Intolerance Of Uncertainty
Intolerance of uncertainty can be viewed as a dispositional characteristic that results from a set of negative beliefs about uncertainty and its implications. (Dugas & Robichaud, 2007)
Intolerance of uncertainty involves the tendency to react negatively on an emotional, cognitive, and behavioral level to uncertain situations and events. (Dugas, Buhr, & Ladouceur, 2004)
Uncertainty is a normal part of life – we can never be 100% sure about what will happen next. Many people feel good about uncertainty and live lives where they seek excitement: they often score highly on personality measures of ‘openness to experience’. Other people find uncertainty aversive, stressful, or distressing, and don’t function as well in uncertain situations. They might hold negative beliefs about uncertainty and may try to avoid it, or use strategies to try to control or eliminate it. Psychologists label these reactions as ‘intolerance of uncertainty’. Commonly-used metaphors are that people who are intolerant of uncertainty are behave as though they have a phobia of uncertainty, or as though they are ‘allergic to uncertainty’.
Intolerance of uncertainty (IU) was first described in individuals suffering from Generalized Anxiety Disorder (GAD). Many behaviors associated with GAD, such as worry and avoidance, can be framed as attempts to increase ones sense of certainty: worry is the attempt to look ahead and foresee potentially negative consequences, avoidance and ‘sticking to what is known and safe’ reduces exposure to the unknown. More recent research has recognised intolerance of uncertainty as a transdiagnostic risk factor for many clinical conditions including anxiety, depression, obsessive-compulsive disorder, and eating disorders (Carleton et al, 2012; Toffolo et al, 2014; Renjan et al, 2016).
The Intolerance Of Uncertainty information handout describes IU in the context of worry, and outlines some of the unhelpful strategies that people high in IU tend to use to control how they feel. One important aspect of treatment for GAD is the effort to increase client’s willingness to tolerate uncertainty, sometimes framed as the challenge of ‘embracing uncertainty’.
