The Role of Medical Specialization on Posttraumatic Symptoms in Pediatric Nurses

PurposeComparison of medical specialization of repeated exposure to secondary trauma and Post-Traumatic Stress Disorder (PTSD) symptoms in pediatric nurses was examined. Design and methodsThe PTSD Checklist-Civilian Version (PCL-C) was administered to 182 nurses over their first year on the job at a pediatric hospital (three time-points: baseline, 3 month follow-up, and 1 year follow-up). Demographic characteristics (age groups, gender, education, and race) and previous healthcare experience on whether nurses met criteria for no, partial, or full PTSD across all three time-points was examined. Differences in unit assignment on total PTSD symptoms and symptoms of each criterion of PTSD (re-experiencing, avoidance, and arousal) were also examined. ResultsNo significant differences of both demographic characteristics and previous healthcare experience were found on these PTSD categories. However, both ICU and Hematology/Oncology units were more at risk for developing partial and full PTSD, respectively compared to other units. Nurses in the rehabilitation units had significantly higher re-experiencing, avoidance, and arousal symptoms than those assigned to medical/surgical and intensive care units. ConclusionsResults demonstrate a need for hospitals to assess why nurses from certain units are reporting more PTSD symptoms and screen for PTSD symptoms and other mental health concerns throughout their career. Practice implicationsBeing aware of which units may be more at-risk should inform unit-specific prevention and intervention programs to decrease negative outcomes, including burnout, compassion fatigue, and job dissatisfaction.

Posttraumatic stress symptoms, fear and avoidance of driving, and aberrant driving behaviors. The moderating role of gender

IntroductionPrevious literature supports the fact that posttraumatic stress disorder (PTSD) symptomatology, as well as fear and avoidance of driving are possible consequences of road traffic crashes (RTC). The aim of the present study is to assess the relations between PTSD symptoms, fear and avoidance of driving, and aberrant driving behaviors, in a sample of Romanian drivers that were involved in an RTC in the last two years before conducting the study. Further, we wanted to identify the moderating role of gender in the relations between PTSD symptoms, fear and avoidance of driving, and aberrant driving behaviors. MethodA sample comprising 162 participants (62.3% were men, Mage = 29.37) was involved in the study. ResultsThe results showed that PTSD symptoms and a composite score of fear and avoidance of driving were positively associated with slips and lapses on the road and with the number of reported errors while driving. The path analysis revealed non-significant relations between fear and avoidance of driving and driving behaviors. Furthermore, multi-group analysis showed that the relations between PTSD symptoms and aberrant driving behaviors are significant only for men. ConclusionsThe implications of the results for traffic safety are discussed.

Post-traumatic stress disorder's relation with positive and negative emotional avoidance: The moderating role of gender.

Post-traumatic stress disorder (PTSD) is characterized by avoidance of trauma-related emotions. Research indicates that this avoidance may extend to any emotional experience that elicits distress, including those that are unrelated to the trauma. Literature in this area has been limited in its exclusive focus on negative emotions. Despite evidence of gender differences in PTSD and emotional avoidance separately, no studies to date have examined gender as a moderator of their association. The goal of the current study was to extend research by exploring the moderating role of gender in the relation between PTSD symptom severity and positive and negative emotional avoidance. Participants were 276 trauma-exposed individuals (65.9% female, 65.6% White, Mage = 19.24) from a university in the north-eastern United States. Moderation results indicated a main effect for PTSD symptom severity on both positive (b = 0.07, p < .001) and negative (b = 0.04, p = .03) emotional avoidance. The interaction of gender and PTSD symptom severity was significant for positive emotion avoidance (b = 0.97, p = .01). Analysis of simple slopes revealed that PTSD symptom severity was significantly associated with positive emotional avoidance for males (b = 0.13, p < .001) but not females (b = 0.03, p = .08). Results suggest the importance of gender-sensitive recommendations for assessment and treatment of emotional avoidance in PTSD.

