Emotion regulation and depressive symptoms mediate the association between chronotype and suicidality.

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
objectiveEmotion regulation, while closely linked to depressive symptoms, has seldom been examined together with them in studies of the relationship between chronotype and suicidality. We therefore examined whether chronotype predicts suicidality through the sequential mediation of poor emotion regulation and depressive symptoms. In addition, we examined whether these mediation pathways differ between morning-type and evening-type groups.
methodsThis study included 3109 Korean adults from the general population. Chronotype, depressive symptoms, emotion regulation, and suicidality were assessed using the Composite Scale of Morningness, Self-Rating Depression Scale, Emotion Regulation Skills Questionnaire, and the Suicidality module of the Mini International Neuropsychiatric Interview, respectively.
resultsChronotype did not have a direct effect on suicidality. Instead, eveningness was indirectly linked to higher suicidality. Specifically, individuals with stronger eveningness tendencies reported poorer emotion regulation, which increased depressive symptoms; depressive symptoms, in turn, predicted suicidal ideation, which emerged as a significant predictor of suicide attempts. Subgroup analyses revealed that the same sequential pathway was significant only among evening-types, but not among morning-types.
conclusionsChronotype appears to play a role in suicide risk in the general population. Screening for chronotype and focusing on emotion regulation and depressive symptoms may enhance prevention efforts tailored to chronotype, especially for evening-type individuals.
