Factor structure of the Smith irrational beliefs inventory: results of analyses on six independent samples

This study reports the results of six factor analyses (alpha factoring, direct oblimin rotation, Delta= .4) on six items from the Smith Irrational Beliefs Inventory. Six independent samples of 1851 college students (521 men, 1,280 women, 50 sex unstated) were tested. Three factors emerged with identical content for each analysis. Distorted Egocentrism was defined by two items reflecting feelings of entitlement and the naive assumption that events should always turn out favorably the way one desires; Task Exaggeration/Catastrophizing was defined by two items directly depicting a tendency to view challenges as overwhelming and catastrophic; and Isolated Low Self-esteem was defined by two items expressing the feeling that one has unacceptable feelings that could lead to isolation or rejection. Previous research on other irrational belief inventories has yielded inconsistent results, with multifactorial solutions emerging for clinical samples and unifactoral solutions for student samples. That the present six factor analytic studies yielded a consistent multifactoral set of irrational beliefs for a very large student sample suggests that factors do emerge when items are initially screened and the subject population is carefully defined.
