The accuracy of the Clinician-Administered PTSD Scale (CAPS) to identify PTSD cases in victims of urban violence.

As a consequence of the increasing urban violence in Brazil, many cases of posttraumatic stress disorder (PTSD) are now seen in the community and clinical settings. The main aim of this article is to assess the psychometric properties of the Clinician-Administered PTSD Scale (CAPS) to study factors related to the etiology, prognosis, and efficacy of interventions of PTSD in civilian populations. PTSD outpatients from a program of victims of violence and subjects identified in an epidemiological survey conducted in the city of Sao Paulo completed a battery of validated instruments and the CAPS. Instrument reliability and validity were measured. The comparison between the CAPS scores and the Structured Clinical Interview for DSM IV (SCID) interview resulted in the following validity coefficients: sensitivity=90%, specificity=95%, and misclassification rate=7.1%. The area under the receiver operating characteristic (ROC) curve was 0.97. There was a positive correlation between CAPS scores with Beck Depression Inventory (BDI; 0.70) and Beck Anxiety Inventory (BAI; 0.76) scores. The Kappa coefficients were all higher than 0.63 for all CAPS items. The internal consistency for all CAPS items resulted in a Cronbach's alpha coefficient of 0.97. The CAPS showed to be both an accurate and a reliable research instrument to identify PTSD cases in a civilian population.

[Early Trauma Inventory (ETI): cross-cultural adaptation and internal consistency]. / Adaptação transcultural e consistência interna do Early Trauma Inventory (ETI).

Early life stress is a strong predictor of future psychopathology during adulthood. The Early Trauma Inventory (ETI) was developed to detect the presence and impact of traumatic experiences that occurred up to 18 years of age. The ETI was translated and cross-culturally adapted and had its consistency evaluated. Victims of violence that met the inclusion and exclusion criteria were submitted to SCID-I and ETI. Ninety-one patients with post-traumatic stress disorder (PTSD) were included. Cronbach's alpha in the different domains varied from 0.595 to 0.793, and the total score was 0.878. Except for emotional abuse, most of the various domains displayed inter-item correlation rates of 0.51 to 0.99. The adapted version was useful for clinical and research purposes and showed good internal consistency and inter-item correlation. The ETI is a valid instrument with good consistency for evaluating history of childhood and adolescent trauma in adults.

The clinical correlates of reported childhood sexual abuse: an association between age at trauma onset and severity of depression and PTSD in adults.

This study investigated the relationship between the age of -self-reported sexual abuse occurrence and the development of post-traumatic stress disorder and/or depressive symptoms in adulthood. Subjects were evaluated for the presence of post-traumatic stress disorder and/or depressive symptoms as well as for a self-reported history of sexual abuse before the age of 18. Results found that relative risk of having severe post-traumatic stress disorder symptoms was 10 times higher in patients reporting sexual abuse after age 12 than in those reporting sexual abuse before age 12. Relative risk of having severe depressive symptoms was higher for those abused before the age of 12 than for those abused after the age of 12. Findings suggest that the impact of reported sexual abuse at different stages of development may lead to distinct psychiatric symptoms in adulthood.

Adaptação transcultural e consistência interna do Early Trauma Inventory (ETI) / Early Trauma Inventory (ETI): cross-cultural adaptation and internal consistency

As experiências traumáticas precoces são um fator de risco preditivo de problemas psicopatológicos futuros. O Early Trauma Inventory (ETI) é um instrumento que avalia em indivíduos adultos experiências traumáticas ocorridas antes dos 18 anos de idade. Tal instrumento foi traduzido, transculturalmente adaptado e sua consistência interna foi avaliada. Vítimas de violência que preencheram os critérios de inclusão e exclusão foram submetidas a uma entrevista diagnóstica (SCID-I) e ao ETI. Foram incluídos 91 pacientes com o transtorno do estresse pós-traumático (TEPT). O alfa de Cronbach nos diferentes domínios variou de 0,595-0,793, e o escore total foi de 0,878. A maior parte dos itens nos vários domínios, com exceção do abuso emocional, apresentou índices de correlação interitem entre 0,51-0,99. A versão adaptada foi útil tanto na clínica quanto na pesquisa. Apresentou boa consistência interna e na correlação interitem. O ETI é um instrumento válido, com boa consistência para se avaliar a presença de história de traumas precoces em indivíduos adultos.

