ACL

Generalities

The Adjective Check List (ACL) was first created at the Institute of Personality Assessment and Research, now known as the Institute of Personality and Social Research (IPSR) in Berkeley, to assist staff members in describing the personalities of individuals examined in assessment programs. The ACL comprises of 112 items.

A study conducted by John (1990) involved a sample of 140 men and 140 women who had participated in groups of 10 to 15 in one of the IPSR assessment weekends. Each subject was described on the ACL by 10 staff members. A factor analysis was then performed using these aggregated observer judgments.
