The Effect of Childhood Maltreatment on Affect Labeling in Youth: An ERP Study.

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
backgroundPrevious studies on emotional processing in individuals with a history of childhood maltreatment have primarily examined either implicit or explicit processing modes in isolation, with limited research integrating both approaches. Empirical evidence regarding the use of affect labeling to regulate emotions among young adults with childhood maltreatment remains lacking. The affect labeling paradigm used in this study incorporates both implicit and explicit processing mechanisms, thereby offering a comprehensive means to investigate how childhood maltreatment specifically influences emotional processing.
methodThis study employed event-related potential (ERP) techniques to examine the influence of maltreatment on the affect labeling effect, using both affect labeling and gender labeling tasks. Participants were classified into maltreated (n = 17) and non-maltreated (n = 19) groups based on their scores on the Childhood Trauma Questionnaire-Short Form (CTQ-SF).
results(1) At Cz and CPz, the LPP amplitudes induced by affect labeling were significantly smaller than those induced by gender labeling. (2) At Fz, FCz, Cz, CPz, and Pz, maltreated individuals exhibited significantly lower LPP amplitudes compared to non-maltreated individuals. (3) With respect to emotional categories, the LPP amplitudes in response to happy faces were smaller than those to angry faces.
conclusionThe findings suggest that implicit emotion regulation is beneficial for young adults with a history of childhood maltreatment in terms of emotion management. Maltreated individuals demonstrated decreased emotional arousal across both implicit and explicit emotional tasks, confirming the influence of maltreatment on the affect labeling effect. This supports the disruption theory. The present study expands the application of the affect labeling effect and provides new electrophysiological evidence for research on cognitive changes in individuals with childhood maltreatment.
