Dysfunctional cognitions and insomnia symptoms in pregnant women: the serial mediation roles of pre-sleep arousal and maladaptive habits.
Article in BMC psychiatry, 2025. 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
objectiveInsomnia is prevalent among pregnant women and adversely affects maternal and fetal health. The mechanisms that underpin the relation between sleep-related cognitions and insomnia symptoms among pregnant women are unclear. This study tried to examine the mediation roles of pre-sleep arousal and maladaptive habits between dysfunctional cognitions and insomnia symptoms during pregnancy.
methodsPregnant women (N = 450) from two tertiary hospitals in Yangzhou, Jiangsu Province, China, were recruited. Participants completed self-report measures, including the Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16), Pre-Sleep Arousal Scale (PSAS), Sleep Hygiene Practice Scale (SHPS), and Insomnia Severity Index (ISI). Pearson correlation was tested and serial multiple mediation analysis was conducted using Hayes’ PROCESS macro.
resultsDysfunctional cognition, pre-sleep arousal, maladaptive habits, and insomnia symptom scores were all significantly correlated with each other (all P < 0.01). Pre-sleep arousal (B = -0.060, 95%CI: -0.082, -0.040) and maladaptive habits (B = -0.021, 95%CI: -0.036, -0.010) significantly mediated the relation between dysfunctional cognitions and insomnia symptoms, accounting for 37.74% and 13.21% of the total effect, respectively. The serial multiple mediating effects of pre-sleep arousal and maladaptive habits (B = -0.020, 95%CI: -0.028, -0.012) in the association between dysfunctional cognitions and insomnia symptoms explained 12.58% of the total effect. These findings indicate that dysfunctional cognitions contribute to insomnia symptoms not only directly but also indirectly through elevated arousal and poor sleep practices, which operate both independently and in sequence.
conclusionsPre-sleep arousal and maladaptive habits play serial mediating roles in the relation between dysfunctional cognitions and insomnia symptoms among pregnant women. Development of targeted interventions addressing the cognitive and behavioral factors contributing to insomnia symptoms in pregnant women is needed. CLINICAL TRIAL NUMBER: Not applicable.
