Cognitive and emotional traits as mediators in the relationship between family factors and obsessive-compulsive disorder in adolescents.
Article in BMC psychiatry, 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
backgroundObsessive-compulsive disorder (OCD) is a multifaceted psychiatric disease requiring more in-depth mechanism research to improve treatment outcomes, with family-related variables playing a crucial role, particularly in adolescent populations.
methodsA total of 113 adolescents with OCD were included in this study. All patients were assessed by the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Family Environment Scale (FES), Parenting Style Assessment Scale (EMBU), Obsessive Beliefs Questionnaire (OBQ-44) and State-Trait Anxiety Inventory (STAI). The correlation between family factors (dysfunctional family environment and negative parent rearing), cognitive traits (obsessive beliefs), emotional traits (anxiety traits), and obsessive-compulsive symptoms (OCS) were analyzed. Moreover, the mediating effect of cognitive and emotional traits between family factors and OCS was explored. Finally, 31 parents of patients and 20 non-clinical adolescents and their parents completed the FES, EMBU, OBQ-44, and STAI.
resultsThe results showed that dysfunctional family environment, negative parent rearing, obsessive beliefs and anxiety traits were positively correlated with OCS in adolescents with OCD. Parallel mediation analyses revealed that obsessive beliefs fully mediated the relationship between family factors and OCS, whereas anxiety traits did not show a significant unique mediating effect after controlling for obsessive beliefs. Compared with parents of non-clinical adolescents, parents of OCD patients showed significant obsessive beliefs and anxiety traits.
conclusionCognitive traits (obsessive beliefs), but not emotional traits (anxiety traits), served as a unique mediating mechanism between family factors and OCS. Both cognitive and emotional traits demonstrated familial aggregation. These findings provide an empirical basis for family-based interventions targeting obsessive beliefs in adolescents with OCD.
