The top-100 cited articles on post-traumatic stress disorder: a historical bibliometric analysis. PSYCHOL HEALTH MED 2024; 29:453-472. [PMID: 36398923 DOI: 10.1080/13548506.2022.2147555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 10/31/2022] [Accepted: 11/08/2022] [Indexed: 11/19/2022]
Abstract
This is a bibliometric analysis of the most-cited articles on post-traumatic stress disorder (PTSD) with the objective of identifying citation patterns for researchers, journals, centers, periods, topics, and nations. A search was conducted in Thomson Reuters' WoS Core Collection employing the expression TI = (posttraumatic stress disorder OR post-traumatic stress disorder OR PTSD). The 100 most-cited articles were downloaded, and the relevant data were extracted and analyzed. These studies had a total of 69,649 citations, ranging from a minimum of 360 to a maximum of 6029 citations, with an average of 696.49, a standard deviation of 720.92, mode of 369, and a median of 512. Eighty-eight percent of the most-cited articles on PTSD originated from the USA, with just six cities accounting for 52% of the publications and the Boston area alone responsible for almost one-fifth of the total output. The universities of Yale and Harvard headed the ranking of institutions with larger numbers of highly-cited articles. Female researchers represented 42.3% of all authors, 51% of the first authors, and 48% of the corresponding authors. The proportion of M.D. authors decreased significantly between the 1980-1999 (42%) and the 2000-2019 (27.2%) periods while that of Ph.D. authors increased from 44% to 57.4%. The most studied population was military veterans (28%). Female victims of sexual or physical violence, traumatized children, and adult survivors of childhood abuse were assessed in only 6-7% of the most-cited publications. Ten clinical trials evaluated psychological interventions but only three investigated pharmacotherapy. We concluded that influential research on PTSD remains centralized in the USA. A balanced gender representation in publications was found. There was a heavy reliance on combat veterans as the study population. Few highly-cited studies on the pharmacotherapy for PTSD were identified. Focused efforts are needed to address these challenges.

Machine learning applied to fMRI patterns of brain activation in response to mutilation pictures predicts PTSD symptoms. BMC Psychiatry 2023; 23:719. [PMID: 37798693 PMCID: PMC10552290 DOI: 10.1186/s12888-023-05220-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Accepted: 09/25/2023] [Indexed: 10/07/2023] Open
Abstract
BACKGROUND The present study aimed to apply multivariate pattern recognition methods to predict posttraumatic stress symptoms from whole-brain activation patterns during two contexts where the aversiveness of unpleasant pictures was manipulated by the presence or absence of safety cues. METHODS Trauma-exposed participants were presented with neutral and mutilation pictures during functional magnetic resonance imaging (fMRI) collection. Before the presentation of pictures, a text informed the subjects that the pictures were fictitious ("safe context") or real-life scenes ("real context"). We trained machine learning regression models (Gaussian process regression (GPR)) to predict PTSD symptoms in real and safe contexts. RESULTS The GPR model could predict PTSD symptoms from brain responses to mutilation pictures in the real context but not in the safe context. The brain regions with the highest contribution to the model were the occipito-parietal regions, including the superior parietal gyrus, inferior parietal gyrus, and supramarginal gyrus. Additional analysis showed that GPR regression models accurately predicted clusters of PTSD symptoms, nominal intrusion, avoidance, and alterations in cognition. As expected, we obtained very similar results as those obtained in a model predicting PTSD total symptoms. CONCLUSION This study is the first to show that machine learning applied to fMRI data collected in an aversive context can predict not only PTSD total symptoms but also clusters of PTSD symptoms in a more aversive context. Furthermore, this approach was able to identify potential biomarkers for PTSD, especially in occipitoparietal regions.

Abstract
BACKGROUND The goal of the present study was to investigate the association between PTSD and the onset of hypertension in previously normotensive individuals in a population living in the stressful environment of the urban slums while controlling for risk factors for cardiovascular disease (CVD). METHODS Participants were 320 normotensive individuals who lived in slums and were attending a family doctor program. Measurements included a questionnaire covering sociodemographic characteristics, clinical status and life habits, the Posttraumatic Stress Disorder Checklist - Civilian Version, and the Beck Depression Inventory. Incident hypertension was defined as the first occurrence at the follow-up review of the medical records of (1) systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher, (2) the participant started taking antihypertensive medication, or (3) a new diagnosis of hypertension made by a physician. Differences in sociodemographic, clinical, and lifestyle characteristics between hypertensive and non-hypertensive individuals were compared using the χ2 and t tests. Multivariate Cox proportional hazards models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI). RESULTS Six variables - age, educational level, body mass, smoking, diabetes, and PTSD diagnosis - showed a statistically significant (p ≤ 0.20) association with the hypertensive status. In the Cox regression, only PTSD diagnosis was significantly associated with incident hypertension (multivariate HR = 1.94; 95% CI 1.11-3.40). CONCLUSIONS The present findings highlight the importance of considering a diagnostic hypothesis of PTSD in the prevention and treatment of cardiovascular diseases.

The growth and development of research on personality disorders: A bibliometric study. Personal Ment Health 2022; 16:290-299. [PMID: 35182026 DOI: 10.1002/pmh.1540] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 01/19/2022] [Accepted: 02/08/2022] [Indexed: 01/31/2023]
Abstract
This study objective was to investigate publication trends on personality disorders (PD) and to identify patterns of historical development. Publication rates were determined using the Results by Year Timeline feature of PubMed. Time series autoregressive integrated moving average models were used to analyse the publication rates for PDs in quinquennial periods beginning in 1980 and ending in 2019 and to predict the number of publications in the 2024-2029 period. More than 300 articles on antisocial and borderline PD are being published each year, and the models suggest an accelerating growth rate. Approximately 100 articles are being published on average every year on schizotypal PD, and the regression model indicates linear growth in the near future. The mean number of publications per year for obsessive-compulsive, narcissistic and avoidant PDs is in the range of 10-30 with the corresponding models indicating linear growth. Fewer than 10 articles are being published each year on dependent, paranoid, histrionic and schizoid PD, whereas dependent PD shows modest growth and paranoid PD rates tended to stability, histrionic and schizoid PD exhibit declining rates. Personality disorders are a group of conditions with diverse etiological, prognostic, therapeutic, legal, research, social and cultural implications that influence publication rates.

