Vulnerability factors of generalized anxiety disorder based on triple vulnerability model

Triple vulnerability model focuses on the interaction of three types of vulnerabilities in development and maintenance of emotional disorders. Despite the prominence of this model, there is not enough research done to assess its experimental validity. The aim of this study was to evaluate vulnerability factors of generalized anxiety disorder based on triple vulnerability model.
For this purpose, 320 students from Tabriz University (Iran) were selected by cluster sampling and responses to NEO Five-Factor Inventory, Anxiety Control Questionnaire-revised, Intolerance of Uncertainty Scale and Generalized Anxiety Disorders Questionnaire-IV. Analysis was performed using structural equation modeling.
Evaluation of hypothetical model using fit indices showed that the hypothetical model fitted with the measurement model. The results showed that neuroticism and extroversion have significant effect on generalized anxiety disorder by mediation of lack of perceived control and intolerance of uncertainty. In addition, hypothetical model was a better fit in compare to the alternative models.
our result, along with the support of triple vulnerability model for generalized anxiety disorder, proposes a suitable framework for the etiology of this disorder
