The relationship between perfectionism, neuroticism, and exercise addiction risk: a latent profile analysis and the mediating role of social physique anxiety.

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
Background: Exercise addiction (EA) is an emerging public health concern among university students, yet limited attention has been paid to heterogeneity in personality-related risk profiles. This study aimed to identify latent profiles based on perfectionism and neuroticism and to examine whether social physique anxiety (SPA) statistically mediates the association between these profiles and EA. Methods: Between April and May 2025, this study surveyed 481 university students using the Frost Multidimensional Perfectionism Scale (FMPS), the NEO Five-Factor Inventory-Neuroticism Subscale (NEO-FFI-N), the Social Physique Anxiety Scale (SPAS), and the Exercise Addiction Inventory (EAI). Data from 481 participants were processed using SPSS 26.0. Latent profile analysis was conducted using Mplus 8.0, and mediation analysis was performed using the PROCESS 4.1 macro. Results: Latent profile analysis identified three perfectionism-neuroticism profiles: low (32.64%), moderate (57.38%), and high (9.98%). Compared with the low perfectionism-neuroticism profile, both the moderate and high profiles were associated with higher EAI scores. The mediation analysis was consistent with a partial statistical mediating role of SPA in these associations. For the moderate profile, the total effect on EAI scores was 0.78 (SE = 0.10, 95% CI [0.59, 0.97]), the direct effect was 0.54 (SE = 0.10, 95% CI [0.35, 0.73]), and the indirect effect through SPA was 0.24 (SE = 0.04, 95% CI [0.16, 0.34]). For the high profile, the total effect on EAI scores was 1.60 (SE = 0.16, 95% CI [1.28, 1.92]), the direct effect was 1.18 (SE = 0.16, 95% CI [0.86, 1.50]), and the indirect effect through SPA was 0.43 (SE = 0.08, 95% CI [0.28, 0.60]). Conclusion: University students with high-risk personality traits showed higher EAI scores, partly through elevated SPA. This psycho-behavioral association highlights the need to move beyond a purely behavior-focused perspective and adopt a more integrated approach that considers both personality traits and social evaluative sensitivity. Enhancing identification and intervention mechanisms for at-risk individuals may help promote more stable and sustainable patterns of physical activity among university populations.