Tonic immobility is associated with posttraumatic stress symptoms in healthcare professionals exposed to COVID-19-related trauma. J Anxiety Disord 2022; 90:102604. [PMID: 35917747 PMCID: PMC9272678 DOI: 10.1016/j.janxdis.2022.102604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 07/01/2022] [Accepted: 07/04/2022] [Indexed: 11/16/2022]
Abstract
The Coronavirus Disease 2019 (COVID-19) pandemic has exposed healthcare workers (HCW) to traumatic situations that might lead to the development of posttraumatic stress disorder (PTSD). An important vulnerability factor for PTSD is the peritraumatic tonic immobility (TI) reaction, an involuntary and reflexive defensive response evoked by an intense and inescapable threat. TI is largely understudied in humans and has not been investigated during trauma related to COVID-19. For HCW, the pandemic context might be experienced as an intense and potentially inescapable threat, i.e., an overwhelming situation. Here, we investigated if TI response occurred during traumatic events related to the pandemic and its association with posttraumatic stress symptoms (PTSS). An online survey of 1001 HCW investigated COVID-19-related traumatic experiences, TI and PTSS. TI was reported for all types of traumatic events, and multivariate regression models revealed that TI was significantly associated with PTSS severity. HCW who reported high TI scores exhibited an increase of 9.08 times the probability of having a probable diagnosis of PTSD. Thus, TI was evoked by pandemic-related traumatic situations and associated with PTSS severity and higher odds of a PTSD diagnosis. Tonic immobility occurrence should be screened, and psychoeducation about its reflexive biological nature should be introduced.

Abstract
ABSTRACT Objective Posttraumatic stress disorder (PTSD) is a highly prevalent and disabling disorder. Even when treated with the first-line intervention, cognitive-behavioral therapy (CBT), 45% of the patients continue suffering from this disorder. Therefore, knowing the factors that could foresee who will respond to CBT would be of great value to the treatment of these patients. Thus, we have systematically reviewed the literature to identify the variables that could predict response to CBT in patients suffering from PTSD. Methods Following the PRISMA 2020 guidelines, we searched the electronic databases ISI Web of Science, Scopus, PsycINFO, MEDLINE, and PTSDpubs until November 2021. Two authors have independently conducted study selection and data extraction. Studies that examined possible predictors of response to therapy on a sample of adults (18-65 years), both genders, with and without comorbidities were considered eligible. The characteristics of the studies were synthesized in a table. The risk of bias was assessed by the Cochrane risk of bias quality assessment tool. Results Twenty-eight studies comprising 15 variables were selected. Among those, eight showed a low risk of bias, 19 showed some concerns, and one showed a high potential risk of bias. The therapeutic relationship was the only variable considered to be a predictor of a good response to therapy. All other variables showed conflicting results. Conclusions The most promising variable, although scientifically weak, is the therapeutic relationship. Additional randomized clinical trials should be conducted to clarify the role of this variable as a predictor of response to CBT in patients with PTSD.

To BDZ or not to BDZ? That is the question! Is there reliable scientific evidence for or against using benzodiazepines in the aftermath of potentially traumatic events for the prevention of PTSD? A systematic review and meta-analysis. J Psychopharmacol 2022; 36:449-459.

Abstract
BACKGROUND Most international guidelines suggest that benzodiazepines (BDZs) may be inefficient or iatrogenic in the aftermath of a potentially traumatic event (PTE). The goal of this study was to assess the strength of the evidence on whether the use of BDZs in the aftermath of a PTE negatively affects the incidence and severity of post-traumatic stress disorder (PTSD). METHODS We systematically scrutinized the ISI Web of Knowledge, MEDLINE, SCOPUS, and PTSDpubs electronic databases in addition to citation searching. We included original studies providing data about the development of PTSD in adults after BDZ administration in the aftermath of a PTE. We screened 387 abstracts and selected eight studies for the qualitative synthesis and seven for the meta-analysis. We performed two separate meta-analyses, one for randomized clinical trials (RCTs) and the other for cohort studies. Heterogeneity between studies was evaluated with Higgins I² statistic and tested using the χ². This study was registered at PROSPERO (number 127170). RESULTS The meta-analysis of the cohort studies showed an increased risk of PTSD in patients who received BDZs compared to those who did not (risk ratio (RR) = 1.53; 95% confidence interval (CI): 1.05-2.23) with a modest heterogeneity among studies (I2 = 41.8, p = 0.143). Regarding the RCTs, the combined measure revealed a tendency toward an increased severity of the PTSD symptoms (standardized mean difference (SMD): 0.24; 95% CI: 0.32-0.79). CONCLUSION The studies reviewed showed a possible harmful effect of BDZs when used immediately after a PTE. However, these conclusions were based on a small number of studies of poor to moderate methodological quality.

Unnecessarily prolonged suffering: a case of missed diagnosis of post-traumatic stress disorder in a teaching hospital. JORNAL BRASILEIRO DE PSIQUIATRIA 2021.

Abstract
ABSTRACT We described a case in which a heavily-traumatized patient had been under psychiatric treatment for seven years (five of them in a university mental health clinic) but was never diagnosed with PTSD and, therefore, did not receive the proper treatment for a very long period. After the correct diagnosis was made and personalized treatment instituted, the patient has shown marked improvement in functionality and wellbeing. The key element in this case, was the adequacy of psychiatric training. Our report suggests that psychiatrists are not being adequately trained to identify traumatic events and to diagnose atypical cases of PTSD. With that in mind, we emphasize that theoretical modules on trauma and trauma-related disorders and practical training in specialized PTSD clinics should be incorporated into the psychiatric residency training programs wherever they may be missing, particularly in countries most impacted by violence. Furthermore, continuing medical education on trauma and PTSD should be provided by medical associations and journals to keep physicians updated on recent progress in the field.

