One reason that the prevalence of bulimia nervosa has increased since the publication of theDSM-5-TR is that
a) talk shows have made it easier for people with the disorder to make themselves known.
b) binging has replaced restricting food intake as the preferred way of manifesting the disorder.
c) research has shown that the presentation of thin women in the media has exerted increased influence on girls and women in recent years.
d) the criteria for determining the diagnosis of bulimia nervosa were more strict in the DSM-IV than they are in the DSM-5.
