Objective: The present study tested the hypothesis that social problem solving (SPS) served to mediate the relationship between preceived stress and noncardiac chest pain (NCCP). Design: Adults undergoing stress myocardial perfusion imaging (MPI) to determine the presence of underlying cardiovascular disease related to the experience of chest pain were recruited prior to stress testing to complete a series of self-report inventories. Main Outcome Measures: MPI results were used to identify individuals with NCCP (N = 166; 91 men, 75 women; mean age = 53.92 years, SD = 11.98). Measures included perceived stress, SPS, and chest pain frequency and intensity. Results: In direct tests of the mediational effects of SPS, it was found that two problem-solving dimensions, negative problem orientation and rational problem solving, each served as significant mediators of the effects of stress on both NCCP intensity and frequency. Conclusion: These results support a mediational analysis of NCCP that includes stress and SPS. As such, it identifies SPS as a potentially important clinical target to consider when developing future psychosocial-based therapy protocols for treating individuals with NCCP.

This article examines countertransference in the assessment and treatment of recovery from traumatic incidents of adulthood, with specific focus on victims of violent crime. It reviews Freud's impediment theory, with particular attention to implications concerning empathic strain and vicarious traumatization. It introduces Wilson and Lindy's Type I Countertransference (avoidance), Type II Countertransference (overidentification), and their respective manifestations. It then proposes a Type III Countertransference (communicative) that applies a more totalistic perspective that utilizes concepts of splitting, projection, projective identification, and intersubjectivity. It differentiates between countertransference orientations to trauma that are content-based or processed-based as well as those that may be figure or ground. Finally, it presents some common countertransference reactions and roles that become enacted and therefore have treatment implications, examines the interaction between therapeutic and real relationships as contributors to those scenarios, and presents case examples.

The following paper critically examines invalidation's role in trauma, drawing extensively on the work of Bromberg who is one of its most influential proponents. Although Bromberg correctly identifies invalidation as a necessary condition, his central argument is weakened by portraying personal identity as an illusion concealing the existence of multiple selves. Against his view, I suggest that its causal relevance is most clearly demonstrated in terms of its impact on agentic and/or core beliefs. This hypothesis is consistent with the perspectives of nonrelational psychoanalytic theorists and enjoys robust empirical support. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Reports an error in "Treating traumatized OEF/OIF veterans: How does trauma treatment affect the clinician" by Sarah C. Voss Horrell, Dana R. Holohan, Lea M. Didion and G. Todd Vance (Professional Psychology: Research and Practice, 2011[Feb], Vol 42[1], 79-86). The word “While” was erroneously inserted in the first sentence of the “Clinician Factors” section. The corrected sentence is provided in the erratum. (The following abstract of the original article appeared in record 2011-04544-011.) The authors of this article describe the rewards and challenges for clinicians treating veterans who have served in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Issues of vicarious trauma, secondary traumatic stress, compassion fatigue, and burnout are defined and reviewed, as are compassion satisfaction and posttraumatic growth. Patient, clinician, and organizational characteristics that are likely to affect clinicians working with this clinical population are discussed. Patient factors that may increase strain on clinicians are discussed such as age, likelihood of redeployment, comorbid conditions, attendance issues, and elevated risk for suicide and aggression. Clinician factors, such as theoretical orientation, training, supervision, military affiliation, personal trauma history, spirituality, social support, and self-care, are also discussed as possible risk and protective factors for vicarious trauma and burnout. Organizational influences, such as caseload size and diversity, clinician control and autonomy, use of evidence-based practices, availability of resources, rural isolation, and the philosophy of the clinic, are further discussed. Recommendations for ameliorating risks are discussed relative to each area and include allowing clinicians to plan their own appointments so as to balance their caseload of OEF/OIF veterans, attending to self-care practices, and having a supportive team with thorough training in evidence-based practices. Future empirical research is needed on risk and resiliency factors for clinicians working with traumatized OEF/OIF veterans given that this population is likely to grow.

Interest in meaning and meaning making in the context of stressful life events continues to grow, but research is hampered by conceptual and methodological limitations. Drawing on current theories, the author first presents an integrated model of meaning making. This model distinguishes between the constructs of global and situational meaning and between “meaning-making efforts” and “meaning made,” and it elaborates subconstructs within these constructs. Using this model, the author reviews the empirical research regarding meaning in the context of adjustment to stressful events, outlining what has been established to date and evaluating the strengths and weaknesses of current empirical work. Results suggest that theory on meaning and meaning making has developed apace, but empirical research has failed to keep up with these developments, creating a significant gap between the rich but abstract theories and empirical tests of them. Given current empirical findings, some aspects of the meaning-making model appear to be well supported but others are not, and the quality of meaning-making efforts and meanings made may be at least as important as their quantity. This article concludes with specific suggestions for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

While there is a growing literature on the impact of trauma on children, there has been relatively little attention to the needs of their caregivers, who are themselves at risk for elevated levels of stress. The current article draws from the broader literature on parenting under stress and the literature on interventions with parents of sexually abused children to outline the need for interventions for caregivers of multiply traumatized children. It reviews components of an intervention model derived from the literature on general parenting interventions as well as the growing literature on trauma treatment.
