FBT is the most effective treatment for adolescent anorexia nervosa based on evidence from multiple randomized controlled trials:
1) FBT leads to faster weight gain and symptom improvement compared to alternative therapies like adolescent focused therapy.
2) FBT reduces the need for hospitalization more than alternatives.
3) For bulimia nervosa, FBT and family therapy may lead to better outcomes than individual therapies like CBT at post-treatment and follow-up, though alternatives can also be effective.

o First-line in-patient psychiatric treatment
does not provide advantages over out-
patient management.
o Out-patient treatment failures do very
poorly on transfer to in-patient facilities.

15. Conclusions
o Outcomes were similar with either MS or WR
when inpatient treatment is combined with
outpatient FBT.
o Significant cost savings will result from
combining brief hospitalization with FBT.

18. Conclusions
o DP after short inpatient care in adolescent non-
chronic AN seems no less effective than IP for
weight restoration and maintenance during the
1st yr after admission and at 12-month F/U.
o DP might be a safe and less costly alternative
to IP.
19. Summary for Inpatient TX
o First-line in-patient psychiatric treatment does not
provide advantages over day-patient or out-
patient management.
o Weight restoration at home is successful once
medical stabilization has been achieved.
20. ② Psychosocial Treatments for AN
The predominant models for treating adolescent AN are:
o Inpatient weight restoration
o Outpatient psychosocial treatment
o Family-Based Treatment (FBT) is family focused and aims
at symptom management by parents early in treatment.
o Adolescent Focused Therapy (AFT) is an individual
therapy and aims to promote self-efficacy, self-esteem,
and self-management of eating problems.
o Systemic Family Therapy (SyFT) places the focus on the
family system to draw on their existing strengths.
21. Summary of the 10 published RCTs for AN*
o 8 involved family-focused approaches (FBT, BFST or
SyFT).
o 3 involved individual therapy (CBT, supportive, or
adolescent focused therapy).
o 3 involved inpatient treatment.
o 0 involved any medication.

Remission is 95% mBMI for height and age according
to CDC norms + EDE within 1SD of community norms
o Approximates weight needed for return to full
physical health in young adolescents and addresses
growth, bone health, and hormonal function
o EDE threshold is in the normal range for community
sample and addresses minimization common in
adolescent AN

Remission at 6- and 12-month follow-up.
o FBT brings about faster weight gain early in
treatment with fewer hospital days.
o Remission rates stable at 4-yr follow-up, but
AFT ‘catches up’ with FBT.

47. ④ Reducing Need for Hospitalization
o Westmead Children’s Hospital, Sydney (2004) - reporting a
50% decrease in readmissions over the implementation
period (Wallis et al., Int J Adolesc Med Health, 2007).
o RCH in Melbourne (2009) - reporting 56% decrease in
admissions, 75% decrease in readmissions, 51% decrease in
overall hospital days (Hughes, Le Grange, Court et al., J Ped Child
Care, 2013).
48. Conclusions
o Early weight gain predicts outcome at end-
of-treatment.
o Adapting FBT for early non-responders
seems to improve outcomes for this subgroup.
o Subgroups for whom FBT is particularly
helpful have been identified.
o Family involvement underscored in good
outcomes, leading to reduced hospitalization.
49. Summary of Outpatient TX
o FBT should be the first-line outpatient treatment for
adolescents with AN when medically fit.
o FBT seems particularly effective at reducing the
need for hospitalization.
o Improved understanding of the workings of FBT.
o AFT and SyFT are feasible treatment alternatives.

o FBT-BN is superior to CBT-A at end-of-

o No statistically significant difference between
the two treatments at 12-month follow-up.
o FBT works faster at symptom remission and
benefits are maintained over time.
o Some progress in terms of treatment
moderators.
61. Summary for Adol BN
o FBT is a strong candidate as first-line outpatient
treatment for adolescents with BN.
o CBT seems a feasible alternative should the family
be unavailable.
o Little data on how these treatments work.
62. Overall Conclusions
o First-line inpt psychiatric treatment for AN does not
provide advantages over outpt management.
o FBT should be the first-line outpatient treatment for
adolescents with AN when medically stable.
o Utilizing families in the treatment of adolescents
with BN looks promising.
