Personality dimensions could explain resilience in patients with eating disorders

Resilience can be defined as the ability to maintain health in the face of adversity. Resilience has been associated with personality traits. Personality traits in the context of Eating Disorders (ED) have also been examined. However, the relationship between resilience and personality profile in patients with ED has not been studied. The aim of this study is to investigate whether personality dimensions impact on resilience, in patients with ED, compared to healthy participants.

Connor and Davidson resilience scale, as a measure of resilience and temperament-character inventory, as a measure of personality dimensions, were completed by 100 participants: 50 (50%) healthy University students (controls subgroup) and 50 (50%) patients with ED, matched on age and gender.

Patients with ED showed lower resilience than healthy participants and scored higher on harm avoidance, and lower on reward dependence, self-directedness and cooperativeness than controls. Lower harm avoidance, higher persistence and higher self-directedness were associated with resilience in both subgroups. Self-directedness and persistence predicted resilience in both subgroups. Only Harm Avoidance predicted resilience in patients' subgroup.

To our knowledge, there are no existing data examining the effect of personality dimensions in resilience, in the context of ED. We found that only the effect of Harm Avoidance in resilience was different among the participants' subgroups. In conclusion, Harm Avoidance could explain differences in resilience between healthy participants and patients with ED.
