In two studies, one correlational (N = 158) and one experimental (N = 128), using college students, it was found that Need for Achievement, Need for Approval and Self-Downing were the most important irrational beliefs of the General Attitude and Belief Scale predicting unconditional self-acceptance. The Need for Comfort, Demand for Fairness and Other-Downing subscales were found to be less influential. The findings were discussed in terms of Ellis’ theoretical formulation of four higher-order types of irrational belief processes (demandingness, awfulizing, low-frustration tolerance and self-downing), empirical research on different irrational belief themes, the distinction between ego disturbance and discomfort disturbance in REBT and the distinction between sociotropy and autonomy in different forms of depression.
