Interparental conflict and children's sleep quality in the chinese family context: the serial mediating roles of emotional insecurity and subjective well-being.
Article in BMC psychology, 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
backgroundSleep problems in children are an important risk factor for cognitive, emotional, and behavioral development. Previous studies have shown that interparental conflict is closely associated with poorer sleep quality in children. However, the internal psychological variables involved in this association, particularly how they may be understood within the Chinese family context, remain insufficiently examined. Based on a sample of Chinese children, this study examined the association between interparental conflict and poorer sleep quality in children, and it tested the mediating pathways of emotional insecurity and subjective well-being(SWB).
methodsThis study employed a quantitatively driven explanatory sequential mixed-methods design combining questionnaire survey data with child interviews. The quantitative component included 900 upper-grade primary school children (M = 10.58, SD = 0.81). Correlation analyses and a serial mediation model were used to examine the associations among interparental conflict, emotional insecurity, SWB, and children's sleep quality. In the qualitative component, semi-structured interviews were conducted with 23 children, and thematic analysis was used to supplement and contextualize the quantitative findings.
resultsInterparental conflict was significantly associated with poorer sleep quality in children (r = 0.39, p < 0.001), and this association remained significant after emotional insecurity and SWB were included as mediators in the model (β = 0.11, p = 0.006). The statistical indirect effects through emotional insecurity, through SWB, and through emotional insecurity and SWB in sequence, were all significant, with effect values of 0.014, 0.019, and 0.004 respectively. The qualitative findings showed that the interviewed children incorporated interparental conflict into their understanding of family relationships, their own situations, and daily life circumstances. Within the Chinese family context, these responses were more clearly reflected in a contextualized organization of meaning around family harmony, parent-child connection, and relational responsibility.
conclusionsEmotional insecurity and SWB are important psychological variables for understanding the association between interparental conflict and poorer sleep quality in children. At the same time, these processes may acquire specific meanings within the Chinese family context.
