    The factor structure of DSM-5 posttraumatic stress disorder (PTSD) has been extensively debated, with evidence supporting the recently proposed seven-factor hybrid model. However, few studies examining PTSD symptom structure have assessed the implications of these proposed models on diagnostic criteria and PTSD prevalence. In the present study, we examined seven alternative DSM-5 PTSD models within a confirmatory factor analysis (CFA), using the Child PTSD Symptom Scale–Self-Report for DSM-5 (CPSS-5). Additionally, we generated prevalence rates for each of the seven models by using a symptom-based diagnostic algorithm and assessed whether substance abuse, depression, anxiety symptoms, and daily functioning were differentially associated with PTSD depending on the model used to derive the diagnosis. Participants were 317 adolescents aged 13–17 years (M = 15.93, SD = 1.23) who had experienced a DSM-5 Criterion A trauma and/or childhood adversity. The CFA results showed good fit indices for all models, with the seven-factor hybrid model presenting the best fit. The rates of PTSD diagnosis varied according to each model. The four-factor DSM-5 model presented the highest rate (30.6%), and the seven-factor hybrid model presented the lowest rate (17.4%). Similar to the CFA analysis, the inclusion criteria for the diagnosis based on the hybrid model also presented the strongest associations with daily functional impairment, odds ratio (OR) = 1.48, 95% CI [1.25, 1.75]; and adverse childhood experiences, OR = 1.46, 95% CI [1.16, 1.82]. Research and clinical implications of these results are discussed, and suggestions for future investigation are presented.

    Shelter versus living with abusive partner : differences among mothers and children exposed to intimate partner violence
    (Springer New York, 2019-10-01) Pinto, Ricardo J.; Lamela, Diogo; Simães, Clara; Levendosky, Alytia; Jongenelen, Inês; HEI-LAB - Human Environment Interaction Lab
    Objectives: A growing body of literature has examined differences in the mental health and social support of abused women living in shelters compared with women from the community. However, less attention has been given to the differential effects of living in shelters and living with abusive partner in both mothers and children. A cross-sectional study was carried out to examine differences on cortisol awakening response (CAR), depression, anxiety and post-traumatic stress symptoms, and social support in a Portuguese sample of women living in shelter compared to women living with abusive partner. Mothers also reported on their children’s internalizing and externalizing symptoms. Methods: The sample included 162 mothers and their children (4–10 years of age), of whom 81 were living with the abusive partner and 81 were living in shelters. Results: After adjusting for covariates, mothers living in shelters showed better psychological, physiological and social functioning. In contrast, children living in shelters displayed higher levels of internalizing and externalizing symptoms compared with children living at home with their mothers and abusive partners. Conclusions: This study suggests that for women, shelter residence may be helpful for mental health and for significant improvements in perceived social support, but for children, the results seem to suggest that they are not benefiting from the time they spend at shelter. Future studies using samples from women in shelters need to evaluate if the services offered are suitable for children’s needs.
