Emotion regulation difficulties, low social support, and interpersonal violence mediate the link between childhood abuse and posttraumatic stress symptoms

We examined how difficulties with emotion regulation, social support, and interpersonal violence in adult relationships mediated the relationship between childhood abuse and post traumatic symptoms (PTS) in adults. We fit a multiple mediation model to data from 139 socio-economically disadvantaged women (85% African American) of whom 44% endorsed moderate to severe levels of childhood physical, sexual, or emotional abuse and 12% screened positive for probable posttraumatic stress disorder (PTSD). The model accounted for 63% of the variance in adult PTS symptoms. Child abuse exerted a direct effect on PTS symptoms and indirect effects through difficulties with emotion regulation, lower social support, and greater exposure to adult interpersonal violence. Implications of findings for the treatment of individuals at high risk of having experienced childhood abuse and PTS are discussed.

Interpersonal violence, PTSD, and inflammation: potential psychogenic pathways to higher C-reactive protein levels.

Interpersonal violence (IPV) is major public health concern with wide-ranging sequelae including depression, posttraumatic stress disorder (PTSD), and possible alterations of immune and inflammation processes. There is a need to identify the psycho-biological pathways through which IPV may translate to altered inflammatory processes since both PTSD and inflammation are associated with serious physical health conditions such as obesity, diabetes, and cardiovascular disease. This study investigated the relationships between IPV, psychological distress, and the inflammatory marker C-reactive protein (CRP), in a sample of 139 urban women who have a high likelihood for having experienced IPV. Participants were recruited from an outpatient gynecology clinic to complete self-report measures about their IPV histories and psychological symptoms, as well as to have their blood sampled using a finger stick. Results indicated that exposure to IPV predicted the presence of probable depression and PTSD diagnoses. Individuals who experience clinical levels of PTSD exhibited higher CRP levels, and this relationship held after adjusting for comorbid depression. Correlational analyses suggested that reexperiencing symptoms may explain the link between PTSD diagnosis and higher levels of CRP. Follow-up path analytic models provided good fit to the overall data, and indicated that the relationship between probable PTSD status and CRP is not explained by higher BMI. Overall, these findings call for increased attention to the role of PTSD in explaining links between trauma and diminished health.

Posttraumatic stress symptoms in palliative care professionals seeking mindfulness training: Prevalence and vulnerability

Background: Vicarious exposure to trauma is ubiquitous in palliative medicine. Repeated exposure to trauma may contribute to compassion fatigue and posttraumatic stress disorder symptoms in medical and supportive care professionals such as physicians, nurses, and social workers. These symptoms may be intensified among medical and supportive care professionals who use avoidant or rigid coping strategies. Aim: This study aimed to provide an estimate of posttraumatic stress disorder symptoms in a sample of professionals who work in palliative care settings, and have already been enrolled in mindfulness-based communication training. Design: Palliative care providers provided self-reported ratings of posttraumatic stress disorder symptoms, depression, and coping strategies using validated measures including the Acceptance and Action Questionnaire, Cognitive Fusion Questionnaire, and the Posttraumatic Stress Disorder Checklist–Civilian Version. Setting/participants: A total of 21 professionals working with palliative care patients completed assessments prior to beginning mindfulness-based communication training. Results: Posttraumatic stress disorder symptoms were prevalent in this sample of professionals; 42% indicated positive screens for significant posttraumatic stress disorder symptoms, and 33% indicated probable posttraumatic stress disorder diagnosis. Conclusion: Posttraumatic stress disorder symptoms may be common among professionals working in palliative medicine. Professionals prone to avoidant coping and those with more rigid negative thought processes may be at higher risk for posttraumatic stress disorder symptoms.

Anger arousal and behavioral anger regulation in everyday life among patients with chronic low back pain: Relationships to patient pain and function.

OBJECTIVE The objective of this study was to determine the degree to which patient anger arousal and behavioral anger regulation (expression, inhibition) occurring in the course of daily life was related to patient pain and function as rated by patients and their spouses. METHOD Married couples (N = 105) (one spouse with chronic low back pain) completed electronic daily diaries, with assessments 5 times/day for 14 days. Patients completed items on their own state anger, behavioral anger expression and inhibition, and pain-related factors. Spouses completed items on their observations of patient pain-related factors. Hierarchical linear modeling was used to test concurrent and lagged relationships. RESULTS Patient-reported increases in state anger were related to their reports of concurrent increases in pain and pain interference and to spouse reports of patient pain and pain behavior. Patient-reported increases in behavioral anger expression were related to lagged increases in pain intensity and interference and decreases in function. Most of these relationships remained significant with state anger controlled. Patient-reported increases in behavioral anger inhibition were related to concurrent increases in pain interference and decreases in function, which also remained significant with state anger controlled. Patient-reported increases in state anger were related to lagged increases in spouse reports of patient pain intensity and pain behaviors. CONCLUSIONS Results indicate that in patients with chronic pain, anger arousal and behavioral anger expression and inhibition in everyday life are related to elevated pain intensity and decreased function as reported by patients. Spouse ratings show some degree of concordance with patient reports.

Sleep disturbances predict later trauma-related distress: cross-panel investigation amidst violent turmoil.

