Toward an Integrated Theoretical Model of Risk Factors for Post-Deployment PTSD and its Implications for Justice-Involved Veterans

At present, very little knowledge exists about individual differences in susceptibility to posttraumatic stress disorder (PTSD) after combat trauma. Two differing perspectives have emerged. Some researchers maintain that a distinct linear dose-response relationship exists between the severity of combat trauma and the later development of PTSD. Conversely, others have questioned whether differential exposure to combat alone is sufficient to explain differences in the prevalence of post-deployment PTSD. This debate has implications for military veteran offenders who suffer from PTSD. In this paper, I propose a cumulative stress model that posits that it is the particular combination of psychosocial factors and combat exposure that interact to predict the likelihood of developing and maintaining PTSD after deployment. Therefore, PTSD influences post-deployment offending and antisocial behavior through this mechanism. Finally, this paper will discuss implications for criminal justice policy and practice.     

A life course approach: research orientations and future challenges

The need to study lifelong changes in health and functioning has resulted in increasing emphasis on a life course approach in different fields of inquiry. The aim of this approach is to explore how biological, psychological, and social risk factor trajectories, acting across the entire life course, influence age-related diseases, functional decline, and disability. The importance of the first years of life upon later development and adult characteristics was generally recognized already in the first half of the twentieth century, but it was not until the 1990s that different strands of medical and social research converge in the field of life course epidemiology, in which epidemiological processes are approached using different models such as biological programming, critical periods, pathways, and accumulation. The biological programming model holds that organ development in utero and early infancy determines the maximum functional capacity that an individual can attain and influences the development of certain chronic diseases later in life. The critical period model extends the idea to include child development and key social transitions over the entire life course. The pathway model focuses on the cumulative effect of life events along the developmental trajectories, with early advantage or disadvantage setting a person on a pathway to a later etiologically important exposure. The accumulation model describes the underlying social, behavioral, and biological processes that drive the impact of the life course on health. The growing focus on life course determinants of aging also has implications for studies of long-term changes in physical activity and their role in determining both gains and losses of health and functioning with aging. A life course approach presents great challenges for the continued development of testable theoretical models and effective study design and analysis.     

CREATING HEALING RELATIONSHIPS FOR COUPLES DEALING WITH TRAUMA: THE USE OF EMOTIONALLY FOCUSED MARITAL THERAPY

Emotionally focused marital therapy (EFT), a marital therapy that particularly focuses on the creation of secure attachment, has proven in empirical studies to be effective for distressed couples. This paper discusses the application of EFT in couples where one or both of the partners have experienced significant trauma. EFT, in this context of trauma, incorporates the nine steps of conventional EFT and also encompasses the three stages of the "constructivist" self development theory of trauma treatment. This paper illustrates how the integration of EFT and trauma treatement can prove effective in treating not only relationsip distress but also the individual symptoms of posttraumatic stress disorder (PTSD).     

Conceptualizing Childbearing Ambivalence: A Social and Dynamic Perspective

Childbearing ambivalence is often conceptualized as a state of conflicting desires about having a child that is characteristic of particular individuals or life stages. This study proposes that childbearing ambivalence is dynamic and situational, resulting from the multiple sociocultural frames surrounding childbearing. Using eight waves of prospective data from a population‐based sample of young adults in Malawi, results show that 41% of women and 48% of men are ambivalent about childbearing at some point in the 2.5‐year study. There is limited evidence that ambivalence is related to individual sociodemographic or psychosocial characteristics aside from gender; rather, ambivalence is tied to life course markers such as school enrollment and age. In addition, life course transitions and changes in relationships, health, and economic factors are associated with the onset of ambivalence, supporting the theory that ambivalence is a dynamic state that men and women frequently pass through as their lives and circumstances change.     

