Dimensional personality pathology and disordered eating in young adults: measuring the DSM-5 alternative model using the PID-5

Abstract

IntroductionThe Personality Inventory for DSM-5 (PID-5) is a self-report measure of personality pathology designed to measure pathological personality traits outlined in the DSM-5 alternative model of personality disorders. Within the extensive literature exploring the relationship between personality and disordered eating, there are few that explore the relationship between the PID-5 and disordered eating behaviours in a non-clinical sample of males and females: restrictive eating, binge eating, purging, chewing and spitting, excessive exercising and muscle building.MethodsAn online survey assessed disordered eating, PID-5 traits and general psychopathology and was completed by 394 female and 167 male participants aged 16–30. Simultaneous equations path models were systematically generated for each disordered eating behaviour to identify how the PID-5 scales, body dissatisfaction and age predicted behaviour.ResultsThe results indicated that each of the six disordered behaviours were associated with a unique pattern of maladaptive personality traits. The statistical models differed between males and females indicating possible differences in how dimensional personality pathology and disordered eating relate.DiscussionIt was concluded that understanding disordered eating behaviour in the context of personality pathology may assist formulating potentially risky behaviour.

Identifying overcontrol and undercontrol personality types among young people using the five factor model, and the relationship with disordered eating behaviour, anxiety and depression

“…Although UC personality type has previously been linked to increased binge eating and purging behaviour [ 9 , 30 ], the relationship between personality type and other eating behaviours has not been explored previously. For example, past research has identified a relationship between compulsive exercise and elevated Neuroticism [ 80 , 81 ] and Extraversion [ 81 ], and chewing and spitting behaviour has previously been related to impulsivity [ 50 , 69 ]. What can be implied is that elevated extraversion and impulsivity might put UC individuals at higher risk of compulsive exercise and chewing and spitting, respectively.…”

“…Data from this study have previously been described elsewhere [ 50 , 69 ]. In order to attract prospective participants, advertisements providing a brief overview of the goals of the study and anticipated time commitment were posted on social media.…”

Replicability of the five‐factor structure of DSM‐5 and ICD‐11 trait systems and their associations with binge eating and bipolar spectrum psychopathology

“…Specifically, we compared the structures of the DSM-5 and ICD-11 systems to predict scores on the dimensional measures of both mental disorders. A few studies address the overlap between maladaptive traits and BED or BSD (Gilmartin et al, 2023;. Some reports have also shown that some domains of the DSM-5 (Negative Affectivity, Disinhibition, and Psychoticism) and the ICD-11 (Negative Affectivity and Disinhibition) systems are significantly related to the symptoms of BED and BSD Sellbom et al, 2022;Stricker et al, 2022).…”
