Personality and eating disorders: a decade in review.
Personality traits have been implicated in the onset, symptomatic expression, and maintenance of eating disorders (EDs). The present article reviews literature examining the link between personality and EDs published within the past decade, and presents a meta-analysis evaluating the prevalence of personality disorders (PDs) in anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) as assessed by self-report instruments versus diagnostic interviews. AN and BN are both consistently characterized by perfectionism, obsessive-compulsiveness, neuroticism, negative emotionality, harm avoidance, low self-directedness, low cooperativeness, and traits associated with avoidant PD. Consistent differences that emerge between ED groups are high constraint and persistence and low novelty seeking in AN and high impulsivity, sensation seeking, novelty seeking, and traits associated with borderline PD in BN. The meta-analysis, which found PD rates of 0 to 58% among individuals with AN and BN, documented that self-report instruments greatly overestimate the prevalence of every PD.
