Abstract
The purpose of the present study was to develop an alternative paradigm for measuring irrationality and conduct a preliminary reliability and validity analysis of a self-report scale so constructed. From considering some basic theoretical assumptions in Rational-Emotive Therapy (RET), anemotive paradigm for item-construction was formulated and utilized to develop a 12-item self-report scale for measuring irrationality (SVO-12). A different scale (SVC-12), based on acontent approach, was also developed. These two irrationality scales and a scale for measuring psychopathology were then administered to a group of 199 undergraduate students. Statistical analyses provided empirical support for the reliability and validity of both approaches. Of the two irrationality scales in question, however, the one based on the emotive paradigm (SVO-12) seem to be the most promising.