Sleep Disturbance and PTSD Symptoms in Psychiatric Inpatients: the Role of Mindfulness Facets

Trauma exposure and posttraumatic stress disorder (PTSD) are significant concerns across psychiatric inpatient populations. Sleep disturbance is implicated in the etiology and maintenance of PTSD. Mindfulness facets, including observing, describing, acting with awareness, non-judging of inner experience, and non-reactivity to inner experience, may have clinical relevance to sleep disturbance and PTSD. No studies to date have examined associations among sleep disturbance, mindfulness facets, and PTSD symptom severity among psychiatric inpatients. Based upon the extant literature, greater sleep disturbance and lower acting with awareness, non-judging of inner experience, and non-reactivity to inner experience were expected to be associated with greater PTSD severity; sleep disturbance was expected to exert an indirect effect on PTSD severity through acting with awareness, non-reactivity to inner experience, and non-judging of inner experience. Covariates included trauma load and number of psychiatric diagnoses. Participants included 115 trauma-exposed psychiatric inpatients (40.0% female; Mage = 33.2, SD = 10.9). During an acute-care psychiatric inpatient hospitalization, participants were administered the Mini Mental Status Examination and completed a self-report packet, which included questionnaires used in the current investigation. Greater sleep disturbance and lower describing, acting with awareness, and non-judging of inner experience facets of mindfulness were each significantly associated with greater PTSD total symptom severity. Through non-judging of inner experience, sleep disturbance exerted an indirect effect on PTSD total symptom severity and the severity of PTSD symptom clusters, including intrusion, avoidance, negative cognitions and mood, and arousal and reactivity symptoms. Future research and clinical work may target the mindfulness facet of non-judging of inner experience in order to reduce the association between sleep disturbance and PTSD symptomatology among psychiatric inpatients.

Relation between PTSD symptom clusters and positive memory characteristics: A network perspective

Positive memory characteristics relate to posttraumatic stress disorder (PTSD) severity. We utilized a network approach to examine relations between PTSD clusters (intrusions, avoidance, negative alterations in cognitions and mood [NACM], alterations in arousal and reactivity [AAR]) and positive memory characteristics (count, accessibility, valence, vividness, coherence, time perspective, sensory details). We identified differential relations between PTSD clusters and positive memory characteristics, and central/bridging symptoms. Participants were an Amazon Mechanical Turk-recruited sample of 206 individuals (Mage = 35.36; 61.20% females). We estimated a regularized Gaussian Graphic Model comprising four nodes representing the PTSD clusters and six nodes representing positive memory characteristics. Regarding cross-community relations, AAR (highest node strength) was negatively associated with positive memory count, valence, coherence, and accessibility; avoidance was positively and negatively associated with positive memory vividness and count respectively. The NACM-AAR and intrusion-avoidance edges were significantly stronger than most edges. From the PTSD community, AAR and avoidance had the highest bridge strength and bridge expected influence respectively; from the positive memory community, coherence and vividness had the highest bridge strength and bridge expected influence respectively. Results indicate the potential pivotal role of AAR, avoidance, coherence, and vividness in the PTSD-positive memory relation, which renders them assessment/treatment targets pending further investigation.

High physical activity is associated with post-traumatic stress disorder among individuals aged 15 years and older in South Africa.