The invisible scars of emotional abuse: a common and highly harmful form of childhood maltreatment. BMC Psychiatry 2021; 21:156. [PMID: 33731084 PMCID: PMC7968325 DOI: 10.1186/s12888-021-03134-0] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2020] [Accepted: 02/12/2021] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Childhood maltreatment (CM) is unfortunately widespread globally and has been linked with an increased risk of a variety of psychiatric disorders in adults, including posttraumatic stress disorder (PTSD). These associations are well established in the literature for some maltreatment forms, such as sexual and physical abuse. However, the effects of emotional maltreatment are much less explored, even though this type figures among the most common forms of childhood maltreatment. Thus, the present study aims to investigate the impact of each type of childhood maltreatment, both individually and conjointly, on revictimization and PTSD symptom severity using a nonclinical college student sample. METHODS Five hundred and two graduate and undergraduate students participated in the study by completing questionnaires assessing lifetime traumatic experiences in general, maltreatment during childhood and PTSD symptoms. Bivariate and multivariate negative binomial regressions were applied to examine the associations among childhood maltreatment, revictimization, and PTSD symptom severity. RESULTS Our results showed that using bivariate models, all types of CM were significantly associated with revictimization and PTSD symptom severity. Multivariate models showed that emotional abuse was the type of maltreatment associated with the highest incidence rates of revictimization and PTSD symptom severity. CONCLUSIONS These data provide additional evidence of the harmful effects of childhood maltreatment and its long-term consequences for individuals' mental health. Notably, the findings highlight the importance of studying the impacts of emotional abuse, which seems to be a highly prevalent, understudied, and chronic form of maltreatment that is as toxic as other maltreatment forms.

Vulnerability and Protective Factors for PTSD and Depression Symptoms Among Healthcare Workers During COVID-19: A Machine Learning Approach. Front Psychiatry 2021; 12:752870. [PMID: 35095589 PMCID: PMC8790177 DOI: 10.3389/fpsyt.2021.752870] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 11/08/2021] [Indexed: 01/06/2023] Open
Abstract
Background: Healthcare workers are at high risk for developing mental health problems during the COVID-19 pandemic. There is an urgent need to identify vulnerability and protective factors related to the severity of psychiatric symptoms among healthcare workers to implement targeted prevention and intervention programs to reduce the mental health burden worldwide during COVID-19. Objective: The present study aimed to apply a machine learning approach to predict depression and PTSD symptoms based on psychometric questions that assessed: (1) the level of stress due to being isolated from one's family; (2) professional recognition before and during the pandemic; and (3) altruistic acceptance of risk during the COVID-19 pandemic among healthcare workers. Methods: A total of 437 healthcare workers who experienced some level of isolation at the time of the pandemic participated in the study. Data were collected using a web survey conducted between June 12, 2020, and September 19, 2020. We trained two regression models to predict PTSD and depression symptoms. Pattern regression analyses consisted of a linear epsilon-insensitive support vector machine (ε-SVM). Predicted and actual clinical scores were compared using Pearson's correlation coefficient (r), the coefficient of determination (r2), and the normalized mean squared error (NMSE) to evaluate the model performance. A permutation test was applied to estimate significance levels. Results: Results were significant using two different cross-validation strategies to significantly decode both PTSD and depression symptoms. For all of the models, the stress due to social isolation and professional recognition were the variables with the greatest contributions to the predictive function. Interestingly, professional recognition had a negative predictive value, indicating an inverse relationship with PTSD and depression symptoms. Conclusions: Our findings emphasize the protective role of professional recognition and the vulnerability role of the level of stress due to social isolation in the severity of posttraumatic stress and depression symptoms. The insights gleaned from the current study will advance efforts in terms of intervention programs and public health messaging.

Abstract
ABSTRACT Objective: Bibliometrics is a group of statistical and mathematical methods employed to measure and analyze the quantity and the quality of scientific articles, books, and other forms of publications. The objective of the present study was to conduct a bibliometric analysis of the Jornal Brasileiro de Psiquiatria (JBP) by listing its 100 most highly cited articles in the scientific literature and identifying their main characteristics in terms of authorship and research topics and design. Methods: The 100 top-cited references in the JBP were identified through a search with Google Scholar. The main author, last author, corresponding author, the total number of authors, gender of the authors, year of publication, research institution, geographic origin, language, and the research design and subject of each reference were recorded and analyzed. Results: A marked increase in the number of citations in the last 15 years, a relatively balanced distribution of publications among the Brazilian states and research centers, absence of gender bias among authors, and a varied range of published topics suggest a good current editorial performance by the JBP. Relative lack of systematic reviews and longitudinal studies, dearth of articles published in the English language, and modest participation of foreign authors were points requiring improvement. Conclusion: The present study suggests that a survey of the 100 most cited articles in the JBP can provide a historical overview of the progress of this journal, as well as highlight the main obstacles, constraints, and challenges faced by its editors and authors.

Abstract
The objective of the study was to investigate whether a diagnosis of posttraumatic stress disorder (PTSD; full or partial) or specific PTSD symptom clusters predicted failure in quitting smoking in a trauma-exposed population. Methods: Participants were 310 smokers who attempted quitting smoking, either successfully (quitters, n = 213) or not (relapsers, n = 97), who lived in slums and were attending a family doctor program. Measurements included a general questionnaire covering sociodemographic characteristics, clinical status and life habits, and the Posttraumatic Stress Disorder Checklist - Civilian Version. Differences in sociodemographic, clinical and lifestyle characteristics between quitters and relapsers were compared using a chi-square test. Because of the small sample size, full and partial PTSD were collapsed into a single category. Results: Significant differences (p ≤ .15) between quitters and relapsers were found in age, body mass index (BMI), income, alcohol consumption, and in the presence of full/partial PTSD diagnosis and of all three symptom clusters separately. Four logistic regression models predicting smoking cessation were modeled to control for confounding factors and included as independent variables a full/partial PTSD diagnosis and the three posttraumatic symptom clusters. The avoidance/numbing cluster presented the strongest association with relapse status (ORa 2.04, 95% CI [1.15, 3.63], p = .015), followed by the full/partial PTSD (ORa 1.80, 95% CI [1.04, 3.14], p = .038). The re-experiencing and the hyperarousal clusters were non-significantly associated with smoking cessation (ORa 1.34, 95% CI [0.80, 2.31], ns and ORa 1.65, 95% CI [0.96, 2.84], ns, respectively). Conclusions: Full/partial PTSD and posttraumatic symptom clusters uniquely predict risk for smoking relapse and thus may be a useful therapeutic target in trauma-exposed smokers.

