Clinical applications of the MCMI: the 1-2-3-8 codetype.

The MCMI profiles of 131 psychiatric inpatients were examined to identify 1-2-3-8 codetypes on the basic personality scales, which reflect a schizoid, avoidant, dependent, and passive-aggressive blend of personality traits. Approximately 25% of the inpatient sample obtained the 1-2-3-8 codetype. Analyses of the diagnoses and clinical records of these patients suggest that this profile reflects an affect/mood disturbance with prominent depressive features and suicidal ideation/attempt prior to admission. This investigation serves mainly as a stimulus for research questions that should be addressed in order to increase the range of clinical applications of the MCMI and the body of empirical literature that can support the utility of this assessment device.
