Relationship between eating styles and temperament in an Anorexia Nervosa, Healthy Control, and Morbid Obesity female sample.
OBJECTIVE
Eating styles have been studied in both Obesity (OB) and Eating Disorders (ED), but they have not been examined in these two weight conditions together. The present study explores differences in eating styles in an Anorexia Nervosa (AN) and OB sample, compared to Healthy Controls (HC), and it analyses their relationship with Body Mass Index (BMI) and personality traits.


METHODS
The total sample consisted of 291 female participants (66 AN, 79 OB and 146 HC).


RESULTS
Assessment measures included the Dutch Eating Behaviour Questionnaire-DEBQ- and the Temperament and Character Inventory-Revised-TCI-R-.


RESULTS
The MANCOVA test showed significant differences among the three groups for all eating styles, with emotional eating being more typical in the OB group and restrained eating more typical in the AN group. Partial correlation analyses showed relationships between emotional and external eating and BMI, as well as relationships with different temperament and character traits. The stepwise discriminant function analysis showed that the DEBQ correctly classified 65.6% of the sample into the three weight categories; when combined with the TCI-R, correct classification increased to 72.6%.


CONCLUSIONS
Weight conditions showed different eating behaviour patterns. Temperament and character traits were related to eating behaviours. DEBQ and TCI-R were able to discriminate between groups. Differences in eating styles in the weight groups can have implications for understanding the development and maintenance of OB and ED.