Life course analysis of gambling trajectories: an Indigenous Australian study

Traditional card gambling is a culturally acceptable recreational activity for generations of Indigenous Australians. Commercial gambling activities are popular as well. This study drew on a life course approach and a sample of 57 Indigenous Australian people to examine their gambling trajectories over time that resulted in recreational gambling or in disordered gambling. To gain in-depth insight into various gambling trajectories, this study used an interpretative phenomenological methodology. At early childhood, teenage, young adult and mature adult stages, major gambling influences appeared as dependence, independence, timing of major shifts and transitions, and rationalization, respectively. The study showed that being a recreational or disordered gambler was a shifting or fluctuating position, subject to transitions and events in people's lives rather than a one-way path in either direction. Within a complex cultural environment, the dynamic interplay between social density, context and individual choice appears to influence gambling trajectories for these Indigenous Australians.     

Past‐Year Sexual Inactivity Among Older Married Persons and Their Partners

Family scholars have focused on the onset of sexual activity early in the life course, but little is known about the cessation of sexual activity in relationships in later life. We use event‐history analysis techniques and logistic regression to identify the correlates of sexual inactivity among older married men and women. We analyze data for 1,502 married people from the National Social Life, Health, and Aging Project, a nationally representative sample of 3,005 noninstitutionalized American men and women ages 57 to 85. We find 29% of the married persons report no sexual activity for the previous 12 months or more. Relationship duration, chronological age, and poor physical health are all independently associated with sexual inactivity. Characteristics such as marital happiness, premarital cohabitation, and remarriage are also associated with levels of inactivity or activity. Analyses also point to gender differences in the correlates of sexual inactivity.     

Acute stress reactions to everyday stressful life events among sexual abuse survivors with PTSD

This study examined symptoms of Acute Stress Disorder (ASD), which is often thought of as a precursor to PTSD, among 54 women who already had PTSD for childhood sexual abuse for which they were seeking treatment. We examined the prevalence of ASD symptoms as well as their relationships to trauma symptoms measured by the Trauma Symptom Checklist-40. The ASD diagnosis requires the occurrence of a traumatic life event as well as meeting specific symptoms criteria. We found that fourty-four percent of participants met all symptom criteria for ASD, but only three of these 24 participants described a traumatic life event. Moreover, ASD symptoms were significantly related to trauma symptom scores. These findings suggest that a significant proportion of women with PTSD for childhood sexual abuse may be highly symptomatic for everyday stressful events that would not be experienced as traumatizing to others. Thus, these individuals need assistance in coping with everyday life stressors that do not involve a serious threat or injury in addition to needing help to alleviate their trauma symptoms.     

Offending Trajectories Among Native‐Born and Foreign‐Born Hispanics to Late Middle Age

Research on crime over the life‐course has made considerable progress in the last several decades. Despite this growth, significantly less attention has been devoted to longitudinal examinations of Hispanic populations beyond one phase of the life‐course, and/or examining differences between native‐born and foreign‐born Hispanics. Recognizing these limitations, this study offers an investigation of Hispanics in the United States focusing on offending and its relationship to immigration status. Using arrest data from a cohort of 375 Hispanic males from ages 18 to 50, trajectory analysis revealed four unique offending trajectories: very low‐rate offenders, high‐rate late‐onset escalators, initially high‐rate desisters, and high‐rate chronic offenders. Multivariate regression models demonstrated that Hispanic immigrants were significantly less likely to be initially high‐rate desisters or high‐rate chronic offenders compared with their native‐born counterparts, yet unmarried Hispanics were significantly more likely to be high‐rate late‐onset escalators. Study limitations and implications are also discussed.     

Evaluating a multiple-family group access intervention for refugees with PTSD

The purpose of this study was to analyze the effects of a multiple-family group in increasing access to mental health services for refugees with posttraumatic stress disorder (PTSD). This study investigated a nine-session multiple-family group called Coffee and Families Education and Support with refugee families from Bosnia-Herzegovina in Chicago. Adults with PTSD (n = 197) and their families were randomly assigned to receive either the intervention or a control condition. The results indicated that a multiple-family group was effective in increasing access to mental health services and that depression and family comfort with discussing trauma mediated the intervention effect. Further well-designed studies of family interventions are needed for developing evidence-based interventions for refugee families.     

Does writing reduce posttraumatic stress disorder symptoms?

