October 6, 2010 ( Upgraded October 7, 2010 )– Family-based treatment (FBT) is more reliable than standard adolescent-focused specific therapy (AFT) in treating youths with anorexia nervosa, according to a new randomized clinical trial conducted collectively by scientists from the Stanford University School of Medicine in California and from the University of Chicago Medical Center in Illinois.
Although both treatments “caused considerable enhancement and were likewise efficient” in producing a full remission of the illness at the end of treatment (EOT), FBT doubled the efficiency of AFT at both the 6-month and 12-month follow-ups, report the private investigators.
“This study strongly recommends that as a first-line treatment, in basic, family-based interventions are superior,” co-lead study author James Lock, MD, PhD, professor of psychiatry and pediatrics at Stanford and psychiatric director of the Comprehensive Eating Disorders Program at Lucile Packard Kid’s Hospital at Stanford, told Medscape Medical News.
“We found that usually, [FBT] had to do with two times as reliable at promoting full weight restoration and healing of eating disorder symptoms compared with private therapy. Both treatments were helpful in enhancing signs to a specific degree, but household treatment was two times as reliable in getting someone well,” added Dr. Lock.
He kept in mind that the number 1 takeaway for clinicians is recognizing that households can be helpful in getting kids to conquer their eating disorders. “Including them in treatment, including them in helping change the environments in which their kids are living and working and going to school is a reliable strategy for assisting the kids get over anorexia.
“On the other hand, an overfocus on teen autonomy and developmental problems might really interfere in some methods, a minimum of initially, in overcoming this condition,” stated Dr. Lock.
The research study was released in the October problem of the Archives of General Psychiatry.
Research “Frantically Required”
“Although various kinds of individual and household therapy are used in the treatment of teenagers with [anorexia], most have actually not been methodically taken a look at,” compose the research study authors. “Thus, there is little assistance for providing evidence-based interventions.”
They keep in mind that, to date, just 6 randomized medical trials have been published on adolescents with anorexia nervosa.
“This research was frantically required,” said Dr. Lock. “There are just 6 randomized controlled treatment studies worldwide literature, yet this disease was described over 120 years earlier. It’s a remarkably percentage of data offered the seriousness of the condition and its effect on physical and mental health.”
The scientists define AFT as “a psychodynamically informed private psychotherapy concentrating on boosting autonomy, self-efficacy, individuation, and assertiveness while also including collateral parent conferences to support individual treatment.”
On the other hand, FBT “promotes adult control of weight restoration while improving familial operating as it connects to adolescent development.”
For this research study, 121 patients between the ages of 12 and 18 years (imply age, 14.4 years) and diagnosed as having anorexia (mean period of illness, 11.3 months) were enrolled between October 2004 and March 2007. They were then randomized to receive 24 hr of either outpatient FBT (n = 61, 89% woman) or ABT (n = 60, 93% female) for 1 year.
Assessments were conducted for all participants at EOT and at 6- and 12-month posttreatment follow-ups.
The primary outcome measure was complete illness remission. Partial remission rates, modifications in body mass index (BMI), and changes in Eating Disorder Evaluation (EDE) scores were all secondary steps.
Complete remission was specified as 95% of the normal weight anticipated for the client’s sex, age, and height and a typical global EDE rating within 1 SD of released methods.
Partial remission was defined as reaching 85% of the patient’s anticipated weight for height.
In addition, the Set up for Affective Disorders and Schizophrenia for School-Aged Children interview was utilized to assess for comorbid psychiatric conditions
FBT Substantially More Efficient
Results at the end of the research study revealed that 26% of all clients reported a comorbid psychiatric condition.
Although no statistically significant distinctions were found for complete remission at EOT in between the 2 groups (P =.055), FBT was substantially exceptional at the 6-month (40% vs 18% for FBT and AFT; P =.03) and 12-month (49% vs 23%; P =.02) follow-up time points.
