The Jesness Inventory (JI) is a brief (155-item) true-false questionnaire with easy-to-understand items yielding 10 trait scores, an index of asocial tendencies, and nine personality subtype scales. Originally designed to assess youth between the ages of 8 and 19, the JI has been found to be useful with adults as well.
