Comorbid depressive symptoms in treatment-seeking PTSD outpatients affect multiple domains of quality of life.

Purpose: No study has examined the impact of the comorbid Axis I conditions on the quality of life (QoL) of patients with a primary diagnosis of PTSD. Our goal was to investigate the influence of comorbid disorders on the QoL of treatment-seeking outpatients with PTSD.

Methods: The diagnoses of PTSD and of the comorbid disorders were established using the SCID-I.

Posttraumatic stress disorder in parents of children with chronic illnesses: a meta-analysis.

Objective: To estimate PTSD prevalence in parents of children with chronic illnesses or undergoing invasive procedures, and its association with higher risk of PTSD among parents.

Methods: Sixteen studies reporting prevalence of PTSD in parents of children with chronic illnesses were identified through a systematic review in Pubmed, Web of Science, Pilots and PsycINFO databases.

Main Outcome Measures: Pooled current PTSD prevalence was calculated for parents from these studies.

The increasing internationalization of mainstream posttraumatic stress disorder research: a bibliometric study.

The aim of this study was to quantify changes in the national contributions to research related to posttraumatic stress disorder (PTSD) from 1983 through 2002. Using the Web of Science database (Thomson Scientific, Philadelphia, PA), we classified articles according to the year of publication and the country of the authors. The number of publishing countries increased from 7 between 1983 and 1987 to 39 between 1998 and 2002.

A comparison of publication trends on avoidant personality disorder and social phobia.

The objective of this study was to ascertain the number of articles published per annum on the topics of avoidant personality disorder (APD) and social phobia (SP) in the period from 1973 to 2001. We hypothesized that while annual publication rates on SP would exhibit a sound growth, the number of scientific articles on APD published per annum would present a stagnant or declining trend. We performed a comprehensive literature review on APD and SP using the three largest existing databases for medical and psychological journals: MEDLINE, PsycINFO, and Web of Science.

The cross-cultural adaptation to Portuguese of the Trauma History Questionnaire to identify traumatic experiences.

Background: Despite the high prevalence of exposure to traumatic events in Brazil, there are few studies on trauma and post-traumatic stress disorder. This paper presents the cross-cultural adaptation to Portuguese of the Trauma History Questionnaire.

Methods: Two translations and their respective back-translations were made, as well as the evaluation of the semantic equivalence, the preparation of the synthesis version, the pre-testing in the target population and the definition of the final version.

[The cross-cultural adaptation to Portuguese of the Dissociative Experiences Scale for screening and quantifying dissociative phenomena].

Objective: This paper presents the cross-cultural adaptation to Portuguese of the Dissociative Experiences Scale, the worldwide most employed questionnaire for screening and quantifying dissociative phenomena.

Methods: Two translations and their respective back-translations were performed, as well as the evaluation of the semantic equivalence, the preparation of the synthetic version, the pre-testing on the target population, the definition of the final version and a second pre-testing on the target population.

Results: A high level of semantic equivalence between the original instrument and the two pairs of translations and back-translations was observed regarding the referential and general meanings.
