Sexual Trauma, Posttraumatic Stress Disorder, and Health Behavior

Abstract The authors tested whether sexual traumatization is associated with poorer health behavior and also evaluated the role of posttraumatic stress disorder (PTSD) in this relationship. They mailed questionnaires to 419 women who had visited a San Diego Veterans Administration primary care clinic in 1998 and received 221 responses, a 56% return rate. They found that a history of sexual assault was associated with increased substance use, risky sexual behaviors, less vigorous exercise, and increased preventive healthcare. They then used regression-based techniques to test whether PTSD mediates the relationship between a history of sexual assault and health behaviors and discovered support for this hypothesis in relation to substance use. PTSD symptoms were also associated with less likelihood of conducting regular breast self-examinations. Findings from the study highlight the value of programs designed to (1) identify trauma victims, (2) screen for problematic behaviors, and (3) intervene to improve long-term health outcomes.

Anxiety sensitivity as a predictor of labor pain.

Psychosocial factors have been implicated in the pain experience during childbirth, which can have both short‐ and long‐term consequences on the mothers health and her relationship with her infant. The present study evaluated important demographic, social, and psychological factors as predictors of multiple dimensions of labor pain among 35 mothers during childbirth. The results indicated that anxiety sensitivity (AS), as measured by the Anxiety Sensitivity Index, shared a significant relation with maximum pain during labor as well as sensory and affective components of pain as measured by the McGill Pain Questionnaire. AS predicted both maximum pain during labor and sensory aspects of pain above and beyond demographic and social factors as well as other theoretically important psychological factors (e.g., depression and state anxiety). These data replicate previous research that has demonstrated the significant impact of AS on pain responding in other areas (e.g., chronic pain) and extend knowledge in this literature to demonstrate the important role that AS serves among women and their experience of labor pain. Clinical implications are highlighted and discussed.

The Impact of Maternal Childhood Abuse on Parenting and Infant Temperament

The impact of maternal history of maltreatment and psychopathology on mother-child relationship, parenting, and infant temperament was evaluated. Women completed self-report measures addressing childhood trauma, psychopathology, infant-parent relationship, parenting, and infant temperament. Maternal physical abuse was associated with poorer mother-child interactions, increased vigilance, and difficulty recovering from distress among infants, whereas a history of emotional abuse was linked with less interactional dysfunction, lower levels of infant frustration, and more pleasure. Maternal depression was associated with infant temperament and attitudes about parenting. These findings suggest that maternal history of childhood abuse and psychopathology are important determinants of parenting and infant temperament.

Gender differences in childhood onset conduct disorder

The present study tested several predictions related to the theory that girls with conduct disorder (CD) follow a single delayed onset pathway. The following hypotheses were tested among a high-risk, stratified random sample of youth who used public services during a 6-month period: boys will be more likely to have childhood onset CD (COCD) than girls; girls with COCD will be less common than girls with adolescent onset CD (AOCD); COCD girls. AOCD girls, and COCD boys will be similar in terms of risk profiles and AOCD boys will have a less severe risk profile than COCD girls; and risk factors that differentiate between COCD and AOCD among males will not differentiate between COCD and AOCD among females. Among those youth who met the criteria for CD, males were significantly more likely to have COCD than females. However, close to half of females with CD met the criteria for the COCD subtype. Of the seven risk factors that were examined, girls with COCD scored higher than COCD boys on three factors and higher than AOCD girls on four factors; however, only one significant difference was found between AOCD girls and COCD boys. Finally, risk factors appeared to differentiate between COCD and AOCD groups in a similar way among males and females. These findings suggest that COCD is not rare among females in public service sectors, COCD girls can be distinguished from AOCD girls in terms of risk factors, and risk factors for COCD among males are also relevant to females.

Sexual trauma and pregnancy: a conceptual framework.

In this paper, we propose that a history of sexual traumatization is associated with pregnancy complications and poor pregnancy-related outcomes. We further hypothesize that this relationship is mediated by the sequelae of trauma (psychopathology, health problems, and increased negative health behaviors). We review the literature linking sexual trauma with psychopathology, health, and health behavior and then outline the impact of these variables on pregnancy. Based on this review, we draw conclusions about the potential impact of sexual trauma on pregnancy outcomes. We suggest future directions for this area of research and discuss the clinical implications of this association, including the development of prenatal intervention and prevention programs.

Associations of military sexual trauma, combat exposure, and number of deployments with physical and mental health indicators in Iraq and Afghanistan veterans.