Abstract
ABSTRACT To discuss the resilience factors that may have prevented a patient from developing post-traumatic stress disorder (PTSD) after exposure to a variety of severe potentially traumatic events. A thirty-eight-year-old civilian has been exposed to at least ten dramatic situations of violence in his work and personal life. He developed only a few mild post-traumatic symptoms after being exposed to a particularly gruesome incident during work. Even though the number and severity of potentially traumatic events may be alarming, this does not determine that the patient will inexorably develop PTSD, or other disorders. The study of protective factors is mandatory so that we can acknowledge and develop more effective ways to prevent and treat disorders.

Abstract
BACKGROUND The most recent editions of diagnostic manuals have proposed important modifications in posttraumatic stress disorder (PTSD) criteria. The International Trauma Questionnaire (ITQ) is the gold-standard measurement for assessing PTSD and complex PTSD in accordance with the model of the 11th International Classification of Diseases (ICD-11). OBJECTIVE The aim of this study was to adapt the ITQ for the Brazilian context. DESIGN AND SETTING The translation and cross-cultural adaptation of the ITQ for use in Brazilian Portuguese was performed in trauma research facilities in Porto Alegre, Rio de Janeiro and Belo Horizonte, Brazil. METHODS The adaptation followed five steps: (1) translation; (2) committee synthesis; (3) experts' evaluation through the content validity index (CVI) and assessment of interrater agreement though kappa statistics; (4) comprehension test with clinical and community samples (n = 35); and (5) final back-translation and authors' evaluation. RESULTS Two independent translations were conducted. While working on a synthesis of these translations, the committee proposed changes in six items to adapt idiomatic expressions or to achieve a more accurate technical fit. Both the expert judges' evaluation (CVI > 0.7; k > 0.55) and the pretest in the target population (mean comprehension > 3) indicated that the adapted items were adequate and comprehensible. The final back-translation was approved by the authors of the original instrument. CONCLUSION ITQ in its Brazilian Portuguese version achieved satisfactory content validity, thus providing a tool for Brazilian research based on PTSD models of the ICD-11.

Abstract
OBJECTIVE The goal of this study was to compare the clinical and functional status and the trauma-related characteristics of PTSD patients with comorbid OCD whose onset predated the index traumatic event (pre-traumatic OCD) with those of PTSD patient whose comorbid OCD only emerged after the exposure to the traumatic event (post-traumatic OCD). METHODS Sixty-three individuals with PTSD and comorbid OCD were evaluated with the Structured Clinical Interview for DSM-IV AXIS I Disorders and completed the Posttraumatic Stress Disorder Checklist - Civilian Version, the Beck Depression Inventory, the Beck Anxiety Inventory, the Trauma History Questionnaire and the 36-Item Short-Form Health Survey. RESULTS A history of childhood abuse was significantly more frequent among PTSD patients with pre-traumatic OCD (45.2%) than among their counterparts with post-traumatic OCD (16%). PTSD patients with pre-traumatic OCD had higher rates of psychiatric comorbidity in general and showed a lower functional health status in a physical domain (SF-36 Role Limitation due to Physical Health). In contrast, PTSD patients with post-traumatic OCD had a decreased functional health status in a psychological domain (SF-36 Emotional Well Being). The effect sizes were in the medium to large range. CONCLUSIONS A history of child abuse may be an important, but often neglected, factor accounting for clinical, functional, and trauma-related differences between pre-traumatic and posttraumatic OCD in PTSD patients.

Abstract
Childhood abuse and PTSD are independently associated with severe psychiatric comorbidity. We hypothesized that among patients with adult-onset PTSD, a history of child abuse was associated with increased prevalence and severity of comorbid mental disorders. Participants were 109 adult treatment-seeking patients, 23.9% of whom had a history of childhood sexual, physical or emotional abuse. The socio-demographic characteristics and comorbidity profile of PTSD patients with and without history of child abuse were compared using the two-tailed t-test and the chi-square test. PTSD patients with a history of child abuse had significantly higher average PCL-C hyperarousal [21.8 (SD = 3.6) vs 19.8 (SD = 3.5)] and BDI [35.7 (SD = 9.2) vs 29.1 (SD = 13.9)] scores, a significantly increased average number of lifetime [4.85 (SD = 1.43) vs 3.93 (SD = 1.33)] and current [4.46 (SD = 1.24) vs 3.75 (SD = 1.32)] comorbid disorders, and a greater prevalence of lifetime (73.1% vs 44.6%) and current (79.2% vs 46.7%) panic disorder/agoraphobia and of psychotic symptoms (73.1% vs 30.1%). All effect sizes were in the medium to large range. Adult-onset PTSD patients with a history of child abuse may represent a subgroup with a more severe form of the disorder that is associated with a more serious clinical course, treatment resistance and poorer outcome.

