Interventions for posttraumatic stress disorder: a review of the evidence base

Given high rates of trauma exposure in South Africa, mental health practitioners often need to deliver interventions to trauma survivors. While there have been few local trauma intervention studies, there is an extensive international evidence base that provides a rich resource on which to draw. This article reviews evidence-based treatments for posttraumatic stress disorder and complex posttraumatic stress disorder. The current weight of evidence supports the use of trauma-focused cognitive behavioural therapy approaches in the treatment of posttraumatic stress disorder and the use of multimodal, phase-based interventions to treat complex posttraumatic stress disorder. There is also a long-standing, though less extensive, evidence base for psychodynamic therapy in the treatment of these conditions, as well as a number of emerging treatment approaches that require further study. While there are some limitations to transferring these approaches to the South African context, the current evidence base provides valuable guidelines for local practitioners seeking to develop their competencies in treating posttraumatic stress disorder and more complex trauma-based presentations.

Rethinking Compassion Fatigue Through the Lens of Professional Identity: The Case of Child-Protection Workers

Compassion fatigue is currently the dominant model in work-related stress studies that explain the consequences of caring for others on child-protection workers. Based on a deterministic approach, this model excludes the role of cognition a priori and a posteriori in the understanding of the impact of caregiving or providing social support. By integrating the notion of professional identity, this article adds a subjective perspective to the compassion fatigue model allowing for the consideration of positive outcomes and takes into account the influence of stress caused by accountability. Mainly, it is argued that meanings derived from identity and given to situations may protect or accelerate the development of compassion fatigue or compassion satisfaction. To arrive at this proposition, the notions of compassion fatigue and identity theory are first reviewed. These concepts are then articulated around four work-related stressors specific to child-protection work. In light of this exercise, it is argued that professional identity serves as a subjective interpretative framework that guides the understanding of work-related situations. Therefore, compassion fatigue is not only a simple reaction to external stimuli. It is influenced by meanings given to the situation. Furthermore, professional identity modulates the impact of compassion fatigue on psychological well-being. Practice, policy, and research implications in light of these findings are also discussed.

Training in evidence-based practice

Controversy surrounds the concept of EBP. Many individuals question whether research is capable of guiding decisions about diagnosis and treatment, or whether it simply gives oversimplified answers to highly complex questions about human behavior. These concerns aside, it is hard to envision a future in which consumers and payers do not demand that the health professions ground their interventions in an evidence base. It is sobering to recognize that training in EBP has been far from the norm in the various behavioral health disciplines. This is just one aspect of a much larger crisis in behavioral health workforce education. Graduate and residency programs have not kept pace with many of the changes in behavioral health care delivery over the past decade. The field continues to use continuing education strategies that are ineffective, and little training is offered to the paraprofessional and bachelor-prepared staff members who comprise a large segment of the workforce in public sector and inpatient settings. Broad strategies are needed to overcome the lethargy in behavioral health education and training programs to make them more relevant to contemporary clinical practice. Incorporating evidence-based approaches to treatment is one critical element of needed reforms. General medicine has laid a foundation that can be built on for teaching the process of EBP. Psychiatry and psychology have taken the lead in identifying those interventions to be taught that are evidence-based or empirically supported. Research on continuing education and adult learning illuminates the educational strategies that are likely effective in teaching evidence-based interventions and an evidence-based process of care. Additionally, the research on changing provider behavior shows the importance of ensuring practice environments that support and reinforce, rather than thwart, the practice of evidence-based treatment. There are many resources to draw on but the task facing educators is substantial.

Empirically supported psychological interventions: controversies and evidence

Efforts to increase the practice of evidence-based psychotherapy in the United States have led to the formation of task forces to define, identify, and disseminate information about empirically supported psychological interventions. The work of several such task forces and other groups reviewing empirically supported treatments (ESTs) in the United States, United Kingdom, and elsewhere is summarized here, along with the lists of treatments that have been identified as ESTs. Also reviewed is the controversy surrounding EST identification and dissemination, including concerns abou research methodology, external validity, and utility of EST research, as well as the reliability and transparency of the EST review process.
