Abstract
OBJECTIVE: Anorexia nervosa (AN) has been associated with impulse regulation problems. This study investigated subjective and behavioural impulsivity in women with anorexia nervosa (n=15) and a control group (n=16). METHOD: A self-report measure (the impulsiveness, venturesomeness, and empathy questionnaire; I(7)) and two behavioural measures (a continuous performance task [CPT]; and a novel risk taking measure [Bets 16]) of impulsivity were used along with the Beck Depression Inventory (BDI). RESULTS: The AN group had elevated BDI scores and lower self-reported impulsiveness and venturesomeness scores, but they also displayed impulsive behaviour on the CPT (more errors of commission with faster reaction times). DISCUSSION: The coexistence, in AN, of self-reported self-control and behavioural impulsivity indicates that the relationship between impulsivity and disordered eating in AN is more complex than previously recognised and supports the view that self-awareness in AN is low.
