Confirmatory factor analysis of posttraumatic stress symptoms in Brazilian primary care patients: An examination of seven alternative models

Reliability and validity of the Arabic PTSD Checklist Civilian Version (PCL‐C) in women survivors of intimate partner violence

“…A number of studies have been conducted to find the best representation of PTSD's underlying dimensions, or how the symptoms must be organized or grouped (Armour, ; Elhai & Palmieri, ). However, these studies have generally failed to replicate the three‐factor structure of the DSM‐IV (Cernvall, Alaie, & Essen, ; Costa et al, ; Elhai & Palmieri, ). Rather, they have provided support for three alternative conceptual models: (i) a four‐factor Emotional Numbing model (King, Leskin, King, & Weathers, ); (ii) a four‐factor Dysphoria model (Simms, Watson, & Doebbeling, ); and (iii) a five‐factor Dysphoric Arousal model (Elhai et al, ).…”

The impact of posttraumatic symptoms and comorbid mental disorders on the health-related quality of life in treatment-seeking PTSD patients

“…The PCL-C score ranges from 17 to 85, with higher values implying more severe PTSD symptoms. The Brazilian-Portuguese version of PCL-C has good internal consistency (Cronbach's α = .89) and testretest reliability (r = .83) [17][18][19]41]. …”

Factor structure, internal consistency and reliability of the Posttraumatic Stress Disorder Checklist (PCL): an exploratory study

“…4,7,19,24,26,27 The only confirmatory study conducted in Brazil suggests that this model provides the best fit for the PCL factor structure. 23 The dysphoria model includes the clusters reexperiencing (B1-B5) and avoidance (C1-C2), and combines components of hyperarousal (D1-D3) and…”

“…The third study was conducted with 805 primary care patients living in a poor area of Rio de Janeiro. 23 The sample was heterogeneous regarding sociodemographic characteristics and exposure to traumatic events. The authors used CFA to compare seven alternative PTSD models.…”