OBJECTIVE Sleep disturbances, including trouble falling and remaining asleep and recurrent nightmares, are symptoms of posttraumatic stress. A growing body of literature indicates that sleep disturbance may also convey vulnerability for the continuation of other symptoms of posttraumatic stress, including fear, anxiety, and heightened arousal. However, longitudinal research, which could help understand how these relationships unfold over time, has been limited. METHOD The longitudinal relationships between sleep disturbance and posttraumatic stress were investigated in 779 Palestinian adults randomly selected and interviewed twice during the period from April 2008 to November 2008, amid ongoing violent political turmoil. The recruitment method produced a representative sample and excellent retention. Cross-panel structural equation modeling was used to examine relationships between sleep and distress across two study periods. RESULTS Results indicated that initial sleep problems were associated with increased posttraumatic stress disorder (PTSD), depression, and intrapersonal resource loss at follow-up 6 months later, but initial PTSD, depression, and intrapersonal resource loss were not associated with increased sleep problems at follow-up. CONCLUSIONS Sleep problems may confer vulnerability to longer-term distress in the presence of ongoing political violence. Future research should examine whether interventions targeting trauma-related sleep problems may improve prevention and treatment for PTSD and related disorders.

Mindfulness-Based Stress Reduction for Posttraumatic Stress Symptoms: Building Acceptance and Decreasing Shame

Mindfulness-based psychotherapies are associated with reductions in depression and anxiety. However, few studies address whether mindfulness-based approaches may benefit individuals with posttraumatic stress symptoms. The current pilot study explored whether group mindfulness-based stress reduction therapy reduced posttraumatic stress symptoms, depression, and negative trauma-related appraisals in 9 adult participants who reported trauma exposure and posttraumatic stress or depression. Participants completed 8 sessions of mindfulness-based stress reduction treatment, as well as pretreatment, midtreatment, and posttreatment assessments of psychological symptoms, acceptance of emotional experiences, and trauma appraisals. Posttraumatic stress symptoms, depression, and shame-based trauma appraisals were reduced over the 8-week period, whereas acceptance of emotional experiences increased. Participants’ self-reported amount of weekly mindfulness practice was related to increased acceptance of emotional experiences from pretreatment to posttreatment. Results support the utility of mindfulness-based therapies for posttraumatic stress symptoms and reinforce studies that highlight reducing shame and increasing acceptance as important elements of recovery from trauma.

Inflamed by the Flames? The Impact of Terrorism and War on Immunity

The physiological impact on citizens of prolonged exposure to violence and conflict is a crucial, yet underexplored, issue within the political science and biology literature. We examined the effect of high levels of exposure to rocket and terrorist attacks on biological markers of immunity and inflammation in a sample of 92 Israelis. A stratified random sample of individuals was drawn from a pool of subjects in Israel who had previously been interviewed regarding their stress exposure and psychological distress during a period of active rocket and terrorist attacks. These individuals were reinterviewed and blood samples were collected to assess antibodies to cytomegalovirus (CMV antibodies) and C-reactive protein (CRP). Posttraumatic stress disorder (PTSD) was significantly related to CRP, β = .33, p = .034, with body mass index, depression, and exposure to terrorism included in the model. Depression scores were not significantly associated with CRP or CMV antibody levels. In contrast to the established convention that psychological distress is the sole outcome of terrorism exposure, these findings reveal that individuals exposed to terrorism experience higher levels of both PTSD/depression, and inflammation. This study has important ramifications for how policy makers and medical health professionals should formulate public health policies and medically treat individuals living in conflict zones.

Traumatic Stress in Overview: Definition, Context, Scope, and Long-Term Outcomes

Trauma in the form of natural disasters, war, and other catastrophic events is ubiquitous. Exposure to traumatic events has been recognized as part of the human experience and has the potential to impact subsequent development across the life span, although individual responses to trauma vary widely. In this chapter, we discuss common sources of trauma and their long-term impacts from the perspective of conservation of resources (COR) theory. In brief, COR theory posits that traumatic stress is a dynamic psychological process that occurs in response to the rapid and often momentous loss of key valued resources. COR theory corollaries include the notions that loss is developmental and tends to occur in negative spirals, the impact of loss outweighs the positive impact of gain, and individuals with fewer reserves of resources are more sensitive to loss and gain (Hobfoll, Stress, culture, and community: The psychology and philosophy of stress, 2004). Common reactions to trauma such as posttraumatic stress disorder (PTSD) are introduced with an emphasis on how reactions unfold over time. Moreover, these reactions interact with the broader social context to produce cycles of loss observed at the individual, community, and cultural levels.

The Moderating effects of Cluster B Personality Traits on Violence Reduction Training: A Mixed-Model Analysis

Cognitive behavioral therapies have positive effects on anger and aggression; however, individuals differ in their response to treatment. The authors previously found that dynamic factors, such as increases in readiness to change, are associated with enhanced outcomes for violence reduction training. This study investigated how less dynamic factors, specifically Cluster B personality traits, moderate the effects of violence reduction training. The authors used mixed modeling to fit growth curves to 14 weeks of anger strategies data and evaluated whether the presence of Cluster B traits affected pretreatment anger levels and rates of change. As expected, overall levels of negative anger strategies decreased across the 14-week treatment. Participants with antisocial, borderline, and histrionic personality features reported higher rates of negative anger strategies, whereas those with narcissistic personality features reported fewer negative anger strategies. Those with antisocial personality features improved at a rate similar to the overall trend of those without Cluster B traits. Those with borderline and histrionic features improved at an accelerated rate.

Toward an Asset Orientation in the Study of U.S. Latina/o Youth: Biculturalism, Ethnic Identity, and Positive Youth Development

Despite their significant and growing demographic importance, U.S. Latina/o youth are rarely the focus of research and almost never studied from a perspective that reflects counseling psychologists’ emphases on social justice and the strengths of individuals. Such a perspective is likely to result in more effective approaches to the understanding and prevention of adverse outcomes and can expand the understanding of variables that have been traditionally used to study U.S. Latina/o youth. In this study, two specific asset variables—leadership and social responsibility—were used to test hypotheses about the role of biculturalism in adaptive psychological functioning among U.S. Latina/o youth. Results suggest that bicultural identity is meaningfully associated with asset variables, whereas bicultural involvement is not. Implications for research and practice are discussed.
