This study investigated the usefulness of personality measures obtained during graduate training in predicting the scientist-practitioner behavior of counseling psychologists. Personality scale scores on the Self-Directed Search, Strong-Campbell Interest Inventory (General Occupational Theme scores), Minnesota Importance Questionnaire, Omnibus Personality Inventory, Tennessee Self-Concept Scale, and Minnesota Multiphasic Personality Inventory obtained during the students' 1st semester of graduate study were used as predictors. Scientist-practitioner orientation scores calculated for participants reflected their scientist-practitioner interests, preferred job, and publication record. Only scores on the Independence scale of the Minnesota Importance Questionnaire and on the Social Extroversion scale of the Omnibus Personality Inventory were statistically significant predictors of actual scientist-practitioner orientation.