To see if writing about their trauma lessened PTSD and related symptoms, 57 undergraduates, previously screened for traumatic experiences, wrote for 15 minutes on 4 days across 2 weeks about either their trauma or a trivial topic. They reported PTSD, impact, suicide ideas, dissociation, and depression pre-, post-, and at 6-week follow-up testing. Trauma and trivial writers were not different. Surprisingly, at follow-up everyone reported less severe PTSD symptoms, impact, and dissociation, and fewer health visits, but about the same suicidal ideation and depression. On PTSD symptoms and impact, the pattern of improvement was different: Those writing about trauma got worse at posttesting, but improved to better than their initial state by follow-up. Those writing about a trivial topic got better by posttesting, and held that position at follow-up. In this project, writing seemed to reduce PTSD symptoms regardless of whether it concerned the trauma or what they ate for lunch.     

Interactions between task repetition and psychosocial factors

Psychosocial factors, individual factors, workplace requirements, and workplace organizational factors have all been reported as being associated with the risk of musculoskeletal disorders [11]. Huang, Feuerstein, and Sauter [5] described the various concepts and models proposed to link occupational stress and work-related upper extremity disorders, as well as the difficulty in verifying the suggested linkages. Huang et al. [5] suggested that decomposing a complex model would be an appropriate method to begin the investigations of the proposed models. Task repetition is a workplace requirement that is considered a potential risk factor for cumulative trauma and its relationship to psychosocial factors was investigated. The study found only weak to no statistically significant relationship between task repetition and reported psychosocial factors of job stress in workers in Taiwan.     

Correlates of comorbid PTSD and polysubstance use in sexual assault victims

A diverse sample of community-residing women in a large metropolitan area who had experienced adult sexual assault was surveyed using standardized measures in an NIAAA-funded study (2003-2004). Four groups (N = 503) of victims: (1) post-traumatic stress disorder (PTSD)-only, (2) PTSD and illicit drug use, (3) PTSD and drinking problems, and (4) PTSD and polysubstance use were compared using bivariate analyses. Victims with PTSD/polysubstance use had lower socioeconomic status, more extensive trauma histories, worse current psychological functioning, more problematic post-assault psychosocial experiences, and more sexual revictimization at follow-up than those with PTSD only. Implications for future research are discussed.     

Adjustment to disability

This article will focus on the biopsychosocial challenges encountered when an individual is disabled at an early age as well as when an individual acquires a disability later in life. Two case examples will focus on the adaptations/life choices that are necessary to adequately meet psycho/social/developmental needs and enhance individual self esteem. The case of Rita, a woman who lost her hearing at age two, highlights the importance of integrating a biopsychosocial approach to understand the multiple challenges and adaptations of individuals who are disabled at an early age. Laureen, a woman who acquired a spinal cord injury during her late teen years, described her struggles as a young adult adapting to a physical disability. Both cases highlight the importance of integrating an ecological/systems framework focusing on a biopsychosocial perspective, emphasizing the interrelationship between biological, psychological, social, technological, cultural and political factors.     

Quality of life in workplace trauma victims seeking treatment for posttraumatic stress disorder

Traumatic events at work can have debilitating effects on employees. This pilot study aims to describe the trauma exposure, posttraumatic stress disorder (PTSD) severity, functioning level, and general and work-related quality of life of employees who experienced a workplace trauma and consequently developed PTSD. Forty-four participants with current PTSD were recruited and assessed using semistructured interviews and questionnaires. ANOVAs were performed to assess differences in outcomes between employees from different work settings. Specific types of traumatic events appear to occur in particular types of occupations. Participants manifested severe PTSD, low levels of current functioning, and poor general and work-related quality of life. Overall, these results did not significantly differ between employees in different occupations. Unemployed participants showed poorer outcomes than those who were still working despite their current difficulties. PTSD severity and the presence of comorbid major depression significantly predicted several quality-of-life outcomes. In conclusion, PTSD stemming from workplace trauma appears to have major consequences for employees. Clinical implications are discussed.     

Systemic traumatic stress: the couple adaptation to traumatic stress model

Research traditionally has focused on the development of symptoms in those who experienced trauma directly but overlooked the impact of trauma on the families of victims. In recent years, researchers and clinicians have begun to examine how individual exposure to traumatic stress affects the spouses/partners, children, and professional helpers of trauma survivors. However, empirically supported, theory-based literature that identifies the mechanisms by which interpersonal or "secondary trauma" occurs in response to traumatic events is limited. Here, we present the Couple Adaptation to Traumatic Stress Model, a systemic model of the development of interpersonal symptoms in the couple dyad based on empirical literature. Potential mechanisms and clinical vignettes are included to describe the systemic processes that occur with trauma couples. Areas for future research and clinical implications also are identified.     

