In 2003, the Restructured Clinical scales were added to the published MMPI-2, representing a reconstruction of the original clinical scales designed to address known psychometric flaws in the original clinical scales that unnecessarily complicated their interpretability and validity, but could not be addressed at the same time as the restandardization process.Specifically, Demoralization – a non-specific distress component thought to impair the discriminant validity of many self-report measures of psychopathology – was identified and removed from the original clinical scales. Restructuring the clinical scales was the initial step toward addressing the remaining psychometric and theoretical problems of the MMPI-2. In 2008, the MMPI-2-RF (Restructured Form) was published to psychometrically and theoretically fine-tuned the measure. The MMPI-2-RF contains 338 items, contains 9 validity and 42 homogeneous substantive scales, and allows for a straightforward interpretation strategy. The MMPI-2-RF was constructed using a similar rationale used to create the Restructured Clinical (RC) scales. The rest of the measure was developed utilizing statistical analysis techniques that produced the RC scales as well as a hierarchical set of scales similar to contemporary models of psychopathology to inform the overall measure reorganization.
