| Abstract: | The current study examined the MMPI-2 Restructured Clinical (RC) scales (Tellegen et al., MMPI-2 Restructured Clinical (RC) scales: Development, validation, and interpretation. Minneapolis: University of Minnesota Press, 2003) in a sample of 1,091 bariatric surgery candidates. The RC scales were
developed to address concerns about limited discriminant validity of the Clinical scales. Internal consistency and external
validity analyses were conducted to evaluate the RC scales in this setting. Results indicated that the RC scales are generally
more internally consistent than the Clinical scales and display significantly better convergent and discriminant validity
in predicting a variety of behavioral, psychological, and developmental variables relevant to preoperative bariatric psychological
evaluations. Implications of the results and recommendations for future research with the RC scales in medical settings are
discussed. |
