Irrational beliefs in major depression and generalized anxiety disorders in an Iranian sample: a preliminary study

Previous research on Rational Emotive Theory using western samples has shown that irrational belief systems are associated with emotional disorders such as anxiety and depression. In a replication of this work the present study was conducted to compare the scores of 29 clinically depressed, 31 clinically anxious, and 34 normal controls on the Irrational Beliefs Test in an Iranian sample. Consistent with Ellis's theory, depressed and anxious patients scored higher than the controls on scores for the full scale and all 10 subscales of the Irrational Beliefs Test. Also, the two patient groups differed significantly in their endorsement of 2 out of 10 irrational belief subscales but not in overall score on irrational beliefs. Results were interpreted in light of previous literature.     

Psychometric Properties of the Survey of Personal Beliefs: A Rational-Emotive Measure of Irrational Thinking

A test of internal consistency and confirmatory factor analyses were performed on the Survey of Personal Beliefs, a new measure of irrational thinking based on rational-emotive personality theory. The survey, which was logically derived, includes a general rationality factor and subscales measuring five hypothesized core categories of irrational beliefs. Subjects included a nonclinical sample of 130 men and 150 women, with a mean age of 46. Results indicated that the Survey of Personal Beliefs had satisfactory total and scale reliability. The confirmatory analyses supported a higher order factor model including 5 first-order factors (awfulizing, self-directed shoulds, other-directed shoulds, low-frustration tolerance, and self-worth) and 1 second-order or general factor.

Perfectionism,Distress, and Irrational Beliefs in High School Students: Analyses with an Abbreviated Survey of Personal Beliefs for Adolescents

The current study examined the associations between dimensions of perfectionism and irrational beliefs in an adolescent sample. In addition, we tested the association between psychological distress and irrational beliefs in adolescents and we evaluated the feasibility of creating a modified version of the Survey of Personal Beliefs for use with adolescents. A sample of 250 adolescents (108 males, 142 females) completed the Child-Adolescent Perfectionism Scale, the Survey of Personal Beliefs, and the CES-D Depression Scale. Initial psychometric analyses yielded an abbreviated 30-item Survey of Personal Beliefs with adequate internal consistency for four of the five subscales. Our results showed that self-oriented perfectionism was associated significantly with all five irrational belief subscales, while the associations between socially prescribed perfectionism and irrational belief subscales were much smaller in magnitude. Self-oriented perfectionism, socially prescribed perfectionism, and irrational beliefs were all associated significantly with elevated distress among adolescents, and irrational beliefs predicted unique variance in distress, over and above the variance attributable to the trait perfectionism dimensions. The findings confirmed the association between perfectionism and irrational beliefs and their respective roles in psychological distress among adolescents.     

Adrenal hormone excretion and irrational thinking

Stress reactions to irrational thinking were assessed by studying the relationships between adrenal hormone levels and various psychological scales and indicators of stress symptoms. Of the psychological tests, the Jones Irrational Beliefs Test correlated significantly (negatively) with noradrenaline level. Further, both noradrenaline and adrenaline levels were strongly predicted by physiological variables and irrational beliefs.     

Body dissatisfaction and irrational beliefs

To test the hypothesis that the irrational evaluative beliefs, postulated by Rational-Emotive Behavior Therapy, are associated with body dissatisfaction, 94 women (21 diagnosed with an eating disorder, 38 with high body dissatisfaction but without an eating disorder, and 35 with low body dissatisfaction) completed the Survey of Personal Beliefs and the Eating Disorders Inventory. Analysis showed no significant difference in body dissatisfaction between the Eating Disordered and High Body Dissatisfaction subgroups. No significant correlations between body dissatisfaction and irrational beliefs were found for the Eating Disordered subgroup. For the High Body Dissatisfaction subgroup, significant but low correlations were found between scores on body dissatisfaction and irrational standards for self and others and with negative self-rating. In terms of irrational beliefs the Eating Disordered and High Body Dissatisfaction subgroups showed a significantly greater tendency towards Catastrophizing, Low Frustration Tolerance, and Negative self-rating, compared to the controls, without any significant difference between the former two groups. The Eating Disordered subgroup but not the High Body Dissatisfaction subgroup differed significantly from the controls in terms of more Self-directed demands.     

Relation of irrational thinking and the Pessimistic Explanatory Style

This study investigated the possible relationship between Ellis's construct of irrational thinking and Seligman's construct of explanatory style, with a view toward possibly strengthening the personality theory underlying Rational Emotive Behavior Therapy in particular and cognitive-behavior therapies more generally. In this investigation 180 college students were administered the Survey of Personal Beliefs and the Attributional Style Questionnaire to measure irrational thinking and explanatory style, respectively. Students who scored higher on Pessimistic Explanatory Style also scored higher on Overall Irrational Thinking and on Low Frustration Tolerance than did those who were categorized as having an Optimistic Explanatory Style. This indicates support for Ellis's developing personality theory, especially his theoretical account of depression.     

