Abstract

 
Introduction: Generalized anxiety disorder (GAD) is taken into consideration more than ever in the past decade, by progress and development of many theories about "worry" as fundamental cognitive component in this disorder. Generalized anxiety disorder, as a chronic disorder, mostly occurs several years before depression. However, few studies have been conducted on the etiology and treatment of this disorder. This study aimed to investigate cognitive therapy model based on Dougas on intolerance of uncertainty, cognitive avoidance and positive beliefs about worry in patients with generalized anxiety disorder.
Method: In this study, single case experimental design with multiple baselines was used. The sample group included five patients with generalized anxiety disorder who were having inclusion and exclusion criteria. Sampling was conducted based on voluntary and convenience method. Diagnosis of Generalized Anxiety Disorder was done according to the Structured Clinical Interview (SCID-I) and clinical psychologist. Intolerance of uncertainty scale (IUS), Penn State Worry Questionnaire (PSWQ), Cognitive Avoidance Questionnaire (CAQ) and Why Worry Questionnaire (WWQ-II) were used as measures in the pre and post intervention. Effect size and cure rate were used to analyze data.
Results: The results showed that effect size in intolerance of uncertainty was 0.72, cognitive avoidance was 0.79 and a positive belief about worry was 0.66.
Conclusion: Results of this study indicates that cognitive therapy model based on Dougas has positive effect on intolerance of uncertainty, cognitive avoidance and positive beliefs about worry and lead to reduce them. Also this treatment besides of pharmacotherapy could be used as one of effective options in reducing GAD symptoms.
