External correlates of the MMPI-2 restructured clinical scales in an American Indian outpatient sample
The MMPI-2 is one of the most widely used psychological instruments to aid in assessing psychopathology. Based on lack of construct validity, low discriminant validity, and high intercorrelations among the Basic Clinical Scales, Tellegen, Ben-Porath, McNulty, Arbisi, Graham, and Kaemmer (2003) developed the Restructured Clinical (RC) Scales for the MMPI-2. Recent research with the RC Scales demonstrates superior interpretation of the clinical scales with solid relationship to external correlates with Caucasian and African American participants. Of the 10,249 studies completed on the MMPI and MMPI-2, only 17 were found that incorporated American Indian participants. No studies were found using the RC Scales with American Indians. Since cultural variables influence personality characteristics (Edwards, 1957) and test responding, the RC Scales are examined as an assessment tool to investigate its use with American Indians in an outpatient sample. The overall results of the Basic Clinical Scales and-the Restructured Clinical-Scales did not reveal any clinically significant elevations in this sample, although when the demographic subgroups were examined, relevant clinically and significant elevations emerged, offering some insight into demographic risk factors for mental illness domains. Examination of External Correlates (rated from chart information) was instrumental for discovering specific factors that may drive the clinically significant elevations for various mental illness domains. Overall, the MMPI-2 is an acceptable assessment tool for this sample population, although interpretation needs to be done with extreme caution.