Dimensions of perfectionism and irrational thinking

Several authors have suggested that perfectionism is associated with irrational thinking. The purpose of the present research was to test the hypothesis that various dimensions of perfectionism are related significantly to core irrational beliefs. In Study 1, 102 subjects completed the Multidimensional Perfectionism Scale (MPS) and the Irrational Beliefs Test (IBT). The MPS provides assessments of self-oriented, other-oriented, and socially prescribed perfectionism. Analyses revealed that self-oriented perfectionism was correlated positively with the IBT high self-expectations and perfect solutions subscales. Socially prescribed perfectionism was correlated significantly with a variety of irrational beliefs including high self-expectations, demand for social approval, dependency, blame proneness, and anxious overconcern. Other-oriented perfectionism was correlated with few irrational beliefs. In Study 2, 130 subjects completed the MPS and the Survey of Personal Beliefs, a new measure of core irrational beliefs. Analyses confirmed that all three perfectionism dimensions were associated with core irrational beliefs. It is concluded that the results constitute general support for the hypothesis that cognitive aspects are important in both personal and social components of perfectionism and that perfectionists are characterized by increased levels of irrational beliefs that may contribute to maladjustment. The findings are discussed in terms of the associations among perfectionism, irrational beliefs, and maladjustment.Gordon L.

IRRATIONAL BELIEFS AND SOCIAL CONSTRUCTIONISM: CORRELATIONS WITH ATTITUDES ABOUT REALITY,BELIEFS ABOUT PEOPLE,AND COLLECTIVE SELF-ESTEEM

Rational Emotive Behavior Therapy (REBT) is theoretically consistent with the postmodern social constructionist assumption of a reciprocal causality between the individual and society. In a test of this claim, REBT irrationalities as measured by the Irrational Belief Scale and by the Survey of Personal Beliefs were correlated with Attitudes toward Reality, Cynicism, Beliefs in the Conventional Goodness of People, and Collective Self-Esteem. All measures of irrationality identified the postmodern social constructionism recorded by the Attitudes toward Reality Scale as rational. Especially the Irrational Belief Scale identified Cynicism and Beliefs in the Conventional Goodness of People as irrational and Collective Self-Esteem as rational. The Survey of Personal Beliefs described Collective Self-Esteem as irrational and therefore suggested that the conceptual framework of REBT can promote negative assessments of collectivistic forms of adjustment. Most importantly, however, these data confirmed that REBT includes potentials that are compatible with postmodern social constructionism. Address correspondence to P. J.

The Irrational Beliefs Inventory: Cross Cultural Comparisons Between American and Dutch Samples

The 50-item Irrational Beliefs Inventory (IBI) was developed in the Netherlands for the assessment of irrational thinking. The IBI was derived from the Rational Behavior Inventory (RBI) and the Irrational Beliefs Test (IBT). The present study was designed to assess the applicability of the IBI in a different cultural context. The IBI was administered to a non-clinical sample in the USA; scores were consistent with Dutch findings and support the utility of the English language version of the IBI.     

A test of the ABC model underlying rational emotive behavior therapy

The ABC model underlying Ellis's Rational Emotive Behavior Therapy predicts that people who think more irrationally should respond to daily stressors or hassles differently than do people who think less irrationally. This study tested this aspect of the ABC model. 192 college students were administered the Survey of Personal Beliefs and the Hassles Scale to measure irrational thinking and daily hassles, respectively. Students who scored higher on overall irrational thinking reported a significantly higher frequency of hassles than did those who scored lower on overall irrational thinking, while students who scored higher on awfulizing and low frustration tolerance reported a significantly greater intensity of hassles than did those who scored lower on awfulizing and low frustration tolerance. This indicates support for the ABC model, especially Ellis's construct of irrational beliefs central to this model.     

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.     

Use of the Survey of Personal Beliefs Scale: Further validation of a measure of irrational beliefs with psychiatric inpatients

Development of valid instruments for measuring underlying irrational beliefs is necessary for ongoing research of Rational-Emotive Therapy (RET). This study was designed to further evaluate the validity of one such measure, the Survey of Personal Beliefs (SPB). Adult psychiatric inpatients completed the SPB and measures of depression, hopelessness, and anxiety, as well as a conceptually similar measure of irrational thinking, the Belief Scale. It was predicted that if construct validity exists for the SPB then a significant correlation would exist between irrational beliefs as measured by the SPB and depression, hopelessness, and anxiety. It was also predicted that if the scale has construct validity, then patients being treated with RET would demonstrate a greater reduction in irrational thinking based on SPB scores than would inpatients receiving treatment not based on RET. To evaluate for discriminate validity, it was predicted that the SPB would correlate more highly with a conceptually similar measure of irrational thinking than with measures of depression, hopelessness, and anxiety. The findings of this study offer support for the validity of the SPB. Additional and unexpected findings as well as recommendations are discussed.Dr. Nottingham is an Associate Fellow and Approved Supervisor of the Institute for Rational-Emotive Therapy.