For partial remission, FBT was substantially exceptional to AFT at EOT (89% vs 67%; P =.02) however not during the follow-ups.
FBT individuals likewise had considerably higher BMI percentiles (suggest distinction, 8.0; 95% confidence interval, 0.1– 15.9; P =.048) and higher modifications in EDE scores (P =.03) at EOT.
“These outcomes were a bit unexpected as I had actually hoped AFT would be a little more powerful for remission,” said Dr. Lock. “Also surprising was that [FBT] was more efficient in changing eating-related psychopathology throughout treatment.”
The clients in the FBT group were also hospitalized substantially less often during the treatment stage than were those in the AFT group (15% vs 37%; P =.02).
“When we put people in hospitals, not only do we disempower moms and dads, we’re likewise taking the kid out of their life, which is rather distressing for a 13- or 14-year old. This treatment suggests that you don’t truly need to do that,” explained Dr. Lock.
“I believe that learning to manage these habits in the home, school, or work environments is a way of guaranteeing that the habits are going to be generalizable gradually in their lives,” he included.
He kept in mind that overall, both AFT and FBT “are rational techniques” to dealing with anorexia in adolescents. Nevertheless, AFT “is just not as efficient and as effective as family treatment, at least in this study.”
Dr. Lock explained that AFT may be required, though, “in scenarios where family treatment can’t be done. It’s also more readily available in lots of communities and there are great therapists who can truly assist these kids. However if it was my kid, I would pick to start with family-based treatment.”
The researchers conclude that more studies are required “comparing FBT with other reliable treatments, consisting of cognitive behavioral treatment and other kinds of household treatment, to mark the very best method to dealing with teen anorexia.”
Crucial First Step
“I think this is a crucial, well-done study and an important intervention. There’s a fair amount of excitement about it,” David B. Herzog, MD, Harvard Medical School Endowed Professor of psychiatry in the field of consuming disorders, and director of the Harris Center for Education and Advocacy in Eating Disorders at Massachusetts General Healthcare Facility in Boston, told Medscape Medical News. He was not involved in this research study.
Although there have been several research studies revealing that family-based treatment is an appealing intervention, Dr. Herzog stated, it is very important to keep in mind that this research study involved young clients who were ill for less than a year.
“So it talks to early intervention,” he described. “If you have someone you can recognize early on with this problem and you provide a good intervention such as family-based treatment or, if that’s not readily available, an individual therapy that’s adolescent focused, I think this reveals that these individuals will have a reasonable result.”
He noted that the huge concerns are: “For whom, what, and when? That always needs to be addressed. You need a household that wants to participate at this level of treatment, making themselves offered.”
He also wondered what would occur to clients who are 17 to 18 years of ages who have had the illness for several years, and he questioned why comorbidities weren’t took a look at more detailed.
“These people are frequently in a variety of treatments since they do not only have the 1 problem of anorexia. Not uncommonly, they also have depression or a stress and anxiety condition, and in some cases medications are utilized. What role does each of those have? I think that’s something that might have potentially been dealt with a bit more,” stated Dr. Herzog.
He also questioned completion points used. “They took a look at 6 months and 12 months after treatment and, once again, that’s only part of the story. A great deal of people that receive family-based therapy need additional treatment. But what kind, and for how long? If you were to follow these young folks 3 or 4 years out, how would they be doing?”
“That said, I do like the concept of family-based treatment as a preliminary intervention, a minimum of for a group that is young and has not been ill for too long a period of time, and when it’s offered and appropriate for those households who can take part,” concluded Dr. Herzog. “Overall, I think this research study is an important initial step.”
The study was funded by grants from the National Institutes of Health. Dr. Lock and 2 other study authors report getting royalties from Guilford Press for books on family-based treatment. Dr. Herzog has actually divulged no pertinent financial relationships.

A new randomized trial finds that family-based treatment is two times as reliable as private therapy in producing complete remission at 6 and 12 months after treatment in teenagers with anorexia nervosa.
