On September 22nd 2023, Dr. Melisa Robichaud will deliver a half-day workshop on behavioural experiments for excessive worry and GAD, with an emphasis on targeting the fear of uncertainty and its consequences.

Workshop Outline

Excessive worry is a symptom present across most anxiety disorders, and it is also the cardinal feature of generalized anxiety disorder (GAD). Yet despite its omnipresence in anxiety, excessive worry can be challenging to address in treatment, particularly with individuals struggling with GAD. A primary reason for this is that the content of worry can often be varied and shifting in nature, such that traditional CBT strategies that target the worries themselves can often feel like they involve “chasing a moving target”. It can therefore be more helpful to conceptualize excessive worries and GAD according to the processes that underlie them, rather than on the symptom of worry itself. This workshop will focus on the process-driven understanding and treatment of excessive worry and GAD as a cognitive response to the perceived threat of uncertainty and its consequences on outcomes and personal coping due to an overall intolerance to uncertainty. 

This workshop will present clinical strategies designed to conceptualize and treat excessive worry seen in GAD and other anxiety disorders through the lens of the construct of intolerance of uncertainty (IU). Specifically, the role of IU as the primary theme of threat in GAD and excessive worry will be introduced, with an emphasis on presenting a cohesive and logical rationale to clients. In addition, the development, application, and debriefing of behavioural experiments designed to specifically challenge negative beliefs about uncertainty will be presented. Specific examples of worry themes will also be reviewed, including worries related to decision-making, perfectionism, and a need for control. Case vignettes, as well as detailed homework handouts and examples, will be included throughout.

Learning Objectives

At the end of the session, attendees will learn to:

  • Understand and conceptualize excessive worry and GAD within a CBT framework that highlights the role of intolerance of uncertainty

  • Present a clinical model of excessive worry to clients that uses the fear of uncertainty as the primary theme of threat

  • Identify worry-specific safety behaviours

  • Develop behavioural experiments designed to test out negative beliefs about uncertainty and its consequences

  • Troubleshoot challenging presentations, including worries related to perfectionism, indecisiveness, and need for control
