Acute stress disorder and defense mechanisms: a study of physical trauma patients admitted to an emergency hospital / Transtorno de estresse agudo e mecanismos de defesa: pesquisa com pacientes que sofreram trauma físico atendidos em um hospital de emergência

Abstract Introduction: Acute stress disorder (ASD) encompasses a set of symptoms that can arise in individuals after exposure to a traumatic event. This study assessed the defense mechanisms used by victims of physical trauma who developed ASD. Method: This was a controlled cross-sectional study of 146 patients who suffered physical trauma and required hospitalization. A structured questionnaire was used to evaluate ASD symptoms based on DSM-5 diagnostic criteria, in addition to the Defense Style Questionnaire (DSQ). Results: Ten participants (6.85%) received a positive diagnosis of ASD, and 136, (93.15%) a negative diagnosis. The majority of the sample consisted of men with median age ranging from 33.50 to 35.50. The most prevalent defense mechanisms among the 10 patients with ASD were cancellation and devaluation, which belong to the neurotic and immature factors, respectively. Positive associations between the presence of symptoms from criterion B of the DSM-5 and defense mechanisms from the DSQ were found. These included the mechanisms of undoing, projection, passive aggression, acting out, autistic fantasy, displacement, and somatization. Conclusion: Patients with ASD employed different defense mechanisms such as undoing and devaluation when compared to patients not diagnosed with ASD. These results mark the importance of early detection of ASD symptoms at a preventative level, thereby creating new possibilities for avoiding exacerbations related to the trauma, which represents an important advance in terms of public health.

Resumo Introdução: O transtorno de estresse agudo (TEA) reúne um conjunto de sintomas que pode surgir nos indivíduos após exposição a um evento traumático. Este estudo verificou a relação entre o estilo defensivo e o desenvolvimento de TEA e seus sintomas em uma amostra de pacientes que sofreram trauma físico. Métodos: Este estudo transversal controlado envolveu 146 pacientes que sofreram trauma físico e necessitaram hospitalização. Um questionário estruturado foi utilizado para avaliar sintomas de TEA, baseado nos critérios diagnósticos do DSM-5, além do Questionário de Estilo Defensivo (Defense Style Questionnaire - DSQ). Resultados: Dez (6,85%) pacientes tiveram diagnóstico positivo para TEA, e 136 (93,15%), diagnóstico negativo. A maioria da amostra foi composta por homens com idade mediana variando de 33,50 a 35,50. Nos 10 pacientes positivos para TEA, destacou-se a maior utilização de mecanismos de defesa de anulação e desvalorização, pertencentes ao fator neurótico e ao fator imaturo, respectivamente. Foram observadas associações positivas entre presença de sintomas de TEA do critério B do DSM-5 e os mecanismos de defesa do DSQ, sobretudo nos mecanismos de anulação, projeção, agressão passiva, acting out, fantasia autística, deslocamento e somatização. Conclusão: Pacientes com TEA utilizaram mais mecanismos de defesa do tipo anulação e desvalorização quando comparados aos pacientes sem diagnóstico de TEA. Ressalta-se a importância da detecção precoce de sintomas de TEA a fim de evitar outros agravos relacionados ao trauma, o que representa uma importante evolução em termos de saúde pública.

Las crisis de angustia en la urgencia y su relación con los factores desencadenantes desde una perspectiva de género / [Acute stress disorder in the emergency, its relationship with trigger factors from a gender perspective].

BACKGROUND: Anxiety disorders and, in particular, acute stress disorder are one of the principal reasons for medical assistance, being the women the ones who frequently consult. AIMS: To describe and analyze, from a perspective of gender, the factors that unleash the consultation of an episode of acute stress disorder in the emergency. MATERIALS AND METHOD: An exploratory descriptive study was performed. A semi-directed interview and a socio-demographic questionnaire were assessed and scales to evaluate anxiety and depression were administered to females that consulted for an acute stress disorder. RESULTS: Sixty nine percent of the patients described the physical discomfort as trigger factor, presenting in the 85

of the cases a degree of major anxiety; associating the family conflicts as the principal cause of distress, followed by violence against women. The situation of distress, in 75

of the cases, did not correspond with an isolated episode. CONCLUSION: The physical symptomatology was the principal cause for consultation of an episode of acute stress disorder in the emergency, being the family conflicts and the violence against women the principal reasons of distress. Therefore, interdisciplinary approach for the assistance of mental disorders in emergency should be taken in consideration.

Psychometric Properties of the Korean Version of Stanford Acute Stress Reaction Questionnaire

The present study aimed to examine the psychometric properties of the Korean version of Stanford Acute Stress Reaction Questionnaire (SASRQ). A Korean version of the SASRQ was produced through forward translation, reconciliation, and back translation. A total of 100 healthy, non-clinical participants were selected through screening and clinical interview, and they each were given a set of questionnaires including SASRQ. Psychometric properties of SASRQ were then examined through statistical analyses. Full-scale and subscales of SASRQ yielded excellent internal consistency (Cronbach's alpha=0.98 and 0.78-0.95, respectively). Test-retest reliability at 2-week intervals was satisfactory, with coefficient r ranging between 0.47 and 0.71. Convergent validity was also demonstrated by strong correlations between SASRQ and other trauma-related questionnaires. Correlation with Social Desirability Scale, however, was not found to be significant; thus evidenced divergent validity. The Korean version of SASRQ appears to be a reliable and valid measurement tool for assessing symptoms of acute stress disorder. Including clinical samples for comparison with controls would be necessary in future studies.

Transtorno de estresse pós-traumático: evolução dos critérios diagnósticos e prevalência / Posttraumatic stress disorder: development of diagnostic criteria and prevalence

O transtorno de estresse pós-traumático (TEPT) se caracteriza por sintomas persistentes de revivência, evitação e entorpecimento, e excitabilidade aumentada, após a exposição a um evento traumático. Estudos epidemiológicos mostram que, entre os transtornos de ansiedade, o TEPT é o terceiro mais prevalente. Desde 1980, quando foi reconhecido como um diagnóstico válido, mudanças conceituais importantes ocorreram. A partir disso, o presente artigo apresenta uma revisão crítica da literatura sobre o desenvolvimento dos critérios diagnósticos do TEPT ao longo das edições do Manual diagnóstico e estatístico dos transtornos mentais (DSM), bem como informações sobre a prevalência do transtorno.

Posttraumatic stress disorder (PTSD) can be characterized by persistent symptoms of reexperience, avoidance and numbing, and increased arousal following exposure to a traumatic event. Epidemiological studies showed that PTSD is the third most prevalent anxiety disorder. Since it's recognition in 1980 as a valid diagnosis, important conceptual changes occurred. This article presents a critical review of the literature regarding development of diagnosis criteria of PTSD in the Diagnostic and statistical manual of mental disorders (DSM) as well as information regarding its prevalence.
