Exploring the role of interoception in anxious traits and symptoms.

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
Introduction: Interoception, the ability to sense internal bodily signals, has been increasingly linked to anxiety, yet the mechanisms underlying this relationship remain largely unknown. This study explored the associations between multiple dimensions of interoception and anxiety-related traits and symptoms in a non-clinical adult sample. Methods: A total of 305 participants completed self-report measures assessing interoceptive beliefs, attention, and perceived interoceptive accuracy, alongside measures of anxiety-related traits and symptoms. A subsample (n = 103) additionally completed laboratory-based heartbeat perception tasks to assess interoceptive accuracy, confidence, and insight via heartbeat counting and detection tasks.. Results: Correlational analyses revealed that anxiety-related traits were significantly associated with self-reported interoceptive difficulties. Novel associations between intolerance of uncertainty and interoception were observed, including negative correlations with interoceptive insight, bodily trust, and increased tendency to worry about discomforting internal sensations. Anxiety symptom severity was linked to self-reported increased attention to bodily signals, reduced bodily trust, and lower perceived accuracy. However, no significant relationships were observed between the heartbeat perception task measures and anxiety-related traits, symptoms, or self-reported interoceptive abilities.. Discussion: Findings support the conceptualisation of interoception as a multidimensional construct, demonstrating interoceptive accuracy and interoceptive beliefs as distinct constructs. Results align with emerging evidence that anxious traits are more closely related to subjective beliefs and interpretations of bodily signal than to behavioural interoceptive accuracy. These findings contribute to theoretical models of anxiety by highlighting interoceptive beliefs and attentional processes, rather than accuracy, as key factors warranting further investigation in clinical contexts.
