Emotion Reactivity Moderates the Association Between Momentary Negative Affect and Suicidal Thinking.
Article in Brain and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMost theories suggest suicidal thinking results from negative affect, but surprisingly few studies have assessed factors that may modify the relationship between negative affect and suicidal intent. Emotion reactivity is an understudied element of affective experience that may affect this relationship.
methodsThis study examined ecological momentary assessment (EMA) data from two samples (n = 43 college students reporting suicidal ideation; n = 52 individuals with a history of suicide attempt recruited online) to investigate if trait emotion reactivity moderates the prediction of suicidal intent by negative affect. We hypothesized that increased trait emotion reactivity would strengthen the association between negative affect and next-timepoint suicidal intent.
resultsAs hypothesized, across both samples, results indicated the association between momentary negative affect and next-timepoint suicidal intent was stronger among those with greater trait emotion reactivity. Different facets of emotion reactivity appeared to drive these associations between studies (intensity in Study 1, and persistence and sensitivity in Study 2).
conclusionThese findings highlight the importance of including emotion reactivity in models of suicide and suggests trait-level patterns of emotional responses are important to consider when modeling associations with momentary suicidal thoughts and behaviors. Between-sample inconsistencies regarding which facets drove this relationship may speak to differences in emotional processing, which could hold important treatment implications.
