Personality correlates of eating pathology severity and subtypes in The National Comorbidity Survey Adolescent Supplement.

OBJECTIVE

We examined how personality traits are associated with eating pathology (EP) across a range of severities and symptom subtypes.

METHOD: The National Comorbidity Survey Adolescent Supplement (N = 10,148) was used to compare personality across severities (i.e., clinical Eating Disorders [EDs], subclinical disordered eating, preclinical weight concerns, or no weight/EP [no W/EP]), subclinical subtypes (i.e., Binge Eating Only, Binge-Purge, Binge-Restrict, Restrict-Purge, or no W/EP), and clinical subtypes (i.e., Anorexia Nervosa [AN]), Bulimia Nervosa [BN], Binge Eating Disorder [BED], internalizing disorders, or no ED or internalizing disorder) of EP.

RESULTS

More severe EP was associated with more extreme personality trait endorsements. Impulsivity-related traits did not consistently distinguish binge eating/purging from restricting subtypes, although behavioral disinhibition differentiated adolescents with BN or BED from AN.

CONCLUSION

Personality traits related to affectivity and impulsivity were more consistently associated with severity rather than subtype of EP.
