This chapter describes five contemporary psychological theories of generalized anxiety disorder (GAD). These models include the Avoidance Model of Worry and GAD, the Intolerance of Uncertainty Model, the Metacognitive Model, the Emotion Dysregulation Model, and the Acceptance-based Model of GAD. The five theoretical models are compared and contrasted, and the empirical evidence for each model is reviewed and critiqued. The efficacy and effectiveness of treatments based on these five models is then reviewed. The chapter closes with additional discussions concerning the mechanisms of change during treatment programs and the interaction between patient characteristics and treatment approaches.
