Using the alternative model of personality disorders for DSM-5 traits to identify personality types, and the relationship with disordered eating, depression, anxiety and stress.

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 is a substantial and growing evidence base that has identified three distinct personality types (Overcontrol, Undercontrol and Resilient) among samples of individuals with eating disorders, as well as non-clinical samples. Even in studies where up to six personality types have been identified, the three core types representing Overcontrol, Undercontrol and Resilient consistently emerge. The aim of the research was to explore whether latent Overcontrol and Undercontrol personality types could be identified using pathological personality types as part of the Alternative Model for Personality Disorders published in DSM-5. We further aimed to understand how these personality types were associated with eating pathology, depressed mood and anxiety.
methodsA total of 391 women, 167 men and 10 gender-diverse individuals aged 16 to 31 years completed measures of the alternative model of personality disorder traits, disordered eating behaviours, eating pathology, depression, anxiety and stress. A systematic four-step process using hierarchical, k-means, and random forest cluster analyses were used to identify the best fitting cluster solution in the data.
resultsThe results revealed a four-cluster solution that represented overcontrol, undercontrol, resilient and an antisocial/psychoticism cluster. The overcontrol, undercontrol, and antisocial/psychoticism types were all associated with increased disordered eating, eating pathology, depression, anxiety and stress compared to the resilient types, with the undercontrol cluster scoring significantly higher than the other three clusters on all measures of clinical pathology.
conclusionsPathological personality traits, as conceptualised within the DSM-5 alternative model of personality disorders may have merit for identifying overcontrol and undercontrol personality types. Our findings provide additional evidence that both overcontrol and undercontrol personality types are associated with increased eating pathology, depression, anxiety and stress.