Abstract
Objective: To describe the process of cross-cultural adaptation of the Posttraumatic Stress Disorder Checklist 5 (PCL-5) and the Life Events Checklist 5 (LEC-5) for the Brazilian sociolinguistic context. Method: The adaptation process sought to establish conceptual, semantic, and operational equivalence between the original items of the questionnaire and their translated versions, following standardized protocols. Initially, two researchers translated the original version of the scale into Brazilian Portuguese. Next, a native English speaker performed the back-translation. Quantitative and qualitative criteria were used to evaluate the intelligibility of items. Five specialists compared the original and translated versions and assessed the degree of equivalence between them in terms of semantic, idiomatic, cultural and conceptual aspects. The degree of agreement between the specialists was measured using the content validity coefficient (CVC). Finally, 28 volunteers from the target population were interviewed in order to assess their level of comprehension of the items. Results: CVCs for items from both scales were satisfactory for all criteria. The mean comprehension scores were above the cutoff point established. Overall, the results showed that the adapted versions' items had adequate rates of equivalence in terms of concepts and semantics. Conclusions: The translation and adaptation processes were successful for both scales, resulting in versions that are not only equivalent to the originals, but are also intelligible for the population at large.

The impact of posttraumatic symptoms and comorbid mental disorders on the health-related quality of life in treatment-seeking PTSD patients. Compr Psychiatry 2015; 58:68-73. [PMID: 25656798 DOI: 10.1016/j.comppsych.2015.01.002] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2014] [Revised: 12/11/2014] [Accepted: 01/10/2015] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND There is a dearth of literature dealing with the impact of the severity of posttraumatic symptoms and of comorbid mental disorders on the health-related quality of life (HRQOL) of victims of civilian violence with a primary diagnosis of PTSD. OBJECTIVES To investigate the influence of the severity of posttraumatic symptoms and of presence of comorbid mental disorders on the HRQOL of treatment-seeking outpatients with PTSD. METHODS A sample of 65 PTSD patients was recruited in a specialized outpatient clinic. The volunteers had the diagnoses of PTSD and of comorbid mental disorders established with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). The severity of posttraumatic, depression and anxiety symptoms was measured with the PCL-C, BDI and BAI, respectively. HRQOL was assessed by means of the SF-36, a 36-item self-administered scale that measures eight domains of quality of life: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health. Multiple linear regression models were fitted to investigate the relationship between the severity of posttraumatic, mood, and anxiety symptoms; the presence of specific current comorbid disorders and of psychotic symptoms, and the number of current comorbid conditions for each of the eight domains of HRQOL, after adjusting for the effect of sociodemographic characteristics. RESULTS The severity of PTSD symptoms predicted worse HRQOL in all eight domains of SF-36, even after controlling for the severity of depression and anxiety symptoms, the presence of panic disorder, OCD, specific and social phobia, psychotic symptoms, and the number of comorbid disorders. The strongest negative association between PTSD symptoms severity and HRQOL was found in the Social Functioning domain. Although the inclusion of the depressive symptoms in the models led to a reduction of the magnitude of the negative association between the severity of PTSD symptoms and the HRQOL domain scores, the former still accounted for most of the explained variance of the latter. CONCLUSIONS We found that even in the presence of comorbid mental disorders, the severity of posttraumatic symptoms remained the strongest predictor for impaired HRQOL in PTSD outpatients. Our results suggest that improvement of HRQOL should be considered a therapeutic objective and an essential outcome measure in the treatment of PTSD.

Abstract
The treatment of anxiety is on the edge of a new era of combinations of pharmacologic and psychosocial interventions. A new wave of translational research has focused on the use of pharmacological agents as psychotherapy adjuvants using neurobiological insights into the mechanism of the action of certain psychological treatments such as exposure therapy. Recently, d-cycloserine (DCS) an antibiotic used to treat tuberculosis has been applied to enhance exposure-based treatment for anxiety and has proved to be a promising, but as yet unproven intervention. The present study aimed to evaluate the efficacy of DCS in the enhancement of exposure therapy in anxiety disorders. A systematic review/meta-analysis was conducted. Electronic searches were conducted in the databases ISI-Web of Science, Pubmed and PsycINFO. We included only randomized, double-blind, placebo-controlled trials with humans, focusing on the role of DCS in enhancing the action of exposure therapy for anxiety disorders. We identified 328 references, 13 studies were included in our final sample: 4 on obsessive-compulsive disorder, 2 on panic disorder, 2 on social anxiety disorder, 2 on posttraumatic stress disorder, one on acrophobia, and 2 on snake phobia. The results of the present meta-analysis show that DCS enhances exposure therapy in the treatment of anxiety disorders (Cohen d = −0.34; CI: −0.54 to −0.14), facilitating the specific process of extinction of fear. DCS seems to be effective when administered at a time close to the exposure therapy, at low doses and a limited number of times. DCS emerges as a potential new therapeutic approach for patients with refractory anxiety disorders that are unresponsive to the conventional treatments available. When administered correctly, DCS is a promising strategy for augmentation of CBT and could reduce health care costs, drop-out rates and bring faster relief to patients.

Abstract
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. The 54 volunteers also completed the Posttraumatic Stress Disorder Checklist - Civilian Version, the BDI, the BAI, the Trauma History Questionnaire, and a socio-demographic questionnaire. Quality of life was assessed by means of the WHOQOL-BREF, a 26-item self-administered scale that measures four domains of QoL: psychological, physical, social, and environmental. Multiple linear regression models were fitted to investigate the relationship between the severity of post-traumatic, mood, and anxiety symptoms; the presence of specific current comorbid disorders and of psychotic symptoms, the number of current comorbid conditions, and a history of child abuse for each of the four domains of QoL, after adjusting for the effect of socio-demographic characteristics. RESULTS The severity of PTSD symptoms impacted negatively on the psychological and physical domains. The severity of depressive symptoms correlated negatively with QoL in all domains, independently of sex, age, occupation, and marital status. The psychotic symptoms impacted negatively on the environmental domain. A history of child abuse was negatively associated with the psychological and the social domains. CONCLUSIONS The severity of comorbid depressive symptoms is one of the most important factors in the determination of the QoL in patients with PTSD.

