Background: The Posttraumatic Stress Disorder Checklist Scale (PCLS) is a short self-report inventory for assessing the 3 main syndromes of Posttraumatic Stress Disorder (PTSD). The aim of this study was the validation of the French version of the PCLS in PTSD subjects and nonclinical subjects. Methods: One-hundred and thirteen outpatients suffering from PTSD according to DSM-IV were administered the PCLS. The patients’ scores on the PCLS were then compared to those of 31 nonclinical control subjects. Thirty-five of the patients were administered the PCLS twice over an interval of 1–2 weeks and also completed questionnaires measuring depression, phobia and anxiety. Results: The patients’ total score and subscores on the PCLS were found to be significantly higher than those of control subjects. The cutoff score of 44 on the French version PCLS distinguishes well between the PTSD group and control group with a high diagnostic efficacy (0.94). Factor analysis revealed 3 main factors corresponding to the reexperiencing, numbing and hyperarousal syndromes. The PCLS showed satisfactory test-retest reliability and internal consistency. Conclusions: The PCLS is therefore a valid and effective measurement of PTSD. It may be a useful tool for screening and assessing PTSD in psychiatric as well as in primary-care settings.
Early experience with faces of a given racial type facilitates visual recognition for this type of face relative to others. To assess whether this so-called other-race effect can be reversed by subsequent experience with new types of faces, we tested adults of Korean origin who were adopted by European Caucasian families when they were between the ages of 3 to 9. The adoptees performed a face recognition task with photographs of Caucasian and Asian faces. They performed exactly like a control group of French participants, identifying the Caucasian faces better than the Asiatic ones. In contrast, a control group of Koreans showed the reverse pattern. This result indicates that the face recognition system remains plastic enough during childhood to reverse the other-race effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
