Using a measure of the DSM-5 alternative model of personality disorder traits to define personality types in people seeking eating disorder treatment: a pilot study.
Article in Journal of eating disorders, 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
backgroundThere has been increasing research focus on the relationship between eating disorders and personality types and traits separately. In this pilot study, we present a mixed methods approach to classify individuals with an eating disorder as Overcontrol (OC; anxiousand perfectionistic), Undercontrol (UC; emotionally dysregulated) or resilient (without personality pathology). We then explore the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, Alternative Model of Personality Disorder trait profiles associated with OC and UC presentations.
methodsTwenty individuals (12 women, 2 men, 6 gender-diverse) seeking treatment for eating disorders were classified as OC, UC or resilient based on a structured clinical interview and clinician rating scales supplemented by self-report measures of depression, anxiety and stress. Group differences in DSM-5 alternative model personality traits and eating pathology were examined.
resultsTwelve individuals were classified as OC, six as resilient, and two as UC. The OC group scored higher than the resilient group on the following DSM-5 alternative model of personality disorder traits: Anhedonia, Depressivity, Emotional Lability, Submissiveness and Separation Insecurity with large effect sizes (Cohen's d = .0.80-1.84).
conclusionsOur research suggests the importance of assessing the public and private nature of problem behaviour within clinical assessment. In addition, our results indicated potential benefit of further research focused on understanding personality types in the context of DSM-5 pathological personality traits.