BackgroundSome research seems to suggest that physical activity (PA) was beneficial for post-traumatic stress disorder (PTSD).AimThis study examined the association between levels of PA and PTSD among individuals 15 years and above in South Africa.SettingCommunity-based survey sample representative of the national population in South Africa.MethodsIn all, 15 201 individuals (mean age 36.9 years) responded to the cross-sectional South African National Health and Nutrition Examination Survey (SANHANES-1) in 2012.ResultsOne in five (20.1%) of participants reported exposure to at least one traumatic event in a lifetime, and 2.1% were classified as having a PTSD, 7.9% fulfilled PTSD re-experiencing criteria, 3.0% PTSD avoidance criteria and 4.3% PTSD hyperarousal criteria. Almost half (48.1%) of respondents had low PA, 17.4% moderate PA and 34.5% high PA. In logistic regression analysis, adjusted for age, sex, population group, employment status, residence status, number of trauma types, problem drinking, current tobacco use, sleep problems and depressive symptoms, high PA was associated with PTSD (odds ratio [OR] = 1.75, confidence interval [CI] = 1.11–2.75), PTSD re-experiencing symptom criteria (OR = 1.43, CI = 1.09–1.86) and PTSD avoidance symptom criteria (OR = 1.74, CI = 1.18–2.59), but high PA was not associated with PTSD hyperarousal symptom criteria. In generalised structural equation modelling, total trauma events had a positive direct and indirect effect on PTSD mediated by high PA, and high PA had a positive indirect effect on PTSD, mediated by psychological distress and problem drinking.ConclusionAfter controlling for relevant covariates, high PA was associated with increased PTSD symptomatology.

Influence of affective distractors on working memory capacity in relation to symptoms of posttraumatic stress disorder

SummarySymptoms evoked in individuals with posttraumatic stress disorder (PTSD) when processing trauma‐relevant material arguably impair higher order cognitive functions. An example is working memory capacity (WMC), which has been shown to be disrupted by affective distractors. However, it is unknown whether this association varies across different types of PTSD symptoms. This study explored the association between WMC performed in affective (relative to neutral) contexts in relation to different symptoms of PTSD (avoidance, re‐experiencing, hyperarousal). Motor vehicle accident survivors with PTSD and without PTSD completed a delayed‐match‐to‐sample task including trauma‐related, neutral, and scrambled distractors in the interval between the presentation of the memoranda and the recognition target. The results showed that there was support for an indirect pathway between PTSD diagnosis and WMC performed in affective (versus neutral) contexts through re‐experiencing and avoidance symptoms. The findings suggest that avoidance symptoms in particular may benefit from interventions directed at improving WMC.

Psychological inflexibility predicts PTSD symptom severity in war veterans after accounting for established PTSD risk factors and personality.

Numerous risk factors for posttraumatic stress disorder (PTSD) have been identified; however, many do not inform treatment. Psychological inflexibility is a modifiable factor that can be targeted in psychological treatment. This study examined whether higher levels of psychological inflexibility predicted unique variance in PTSD symptom severity at 1-year follow-up in 236 U.S. veterans of the wars in Iraq in Afghanistan after accounting for the strongest known risk factors for PTSD. PTSD symptom severity was assessed using the Clinician Administered PTSD Scale. In hierarchical regression analyses, higher baseline psychological inflexibility predicted unique variance in 1-year PTSD symptom severity (p < .001, medium effect) after accounting for the strongest predictors, including: serving in the Army, rank, trauma severity, perceived threat, peritraumatic dissociation, recent life stress, and social support. Psychological inflexibility remained a significant predictor of unique variance in 1-year PTSD symptom severity after accounting for all other predictors and personality factors (neuroticism, extroversion, openness to experience, agreeableness, and conscientiousness; p < .001, small effect) and after accounting for all other predictors, personality factors, and baseline PTSD avoidance symptoms (p < .001; small effect). Findings indicate a key unique association between psychological inflexibility and PTSD symptom severity over time that is not attributable to overlap with personality or PTSD avoidance symptoms. Additional research on psychological inflexibility in the development and maintenance of PTSD is warranted, as well as whether increasing psychological flexibility leads to reductions in PTSD symptoms and improved psychosocial functioning.

Attention bias toward threatening faces in women with PTSD: eye tracking correlates by symptom cluster

