PORTUGUESE VALIDATION OF THE PERINATAL PTSD QUESTIONNAIRE (PPQ)

Dusunen Adam The Journal of Psychiatry and Neurological Sciences , 2020

Objective: The aim of this study is to adapt the Perinatal Post Traumatic Stress Disorder Questionnaire- II (PPQ-II) and determine the psychometric properties of this scale. Method: The study was conducted with two different samples consisting of mothers who give full-term and preterm birth. To investigate the factor structure and conduct confirmatory factor analysis, the first sample was composed of 194 women between the ages of 18-43 (Mean=30.12, standard deviation [SD]=4.96). The second sample in which confirmatory factor analysis was conducted consisted of 238 women between the ages of 19-43 (Mean=30.33, SD=4.00). Depression Anxiety Stress Scale and Connor-Davidson Resilience Scale were used in this study as well as PPQ-II. Results: The exploratory and confirmatory factor analysis revealed a two-factor structure named “Intrusive Thoughts and Avoidance” and “Hyperarousal and Numbness Responses”. The model obtained by confirmatory factor analysis demonstrated acceptable goodness of fit values and the questionnaire was found to have satisfactory reliability and validity values. Conclusion: PPQ-II could be considered as a valid and reliable scale which could be used in maternal mental health studies conducted in Turkey. Keywords: Factor analysis, perinatal trauma, PTSD, reliability, validity

ObjectiveThere is no validated Persian questionnaire to measure childbirth-related PTSD (CB-PTSD) symptoms. To cover this gap, the present study aimed to provide a Persian version of the City Birth Trauma Scale (CityBiTS-Pr) and to determine its psychometric properties.MethodSince this is a cross-sectional study, sampling was done using a convenient sampling method. In total, 300 Persian-speaking women took part in this study and completed the City Birth Trauma Scale (CityBiTS-Pr), the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), the Edinburgh Postnatal Depression Scale (EPDS), the Anxiety Subscale of the Depression, and the Anxiety and Stress Scale (DASS-21). In addition, sociodemographic information was completed. A confirmatory factor analysis of two- and four-factor models and a bi-factor model with a general factor and two specific factors were tested. Fit indices were calculated for all three models. Reliability, convergent, divergent, and discriminant validity a...

Background Global crises inevitably increase levels of anxiety in postpartum populations. Effective and efficient measurement is therefore essential. This study aimed to create a 12-item research short form of the 51-item Postpartum Specific Anxiety Scale [PSAS] and validate it for use in rapid response research at a time of global crises [PSAS-RSF-C]. We also present the same 12-items, in five other languages (Italian, French, Chinese, Spanish, Dutch) to increase global accessibility of a psychometric tool to assess maternal mental health. Methods Twelve items from the PSAS were selected on the basis of a review of their factor loadings. An on-line sample of UK mothers (N = 710) of infants up to 12 weeks old completed the PSAS-RSF-C during COVID-19 ‘lockdown’. Results Principal component analyses on a randomly split sample (n = 344) revealed four factors, identical in nature to the original PSAS, which in combination explained 75% of the total variance. Confirmatory factor analyses...

Objectives. To evaluate instruments used to assess posttraumatic stress disorder (PTSD) following childbirth with both quantitative (reliability analysis and factor analysis) and qualitative (comparison of operationalization) techniques.

Objective: City Birth Trauma Scale is a recently developed scale specifically designed for evaluation of posttraumatic stress disorder (PTSD) following childbirth based on the DSM-5 criteria (Ayers, Wright, & Thornton, 2018). Previous studies showed a two-factor structure of PTSD symptoms in postpartum women; however, more complex models were not tested. This study aimed to validate the Croatian version of the City Birth Trauma Scale and determine the latent factor structure of postpartum PTSD. Method: In a cross-sectional study, 603 women completed online questionnaires comprising City Birth Trauma Scale, Impact of Event Scale-Revised (IES-R), Edinburgh Postnatal Depression Scale (EPDS), and the anxiety subscale from the Depression, Anxiety, and Stress Scale (DASS-21). Results: Confirmatory factor analysis confirmed the bifactor model of Birth-related symptoms (re-experiencing and avoidance) and General symptoms was an excellent fit to the data. Both subscales and the total scale showed high internal consistency (α = .92). Convergent and divergent validity testing showed high validity, especially for Birth-related symptoms. Discriminant validity was confirmed with primiparous women and women who gave birth by instrumental vaginal delivery and emergency caesarean section having significantly higher scores on Birth-related symptoms, but not on General symptoms, suggesting high discriminant validity of the Birth-related symptoms subscale. Conclusions: The City Birth Trauma Scale is a reliable and valid measure. Both total scale score and subscale scores can be calculated. It is highly recommended for use in postpartum population.

Introduction: The aim of this study was to translate and validate into European Portuguese the CAPS-CA-5 (Clinician Administered PTSD Scale for Children and Adolescents), a semi-structured scale for the diagnosis of post-traumatic stress disorder in children and adolescents, according to the DSM-5 criteria.Material and Methods: This study was developed in three stages. In the first stage, the translation and back-translation of CAPS-CA-5 into European Portuguese was carried out. In the second stage, the version obtained in the previous step was subjected to a pre-test. In the third stage, the final version of CAPS-CA-5, the KIDCOPE questionnaires and the Depression, Anxiety and Stress Scale-Children were applied to 101 children who had experienced at least one potentially traumatic event. The children included in this study were between seven and 18 years old and had a follow-up period in a Child Psychiatry or Pediatrics Clinic in one of the three hospitals involved in this project ...

The PTSD Checklist-civilian (PCL-C) is one of the most commonly used self-report measures of PTSD symptoms, however, little is known about its validity when used in pregnancy. This study aims to evaluate the reliability and validity of the PCL-C as a screen for detecting PTSD symptoms among pregnant women. A total of 3372 pregnant women who attended their first prenatal care visit in Lima, Peru participated in the study. We assessed the reliability of the PCL-C items using Cronbach's alpha. Criterion validity and performance characteristics of PCL-C were assessed against an independent, blinded Clinician-Administered PTSD Scale (CAPS) interview using measures of sensitivity, specificity and receiver operating characteristics (ROC) curves. We tested construct validity using exploratory and confirmatory factor analytic approaches. The reliability of the PCL-C was excellent (Cronbach's alpha =0.90). ROC analysis showed that a cut-off score of 26 offered optimal discriminatory p...
