GAD: Development of Intolerance of Uncertainty Model and Contrast Avoidance Model

Abstract

Generalized Anxiety Disorder (GAD) is a mental disorder characterized by extreme and uncontrollable worry. Current studies emphasize the importance of the Contrast Avoidance Model (CAM) and the Intolerance of Uncertainty Model (IUM) in comprehending GAD. The reliability of IUM is supported by empirical evidence that Intolerance of Uncertainty (IU) has a direct impact on worry. Although long-term strategies are required, Cognitive Behavioural Therapy for IU (CBT-IU) has demonstrated promise in reducing symptoms of both IU and GAD. Attachment styles play a crucial role, with IU mediating the influence of early experiences on GAD. In the IUM framework, pathways involving Positive Beliefs about Worry (PBW) and Negative Problem Orientation (NPO) have been delineated. CAM predicts GAD independently of IU and exhibits distinct effects on fear and sadness. The impact of Contrast Avoidance (CA) in worry is proved by prior studies. Future studies can draw attention to the association between CA and other variables.
