Response to barglow letter.

摘要

To the Editor: I challenge the assertion in the January editorial by Freedman et al. (1) on DSM-5 reliability statistics that posttraumatic stress disorder (PTSD) "is another historic accomplishment, with a kappa of 0.67." Since the majority of the 960 adult PTSD patients who were sampled for DSM-5 were interviewed at Veterans Affairs facilities, high rater concordance is not surprising (2). The notoriety and secondary gain associated with this disorder at these treatment locations probably concretized patients' diagnostic self-identifications, which were most likely communicated to and adopted by the research interviewers.
