Abstract
Studied the relationship between irrational beliefs and 15 psychological needs described by Murray. The Irrational Beliefs Test (IBT) and the Adjective Check List (ACL) were administered to 46 high school students and 50 adults. Results of stepwise multiple regression analyses indicated that five IBT scales and IBT Full-Scale were significantly associated with psychological needs. It was concluded that pathological behavior could not be readily predicted on the basis of irrational beliefs. It was further concluded that Ellis' model of personality obtained additional validating evidence.
