Intolerance of uncertainty (IU) is a disposition which develops from one’s beliefs about uncertainty and its consequences (Dugas & Robichaud, 2007). IU has long been part of cognitive models of generalized anxiety disorder (GAD: e.g. Dugas, Gagnon, Ladouceur, Freeston, 1998) and is also increasingly recognized 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).
Two categories of beliefs about uncertainty are believed to be clinically important: (1) beliefs that uncertainty has negative implications for oneself and one’s behavior, and (2) beliefs that uncertainty is unfair and spoils everything (Hebert & Dugas, 2018). The Uncertainty Beliefs – Experiment Record worksheet helps clients to identify these beliefs and to design behavioral experiments to address them.
The Uncertainty Beliefs – Experiment Record is grounded in cognitive-behavioral theory, aiming to:
For clients whose persistent worry is driven by beliefs that uncertainty is dangerous, intolerable, or must be eliminated.
To help clients test rigid beliefs about needing certainty or control in order to prevent feared outcomes.
Including social anxiety, panic disorder, or adjustment difficulties where beliefs about unpredictability contribute to avoidance or distress.
Pinpoint the client's most distressing belief about uncertainty.
Encourage discussion about the emotional and physiological responses to uncertainty.
Help design an experiment to test the client's belief in real-world scenarios.
Guide the client in executing the experiment, ensuring data collection and safety.
Discuss the outcomes and derive insights about the validity of the original belief.
Intolerance of uncertainty (IU) is dispositional tendency to find the experience of uncertainty distressing, and to respond with cognitive, emotional, and behavioral efforts to reduce or eliminate it. Rather than being a fear of specific negative outcomes, IU is an aversive response to the ambiguity or unpredictability of future events. This construct has been identified as a central feature of generalized anxiety disorder (Dugas et al., 1998; Dugas & Robichaud, 2007), and more recent research has highlighted its relevance across a range of psychological difficulties, including obsessive-compulsive disorder, depression, and eating disorders (Carleton et al., 2012; Renjan et al., 2016; Toffolo et al., 2014).
Research suggests that individuals high in IU hold unhelpful beliefs that amplify distress in the face of uncertainty. These beliefs often concern the perceived harmfulness of uncertainty - for example, that it impairs effective decision-making or leads to negative consequences - and may also reflect a sense that uncertainty is unfair, unacceptable, or something to be avoided at all costs (Hebert & Dugas, 2019). These beliefs contribute to excessive worry, reassurance-seeking, avoidance, and compulsive behaviors, all of which maintain distress over time and limit opportunities for adaptive learning.
The Uncertainty Beliefs – Experiment Record is designed to help clients examine and test these beliefs through structured experiential exercises. This approach encourages clients to confront uncertainty in real-world contexts and reflect on the results. By generating specific predictions and evaluating the outcomes of behavioral experiments, clients are given the opportunity to gather evidence about the validity of their beliefs and to consider alternative interpretations.
Therapists benefit from a clear, structured process that aligns with cognitive-behavioral frameworks, encouraging evidence-based practice.