Trauma exposure (TE) and numerous deployments have been associated with negative health outcomes in veterans, many of whom have military sexual trauma (MST) and combat exposure (CE). The aims of this study were to examine the relationships between physical and mental health symptoms with MST and CE and number of deployments. Iraq and Afghanistan veterans at the Veterans Affairs San Diego Healthcare System completed self-report measures for MST, CE, number of deployments, posttraumatic stress disorder (PTSD) symptoms, depression symptoms, alcohol use, somatic symptoms, health functioning, and body mass index (BMI). Regression analyses examined main and interaction effects of CE and MST and the linear and quadratic trends of number of deployments. The sample (N = 1,294) had a mean age of 31 and was 85% male. The MST by CE interaction on BMI was significant (p = .005), such that MST was associated with lower BMI in veterans with CE and with higher BMI in veterans without CE. MST and CE were associated with higher somatic, PTSD, and depression symptoms and with lower mental health functioning (ps < .001 to .002). CE was associated with lower physical health functioning and higher alcohol use (ps < .001 to .025). Number of deployments was linearly related to higher BMI (p = .004) and had a quadratic association with alcohol use (p = .008). Findings highlight the relationship between TE and poor health outcomes and the need to further study the mechanisms of TE on physical and mental health.

Evaluation of a hybrid treatment for Veterans with comorbid traumatic brain injury and posttraumatic stress disorder: Study protocol for a randomized controlled trial

Comorbidity of posttraumatic stress disorder (PTSD) and history of traumatic brain injury (TBI) is high among Veterans of Operation Iraqi Freedom/Enduring Freedom/New Dawn (OIF/OEF/OND). Cognitive processing therapy (CPT) is empirically supported for the treatment of PTSD, but it is not specifically designed to accommodate the memory, attention, or problem solving deficits that are experienced by many Veterans with comorbid PTSD and TBI. Compensatory cognitive rehabilitation, including cognitive symptom management and rehabilitation therapy (CogSMART), is effective for cognitive deficits stemming from a variety of etiologies, including TBI. We have integrated components of CogSMART into CPT in order to address the unique challenges faced by Veterans with ongoing cognitive complaints related to PTSD and a history of mild TBI. Here we describe an ongoing randomized controlled trial investigating the efficacy of our novel hybrid treatment, SMART-CPT, as compared to standard CPT, for OIF/OEF/OND Veterans with PTSD and a history of mild to moderate TBI. We describe the development of this hybrid treatment as well as implementation of the randomized controlled trial.

Contributions to Executive Dysfunction in Operation Enduring Freedom/Operation Iraqi Freedom Veterans With Posttraumatic Stress Disorder and History of Mild Traumatic Brain Injury

Objective: Posttraumatic stress disorder (PTSD), history of mild traumatic brain injury (mTBI), and executive function (EF) difficulties are prevalent in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans. We evaluated the contributions of injury variables, lower-order cognitive component processes (processing speed/attention), and psychological symptoms to EF. Participants: OEF/OIF Veterans (N = 65) with PTSD and history of mTBI were administered neuropsychological tests of EF and self-report assessments of PTSD and depression. Results: Those impaired on one or more EF measures had higher PTSD and depression symptoms and lower processing speed/attention performance than those with intact performance on all EF measures. Across participants, poorer attention/processing speed performance and higher psychological symptoms were associated with worse performance on specific aspects of EF (eg, inhibition and switching) even after accounting for injury variables. Although direct relationships between EF and injury variables were equivocal, there was an interaction between measures of injury burden and processing speed/attention such that those with greater injury burden exhibited significant and positive relationships between processing speed/attention and inhibition/switching, whereas those with lower injury burden did not. Conclusion: Psychological symptoms as well as lower-order component processes of EF (attention and processing speed) contribute significantly to executive dysfunction in OEF/OIF Veterans with PTSD and history of mTBI. However, there may be equivocal relationships between injury variables and EF that warrant further study. Results provide groundwork for more fully understanding cognitive symptoms in OEF/OIF Veterans with PTSD and history of mTBI that can inform psychological and cognitive interventions in this population.

Worse baseline executive functioning is associated with dropout and poorer response to trauma-focused treatment for veterans with PTSD and comorbid traumatic brain injury

Although trauma-focused treatment, including Cognitive Processing Therapy (CPT), effectively reduces PTSD symptoms, treatment dropout, nonresponse, and relapse are substantial. Executive functioning (EF) is essential to engage the cognitive skills involved in CPT (e.g., inhibiting/evaluating distorted thoughts, flexibly generating alternative thoughts). It was hypothesized that worse baseline EF would be associated with reduced CPT completion and responsivity. Seventy-four Iraq/Afghanistan-era Veterans with PTSD and history of mild-to-moderate traumatic brain injury were randomized to either standard CPT or modified CPT that included cognitive rehabilitation strategies (SMART-CPT). Those who dropped out of treatment prematurely performed more poorly on EF tests at baseline than treatment completers. Worse baseline performances on EF tests of working memory, inhibition, and inhibition/switching were associated with poorer response to CPT (less reduction in PTSD symptoms). In addition, a three-way interaction indicated that individuals with worse baseline cognitive flexibility did not benefit as much from standard CPT but demonstrated significant PTSD symptom improvement in the SMART-CPT condition, comparable to those with better baseline cognitive flexibility. Modifying CPT to accommodate executive dysfunction may boost treatment effectiveness and allow Veterans to fully engage in and benefit more from components of CPT (e.g., cognitive restructuring).