ABSTRACT Maladaptive patterns of attention to emotional stimuli are a common feature of posttraumatic stress disorder (PTSD), with growing evidence supporting sustained attention to threatening stimuli across trauma samples. However, it remains unclear how different PTSD symptom clusters are associated with attentional bias patterns, particularly in urban civilian settings with high rates of trauma exposure and PTSD. The present study examined associations among these variables in 70 traumatized primarily African American women. PTSD was measured using the Clinician Administered PTSD Scale, and eye tracking was used to measure patterns of attention as participants engaged in an attention bias (dot probe) task to emotional faces; average initial fixation (1 s) and dwell duration (overall time spent looking at emotional face versus neutral face across the 5 s task) were used to assess attention bias patterns toward emotional faces. Women with PTSD showed significantly longer dwell duration toward angry faces than women without PTSD (F = 5.16, p < .05). Bivariate correlation analyses with the PTSD symptom clusters showed a significant association between average initial fixation toward angry faces and higher levels of avoidance symptoms (r = 0.29, p < .05) as well as sustained attention to angry faces and higher levels of re-experiencing symptoms (r = 0.24, p < .05). Using separate linear regression models based on initial significant correlations, we found that PTSD avoidance symptoms were significantly related to average initial fixation toward angry faces (R 2 ∆ = 0.09, p < .05) and PTSD re-experiencing symptoms were significantly related to dwell duration toward angry faces (R 2 ∆ = 0.06, p < .05). These findings contribute to evidence that PTSD is related to both initial vigilance and sustained attention to threat and that certain symptom clusters may either drive or be more impacted by attentional biases, highlighting the benefits of addressing attentional biases within treatment.

Intolerance of uncertainty and DSM-5 PTSD symptoms: Associations among a treatment seeking veteran sample

Intolerance of uncertainty (IU), defined as an inability to tolerate the unpleasant response triggered by the observed absence of information, has received increased empirical attention in recent years. The contribution of this cognitive behavioral construct to the etiology and maintenance of various anxiety disorders has become increasingly recognized. However, the relationship between IU and other affective disorders, including posttraumatic stress disorder (PTSD), remains largely unexplored. The current study sought to examine the relationship between IU and overall PTSD symptom and cluster severity using an outpatient sample of veterans (N = 116) assessed using the Diagnostic and Statistical Manual of Mental Disorders, Fifth edition (DSM-5) PTSD symptom structure. Results revealed that IU was significantly associated with overall PTSD symptom severity, above and beyond relevant covariates. Further, IU was significantly associated with the PTSD avoidance and hyperarousal clusters. Prospective IU, rather than inhibitory IU, accounted for these unique associations. These findings add to a growing body of literature establishing IU as a transdiagnostic risk factor and point to the importance of future research on the role of IU in contributing to and/or maintaining PTSD symptoms.

Trauma Memory Processing in Posttraumatic Stress Disorder Psychotherapy: A Unifying Framework

Trauma memory processing (TMP) is an empirically supported approach to psychotherapy for posttraumatic stress disorder (PTSD). However, TMP is not a single, uniform intervention but instead a paradigm that can be operationalized through a variety of component procedures that have not been systematically elucidated and formally tested. Based on findings from phenomenological/structural and neuroimaging research, a central feature of PTSD is theorized to be the involuntary immersion in trauma memories with diminished awareness or negative appraisals of self and current context. Such intrusive reexperiencing-which is epitomized by, but not limited to, flashbacks-is postulated to underlie PTSD's avoidance, altered emotions and cognitions, dissociative, and hyperarousal/hypervigilance symptoms; it is thus a logical target for TMP. The varied approaches to TMP for PTSD are conceptualized as having the common goal of activation of the neural networks in the brain that underlie two key capacities disrupted by intrusive reexperiencing in PTSD: intentional self-referential retrieval of memories and suppression of memory retrieval. Therefore, TMP is postulated to involve two core functions (purposeful reflective remembering and memory awareness in situ) and three essential types (in vivo, imaginal, and cognitive reappraisal). Several implications of this framework for clinical practice and research on TMP for PTSD are discussed.

Predicting Avoidance Symptoms in U.S. Latino Youth Exposed to Community Violence: The Role of Cultural Values and Behavioral Inhibition.

