Portuguese Version of the Posttraumatic Stress Disorder Checklist for
DSM-5 (PCL-5): Comparison of Latent Models and Other Psychometric
Analyses
Abstract
The PCL (Weathers et al., 1993) is a useful and widely used measure to
assess PTSD symptoms in clinical and research contexts, exhibiting
adequate psychometric properties across its several versions and
translations (e. g. Carvalho et al., 2015; Wilkins et al., 2011). The
current study analyzed the psychometric properties (latent structure,
internal consistency, temporal reliability, and convergent validity) of
the Portuguese version of the PCL for the DSM-5 (PCL-5, Weathers et al.,
2013) in a sample of firefighters. This study also aimed to contribute
with empirical data to clarify the best latent structure of DSM-5 PTSD
symptoms. Specifically, the DSM-5 four-factor model and other competing
models for PTSD symptoms (four-factor Dysphoria model, five-factor
Dysphoric Arousal model, six-factor Anhedonia model, six-factor
Externalizing Behavior model, and seven-factor Hybrid model) applied to
PCL-5 were analyzed and compared in this paper.
