Introduction & Theoretical Background
Intolerance of uncertainty (IU) is a disposition – or character trait – which develops from one’s beliefs about uncertainty and its consequences (Dugas & Robichaud, 2007). Some people have a positive attitude towards uncertainty (“It’s boring to always know what’s going to happen”, “I like to trust my intuition and go with the flow”) whereas people who have high IU tend to have more negative beliefs about uncertainty (e.g. “It’s unbearable not knowing”, “Uncertainty ruins everything”) and may find it hard to tolerate even a small amount of uncertainty.
Intolerance of uncertainty has long been part of cognitive models of generalized anxiety disorder (GAD: e.g. Dugas, Gagnon, Ladouceur, Freeston, 1998) and there is a strong relationship between IU and GAD (e.g. Donegan et al, 2010; Dugas & Ladouceur, 2000). It is also increasingly recognized as a transdiagnostic risk factor for many clinical conditions, including anxiety, depression, obsessive-compulsive disorder, and eating
Therapist Guidance
“People sometimes react strongly to uncertainty because of what they believe about it. While some people are OK with uncertainty and ‘not knowing’, for other people it is almost as though they are allergic to uncertainty – even a small amount can cause a powerful reaction. People who are ‘allergic to uncertainty’ often spend a lot of time trying to avoid it, either by worrying about what might happen, or by thinking of coping strategies for uncertain situations they can’t avoid. Can you relate to this? The problem is that these ‘solutions’ to uncertainty come with their own costs. This exercise is designed to help you to explore some of your beliefs about uncertainty – would you be willing to do that with me?”