Not all youth exposed to violence are at equal risk for developing posttraumatic stress disorder (PTSD), reflecting potential variability in risk factors influencing the development of PTSD beyond exposure to violence. In particular, Latino youth have been found to be at a higher risk for developing PTSD after exposure to violence. Similarly, youth with high levels of behavioral inhibition appear to be at greater risk of developing PTSD following exposure to violence. In this study, we examined how Latino cultural values might be associated with behavioral inhibition and how these two factors together may interact to predict risk for developing PTSD avoidance symptoms, specifically. Data from a longitudinal sample of 168 Latino adolescents (11-15 years of age) indicated that Latino values were positively associated with behavioral inhibition, r = .26, p < .001, and that Latino values moderated the association between behavioral inhibition and avoidance symptoms, β = .16, p = .009, such that the association was stronger as Latino cultural values increased. Results from this study highlight the importance of considering cultural, individual, and contextual factors for understanding risk for PTSD. Future research should further assess the biological and cultural correlates of behavioral inhibition in order to improve understanding of risk and increase effectiveness of individualized intervention approaches.

Locus of control in US combat veterans: Unique associations with posttraumatic stress disorder 5-factor model symptom clusters

Given elevated rates of posttraumatic stress disorder (PTSD) among US military veterans, identifying correlates of PTSD and specific PTSD symptom clusters that best represent PTSD in veterans (i.e., the five-factor Dysphoric Arousal model) is critical to prevention and intervention efforts. One potential correlate is locus of control (i.e., the extent to which individuals believe they have control over events in their lives). The aim of this study was to examine the relations between locus of control and five-factor model PTSD symptom clusters (i.e., re-experiencing, avoidance, numbing, dysphoric arousal, anxious arousal) among combat veterans. Eighty-nine combat exposed veterans completed self-report measures of demographics, locus of control, PTSD symptoms, and combat exposure. Bivariate correlations indicated relations between locus of control and overall PTSD symptoms, avoidance symptoms, and numbing symptoms. When controlling for sex and combat exposure in regression analyses, only avoidance remained a significant correlate of locus of control. Among veterans with the most extreme scores (n = 26), external locus of control predicted overall PTSD symptoms and avoidance symptoms. External locus of control is uniquely associated with avoidance symptoms, and represents a potentially modifiable factor to address in trauma-focused treatments.

Influence of adjuvant mindfulness-based cognitive therapy (MBCT) on symptoms of post-traumatic stress disorder (PTSD) in veterans – results from a randomized control study

Even 30 or more years after the end of a war, veterans can suffer from post-traumatic stress disorder (PTSD). In the present study, we explored the influence on symptoms of PTSD among Iranian veterans of the Iran–Iraq war of mindfulness-based cognitive therapy (MBCT) as add-on to a standard treatment with citalopram. Forty-eight male veterans with PTSD (mean age: 52.97 years) took part in this eight-week intervention study. Standard treatment for all patients consisted of citalopram (30–50 mg/day at therapeutic dosages). Patients were randomly assigned either to the treatment or to the control condition. Treatment involved MBCT delivered in group sessions once a week. Patients in the control condition met at the hospital with the same frequency and duration for socio-therapeutic events. At baseline and at study completion, patients completed questionnaires covering symptoms of PTSD, depression, anxiety, and stress. At study completion after eight weeks, scores for PTSD (re-experiencing events, avoidance, negative mood and cognition, hyperarousal), depression, anxiety, and stress were lower, but more so in the intervention than the control group. Data suggest that, as adjuvant to standard SSRI medication, MBCT is an effective intervention to significantly reduce symptoms of PTSD, depression, anxiety, and stress among veterans.

Cumulative childhood interpersonal trauma is associated with reduced cortical differentiation between threat and non-threat faces in posttraumatic stress disorder adults.

