This workshop will discuss the clinical application of CBT-targeting intolerance of uncertainty for GAD, with a focus on targeting indecisiveness. It will include: 1) presentation of the CBT-IU model for GAD; 2) review of behavioural experiments targeting IU; 3) presentation of decision-making styles and their influence on how people approach daily life decisions; 4) the impact of cognitive dissonance on decision-making; 5) safety behaviours for decisional worries, and the unique goals of “straddling the line” and “controlled spontaneity” when developing behavioural experiments. Specific examples of decision-making worries and how to target them will be provided.