Alcohol use trajectories and problem drinking over the course of adolescence: a study of north american indigenous youth and their caretakers

This study investigated the links between alcohol use trajectories and problem drinking (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition abuse/dependence) using five waves of data from 727 North American Indigenous adolescents between 10 and 17 years from eight reservations sharing a common language and culture. Growth mixture models linking fundamental causes, social stressors, support, and psychosocial pathways to problem drinking via alcohol use trajectories over the early life course were estimated. Results indicated that 20 percent of the adolescents began drinking at 11 to 12 years of age and that another 20 percent began drinking shortly thereafter. These early drinkers were at greatly elevated risk for problem drinking, as were those who began drinking at age 13. The etiological analysis revealed that stressors (e.g., perceived discrimination) directly and indirectly influenced early and problem alcohol use by decreasing positive school attitudes while increasing feelings of anger and perceived delinquent friendships. Girls were found to be at risk independently of these other factors.     

Characteristics of urban male homeless veterans and non-veterans in Omaha,Nebraska

The current study examined differences between urban homeless veterans and non-veterans on sociodemographics, housing, clinical characteristics, and psychosocial factors. We recruited a sample of 196 homeless men (101 veterans, 95 non-veterans) from the Omaha, Nebraska metropolitan area. Structured interviews were conducted by research staff. The results showed that the two groups were similar in most respects, though there were several notable differences. Homeless veterans were found to be older and more educated than non-veterans, more likely to have married, and reported having fewer non-adult children. Multivariable models controlling for age further showed that veterans reported a higher number of medical problems and were more likely to report being diagnosed with major depression or PTSD than non-veterans. Comparison with previous studies suggests changes in certain characteristics of homeless veterans over the past few decades that may reflect the growing proportion of veterans from the all-volunteer force, initiated after the draft ended in 1975. Findings from this study were consistent with previous comparative studies suggesting limited changes in recent decades in the characteristics of homeless veterans as compared to non-veterans, although the high prevalence of major depression and PTSD merit special treatment for these disorders.     

The neurobiology of PTSD: implications for nurses

Posttraumatic stress disorder (PTSD) is a disabling and prevalent psychiatric disorder. Researchers and scientists have developed a neurobiological basis, which provides a framework for understanding the complexities of PTSD, for many symtoms of the disorder. The estimated lifetime prevalence of PTSD among adult Americans is 7.8%, with women twice as likely as men to have PTSD. Onset of symptoms can occur years after exposure to trauma, and the duration of the illness can last a lifetime. Patients with PTSD often encounter multiple psychosocial problems that result from the symptoms they experience, and their distorted perceptions can affect relationships within the family and the workplace. Nurses in various roles (e.g., educator, therapist, prescriber, case manager, staff nurse) may encounter individuals with PTSD. The nursing profession has traditionally sought to explain sophisticated language to patients in understandable terms, and nurses serve in encouraging, supporting, and evaluating roles, all of which will be increasingly important as science and technology discover more information about the neurobiological basis for mental illnesses.

Posttraumatic stress disorder and occupational performance: building resilience and fostering occupational adaptation

Resilience and vulnerability refer to an individual's capacity to persevere in the face of adversity. Resiliency and vulnerability are distinctive personal characteristics influenced by environmental factors such as socio-cultural and institutional contexts. Resiliency and vulnerability are not absolute; they are psychosocial constructs of a phenomenological continuum. Hence, a resilient individual is not invincible to all life events but has the capacity to endure in most circumstances. Clients who sustain traumatic injuries or witness traumatic events have a greater vulnerability to stress disorders like posttraumatic stress disorder (PTSD). Occupational therapy practitioners should be cognizant of a client's resilient and adaptive capacities when providing services to a client who has endured a traumatic event. This paper explores resilience theory and its application to occupational therapy practice.
