“…The Brazilian version of the Clinician Administered PTSD Scale (CAPS) was also administered and used as the gold standard for PTSD diagnosis and symptom quantification. 13 For retest purposes, 15 days after first assessment, 14 individuals from the PTSD+ group completed the PSQI-A-BR again (all individuals were invited to take part in the retest stage, however, only 14 were available to return to the center after 15 days). Six months after the intake assessments, the CAPS, PSQI-A, and PSQI-A-BR were administered again to all who had completed treatment.…”

“…The CAPS is a 30-item structured diagnostic interview designed to measure the frequency and intensity of PTSD symptoms and has been validated in Brazilian Portuguese by Pupo et al 9 The symptoms are scored on a 0-4 scale and the total score ranges from 0 to 136. Scores of 45 or greater are considered indicative of a positive PTSD screen.…”

“…5 Urban violence is currently endemic in Brazil; violent events are part of daily life. 9 Exposure to traumatic events in Sã o Paulo and Rio de Janeiro is highly prevalent: nearly 90% of people surveyed in these two cities have faced at least one lifetime traumatic experience. Over 59% of Sã o Paulo residents and 63% in Rio de Janeiro reported a lifetime direct exposure to violence.…”

“…10 Therefore, the development and validation of reliable instruments for identification of clinically significant sleep disturbances related to PTSD and their severity in Brazilian samples is of paramount importance. 9 To date, there is no validated instrument in Brazilian Portuguese to evaluate DNBs in trauma-exposed and PTSD patients. Thus, the validation of the Brazilian version of the PSQI-A was undertaken.…”

Objective: Sleep disturbances play a fundamental role in the pathophysiology posttraumatic stress disorder (PTSD), and are not only a secondary feature. The aim of this study was to validate and assess the psychometric properties of the Brazilian version of the Pittsburgh Sleep Quality Index Addendum for PTSD (PSQI-A-BR), a self-report instrument designed to assess the frequency of seven disruptive nocturnal behaviors, in a sample of participants with and without PTSD. Methods: PSQI-A was translated into Brazilian Portuguese and applied to a convenience sample of 190 volunteers, with and without PTSD, who had sought treatment for the consequences of a traumatic event.Results: The PSQI-A-BR displayed satisfactory internal consistency (Cronbach's coefficient of 0.83 between all items) and convergent validity with the Clinician Administered PTSD Scale (CAPS), even when excluding sleep-related items (r = 0.52). Test-retest yielded high agreement in the global PSQI-A-BR, with good stability over time (r = 0.88). A global PSQI-A-BR cutoff score of 7 yielded a sensitivity of 79%, specificity of 64%, and a global score of 7 yielded a positive predictive value of 93% for discriminating participants with PTSD from those without PTSD. Conclusion:The PSQI-A-BR is a valid instrument for PTSD assessment, applicable to both clinical and research settings.

“…To assess the presence of PTSD in patients, we used the ClinicianAdministered PTSD Scale (CAPS) 28 , a 30-item scale that investigates the frequency and intensity of PTSD symptoms and traumatic life experiences. Scores ranged from 0 to 136, with the following classifications: subclinical, 0 to 19; mild, 20 to 39; moderate, 40 to 59; severe, 60 to 79; and extreme, 80 and above.…”

Background: Brain-imaging studies in post-traumatic stress disorder (PTSD) have consistently revealed alterations in brain structure and function and this is correlated to symptomatology. However, few studies have investigated the role of biomarkers in PTSD some specific groups, as police officers. Objective: To evaluate prefrontal and limbic volumes, and cortical thickness of police officers exposed to trauma during work who developed post-traumatic stress disorder, resilient matched controls (without PTSD), and compared to healthy civilians. Methods: Prefrontal and limbic volumes, and cortical thickness of 12 police officers with PTSD, 12 resilient police officers, and 12 healthy civilians who underwent brain MRI were analyzed. Results: Differences in limbic structures volume were not significative after Bonferroni correction. A significant reduction in cortical thickness on right rostral cingulate, right and left middle frontal gyrus, left superior frontal, left lingual, calcarine and cuneus were observed in PTSD group in comparison to controls was observed. Discussion: Although preliminary, our results suggested not only the association between cortical thickness and PTSD, but also indicated that patients and controls have anatomical differences.
