a positive association between schizophrenia PGS and exposure to trauma across childhood and adolescence; effect sizes were consistent for both child or maternal PGS. We found evidence of an association between the schizophrenia PGS and the majority of trauma subtypes investigated, with the exception of bullying. These results were comparable with those of MoBa. Within ALSPAC, genetic liability to a range of additional psychiatric traits was also associated with a greater trauma exposure. Results from two international birth cohorts indicate that genetic liability for a range of psychiatric traits is associated with experiencing childhood trauma. Genome-wide association study of psychiatric phenotypes may also reflect risk factors for these phenotypes. Our findings also suggest that youth at higher genetic risk might require greater resources/support to ensure they grow-up in a healthy environment.

Emotion regulation as a transdiagnostic factor in Afghan refugees.

In response to the high rates of comorbidity as well as the severe social impairment among refugees, the examination of transdiagnostic factors such as emotion regulation appears particularly promising in this group. This study investigates the contribution of difficulties in emotion regulation to the self-reported symptom levels of posttraumatic stress disorder (PTSD), depression, and anxiety/insomnia, which are highly prevalent symptoms among refugees. In addition, the link between emotion regulation and social impairment is examined. Participants were 74 male Afghan refugees exposed to trauma. They completed measures of trauma exposure, difficulties in emotion regulation (Difficulties in Emotion Regulation Scale), PTSD (PTSD Checklist for DSM-5), depression, anxiety/insomnia, and social impairment (General Health Questionnaire-28). Higher symptom severities of PTSD, depression, and anxiety/insomnia were related to the Difficulties in Emotion Regulation Scale subscales nonacceptance, goals, impulse, strategies, and clarity, but none of our outcomes was related to lack of emotional awareness. Difficulties in emotion regulation accounted for significant variance in PTSD, depression, and anxiety/insomnia beyond demographics and trauma exposure. When predicting social impairment, difficulties in emotion regulation accounted for significant variance beyond PTSD and anxiety/insomnia but not beyond depression. The findings indicate that emotion regulation may be a transdiagnostic key factor contributing to symptoms of different mental disorders as well as social impairment in trauma-exposed refugees. It highlights the need and potential directions for transdiagnostic interventions that target these difficulties. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Associations Among Trauma Exposure, Callous-Unemotionality, Race or Ethnicity, and Gang Involvement in Justice-Involved Youth

The current study examined the association between trauma exposure and gang involvement and whether these interrelations were explained by callous-unemotionality (CU). In addition, the current study examined whether the associations among these variables differed based on race or ethnicity. A sample of 829 justice-involved youth (74% boys, 45% participants of color) recruited from a detention center completed self-report measures of trauma exposure, CU, and gang involvement. A moderated mediation analysis indicated that CU helped explain the association between trauma exposure and gang involvement for non-Hispanic White participants only. In contrast, the direct association between trauma exposure and gang involvement was significant across racial or ethnic groups. These findings highlight the importance of a trauma-informed perspective on intervening and preventing gang involvement among youth.

Investigating the Association Between Posttraumatic Risky Behavior and Offending in Adolescents Involved in the Juvenile Justice System.

Risky behavior is common among traumatized youth and is associated with juvenile offending. This study examined predictors of posttraumatic risky behavior, the unique contribution of posttraumatic risky behavior in predicting offending, and tested whether a distinct class of youth was characterized by high levels of posttraumatic risky behavior. Participants were 400 adolescents (25% girls) between the ages of 12 and 19 years old (M = 15.97, SD = 1.25) who were involved in the Utah juvenile justice system. Approximately 54% of the sample identified as an ethnic minority. Youth completed self-report measures of trauma exposure, posttraumatic risky behavior, posttraumatic stress symptom severity, and offending. Formal legal records of offending were also collected. The results indicated that female sex was significantly related to posttraumatic risky behavior, though age was not significantly associated with posttraumatic risky behavior. Age and ethnicity were associated with both self-reported and formal offending, and male sex was associated with formal offending. Posttraumatic risky behavior was not related to formal offending, but was related to self-reported offending in some of the tested models. Latent class analysis identified 92 youth characterized by high levels of posttraumatic risky behavior; these youth also evidenced the highest rates of trauma exposure, posttraumatic stress symptom severity, and self-reported offending. There were no ethnic, age, or sex differences between youth in the high and low posttraumatic risky behavior groups. These results add to the extant literature documenting the associations among exposure to trauma, posttraumatic stress, and juvenile offending.

