Examining Clinical Symptoms and Personological Traits in Adolescents With Anorexia Nervosa: A Network Analysis Approach.
Article in Journal of clinical psychology, 2025. 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
objectiveDespite advancements in treatment, research indicates that fewer than half of patients with anorexia nervosa (AN) achieve full recovery by the end of their treatment. Network analysis provides a novel framework for understanding the central features of this complex psychopathology, potentially identifying critical elements that could enhance intervention strategies. While evidence suggests that personality traits play a significant role in the etiology, symptomatic expression, and maintenance of AN, no studies have yet utilized network analysis to explore the relationships among personality traits, eating disorder (ED) symptoms, and common psychiatric comorbidities in adolescents with AN. This study aims to fill this gap by applying network analysis to examine the interplay between ED symptoms, anxiety and depressive symptoms, and personality traits in a sample of 243 adolescents with AN (92.6% female), aged 12 to 17 years (M age = 14.7 ± 1.4), recruited from five University Health Centers across Quebec, Canada.
methodsUpon admission, participants completed the Eating Disorder Inventory-3 (EDI-3), the Multidimensional Anxiety Scale for Children (MASC), the Children's Depression Inventory 2 (CDI 2), and the Millon Adolescent Clinical Inventory (MACI). All variables were incorporated into a network analysis.
resultsThe analysis revealed that submissive, conforming, self-demeaning, and inhibited personality traits were central nodes. Among ED symptoms, drive for thinness was the most prominent, with depressive symptoms exhibiting the highest centrality among comorbid conditions.
conclusionThese results highlight the complex interplay between ED symptoms, psychiatric comorbidities, and personality traits in adolescents with AN. These findings suggest that interventions may benefit from focusing on emotional regulation and interpersonal dynamics, with particular attention to assertiveness training and strategies to help adolescents express and address their needs in relationships.