Aripiprazole in the treatment of posttraumatic stress disorder: an open-label trial / Aripiprazol no tratamento do transtorno de estresse pós-traumático: um ensaio clínico aberto

OBJECTIVE: Post traumatic stress disorder is frequent in the general population (7.8 percent-lifetime-USA). The selective serotonin reuptake inhibitors are the first choice of treatment but result in low remission rates. This study aims to evaluate the effect of aripiprazole monotherapy for the treatment of post traumatic stress disorder. METHOD: Thirty-two patients diagnosed with post traumatic stress disorder were included in a 16-week open label trial of aripiprazole. They were evaluated at baseline, week 8, and 16 with the Clinician-Administered PTSD Scale, Beck Depression Inventory, Beck Anxiety Inventory, Medical Outcome Study Short Form 36, and Social Adjustment Scale. Statistical analysis were performed with an intention-to-treat approach and last observation carried forward. A general linear model for repeated measures comparing the factor with 3 continuous measures from baseline, 8 and 16 weeks was used. A between-subject factor was included RESULTS: Nine patients discontinued the treatment. The mean aripiprazole dose was 9.6 (± 4.3) mg/day. The mean scores at baseline and endpoint for all measures were: Clinician-Administered PTSD Scale - 82.7 (± 23.1) and 51.4 (± 31.4) (F = 11.247, p = 0.001); Beck Anxiety Inventory - 31.7 (± 13.4) and 25.4 (± 18.2) (F = 8.931, p = 0.011); Social Adjustment Scale - 2.4 (± 0.45) and 2.27 (± 0.57) (F = 8.633, p = 0.012); Medical Outcome Study Short Form 36 - 76.6 (± 14.11) and 94.01 (± 25.06) (F = 10.127 p = 0.007); and Beck Depression Inventory - 26.06 (± 11.6) and 21.35 (± 12.6) (F = 1.580, p = 0.042). In all measurements, the differences were statistically significant. CONCLUSIONS: Patients achieved a good response to treatment with aripiprazole, but placebo-controlled studies are needed for more accurate results.

OBJETIVO: O transtorno de estresse pós-traumático é um quadro prevalente (7,8 por cento-lifetime-EUA) que provoca grande prejuízo aos pacientes. Os inibidores seletivos de recaptação de serotonina, medicação de primeira escolha para o tratamento, mostram baixos índices de remissão. Este estudo pretende apresentar uma diferente escolha de medicamento para tratar o transtorno de estresse pós-traumático. MÉTODO: Trinta e dois pacientes com transtorno de estresse pós-traumático receberam aripiprazol por 16 semanas. Foram submetidos na entrada, 8 e 16 semanas às escalas Clinician-Administered PTSD Scale, Beck Depression Inventory, Beck Anxiety Inventory, Medical Outcome Study Short Form 36 e Social Adjustment Scale. Foi usado o modelo linear generalizado para medidas repetidas comparando o fator com as três medidas contínuas nos três pontos de avaliação. Foi feita uma comparação entre sujeitos (grupo tratamento) usando modelo linear generalizado univariado. Usamos a intenção de tratamento e a estratégia da última observação com endpoint (Last Observation Carried Forward). RESULTADOS: Nove pacientes descontinuaram antes da segunda avaliação. A dose média foi 9,6 (± 4,3) mg/dia. As medidas na entrada e no final do tratamento foram: Clinician-Administered PTSD Scale - 82,7 (± 23,1) e 51,4 (± 31,4) (F = 11,247, p = 0,001); Beck Anxiety Inventory - 31,7 (± 13,4) e 25,4 (± 18,2) (F = 8,931, p = 0,011); Social Adjustment Scale - 2,4 (± 0,45) e 2,27 (± 0,57) (F = 8,633, p = 0,012); Medical Outcome Study Short Form 36 - 76,6 (± 14,11) e 94,01 (± 25,06) (F = 10,127 p = 0,007); e Beck Depression Inventory - 26,06 (± 11,6) e 21,35 (± 12,6) (F = 1,580, p = 0,042). Em todas as medidas, as diferenças foram estatisticamente significativas. CONCLUSÕES: O aripiprazol alcançou uma boa resposta em pacientes com transtorno de estresse pós-traumático, mas para resultados mais acurados ainda são necessários estudos controlados com placebo.