Alexithymia, Irrational Beliefs, and the Rational-Emotive Explanation of Emotional Disturbance

In recent discussions of Rational-Emotive Behavior Therapy (REBT), Ellis has argued that unconscious processes supplement irrational beliefs in explaining psychopathology. The hypothesis of this investigation was that these unconscious processes reflect alexithymia. University students responded to the three factors from the Toronto Alexithymia Scale, the Malouff and Schutte Belief Scale (MSBS), 5 subscales from the Survey of Personal Beliefs, and instruments recording depression, anxiety, and neuroticism. As hypothesized, alexithymia and irrational beliefs predicted greater emotional disturbance while also displaying some small positive correlations with each other. In multiple regressions, both types of variables combined to predict emotional disturbance, with alexithymia explaining the greater amount of variance. Alexithymic difficulties in identifying emotions had uniquely negative mental health implications. The MSBS and the Low Frustration Tolerance subscale were the most noteworthy measures of a pathogenic irrationality. These data supported the claim that the unconscious processes of REBT could be conceptualized in terms of alexithymia.     

The relationships among the general attitude and belief scale,other dysfunctional cognition measures,and depressive or bulimic tendencies

This study assessed the relationships between the General Attitude and Belief Scale (GABS) and measures of 1) irrational beliefs derived from Ellis' older and newer theorizing, 2) reasoning errors based on Beck's theory, and 3) affective and behavioral disorder, specifically depression and bulimia. Female undergraduates (n=160) completed the GABS, Irrational Beliefs Scale, Irrational Beliefs Test, Rational Behaviors Inventory, Dysfunctional Attitude Scale, Cognitive Error Questionnaire and the Beck Depression Inventory, Center for Epidemiologic Studies — Depression Scale, and Bulimia Test. Results supported the internal consistency and construct validity of the GABS; progressively higher correlations were obtained with measures more similar to the GABS theoretically.Dr. Eleanor H.

Empirical Investigation of the Relationships Between Irrationality,Self-Acceptance,and Dispositional Forgiveness

Milburn (J Ration Emot Cogn Behav Ther 33:325–340, 2015) recently suggested a theoretical link between REBT and forgiving, proposing that irrational beliefs, particularly demandingness and global evaluations of human worth, play a role in lack of forgiveness. The present study investigated a quantitative link between the concepts of irrationality, self-acceptance, and dispositional forgiveness. Four-hundred and thirty-three participants (70% female) participated in a 69-item online survey combining four previously validated scales: Shortened General Attitude and Belief Scale; Heartland Forgiveness Scale; Unconditional Self-Acceptance Questionnaire; and the Transgression Narrative Test of Forgivingness—(with revised response-options). Results indicated moderate and strong negative correlations between irrationality and dispositional forgiveness. Conversely, unconditional self-acceptance was significantly positively correlated with dispositional forgiveness. Regression analyses indicated that subtypes of irrationality and self-acceptance could predict dispositional forgiveness of self, other, and situation. No significant differences were found between sexes. These findings add empirical support to the hypotheses made by Milburn, suggesting that holding irrational beliefs impedes the process of forgiving, and one’s level of self-acceptance predicts one’s disposition to forgive.     

Irrational Beliefs, Interpersonal Perception and Marital Adjustment

To test the hypothesis that the major evaluative beliefs postulated by Rational-Emotive Behaviour Therapy are related to marital adjustment, 50 married couples completed the Dyadic Adjustment Scale (DAS) and the Survey of Personal Beliefs (SPB). Significant correlations were found between DAS scores and three subscales (Other directed shoulds, Low frustration tolerance and Self worth) of the SPB. On the interpersonal dimension of assumed similarity, females in the high dyadic adjustment group were better able to predict their spouses' awfulizing, low frustration tolerance and self-worth beliefs than were females in the low adjustment group. However, the present study offers only limited support for the hypothesis that interpersonal perception of irrational evaluative beliefs is related to marital adjustment.     

Sex-role related personality traits and irrationality

Among undergraduate psychology students, masculinity and femininity scores on the Personal Attributes Questionnaire were correlated with a measure of irrational value orientation. Both for women and men significant negative correlations between masculinity and irrationality were found. Feminity and irrationality proved to be unrelated in both sex groups. Finally, no interaction effect of masculinity and feminity on irrationality was obtained.     

Academic procrastination and irrational thinking: a re-examination with context controlled

As a test of the theory that academic procrastination is due to irrational thinking, undergraduate students at two universities were given the Procrastination Assessment Scale for Students (PASS), a measure of academic procrastination, and the Irrational Beliefs Inventory (IBI), an improved measure of irrational thinking. Because earlier research in this area had not adequately controlled for context effects (Council, 1993), the measures were administered at 2–3 week intervals as if they were separate research projects. Self-reported procrastination correlated with both a global measure of irrational thinking and with the subscale of problem avoidance. Implications for procrastination intervention strategies are discussed.