Abstract
PURPOSE We sought to estimate the pooled current prevalence of posttraumatic stress disorder (PTSD) among rescue workers and to determine the variables implicated in the heterogeneity observed among the prevalences of individual studies. METHODS A systematic review covering studies reporting on the PTSD prevalence in rescue teams was conducted following four sequential steps: (1) research in specialized online databases, (2) review of abstracts and selection of studies, (3) review of reference list, and (4) contact with authors and experts. Prevalence data from all studies were pooled using random effects model. Multivariate meta-regression models were fitted to identify variables related to the prevalences heterogeneity. RESULTS A total of 28 studies, reporting on 40 samples with 20,424 rescuers, were selected. The worldwide pooled current prevalence was 10%. Meta-regression modeling in studies carried out in the Asian continent had, on average, higher estimated prevalences than those from Europe, but not higher than the North American estimates. Studies of ambulance personnel also showed higher estimated PTSD prevalence than studies with firefighters and police officers. CONCLUSIONS Rescue workers in general have a pooled current prevalence of PTSD that is much higher than that of the general population. Ambulance personnel and rescuers from Asia may be more susceptible to PTSD. These results indicate the need for improving pre-employment strategies to select the most resilient individuals for rescue work, to implement continuous preventive measures for personnel, and to promote educational campaigns about PTSD and its therapeutic possibilities.

Abstract
The DSM-IV-TR postulates that PTSD symptoms are organized into 3 clusters. This assumption has been challenged by growing number of factor analytical studies, which tend to favor 4-factor, first-order models. Our objective was to investigate whether the clusters of PTSD symptoms identified in North American and European studies could be replicated in a Brazilian sample composed of 805 primary care patients living in hillside slums. Volunteers were asked to fill out the Brazilian version of the Posttraumatic Stress Disorder Checklist-Civilian Version and a confirmatory factor analysis of this scale was conducted with the software LISREL 8.80. Seven models were tested and a 4-factor, first-order solution including an emotional numbing cluster was found to provide the best fit. Although PTSD has been characterized by some critics as a Western culture-specific disorder lacking universal validity, our results seem to uphold the cross-cultural validity of the 4-factor, first-order model.

Abstract
The World Psychiatric Association (WPA) Task Force and a small group previously convened by the WPA publications committee initiated three activities between 2006-2008 that aimed to respond to the need for greater support for psychiatry journals in LAMI countries. In a joint venture with participants from the Global Mental Health Movement the Task Force editors from LAMI countries in Africa, Asia, Eastern Europe and Latin America were contacted to identify potential journals to target for indexation (Medline and ISI). The committee analyzed the editors' applications on the following criteria: a) geographical representativeness; b) affiliation to a professional mental health society; c) regular publication of at least 4 issues per year over the past few years; d) comprehensive national and international editorial boards; e) publication of original articles, or at least abstracts, in English; f) some level of current indexation; g) evidence of a good balance between original and review articles in publications; and h) a friendly access website. The committee received 26 applications (11 from Latin America, 7 from Central Europe, 4 from Asia and 4 from Africa), and selected 8 journals, 2 from each geographical area, on the basis of the overall scores obtained for the items mentioned, to participate in an editors meeting held in Prague in September 2008. The aims of the committee are twofold: a) to concentrate support for those selected journals; and b) to assist all LAMI mental health editors in improving the quality of their journals and fulfilling the requirements for full indexation. This report summarizes the procedures conducted by the committee, the assessment of the current non-indexed journals, and offers suggestions for further action.

Abstract
Previous studies showed that heart period decreases during and recovers after an acute stress. We investigated if individual predispositions and emotional priming influence heart period recovery after a speech stress task. Psychometric scales and resting cardiac vagal tone were used to measure individual traits. The presentation of a sequence of either pleasant or unpleasant pictures, as emotional primers, preceded the speech stress. Heart period was measured throughout the experiment. Stress induced tachycardia irrespective of emotional priming or traits. In the recovery period, participants with higher resting cardiac vagal tone or presenting higher resilience significantly reduced the heart acceleration. Furthermore, these traits interacted synergistically in the promotion of the recovery of heart period. Pleasant priming also improved recovery for participants with lower negative affect. In conclusion, the stress recovery measured through heart period seemed dependent upon individual predispositions and emotional priming. These findings further strengthen previous observations on the association between greater cardiac vagal tone and the ability to regulate emotion.

Abstract
Glucocorticoids have a key role in stress responses. There are, however, substantial differences in cortisol reactivity among individuals. We investigated if affective trait and mood induction influence the reactivity to psychological stress in a group of 63 young adults, male (n=27) and female (n=36), aged ca. 21 years. On the experimental day the participants viewed either a block of pleasant or unpleasant pictures for 5 min to induce positive or negative mood, respectively. Then, they had 5 min to prepare a speech to be delivered in front of a video-camera. Saliva samples were collected to measure cortisol, and questionnaire-based affective scales were used to estimate emotional states and traits. Compared to basal levels, a cortisol response to the acute speech stressor was only seen for those who had first viewed unpleasant pictures and scored above the average on the negative affect scale. There were no sex differences. In conclusion, high negative affect associated with exposure to an unpleasant context increased sensitivity to an acute stressor, and was critical to stimulation of cortisol release by the speech stressor.

Abstract
OBJETIVOS: Nesta revisão narrativa, o objetivo foi descrever as opções farmacológicas para o tratamento do transtorno de estresse pós-traumático nos casos de intolerância, resistência, refratariedade ou impossibilidade de utilizar antidepressivos, especialmente inibidores seletivos da recaptação da serotonina. MÉTODO: Consulta às bases de dados ISI Web of Science e PubMed em busca de estudos originais sobre o tratamento farmacológico do transtorno de estresse pós-traumático em diferentes cenários clínicos. RESULTADOS: Evidências preliminares apontam para a utilidade de drogas como a risperidona, a olanzapina, a lamotrigina e o prazosin como estratégias para o cenário clínico em tela. A escolha do medicamento de segunda linha deve levar em conta não só os sintomas, como também as comorbidades, os tratamentos prévios, as interações farmacológicas, os efeitos colaterais e as condições físicas do paciente. CONCLUSÕES: Futuros ensaios clínicos randomizados ainda são necessários para estabelecer com clareza alternativas farmacológicas aos antidepressivos para o tratamento do transtorno de estresse pós-traumático.

