Orthorexia in obsessive-compulsive personality disorder: the impact of perfectionism and metacognition.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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 personality disorder (OCPD) is characterized by a rigid need for control, orderliness, and perfectionism, often impairing functionality. Traits such as striving for an "ideal" figure can lead to orthorexic tendencies, characterized by an obsessive focus on healthy eating, which can result in significant social, psychological, and physical complications. This study investigates the presence of orthorexic tendencies in individuals with OCPD and examines whether these tendencies are predicted by metacognition and perfectionism, with a focus on the mediating role of metacognition.
methodsThe study included 73 patients diagnosed with OCPD through the DSM-5 Structured Clinical Interview (SCID-5-PD) and 73 healthy controls matched by age, sex, and education level. Perfectionism, orthorexia, and metacognition were assessed via the Frost Multidimensional Perfectionism Scale (FMPS), Meta-Cognition Questionnaire-30 (MCQ-30), and ORTO-11 scale. Pearson correlation, linear regression, and mediation analyses were conducted to explore these relationships.
resultsOCPD patients had lower BMIs and higher scores for perfectionism, orthorexia, and metacognitive activity than did the control group. A negative correlation was found between the FMPS and ORTO-11 scores. MCQ scores were positively correlated with FMPS scores and negatively correlated with ORTO-11 scores. In the mediation analysis, metacognition was found to have a partial mediating effect on the relationship between perfectionism and orthorexia.
conclusionPerfectionism and dysfunctional metacognition significantly contribute to orthorexic tendencies in individuals with OCPD. These findings suggest that metacognitive therapy may effectively address and reduce orthorexic behaviors in this population.