[Psychoneuroendocrinology of posttraumatic stress disorder]. / Psiconeuroendocrinologia do transtorno de estresse pós-traumático.

OBJECTIVE: To review the literature on neurobiological findings related to hypothalamic-pituitary-adrenal axis dysfunctions associated with posttraumatic stress disorder. METHOD: The relevant scientific findings were described according to the date of publication and the characteristics of the studies: preclinical studies, studies on early life violence as a risk factor, and clinical findings related to patients diagnosed with posttraumatic stress disorder. RESULTS: A rich literature on hypothalamic-pituitary-adrenal axis dysfunctions and posttraumatic stress disorder was found. Neurobiological findings showed that posttraumatic stress disorder is associated with hypothalamic-pituitary-adrenal axis dysfunctions and other brain-related structures: prefrontal cortex, hippocampus, and amygdala. Posttraumatic stress disorder patients have low plasma levels of cortisol and present increased responsivity of glucocorticoid receptors, suggesting that the inhibition of negative feedback plays a significant role in the disorder pathology. Preclinical studies using animal models of maternal deprivation showed that depending on the moment the trauma occurred during the development, different hypothalamic-pituitary-adrenal axis dysfunctions were produced. Clinical studies showed that early life stress is related to the development of psychopathologies during adulthood. CONCLUSIONS: There is robust evidence of hypothalamic-pituitary-adrenal axis dysfunctions related to posttraumatic stress disorder, and the mechanisms underlying this association are being better understood.

Psiconeuroendocrinologia do transtorno de estresse pós-traumático / Psychoneuroendocrinology of posttraumatic stress disorder

OBJETIVO: Os autores realizaram uma revisão tradicional da literatura sobre os achados neurobiológicos das disfunções do eixo hipotálamo-pituitária-adrenal associados ao transtorno de estresse pós-traumático. MÉTODO: Os achados científicos relevantes foram descritos de acordo com a ordem cronológica de publicação e as características dos estudos, se eram pré-clínicos, relacio-nados à violência precoce como fator de risco e, finalmente, achados clínicos em pacientes portadores de transtorno de estresse pós-traumático. RESULTADOS: Foi encontrada uma literatura rica de achados a respeito de disfunções do eixo hipotálamo-pituitária-adrenal e transtorno de estresse pós-traumático. Os achados mostraram que o transtorno de estresse pós-traumático está associado a disfunções deste eixo e de estruturas cerebrais como o córtex pré-frontal, hipocampo e amídala. Os pacientes com transtorno de estresse pós-traumático apresentam um aumento da responsividade dos receptores de glicocorticóides, sugerindo que a inibição do feedback negativo tem um papel importante na fisiopatologia do quadro. Estudos pré-clínicos com modelos animais de deprivação maternal evidenciaram que, dependendo de quando o trauma ocorre, a disfunção do eixo será diferente. Os estudos clínicos mostram que o estresse precoce está relacionado ao desenvolvimento de psicopatologia durante a vida adulta. CONCLUSÕES: As disfunções do eixo hipotálamo-pituitária-adrenal relacionadas ao transtorno de estresse pós-traumático são evidências robustas e os mecanismos subjacentes a ele são cada vez mais compreendidos.
