| dc.description.abstract | The purpose of this thesis was three-fold: (a) examining the relation between psychosocial and psychopathological factors in body dissatisfaction, restricting eating, excessive exercise, purging, and binge eating; (b) investigating if there are distinct groups of disordered eating patterns that underlie underweight, normal weight, overweight, and obesity; and (c) assessing the role of psychological flexibility in eating pathology. Negative emotionality, impulsivity, perfectionism, stress, pressure from peers and media, and depressive symptoms predicted body dissatisfaction. Extraversion, conscientiousness, impulsivity, perfectionism, peer pressure, and symptoms of borderline personality disorder, obsessive-compulsive personality disorder, depression, and anxiety predicted restricting eating. Extraversion, conscientiousness, impulsivity, perfectionism, stress, peer pressure, and depressive and anxiety symptoms predicted excessive exercise. Agreeableness, open-mindedness, impulsivity, stress, peer pressure, and obsessive compulsive personality disorder symptoms predicted purging. Negative emotionality, agreeableness, impulsivity, stress, pressure from family and media, and depressive symptoms predicted binge eating. Obese participants reported higher body dissatisfaction, binge eating, negative emotionality, open-mindedness, pressure from family, and depressive and anxiety symptoms. Underweight participants indicated higher restricting eating and lower pressure from the media. Since diminished psychological flexibility was associated with higher disordered eating, acceptance and commitment therapy may mitigate disordered eating, which in turn may improve unhealthy weight. | |
