Further Validation for a New Measure of Irrational Cognitions

A test of commonly held irrational beliefs, postulated by Albert Ellis to contribute to psychopathology, was devised by Jones (1969) for research and clinical use. A previously published study by the authors (1972) provides support for the validity of the instrument. Additional data from that study bearing on the reliability and construct validity of the Irrational Beliefs Test are presented here and discussed. The instrument is viewed as having value for measuring cognitive aspects of psychopathology and psychotherapeutic change.
