Irrational Beliefs and Unconditional Self-Acceptance. II. Experimental Evidence for a Causal Link between Two Key Features of REBT

In a test of two key features of REBT, causal relationships between irrational beliefs and unconditional self-acceptance were experimentally investigated in a sample of 106 non-clinical participants using a priming technique. Priming participants with statements of irrational belief resulted in a decrease in unconditional self-acceptance whereas priming participants with statements of rational belief resulted in an increase in unconditional self-acceptance. In contrast, priming participants with statements about unconditional self-acceptance did not result in an increase in rational thinking and priming participants with statements about conditional self-acceptance did not result in an increase in irrational thinking. The present study is the first to provide evidence of a causal link between rational/irrational thinking and unconditional/conditional self-acceptance. The findings have important implications for the core hypothesis of REBT and underscore the advantages of experimental over correlational studies in theory-testing.     

Irrational Beliefs and Unconditional Self-Acceptance. III. The Relative Importance of Different Types of Irrational Belief

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.     

An experimental test of a core REBT hypothesis: evidence that irrational beliefs lead to physiological as well as psychological arousal

While numerous studies support Rational Emotive Behavior Therapy and Theory (REBT), they tend to be limited by their use of correlational designs, simulated scenarios and self-report measures. This study tested a core REBT hypothesis in an experimental design using multiple physiological as well as psychological measures. Ninety patients from a medical practice were placed in a real-life stressful situation while holding either a rational, an irrational, or an indifference belief. Those holding a rational belief reported the greatest increase in concern whereas those holding an irrational belief reported the greatest increase in anxiety. Of particular significance, those holding a rational belief showed a decrease in systolic blood pressure whereas those holding an irrational belief showed an increase (diastolic blood pressure increased in both conditions). These results not only support the core REBT hypothesis, but also suggest a way to differentiate between beliefs and emotions by measuring physiological as well as psychological changes.     

Irrational Beliefs as Predictors of Emotional Adjustment after Divorce

The goal of this study was to analyze the role of irrational beliefs and other mediating variables in emotional adjustment after marital separation. Self-esteem and attachment to the ex-spouse were chosen as indicators of emotional adjustment. For this purpose several mediation centres and associations for separated people took part in the project. The results showed that irrational beliefs, as well as length of conflict during marriage, time since divorce and desire of contact with the former spouse, are good predictors of emotional adjustment. It has been suggested that Rational-Emotive-Behavior Therapy can be used in the treatment of divorced people.
