Abstract

Objective
: This study aimed to find out whether the Minnesota Multiphasic Personality Inventory-2-Re-structured Form (MMPI-2-RF) scales are useful in distinguishing social anxiety disorder, panic disorder, and major depressive disorder.
Methods
: The study sample included 118 patients: 33 with social anxiety disorder, 53 with major depres-sive disorder, and 32 with panic disorder. Participants were classified according to the diagnosis indicated on their medical records. MMPI-2-RF scores were derived from MMPI-2 protocols.
Results
: The results of multivariate analysis of variance showed that the elevated scales were consistent with the diagnostic and clinical characteristics of each diafnostic group. Logistic regression analyses identified several scales that were useful in differentiating the diagnostic groups. The higher Cognitive Complaints (COG) scale significantly differentiated major depressive disorder from the other groups. The higher Self-Doubt (SFD) scale and Somatic Complaints (RC1) scale were useful in differentiating social anxiety disorder and panic disor-der respectively. The lower Cynicism (RC3) scale was also useful in differentiating social anxiety disorder. Other scales that were useful in distinguishing between pairs of groups were also identified.
Conclusion
: The results of this study suggest that the MMPI-2-RF scales can be useful for discriminat-ing anxiety disorders.
