ObjectiveThe purpose of our study was to investigate whether Minnesota Multiphasic Personality Inventory-2 cluster solutions of chronic low-back pain patients would replicate those found in previous research with the Minnesota Multiphasic Personality Inventory.SettingA multidisciplinary pain clinic in the southeastern United States.PatientsThe subjects were 201 chronic low-back pain patients who had suffered a work-related back injury.Outcome MeasuresThe Minnesota Multiphasic Personality Inventory-2.ResultsWe found four relatively homogeneous subgroups of chronic low-back pain patients that were similar to those identified by previous researchers using data collected with the Minnesota Multiphasic Personality Inventory.ConclusionThese findings indicate that interpretations of the Minnesota Multiphasic Personality Inventory-2 should parallel those of the Minnesota Multiphasic Personality Inventory for chronic low-back pain patients. They further suggest that the results of Minnesota Multiphasic Personality Inventory-based studies are also applicable to Minnesota Multiphasic Personality Inventory-2.
