Latent profile analysis of obsessive-compulsive symptoms and its relationship with the Big Five Personality Inventory among college students.
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
objectiveTo identify distinct subtypes of obsessive-compulsive symptoms (OCS) among college students using latent profile analysis (LPA), and to examine the independent associations of demographic characteristics and dimensions of the Big Five Personality Inventory with these OCS subtypes.
methodsA cross-sectional study was conducted among 1,107 college students at a university in Zhengzhou City. The survey utilized the Questionnaire Star platform, employing the Big Five Inventory-10 (BFI-10) and the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). LPA was employed to identify potential subtypes of OCS among university students. Multinomial logistic regression analysis was then used to examine the independent associations of demographic characteristics and personality dimensions with the different OCS subtypes.
resultsLPA revealed three distinct subtypes of OCS among the university students: the mild OCS subtype accounted for 50.8%, the moderate OCS subtype accounted for 36.7%, and the severe OCS subtype accounted for 12.5%. Significant differences were observed across the different OCS subtypes concerning gender and Internet use duration (P < 0.05). Multiple logistic regression analyses further revealed that gender, daily internet usage duration, extraversion, agreeableness, and neuroticism were significant predictors of the latent profile of OCS (P < 0.05). Specifically, males, longer daily internet usage, milder levels of extraversion and agreeableness, and severe levels of neuroticism were associated with more severe OCS subtypes.
conclusionThis study identified distinct OCS subtypes among college students and several key demographic and personality predictors. These findings provide a theoretical basis for the early identification and personalized intervention for OCS in this population.
