Recent research has demonstrated that first responders may report posttraumatic growth (PTG), positive psychological changes that arise in the aftermath of a trauma. Less is known regarding the perception of PTG among 9-1-1 telecommunicators, a group of first responders exposed to a high degree of lifetime trauma, including duty-related trauma as well as early and non-duty-related trauma. Moreover, the impact of childhood trauma on the processes involved in the perception of growth is less clear. While some distress is needed to facilitate processes that lead to the perception of PTG, it has been suggested that positive associations between PTG and pathology reflect avoidant coping or represent an illusory component of PTG. Structural equation models were used to examine early trauma exposure, coping, and pathology in predicting PTG among 9-1-1 telecommunicators ( N = 788). In separate models using active and avoidant forms of coping, childhood trauma exposure had an indirect effect on PTG through coping. In a model considering both forms of coping, childhood trauma had an indirect effect on PTG through psychopathology, but not through coping. The results show that early trauma exposure leads to the perception of growth through pathways indicative of both adaptive and maladaptive coping processes.

This chapter examines current findings relating to the molecular neuropharmacology of posttraumatic stress disorder (PTSD). Studies consistently show that neurochemical alterations after trauma exposure are associated with the development of PTSD and reflect in part stress sensitization in PTSD. We also review neuroendocrine, neurotransmitter, neuropeptide, and related molecular features that reflect preexisting vulnerability factors for the development of PTSD. In this chapter, we provide an overview of recent neuroendocrine findings mainly with regard to the influence of the hypothalamic-pituitary-axis. We also review recent neurochemical findings including the influence of different neurotransmitters such as catecholamines, serotonin, amino acids, neuropeptides, neurotrophins, and lipids. We incorporate these new and established neurobiological findings into a proposed integrative model of the neurobiology of PTSD.

This article presents a narrative case study of a client with a history of multiple traumas and severe symptomatology, coupled with an ongoing recovery process. A hermeneutical–phenomenological approach was used to analyze two interviews with the participant over a period of 1 year, following a trauma treatment program. Her husband’s suicide in between the two interviews allowed for an exploration of the possible effects of new trauma exposure on the process of recovery. Analysis of the data revealed how the participant’s early trauma experiences had resulted in escalating symptomatology. Through her relationship with her husband, she gradually became ready to engage in therapy in a way that allowed her to benefit from it. Her husband’s suicide forced her to reconsider her own part in her recovery, resulting in a strengthened feeling of inner security and self-efficacy parallel to what is seen in posttraumatic growth. The results contribute our understanding of individual processes of change and recovery, including processes of growth following cumulative trauma. Plausible mechanisms for growth in the present case was the ability to recognize and tolerate feelings, making sense of one’s own reactions, as well as a sense of control and trust in available resources.
