Adjective Check List

The Adjective Check List (ACL) is an assessment used to identify common psychological traits. Developed by Harrison G. Gough and Alfred B. Heilbrun, Jr., the checklist contains 300 adjectives (such as intelligent, cautious, clear-thinking, determined, and poised). Respondents select the adjectives that they believe describe themselves (or someone else). The assessment may be administered to an individual, or used by researchers to describe study participants.
