My research centers on problems in construction and validation of psychological assessments, particularly those involving the assessment of personality and psychopathology. Recent scale construction projects have included the development and validation of MMPI-2 scales used to: (1) screen for substance abuse problems, (2) identify symptoms associated with Attention Deficit Hyperactivity Disorder, and (3) assess features of the Korean culture-bound syndrome of Hwa-Byung. Recent validation studies include examinations of: (1) the relative validity of commercially available computer-based test interpretations, (2) the utility of the MMPI-2 PSY-5 scales as measures of dispositional coping, and (3) the field reliability of clinical MMPI-2 interpretation. Many of my current projects apply a novel q-sort methodology to validate personality test inferences.
