The Effect of Intolerance of Uncertainty on Indecisiveness in Anxiety and Obsessive-Compulsive Disorders.
Trial report in Journal of clinical psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesIntolerance of uncertainty (IU) describes a dispositional aversion to uncertainty. Recent research has identified IU as a causal contributor to pervasive decision difficulties (indecisiveness). Given that IU and indecisiveness occur across mental disorders, understanding whether IU's causal role in indecisiveness extends to clinical populations is critical. This study therefore tested the effect of IU on indecisiveness in a clinical sample.
methodsIn this pre-registered experiment, N = 154 individuals with formally diagnosed obsessive-compulsive and/or anxiety disorders were randomly assigned to a condition aimed at either increasing or decreasing IU. Subsequently, participants reported their current levels of (situational) IU and their indecisiveness regarding two personally relevant decisions.
resultsWhile the manipulation had no main effect on indecisiveness, it influenced situational IU levels, which were positively associated with indecisiveness. Mediation analysis indicated a significant indirect effect of the experimental condition on indecisiveness via situational IU. LIMITATIONS: Compared to preceding research, effect sizes were small and the effect of IU on indecisiveness only manifested itself indirectly. More robust interventions may be necessary to induce more pronounced changes in IU within clinical populations. The reliance on a heterogeneous sample with various diagnoses limits the disorder-specificity of the findings.
conclusionsThese results tentatively extend the causal role of IU in indecisiveness to mental disorders. The findings suggest IU as a potential approach for addressing clinically relevant indecisiveness if future research corroborates the evidence.
