Psychometric characteristics of the cluster B personality disorders under DSM-III-R and DSM-IV.
A stated goal for the latest revision of the DSM was improving the performance of the Axis II system. To evaluate the degree to which this goal was achieved, we performed a psychometric analysis of the Cluster B personality disorders (PD) as they are defined under the DSM-III-R and its successor the DSM-IV. Ninety-four patients with a primary PD diagnosis were rated for the presence of DSM-III-R and DSM-IV Cluster B PD criteria. From this symptom level data, the convergence, divergence, and internal consistency of the Cluster B criteria sets were determined. Also, kappa values were computed between the DSM-III-R and DSM-IV versions of these disorders as an index of coverage or agreement across the two systems. The results indicated that, in general, the DSM-IV Cluster B PDs represent an improvement over their DSM-III-R predecessors. However, some psychometric limitations, particularly regarding the convergence of the criteria sets, continue to be present.