A latent profile analysis of coping responses to individuals’ most traumatic event: associations with adaptive and maladaptive mental health outcomes

ABSTRACTBackground & Objectives: This study explores how empirically-derived coping response patterns influence mental health.Design: Emerging adults, currently enrolled in college and aged 18–24 (N = 432; Mage = 19.66; SD = 1.65), completed self-report measures of trauma exposure, coping responses to self-selected most traumatic event (MTE), resilience, posttraumatic growth (PTG), depressive symptoms, and posttraumatic stress symptoms (PTSS).Methods: Eight coping subscales were included as indicators in a latent profile analysis. Then, associations between established profiles and mental health outcomes were examined, covarying for demographic and trauma-related variables.Results: Considering fit statistics, class size, profile patterns, and theory, the four-class model was deemed most appropriate: High Overall Coping (HCOPE; n = 146, 34%), Low Overall Coping (LCOPE; n = 92, 22%), High Engagement Coping (HENG; n = 115, 27%), and High Disengagement Coping (HDIS; n = 73, 17%). HENG participants endorsed above-average resilience and PTG, coupled with below-average depressive symptoms and PTSS. Compared to the sample average, HDIS participants endorsed lower resilience and PTG, coupled with higher depressive symptoms and PTSS. LCOPE participants endorsed low levels of all outcomes. HCOPE participants endorsed high levels of all outcomes.Conclusions: Findings suggest that clinicians who promote engagement coping and discourage disengagement coping among trauma-exposed individuals may engender the most desirable constellation of mental health outcomes.

Posttraumatic Stress Symptoms Mediate the Effects of Trauma Exposure on Clinical Indicators of Central Sensitization in Patients With Chronic Pain.

Evidence supports high rates of co-occurrence of posttraumatic stress disorder (PTSD) and chronic pain disorders involving central sensitization (CS). The nature of this relationship, however, remains relatively unexplored. In this study, we aimed to (1) assess how both trauma exposure and current PTSD symptoms are related to clinical manifestations of CS, and (2) test whether PTSD symptoms explain the relationship between trauma exposure and CS. Because experiential avoidance has been shown to impact the relationship between trauma and health outcomes, we (3) explored experiential avoidance as a possible mediator or moderator of the trauma-CS relationship. A sample of 202 adult patients (79% female) with chronic pain completed validated self-report measures of trauma exposure, current PTSD symptoms, experiential avoidance, and 3 manifestations of CS: widespread pain, greater pain severity, and polysomatic symptom reporting. We used path analysis and multivariate regression to assess our study aims. Both trauma exposure and PTSD symptoms were significantly associated with all 3 clinical indicators of CS. PTSD symptoms partially explained the relationship between trauma exposure and widespread pain, pain intensity, and polysomatic symptoms. Experiential avoidance did not mediate or moderate the trauma-CS relationship. Our findings suggest that trauma exposure is linked to elevated clinical markers of CS but a critical factor in this relationship is the mediating effect of current PTSD symptoms.

Trauma Exposure and PTSD Among Women Receiving Treatment for Intimate Partner Violence Perpetration.