Posttraumatic stress disorder and childhood trauma frequently co-occur. Both are associated with abnormal neural responses to salient emotion stimuli. As childhood trauma is a risk factor for posttraumatic stress disorder, differentiating between their neurophysiological effects is necessary to elucidate the neural pathways by which childhood trauma exposure contributes to increased posttraumatic stress disorder risks. Face-specific N170 evoked response potentials for backward-masked (non-conscious) and conscious threat (fear, angry) and non-threat (happy) faces were measured in 77 adults (18-64 years old, 64% women, 78% right-handed) symptomatic for posttraumatic stress disorder. Differences in N170 peak amplitudes for fear-versus-happy and angry-versus-happy faces at bilateral temporo-occipital (T5, T6) sites were computed. The effect of cumulative exposure to childhood interpersonal trauma, other childhood trauma, adult trauma, depression and posttraumatic stress disorder symptom severity on the N170 response was assessed using hierarchical multiple regression analyses. T5 N170 peak amplitudes for non-conscious fear-versus-happy faces were inversely related to cumulative childhood interpersonal trauma after accounting for socio-demographic, clinical symptom and other trauma factors. Posttraumatic stress disorder Avoidance was positively associated with N170 peak amplitudes for non-conscious fear-versus-happy faces, primarily due to reduced N170 responsivity to happy faces. Childhood interpersonal trauma exposure is associated with reduced discrimination between fear and happy faces, while avoidance symptom severity is associated with dampened responsivity to automatically processed happy faces in posttraumatic stress disorder adults. Results are discussed in terms of the likely contributions of impaired threat discrimination and deficient reward processing during neural processing of salient emotion stimuli, to increased risks of posttraumatic stress disorder onset and chronicity in childhood interpersonal trauma-exposed adults.

The relationship between distress tolerance regulation, counterfactual rumination, and PTSD symptom clusters

BackgroundDistress tolerance (DT) and rumination both influence the development and maintenance of posttraumatic stress disorder (PTSD). However, few studies have investigated these constructs simultaneously. We investigated whether the regulation dimension of DT was associated with PTSD symptom clusters (intrusions, avoidance, negative alternations in cognitions and mood, alterations in arousal and reactivity), and whether counterfactual rumination (CFT) mediated these relationships. MethodsThis cross-sectional study sampled trauma-exposed adults (N = 119) seeking mental health services at a community mental health center. Participants completed self-report measures of DT, rumination, and PTSD. Mediation analyses were conducted using the SPSS PROCESS Macro. ResultsLower scores on the DT regulation dimension were associated with higher PTSD symptom severity for all four symptom clusters, controlling for depression and number of traumas. CFT significantly mediated this relationship between DT's regulation and PTSD's intrusions and avoidance symptoms. LimitationsLimitations included use of self-report data and the cross-sectional nature of this data. ConclusionsClinically, this study highlights that difficulties with regulating negative emotions can result in the use of maladaptive cognitive strategies, such as CFT. This, in turn, may exacerbate PTSD symptom severity, particularly intrusions and avoidance. This study highlights the importance of understanding specific dimensions of DT, rumination, and PTSD symptom clusters to develop precise and efficient psychological interventions.

Predictors of remission from PTSD symptoms after sexual and non-sexual trauma in the community: A mediated survival-analytic approach

Epidemiological data on the chronicity of posttraumatic stress disorder (PTSD) symptoms in relation to trauma type and underlying pathways are rare. The current study explored how PTSD symptoms change over time across different trauma types and examined mediators of their persistence. A trauma-exposed community sample, whereof approximately one quarter met diagnostic criteria for PTSD, provided retrospective data on the duration of PTSD symptoms. Those who remitted and those who had not at the time of assessment were compared regarding worst trauma, symptom severity, comorbidity, demographic and treatment-seeking variables. Time to remission was estimated using Cox proportional hazard models including candidate predictors of remission. A mediated survival analysis was used to explore indirect pathways that explain trauma-specific differences in remission times. Both the full sample and PTSD subgroup were analyzed separately. Overall, lower socio-economic status, lifetime and childhood sexual trauma, symptom severity, comorbid depression and past treatment were associated with non- and longer remissions. PTSD avoidance symptoms and comorbid depression were found to mediate longer remission times after lifetime or childhood sexual trauma. Our findings provide insight into the mechanisms and complicating factors of remission from PTSD symptoms after trauma, which might have important implications for therapeutic interventions.