Abstract
The International Classification of Diseases, 10th edition (ICD-10) defines atypical bulimia nervosa (ABN) as an eating disorder that encompasses several different syndromes, including the DSM-IV binge eating disorder (BED). We investigated whether patients with BED can be differentiated clinically from patients with ABN who do not meet criteria for BED. Fifty-three obese patients were examined using the Structured Clinical Interview for DSM-IV and the ICD-10 criteria for eating disorders. All volunteers completed the Binge Eating Scale (BES), the Beck Depression Inventory, and the Symptom Checklist-90 (SCL-90). Individuals fulfilling criteria for both ABN and BED (N = 18), ABN without BED (N = 16), and obese controls (N = 19) were compared and contrasted. Patients with ABN and BED and patients with ABN without BED displayed similar levels of binge eating severity according to the BES (31.05 +/- 7.7 and 30.05 +/- 5.5, respectively), which were significantly higher than those found in the obese controls (18.32 +/- 8.7; P < 0.001 and P < 0.001, respectively). When compared to patients with ABN and BED, patients with ABN without BED showed increased lifetime rates of agoraphobia (P = 0.02) and increased scores in the somatization (1.97 +/- 0.85 vs 1.02 +/- 0.68; P = 0.001), obsessive-compulsive (2.10 +/- 1.03 vs 1.22 +/- 0.88; P = 0.01), anxiety (1.70 +/- 0.82 vs 1.02 +/- 0.72; P = 0.02), anger (1.41 +/- 1.03 vs 0.59 +/- 0.54; P = 0.005) and psychoticism (1.49 +/- 0.93 vs 0.75 +/- 0.55; P = 0.01) dimensions of the SCL-90. The BED construct may represent a subgroup of ABN with less comorbities and associated symptoms.

Abstract
INTRODUÇÃO: O transtorno do estresse pós-traumático (TEPT) é bastante prevalente, atingindo de 2 a 5% da população em alguns países. Seus portadores apresentam pior qualidade de vida, maior número de detenções e problemas legais, e utilizam os serviços de saúde com maior freqüência quando comparados a indivíduos não acometidos. Apesar do crescimento da violência urbana no Brasil, ainda não dispomos de nenhum instrumento adaptado para nossa língua que seja capaz de rastrear o TEPT. Este artigo pretende traduzir, adaptar e avaliar a aplicabilidade da versão em português da Post-Traumatic Stress Disorder Checklist - Civilian Version (PCL-C), uma escala auto-aplicável amplamente utilizada em todo o mundo para rastreamento do transtorno do estresse pós-traumático. MÉTODOS: A comprovação da equivalência semântica da versão em português da PCL-C foi feita através de quatro etapas: tradução; retradução; apreciação formal de equivalência e adaptação; e interlocução com a população-alvo. RESULTADOS: Foi criada uma versão em português da PCL-C que manteve o significado semântico da versão original e mostrou-se de fácil compreensão e aplicabilidade. DISCUSSÃO: A PCL-C foi escolhida para este estudo por ser um instrumento amplamente utilizado em países de língua inglesa e por possuir outras utilidades além do rastreamento do TEPT. A interlocução com a população-alvo, feita com um número relativamente pequeno de indivíduos (n = 21), mostrou que alguns participantes entenderam o termo "estresse" como uma rotina de vida cansativa. CONCLUSÃO: Uma vez obtida a equivalência semântica da versão em português da PCL-C, estudos posteriores deverão determinar suas características psicométricas para a população brasileira.

Abstract
OBJECTIVE To describe a different type of self-injurious behavior that may be secondary to body dysmorphic disorder (BDD). METHOD Single case report. RESULTS We reported a case of an individual who have developed the self-destructive habit of pulling and severely scraping hairs and debris out of the mucous membrane of his nasal cavities. We have proposed the term rhinotrichotillomania to emphasize the phenomenological overlapping between trichotillomania (TTM) and rhinotillexomania (RTM) exhibited by this case. The main motivation behind the patient's actions was a distressing preoccupation with an imaginary defect in his appearance, which constitutes the core characteristic of BDD. The patient was successfully treated with imipramine. CONCLUSION The case suggests that certain features of TTM, RTM, and BDD may overlap and produce serious clinical consequences. Patients with this condition may benefit from a trial of tricyclics when other effective medications, such as serotonin reuptake inhibitors, are not available for use.

Abstract
Actigraphy has been used to monitor individuals' sleep and wakefulness patterns without laboratory confinement. To date, its validity in monitoring sleep and wakefulness among patients with major depressive episodes has not been systematically examined. The present study investigated whether the normative criteria of the Actigraph Data Analysis Software, initially optimized for healthy individuals, could score wrist-activity data accurately in a sample of depressed patients. Application of the normative algorithm yielded a correlation coefficient of 0.85 and an average error of 35 min, comparing actigraphic and polysomnographic sleep estimates. The algorithm optimized for this sample provided a correlation coefficient of 0.81 and an error of 6 minutes. For both algorithms, agreement for individual comparisons varied substantially. These findings suggest that scoring criteria optimized on wrist-activity data of healthy young adults may not produce optimal results for patients characterized with major depressive episodes.

Abstract
Kleine-Levin syndrome is characterized by periodic hypersomnia, hyperphagia, sexual disinhibitions and behavioral disturbances. The prognosis is generally benign, with normal cognitive and social functions after the episodes. We describe a typical case of Kleine-Levin syndrome associated with apparent academic decline, neuropsychological sequelae and personality alterations after the second episode of the illness. Further research in the natural history of Kleine-Levin syndrome is needed, for example, to determine whether early intervention would improve long-term prognosis.

