Research has shown that the most effective type of treatment for bulimia nervosa is

A) SSRIs.
B) interpersonal therapy.
C) group therapy.
D) cognitive-behavioural therapy.
E) supportive psychotherapy.

Cognitive-behavioural therapy (CBT) has been found to be the most effective type of treatment for bulimia nervosa. CBT focuses on changing negative thought patterns and behaviours associated with disordered eating, and it can help individuals develop healthy coping skills and reduce unhealthy eating behaviours. While antidepressant medications like SSRIs may be used in conjunction with therapy, they are not typically considered the most effective treatment on their own. Interpersonal therapy, group therapy, and supportive psychotherapy may also be beneficial for some individuals with bulimia nervosa, but research has consistently shown that CBT produces the best outcomes.
