For all eating disorders,_____ is crucial.

A) family structure
B) family function
C) discipline
D) school-based intervention

Family function is crucial in the treatment and recovery of individuals with eating disorders. Family therapy is often used to address dysfunctional family dynamics that may contribute to the development and maintenance of the eating disorder. A positive and supportive family environment can also facilitate the individual's progress towards recovery. The other options (family structure, discipline, and school-based intervention) may have some relevance in certain cases, but they are not as universally crucial as family function.
