Moderating Effect of Metacognition on the Relationship between Perfectionism, Body Image Disturbance, and Body Mass Index in Anorexia Nervosa: A Cross-Sectional Study.

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
backgroundDespite theoretical concepts about the key role of perfectionism in the formation of the symptoms of anorexia nervosa (AN), the aspects of the mutual influence between body mass index (BMI), perfectionism, and body image in patients with AN remain insufficiently studied or contradictory. Studying integrative cognitive processes, such as metacognition, may reveal new mechanisms of perfectionism's influence on the clinical manifestations of AN.
aimThe assessment of the moderating effect of metacognition on perfectionism associated with BMI and body image in patients with AN.
methodsA cross-sectional study was conducted involving patients with AN who were undergoing inpatient treatment. Perception of one's own body was assessed using the Body Image Questionnaire. Perfectionism was assessed using the Multidimensional Perfectionism Scale. The level of metacognition of patients was assessed using the Metacognition Assessment Scale-Abbreviated, which evaluates Self-reflectivity, Understanding the other's mind, Decentration, and Mastery (the ability to develop adaptive strategies for coping and behaviour regulation). BMI was also recorded.
resultsA total of 130 patients were examined. At a Mastery score of ≥4 higher perfectionism scores were associated with an increase in BMI, and at a Mastery level of ≤1 a higher level of perfectionism was associated with decreasing of BMI. Even with minimal Self-reflectivity scores (≥2), the negative effect of perfectionism on body image was evident. Body image disturbance was positively correlated with perfectionism. No correlations were found between BMI and perfectionism and between BMI and body image disturbance.
conclusionThe effect of perfectionism on body image disturbance and BMI in patients with AN depends on the magnitude of Self-reflectivity and Mastery. The obtained data indicate the necessity of incorporating psychotherapy aimed at the development of metacognition in patients with AN.
