Drs Rey et al believe that the high reliability obtained in the DSM-III field trial may only have been due to the fact that the pairs of interviewers each worked together at the same facility and therefore probably had "the same biases." During the field trial itself, we were well aware that this was a potential source of bias. Therefore, in an effort to explore whether the relatively high diagnostic reliability achieved could be due to the fact that interviewing partners shared similar training, experience, and theoretical orientation toward diagnosis, we conducted a substudy reported in the Archives.1 Essentially, case summaries were sent to 35 clinicians at different facilities who had participated in the live reliability study, to undergo diagnosis using the DSM-III multiaxial system. Several months later, the same case summaries were sent to the clinicians who had been the partners of these raters in the live
