The Relationship between Anger and Irrational Beliefs and their Effect on Aggression in a Sample of Lebanese Youth between the Ages of 18 and 25 (SBS thesis, Haigazian University)https://doi.org/10.62811/th.0223https://haigrepository.haigazian.edu.lb/handle/123456789/268The aim of this study was to identify whether anger and irrational beliefs predict aggression in a sample of Lebanese emerging adults. The study was quantitative one based on a survey design applying linear and hierarchical regression analyses and t-test to examine the proposed hypotheses. A purposeful convenient sample of 148 Lebanese individuals between the ages of 18 and 25 completed online questionnaires including a Demographic Scale, Aggression Questionnaire, and the Shortened General Attitude and Belief Scale. Results revealed that anger and total irrational beliefs predict indirect aggression, anger and demand for fairness predict indirect aggression, anger, level of education, and self-dawning predict verbal aggression, and anger predicts physical aggression; moreover both male and female Lebanese emerging adults show similar levels of anger, but males show higher levels of physical and verbal aggression.. These findings are important in the conceptualization of the role of cognitions and emotions in differential aggressive behaviors. These findings suggest that Rational Emotional Behavioral Therapy is effective in the treatment of physical and indirect aggression while anger management is effective in the treatment of verbal aggression.
