Behavioral correlates of single-scale MMPI code types

Attempted to determine whether reliable demographic and behavioral correlates could be found for singe-scale Minnesota Multiphasic Personality Inventory (MMPI) code types. Ss were 661 patients in a psychiatric hospital. Utilizing a split-sample technique to allow for replication, high-point, low-point, high-score, and low-score code types were studied. Each code type was compared with other Ss on 73 demographic and behavioral variables. Separate analyses were done for male and female code types. Only correlates reliable across both samples are reported. A sufficiently large number of reliable correlates were identified, suggesting that single-scale code types can be considered a meaningful approach to MMPI interpretation. The importance of using replication procedures was confirmed. (24 ref)
