Emotional processing interventions for trauma and psychological conflicts are underutilized. Lack of adequate training in emotional processing techniques and therapists' lack of confidence in utilizing such interventions are barriers to implementation. We developed and tested an experiential training to improve trainees' performance in a set of transtheoretical emotional processing skills: eliciting patient disclosure of difficult experiences, responding to defenses against disclosure, and eliciting adaptive emotions. Mental health trainees ( N = 102) were randomized to experiential or standard training, both of which presented a 1-hr individual session administered remotely. Before and after training and at 5-week follow-up, trainees were videorecorded as they responded to videos of challenging therapy situations, and responses were coded for demonstrated skill. Trainees also completed measures of therapeutic self-efficacy, anxiety, and depression at baseline and follow-up. Repeated-measures analysis of variance indicated all three skills increased from pre- to posttraining for both conditions, which were maintained at follow-up. Importantly, experiential training led to greater improvements than standard training in the skills of eliciting disclosure (η² = .05, p = .03), responding to defenses (η² = .04, p = .05), and encouraging adaptive emotions (η² = .23, p < .001) at posttraining, and the training benefits for eliciting disclosure were maintained at follow-up. Both conditions led to improved self-efficacy. Trainees' anxiety decreased in the standard training, but not in the experiential. One session of experiential training improved trainees' emotional processing therapy skills more than didactic training, although more training and practice likely are needed to yield longer lasting skills.

Background: Psychological war trauma among displaced refugees is an established risk factor for mental health disorders, especially post-traumatic stress disorder (PTSD). Persons with trauma-induced disorders have heightened neuroplastic restructuring of limbic brain circuits (e.g., amygdala and hippocampus), which are critical factors in the pathophysiology of PTSD. Civilians in war are exposed to both psychological trauma and environmental hazards, such as metals. Little is known about the possible mental health impact from such environmental exposures, alone or in combination with trauma. It is of special interest to determine whether war exposures contribute to dysfunctional neuroplasticity; that is, an adverse outcome from sustained stress contributing to mental health disorders. The current study examined Middle Eastern refugees in the United States to determine the relationships among pre-displacement trauma and environmental exposures, brain derived neurotrophic growth factor (BDNF) and nerve growth factor (NGF)-two neurotrophins reported to mediate neuroplasticity responses to stress-related exposures-and mental health., Methods: Middle Eastern refugees (n = 64; 33 men, 31 women) from Syria (n = 40) or Iraq (n = 24) were assessed 1 month after arrival to Michigan, US. Participants were interviewed in Arabic using a semi-structured survey to assess pre-displacement trauma and environmental exposure, PTSD, depression, anxiety, and self-rated mental health. Whole blood was collected, and concentrations of six heavy metals as well as BDNF and NGF levels were determined. Because these two neurotrophins have similar functions in neuroplasticity, we combined them to create a neuroplasticity index. Linear regression tested whether psychosocial trauma, environmental exposures and biomarkers were associated with mental health symptoms., Findings: The neuroplasticity index was associated with PTSD (standardized beta, β = 0.25, p < 0.05), depression (0.26, < 0.05) and anxiety (0.32, < 0.01) after controlling for pre-displacement trauma exposures. In addition, pre-displacement environmental exposure was associated with PTSD (0.28, < 0.05) and anxiety (0.32, < 0.05). Syrian refugees and female gender were associated with higher scores on depression (0.25, < 0.05; 0.30, < 0.05) and anxiety scales (0.35, < 0.01; 0.27, < 0.05), and worse on self-rated mental health (0.32, < 0.05; 0.34, < 0.05). In bivariate analysis, the neuroplasticity index was related to blood lead levels (r = 0.40; p < 0.01)., Conclusions: The current study confirms the adverse effects of war trauma on mental health. Higher levels of biomarkers of neuroplasticity correlated with worse mental health and higher blood lead levels. Higher neurotrophin levels in refugees might indicate dysfunctional neuroplasticity with increased consolidation of adverse war memories in the limbic system. Such a process may contribute to psychiatric symptoms. Further research is needed to clarify the pathobiological mechanisms linking war trauma and environmental exposures to adverse mental health., Competing Interests: The authors have declared that no competing interests exist.
