Multivariate cluster analysis of the MMPI-2 in chronic low-back pain patients.
OBJECTIVE
The 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.


METHODS
A multidisciplinary pain clinic in the southeastern United States.


METHODS
The subjects were 201 chronic low-back pain patients who had suffered a work-related back injury.


METHODS
The Minnesota Multiphasic Personality Inventory-2.


RESULTS
We 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.


CONCLUSIONS
These 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.