Trauma exposure and posttraumatic stress disorder (PTSD) symptoms have been associated with men's perpetration of intimate partner violence (IPV), but relatively little research has examined these associations among women who perpetrate IPV. This exploratory investigation evaluated the associations among trauma, PTSD symptoms, and IPV perpetration for women and a comparison sample of men. During intake at a community-based Abuse Intervention Program (AIP), women (n = 32) and a demographically similar comparison sample of men (n = 64) completed measures of trauma exposure, PTSD symptoms, physical aggression and emotional abuse perpetration, and use of alcohol and other drugs. The vast majority of women (93.5%) reported traumatic event exposure, and close to half (43.8%) screened positive for a probable PTSD diagnosis. Women's level of PTSD symptoms correlated positively with emotional abuse perpetration, with medium-to-large effect sizes. After controlling for substance use, women's PTSD symptoms were significantly and positively correlated with physical assault and emotional abuse perpetration. Women reported significantly higher rates of exposure to IPV victimization and had significantly higher rates of probable PTSD and PTSD symptoms than did men from the same AIP. Gender did not significantly moderate the associations between PTSD symptoms and IPV perpetration. Overall, findings indicate that trauma exposure and PTSD symptoms are important correlates of women's IPV perpetration. Women in treatment for IPV perpetration may benefit from additional assessment and treatment of trauma and trauma-related symptoms.

Deficits in Inhibitory Control May Place Service Members at Risk for Posttraumatic Stress Disorder and Negative Parenting Behavior Following Deployment-Related Trauma.

This study examined the mediating role of posttraumatic stress disorder (PTSD) symptoms in the association between deployment-related trauma exposure and parenting behaviors in reserve-component military service members and whether this association was contingent upon parent inhibitory control (IC). Participants were 181 postdeployed fathers and their children. Fathers completed a neurospychological test of IC and self-report measures of trauma exposure and PTSD symptoms. Measures of parenting behaviors (positive engagement and reactivity coercion) were obtained from direct observation of father-child interaction. Results demonstrated that (a) fathers' PTSD symptoms indirectly mediated the effect of trauma exposure on both measures of parenting (i.e., negative indirect effect for positive engagement, point estimate = -.0045, 95% CI [-.0107, -.0003], and positive indirect effect for reactivity coercion, point estimate = .0061, 95% CI [.0007, .0146]); (b) fathers' IC skills moderated the association between trauma exposure and PTSD, β = .14, p = .043, such that the association was positive and significant for fathers with high and medium IC but nonsignificant for fathers with low IC; and (c) the indirect effect of trauma exposure on both parenting measures through PTSD was dependent upon IC, point estimate = .0341, 95% CI [.0005, .0687]. These findings indicate that fathers with low IC skills tended to have higher rates of PTSD symptoms and related negative parenting behaviors, even for individuals with relatively low degrees of deployment-related trauma exposure. Results highlight the importance of IC as a potential moderating factor in the association between trauma exposure, PTSD, and parenting.

Posttraumatic stress disorder clusters and suicidal ideation

BackgroundPosttraumatic stress disorder (PTSD) is associated with suicidal ideation and behavior. However, less is known about how the PTSD symptom clusters, namely alterations in arousal and reactivity (AAR), negative alterations in cognitions and mood (NACM), avoidance, and intrusion, uniquely relate to suicidal ideation. This study aimed to characterize the associations among suicidal ideation and these symptom clusters. MethodsStudy 1 (n = 346) and Study 2 (n = 194) included community members and treatment-seeking adults at an anxiety specialty clinic, respectively. Participants completed measures of trauma exposure, PTSD symptoms, and suicidal ideation. ResultsIn both studies, suicidal ideation significantly and positively correlated with all PTSD factors. In Study 1, Wald tests of parameter constraints indicated that NACM and AAR had the strongest associations with suicidal ideation, followed by intrusion and avoidance. Results were replicated when restricting the sample to individuals with probable PTSD. In Study 2, suicidal ideation significantly and positively correlated with all PTSD factors; there were no differences in the strength of the suicidal ideation-PTSD factors relations. LimitationsThe studies were cross-sectional and relied on a single-item measure of suicidal ideation. DiscussionAll PTSD factors significantly and positively correlated with suicidal ideation, and the NACM and AAR PTSD clusters were most strongly associated with suicidal ideation in Study 1. Therefore, clinicians should be cautious to thoroughly screen patients with elevations on these PTSD cluster scores for suicide risk.
