The behavioral component of cognitive-behavioral therapy in treating bulimia nervosa involves:

A) identifying and analyzing the client's childhood experiences with food.
B) introducing forbidden foods back into the client's diet.
C) providing negative reinforcements every time the client purges.
D) prescribing selective serotonin reuptake inhibitors (SSRIs) to the client.

The behavioral component of cognitive-behavioral therapy for bulimia nervosa typically involves gradually introducing previously "forbidden" foods back into the client's diet to help reduce bingeing and purging behaviors. This can help the client learn to normalize their eating patterns and reduce their reliance on restrictive eating. Techniques for addressing negative thought patterns and challenging distorted beliefs about food and body image are typically included in the cognitive component of treatment. Providing negative reinforcements for purging behaviors would likely be counterproductive and undermine the therapeutic alliance. While medication may be useful for some individuals with bulimia nervosa, it is not typically considered a first-line treatment and would not be considered a part of the behavioral component of cognitive-behavioral therapy.
