A summary of the reliability and stability of MMPI scales.
A sample of MMPI research published between 1970 and 1981 was analyzed to yield reliability and stability estimates for the MMPI scales. In fundamental agreement with previous research, moderately high levels of reliability and stability were found for all scales. Reliability values ranged from .71 to .84; stability values ranged from .63 to .86. These findings are based on thousands of adult subjects from college, psychiatric, medical, alcohol or drug rehabilitation, and prison populations. The present scale estimates have wide generalizability and, therefore, should be of value to clinicians and researchers in various settings.
