My research centers construction and validation of psychological assessments, particularly involving the MMPI instruments. Recently published projects involve the use of the MMPI instruments to:

  1. identify prescription stimulant misuse,
  2. examine cross-cultural differences in psychopathology, and
  3. evaluate psychological difficulties among juvenile offenders.

Current projects include:

  1. development of an informant measure to complement the MMPI instruments,
  2. an evaluation of impairment associated with low levels of impulsivity, and
  3. examination of a gratitude intervention with Police Department support personnel.

Many of my research projects apply a novel q-sort methodology to validate personality test inferences. Please review my ResearchGate page for a more comprehensive account of research interests.