Predictive Validity of ICD-11 PTSD as Measured by the Impact of Event Scale-Revised: A 15-Year Prospective Study of Political Prisoners.

The 11th edition of the International Classification of Diseases (ICD-11; World Health Organization, 2017) proposes a model of posttraumatic stress disorder (PTSD) that includes 6 symptoms. This study assessed the ability of a classification-independent measure of posttraumatic stress symptoms, the Impact of Event Scale-Revised (Weiss & Marmar, 1996), to capture the ICD-11 model of PTSD. The current study also provided the first assessment of the predictive validity of ICD-11 PTSD. Former East German political prisoners were assessed in 1994 (N = 144) and in 2008-2009 (N = 88) on numerous psychological variables using self-report measures. Of the participants, 48.2% and 36.8% met probable diagnosis for ICD-11 PTSD at the first and second assessments, respectively. Confirmatory factor analysis supported the factorial validity of the 3-factor ICD-11 model of PTSD, as represented by items selected from the Impact of Event Scale-Revised. Hierarchical multiple regression analysis demonstrated that, controlling for sex, the symptom clusters of ICD-11 PTSD (reexperiencing, avoidance, and sense of threat) significantly contributed to the explanation of depression (R2 = .17), quality of life (R2 = .21), internalized anger (R2 = .10), externalized anger (R2 = .12), hatred of perpetrators (R2 = .15), dysfunctional disclosure (R2 = .27), and social acknowledgment as a victim (R2 = .12) across the 15-year study period. Current findings add support for the factorial and predictive validity of ICD-11 PTSD within a unique cohort of political prisoners.

Attachment Dimensions and Post-traumatic Symptoms Following Interpersonal Traumas versus Impersonal Traumas in Young Adults in Taiwan.

Greater risk of post-traumatic stress disorder (PTSD) is seen in individuals exposed to interpersonal traumatic events. Based on an attachment perspective, interpersonal trauma exposure may activate one's attachment insecurity system and disrupt affect, behaviour and interpersonal function, which may in turn create more difficulties to cope with interpersonal traumas and exacerbate PTSD symptomatology. The present study examined whether attachment anxiety relative to attachment avoidance would be a stronger predictor of greater PTSD symptoms following interpersonal traumas versus impersonal traumas in a Taiwanese sample. One hundred and sixty-two trauma-exposed Taiwanese young adults completed the measures of symptoms of depression, anxiety and PTSD, and attachment anxiety and attachment avoidance. In this Taiwanese study, higher attachment anxiety was observed in individuals who were exposed to interpersonal traumas. The interpersonal trauma group reported greater PTSD symptoms than did the impersonal trauma group. Specifically, after controlling for age, occurrence of trauma and distress of trauma, attachment anxiety, but not attachment avoidance, predicted more PTSD total severity and avoidance symptoms in the interpersonal trauma group. The findings may be pertinent to attachment anxiety-related hyperactivating strategies, as well as specific cultural values and a forbearance strategy applied to regulate traumatic distress in a collectivist society.

Associations Between Posttraumatic Stress Disorder, Emotion Dysregulation, and Alcohol Dependence Symptoms Among Inner City Females.

ObjectiveThe purpose of this study was to examine how emotion dysregulation (ED) might help explain the relationship between posttraumatic stress disorder (PTSD) and alcohol dependence (AD) symptoms in females.MethodParticipants included 260 women from primary, diabetes, and gynecological clinics of an urban public hospital. This is a primarily African American sample (96.9%), including individuals reporting exposure to at least 1 traumatic event. We examined the associations and predictability patterns between severity of PTSD symptoms, ED, and AD symptoms.ResultsUsing linear regression analyses, PTSD avoidance and numbing symptoms and ED were significant predictors of AD symptoms. When looking at specific dimensions of ED, one's inability to engage in goal‐directed behavior under strong emotional influences showed a full indirect effect on the relationship between PTSD avoidance and numbing symptoms and AD symptoms.ConclusionOur findings suggest that having poor emotion regulation skills may help explain why females with PTSD become dependent on alcohol.