Abstract
OBJECTIVE Quality-of-life indices have been used in medical practice to estimate the impact of different diseases on functioning and well-being and to compare outcomes between different treatment modalities. An integrated view of the issue of quality of life in patients with anxiety disorders can provide important information regarding the nature and extent of the burden associated with these disorders and may be useful in the development of strategies to deal with it. METHOD A review of epidemiological and clinical studies that have investigated quality of life (broadly conceptualized) in patients with panic disorder, social phobia, posttraumatic stress disorder, generalized anxiety disorder, and obsessive-compulsive disorder was conducted by searching MEDLINE and PsycLIT citations from 1984 to 1999. A summary of the key articles published in this area is presented. RESULTS The studies reviewed portray an almost uniform picture of anxiety disorders as illnesses that markedly compromise quality of life and psychosocial functioning. Significant impairment can also be found in individuals with subthreshold forms of anxiety disorders. Effective pharmacological or psychotherapeutic treatment has been shown to improve the quality of life for patients with panic disorder, social phobia, and posttraumatic stress disorder. Limitations in current knowledge in this area are identified, and suggestions for needed future research are provided. CONCLUSIONS It is expected that a more thorough understanding of the impact on quality of life will lead to increased public awareness of anxiety disorders as serious mental disorders worthy of further investment in research, prevention, and treatment.

Abstract
The Unified Biosocial Theory of Personality postulates that human personality is organized around four temperaments - Novelty Seeking, Harm Avoidance, Reward Dependence, and Persistence - and three characters - Self-Directedness, Cooperativeness, and Self-Transcendence. The objective of the present study was to investigate the influence of sociodemographic factors on temperament and character without the confounding influence of mental disorders. Volunteers (n=94) did not meet criteria for any Axis I and Axis II diagnosis, had no first-degree relatives with mental disorders, and were medically healthy. After giving written informed consent, volunteers completed the Temperament and Character Inventory. Analyses were conducted to determine the degree of association of each sociodemographic factor (i.e., age, gender, ethnicity, marital status, educational attainment, and occupational status) to personality dimension, while controlling for possible interactions with other sociodemographic factors. Partial correlation analysis showed a significant association between gender and Reward Dependence, and occupational status was significantly related to Reward Dependence, Cooperativeness, and Self-Transcendence. Stepwise regression analysis indicated that gender and occupational status were significant predictors of Reward Dependence. Occupational status was the only predictor of Cooperativeness and Self-Transcendence. These data suggest that sociodemographic factors should be considered in studies investigating temperaments and characters as defined by the Unified Biosocial Theory of Personality.

Abstract
Research evidence suggests that actigraphy is a very important instrument in documenting sleep/wake patterns of people with a variety of sleep disorders or motor dysfunctions. The present actigraphic investigation examined physical activity and sleep profiles as a function of gender in volunteers monitored in their natural environment. Irrespective of age, women exhibited better sleep quality than did men. This was demonstrated by higher sleep efficiency index and lower frequency of transitions between sleep and wakefulness. Additionally, women slept more than men and had shorter sleep onset latency. However, no significant gender effect on daytime activity level and circadian activity amplitude was observed.

Abstract
OBJECTIVE Depressed mood is one of the essential features for the diagnosis of major depression. Evidence from the three-site Epidemiologic Catchment Area study (ECA, Baltimore, Durham and Los Angeles) suggests a prevalence of 4.4% of depressive symptoms in the community. In this study, we examined whether depressed mood, as coded in the Alzheimer's Disease Assessment Scale, would be correlated with actigraphic-derived daytime activity and sleep/wake parameters in a non-psychiatric sample. METHOD Consenting volunteers were monitored at home for 5 days with a wrist actigraph. On the last day of the recording, they were given a neuropsychological battery including the Alzheimer's Disease Assessment Scale. RESULTS Daytime activity level was the best predictor of depressed mood as indicated by a logistic regression analysis. The regression model further suggested that sleep onset latency, total time asleep, and time in bed were also significant predictors of depressed mood. CONCLUSION This investigation demonstrates that daytime activity level could be used as an index of depressed mood even in a non-psychiatric sample. Further, the results support the notion that depression should be considered more as a continuum rather than as a set of rigid categories.

Abstract
This is a retrospective study of mothers charged with killing their children within 24 h of birth in the city of Rio de Janeiro, Brazil. Characteristics of the mothers and the victims, the circumstances surrounding the offense, the mothers' motivation and state of mind at the time of the offense, the legal process, and follow-up data were investigated. We analyzed our cohort as two sub-groups: 26 offenses that occurred between 1900 and 1939 and were dealt with under the Brazilian Penal Code of 1890, and 27 offenses that were committed between 1940 and 1995 and were dealt with under the Penal Code of 1940. The mothers were young (mean 22.5 +/- 5.3 years), unmarried (88.2%), non-Caucasian (73.8%), and had limited formal education. They usually kept the pregnancy a secret (94.1%) and gave birth in a classified way (100%). Most victims were killed through wounding violence (77.4%). Offenders identified between the years of 1940-1995 had increased rates of literacy (chi 2 = 6.80, d.f. = 1, p = .009), a higher incidence of reported psychiatric symptoms (chi 2 = 11.82, d.f. = 1, p < .001), increased referral for psychiatric assessment (chi 2 = 3.85, d.f. = 1, p = .05), and greater frequency of cases where statute of limitations was expired (chi 2 = 3.88, d.f. = 1, p = .049).

Abstract
Recent studies of patients with affective disorders have found that there are biological differences between inpatients and outpatients. Concerned by these findings, we compared individuals admitted to our inpatient and outpatient affective disorders clinical research center who met criteria for major depression. We hypothesized that inpatients would be more severely ill, more suicidal, more functionally impaired, and have more co-morbid disorders and higher ratings of depression and mood state dysfunction. The demographic profiles, lifetime co-morbid Axis I diagnoses, consumption histories, symptom profiles, global assessment of functioning, and severity of current stressors (Axis IV) were compared and contrasted for the two groups. Inpatients had more severe current psychosocial stressors, lower current levels of functioning, increased lifetime co-morbid Axis I diagnoses, and increased rates of psychiatric hospitalizations, however, they did not have higher depression symptom ratings. In conclusion, inpatients and outpatients differed significantly in the severity of their stressors, coping abilities and history of previous hospitalizations, but not in most demographic variables or their current symptoms of depression.
