ABSTRACT
Objective: Peritraumatic reactions feature prominently among the main predictors for development of posttraumatic stress disorder (PTSD). Peritraumatic tonic immobility (PTI), a less investigated but equally important type of peritraumatic response, has been recently attracting the attention of researchers and clinicians for its close association with traumatic reactions and PTSD. Our objective was to investigate the role of PTI, peritraumatic panic, and dissociation as predictors of PTSD symptoms in a cohort of police recruits (n=132). Methods: Participants were asked to complete the following questionnaires during academy training and after the first year of work: Posttraumatic Stress Disorder Checklist - Civilian Version (PCL-C), Physical Reactions Subscale (PRS), Peritraumatic Dissociative Experiences Questionnaire (PDEQ), Tonic Immobility Scale (TIS), and Critical Incident History Questionnaire. Results: Employing a zero-inflated negative binomial regression model, we found that each additional point in the TIS was associated with a 9% increment in PCL-C mean scores (RM = 1.09), whereas for PRS, the increment was 7% (RM = 1.07). As the severity of peritraumatic dissociation increased one point in the PDEQ, the chance of having at least one symptom in the PCL-C increased 22% (OR = 1.22). Conclusions: Our findings highlight the need to expand investigation on the incidence and impact of PTI on the mental health of police officers. .

BACKGROUND: Exposure to traumatic events is a necessary but not a sufficient condition for the development of posttraumatic stress disorder (PTSD). Pretrauma, peritrauma and posttrauma factors interact to impact on symptom severity. The aim of the present study is to determine risk factors for PTSD symptoms in Brazilian police officers. METHOD: In a cross-sectional sample of active duty officers (n = 212), participants were asked to complete a socio-demographic questionnaire and self-report scales on affective traits, cumulative critical incident exposure, peritraumatic distress and dissociation, PTSD symptoms, and social support. Hierarchical linear regression analysis was conducted to examine predictors of PTSD symptoms. RESULTS: Variables related to negative affect, job duration, frequency of critical incident exposure, peritraumatic dissociation, and lack of social support remained significant in the final model and explained 55% of the variance in PTSD symptoms. When interaction terms were evaluated, a synergistic effect between negative affect and peritraumatic dissociation was found. CONCLUSIONS: The risk factors found in this study provide clues on how to elaborate primary prevention strategies regarding PTSD symptoms in police officers. Such initiatives may lessen the impact of repeated exposure to traumatic events on police officers over the course of their careers.

INTRODUÇÃO: A exposição a eventos traumáticos é uma condição necessária, porém não única, para o desenvolvimento de transtorno de estresse pós-traumático (TEPT). Fatores individuais pré, peri e pós-trauma exercem impacto sobre a gravidade dos sintomas. O objetivo do presente estudo é determinar os fatores de risco para o desenvolvimento de sintomas de TEPT em policiais brasileiros. MÉTODO: Uma amostra transversal de policiais em atividade (n = 212) foi convidada a responder um questionário sóciodemográfico e escalas autoaplicáveis sobre afeto positivo e negativo, frequência de incidentes críticos, sofrimento e dissociação peritraumáticos, sintomas de TEPT e apoio social. Regressão linear hierárquica foi utilizada para avaliar fatores de risco. RESULTADOS: Afeto negativo, tempo de trabalho, frequência de exposição a eventos traumáticos, dissociação peritraumática e apoio social diminuído permaneceram no modelo final e explicaram 55 por cento das variações dos sintomas de TEPT. Foi observado efeito sinérgico entre dissociação peritraumática e afeto negativo. CONCLUSÃO: Baseados nos achados os autores discutem estratégias de prevenção que visam diminuir o impacto da exposição a eventos traumáticos em policiais ao longo de suas carreiras.

BACKGROUND: To measure the serum lipid composition of a sample of Brazilian police officers with and without PTSD regularly exposed to potentially traumatic situations. METHODS: A cross-sectional survey was conducted with 118 active duty male police officers. Serum concentrations for total cholesterol, LDL-C, HDL-C, and triglycerides were enzymatically determined. Body mass index (BMI) was obtained for each participant. RESULTS: Officers with PTSD exhibited significantly higher serum total cholesterol, LDL-C and triglycerides levels than those without PTSD. Total cholesterol and triglycerides, but not LDL-C, remained associated with PTSD diagnosis after controlling for confounding influences (i.e. socio-demographics, BMI, and tobacco, alcohol and medication use). LIMITATIONS: The sample size was small. A nutritional interview was employed instead of established scales to assess alimentary habits, tobacco or alcohol consumption. A self-report screening tool was used to assess the prevalence of PTSD. CONCLUSIONS: The association between PTSD and abnormal serum lipid profile and a tendency to exhibit higher BMI suggests that individuals with PTSD may be at increased risk for developing metabolic syndrome, a condition that by itself could account for many of the most serious PTSD-related physical health problems.

BACKGROUND: Frequent exposure to traumatic situations put police officers under an increased risk for developing post-traumatic stress disorder (PTSD). The goals of this study were to determine the current prevalence of post-traumatic stress symptoms (PTSS) in Brazilian police officers and to compare groups with and without PTSS in terms of associated morbidity. METHODS: Police officers from an elite unit (n=157) were asked to fill out a socio-demographic questionnaire, the 12-item General Health Questionnaire and the Post-Traumatic Stress Disorder Checklist-Civilian Version. The latter's scores were used to establish the diagnoses of "full PTSD" and of "partial PTSD". RESULTS: Prevalence rates of "full PTSD" and "partial PTSD" were 8.9% and 16%, respectively. Compared with the "no PTSD" group, police officers with "full PTSD" were five times more likely to be divorced (21.6% vs. 4.3%, p=0.008), felt that their physical health was poorer (64.3% vs. 6%, p<0.001), had more medical consultations during the last 12 months [2.00 (+/-1.62) vs. 1.09 (+/-1.42), p=0.03] and reported more often lifetime suicidal ideation (35.7% vs. 5.2%, p=0.002). LIMITATIONS: The sample was relatively small. A screening tool was employed instead of a semi-structured interview. The cross-sectional design is unsuitable for ascertaining cause-effect relations. CONCLUSIONS: PTSD prevalence in our sample was comparable to those reported for North American and Dutch policemen. The presence of "full PTSD" was associated with evidences of considerable morbidity. These findings may contribute to the development of effective policies aimed at the prevention and treatment of PTSD in law enforcement agents.

Objetivo: Traduzir e determinar a equivalência semântica da Peritraumatic Distress Inventory (PDI) para o Português. Métodos: A versão da escala PDI em português foi ralizada em quatro etapas: tradução, retradução, apreciação formal de equivalência semântica e pré-teste na população-alvo de 22 policiais militares. Uma fase adicional incluiu a análise da equivalência semântica por um dos autores da escala original. Resultados: A versão T1 e a retradução B1 obtiveram maiores escores entre ambos os avaliadores, atingindo notas máximas em 13 dos 15 itens. A população-alvo consistiu em 22 policiais militares (17 homens e 5 mulheres) sem queixas psiquiátricas. A média de idade foi de 33,9 (+- 4,63) anos e todos tinham o ensino médio completo. A população-alvo compreendeu todos os itens da PDI em português e o tempo médio de resposta da escala foi de 90 (+- 10,48) segundos. Conclusões: Este trabalho torna disponível em português a PDI, a primeira escala que avalia objetivamente o critério A2 para o diagnóstico do transtorno de estresse pós-traumático. As propriedades psicométricas da PDI em português devem ser estudadas posteriormente.
