One of the trends I'm seeing in eating disorder care is breaking free from the 50 minute once a week appointments.
Programs like the UCSD 5-Day Intensive multi-family program for the whole family is one model. A growing number of all-day/inpatient programs like Kartini Clinic and Denver Children's Hospital offer parents a chance to stay at local Ronald McDonald Houses while participating on a daily basis. I see more Partial Hospitalization and Day Programs adding more family involvement as well.
Another new idea: Beumont Hospital's Weekend Camp program.
"Supported by a grant from the Flinn Foundation, our weekend camp, for children 13 to 18 years old who have been diagnosed with an eating disorder and at least one parent or guardian, will take place from 10 a.m. Friday, April 13 through 4 p.m. Sunday, April 15 at the Skyline Camp and Retreat Center in Almont, MI."
