Peritraumatic Dissociation Partially Mediates the Influence of Lifetime Trauma Exposure on Prospective PTSD Symptoms.

Higher lifetime trauma exposure and increased peritraumatic dissociation (PD) are well-known predictors of Post-Traumatic Stress Disorder (PTSD) symptoms following new trauma (prospective PTSD symptoms). The interplay between those factors, however, is not well established. In this study, we aimed to assess whether PD mediates the influence of lifetime trauma exposure on prospective PTSD symptoms. A total of 387 adults visiting five emergency departments who had experienced a traumatic event within 72 hours completed baseline assessments on lifetime trauma exposure count and PD. PTSD symptoms were assessed 1 month later. Structural equation modeling was used to examine the mediation effect of PD in the relationship between lifetime trauma exposure count and 1-month PTSD symptoms. We found that PD mediated the association between lifetime trauma exposure count and 1-month PTSD symptoms, even after accounting for some confounders. However, the mediation was partial, accounting for 17.9% of the lifetime trauma exposure count's total effect. While this finding is significant, it also suggests that additional mechanisms beyond PD play a role in explaining the influence of higher lifetime trauma exposure on prospective PTSD symptoms. These findings provide valuable insights into the complex dynamics of PTSD development and call for further research to explore complementary factors and preventive strategies.

[Proposal to address the mental health problems detected after the February 27, 2010 earthquake]. / Propuesta para abordar los problemas de salud mental detectados en el proceso diagnóstico de la Delegación Presidencial para la reconstrucción tras el terremoto del 27 de febrero de 2010.

One of the most important topics mentioned by people from places affected by the February 27th, 2010 earthquake to the Presidential Delegation for the Reconstruction, was the urgent need of mental health care. Given the enormous individual and social burden of mental health sequelae after disasters, its treatment becomes a critical issue. In this article, we propose several actions to be implemented in Chile in the context of the process of recovery and reconstruction, including optimization of social communication and media response to disasters; designing and deployment of a national strategy for volunteer service; training of primary care staff in screening and initial management of post-traumatic stress reactions; and training, continuous education and clinical supervision of a critical number of therapists in evidence-based therapies for conditions specifically related to stress.

[Management of psychological trauma in primary care]. / Trauma psicológico en la atención primaria: orientaciones de manejo.

Exposure to traumatic events is frequent in the general population and psychiatric sequelae such as post-traumatic stress disorders are common. The symptoms of psychiatric sequelae after trauma are vague, with multiple psychological and physical symptoms, which can confuse the health care professional. This paper seeks to facilitate the work in primary care, providing practical information about the diagnosis, initial management and referral of patients who have suffered traumatic experiences. Some early interventions and treatments are suggested.

Effects of mindfulness-based stress reduction on psychological distress in health workers: A three-arm parallel randomized controlled trial.

Mindfulness-based Stress Reduction (MBSR) has shown good efficacy for improving wellbeing in employees experiencing occupational stress. However, comparisons with other interventions, longer-term follow-up, and data from varying sociocultural contexts are lacking. This three-arm, parallel randomised controlled trial (RCT) examined the effects of MBSR on psychological distress in non-physician health workers in direct contact with patients. 105 participants were randomly allocated to either: (1) MBSR (N = 35), (2) Stress Management Course (SMC; N = 34) or (3) wait-list (N = 36). Participants and those assessing outcomes were blinded to group assignment. Participants completed questionnaires pre- and post-intervention and four months after the intervention. Psychological distress was measured using the General Health Questionnaire (GHQ-12) and Outcome Questionnaire (OQ-45). Secondary outcomes included perceived stress, job satisfaction, mindfulness skills and changes in salivary cortisol. 77 participants completed measures post-intervention and 52 at 4-month follow-up. MBSR showed a post-intervention effect in reducing GHQ-12 (ß = -0.80 [SE = 1.58] p < 0.01) and OQ-45 (ß = -0.72, [SE = 5.87] p < 0.05) psychological distress, compared to SMC and in reducing GHQ-12 (ß = -1.30 [SE = 1.38] p < 0.001) and OQ-45 (ß = -0.71, [SE = 5.58] p < 0.01) psychological distress compared to wait-list condition. In our secondary outcome, only MBSR was associated with a decrease in the cortisol awaking response by 23% (p < 0.05). At follow-up, only effects of MBSR on the psychological distress 'social role' subscale (ß = -0.76 [SE = 1.31] p < 0.05) remained significant, compared to SMC. In conclusion, MBSR appears useful in reducing short-term psychological distress in healthcare workers, but these effects were not maintained at follow-up. Trial registration: ISRCTN12039804.

Journal club experience in a postgraduate psychiatry program in Chile.

OBJECTIVE: Literature about journal clubs in postgraduate psychiatry programs is scarce, and there is no reference to residents' preferences. METHODS: Residents were asked to respond to a survey about their general satisfaction with the current journal club format and paper preferences, according to subject, scope, and type. RESULTS: Residents' general satisfaction was high. Residents preferred clinically relevant meta-analyses and randomized controlled trials about mood and psychotic disorders, neuroscience, and biological therapies. CONCLUSION: There is a trend to prefer articles related to biological aspects of psychiatry, centered in evidence-based medicine methodology. An effort should be made to broaden the scope of selection of papers, incorporating, for instance, humanistic views, psychotherapy, and other methodologies.

[Psychological support for disaster victims: an evidence-based care model]. / Apoyo psicológico en desastres: Propuesta de un modelo de atención basado en revisiones sistemáticas y metaanálisis.

A search for meta analyses and systematic reviews on psychological support to disaster victims was carried out to devise a local support model. Based on 36 meta analyses and systematic reviews, the support should be carried out in five echelon levels: diffusion, social support, general medical care, general psychiatric care and psychiatric care carried out by experts. Only victims with well-established formal psychiatric disorders should receive psychotherapy or psychotropic medication. The rest should only receive psychological first aid. According to the best evidence available, a model for psychological care is proposed.
