Validity of a computerized on-line MMPI interpretive system
Journal of Clinical Psychology
|May 1, 1983
Abstract:
Three independent, experienced clinicians trained at the University of Minnesota were asked to rate the quality and accuracy of codetype interpretations and associated rules used in the Psych Systems' automated MMPI program. Results showed that this system is rated highly by clinicians. The authors discuss how this approach can be used in validating other automated test interpretation systems and suggest that feedback by expert judges can be used to improve such systems.

Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
