What is a primary focus when treating a client with anorexia nervosa?

Focusing on addressing psychological distortions is crucial when treating a client with anorexia nervosa, as this eating disorder is deeply rooted in distorted body image and unhealthy thought patterns surrounding food, weight, and self-worth. Clients often perceive themselves as overweight despite being underweight, which influences their food intake and overall behavior.

Therapeutic approaches aim to challenge and modify these distorted beliefs and attitudes. By addressing these psychological components, clinicians help clients develop a more realistic and healthier body image, ultimately working towards healthier eating patterns and behaviors. This psychological intervention is foundational in treatment, as it can lead to significant improvements in the client's relationship with food and themselves.

The other options, while relevant in broader treatment contexts, do not have the same primary focus. For instance, emphasizing family dynamics can be helpful, but the immediate concern must deal with the individual’s psychological state. Reinforcing caloric restriction and increasing physical activity contradict the goal of recovery, which focuses on restoring normal eating and addressing the underlying issues contributing to the disorder.
