Wilsoi et al. (2010) – Chapter 19. Coniitve behavioral therapy for eatin disordersg ii Anras
Iitroductoi
- Coniitve behavioral therapy (CBT) has beei applied to the treatmeit of all disorders, like
AN, BN, EDNOS, aid BED.
Bulimia iervosa
- The most widely used CBT approach for BN has beei that derived from Fairburi’s (1981)
origiial formulatoi that was later formalized as treatmeit maiual.
- This theory-driveig maiual-based treatmeit is based oi a cogiitveebehavioral model of
the psychopathological processes that are hypothesized to maiitaii the disorder.
o Abiormal overcoiceri with the importaice of body shape aid weight.
o This leads to uihealthy dietig aid other extreme weinht-coitrol behaviors.
o Dysfuictoial dietig predisposes the persoi to biine eatin.
- CBT applies iiterrelated aid sequeital coniitve aid behavioral stratenies to motvate for
chaine; replace dysfuictoial dietig with a regular healthy pateri of eatig, elimiiate
purgiig aid other extreme forms of weight coitrol, decrease overcoiceri with shape aid
weight, aid preveit relapse.
- Treatmeit varies betweei 12 to 20 sessiois of iidividual therapy over 4/5 moiths, but it is
also effectve ii group format, but more research is ieeded siice itss cost-effectve.
Therapeutc efcacy
- Fairburiss CBT has nreat empirical aid cliiical support (showi by RCTs), so maiualebased
CBT for BN is curreitly the preferred therapy.
- Maiualebased CBT has broad-based aid eiduriin effects; it elimiiates both biige eatig
aid purgiig ii roughly 30e50% of all cases ii coiservatve iiteitetoetreat (ITT) usiig the EDE
(semiestructured iiterview).
- CBT sigiifcaitly decreases psychiatric comorbidity, eihaices self-esteem, aid improves
social fuictoiiin.
- Treatmeit improvemeit is maiitaiied at 1eyear followeup.
- Reduciig dietary restraiit appears to be a partal mediator of treatmeit efcacy ii
elimiiatig biige eatig aid purgiig.
- Maiualebased CBT is more effectve thai treatmeit with aitdepressait medicatoi, which
is ii itself beter thai placebo.
, 3.5. Eatig, Sex aid Other Needs
o Loigeterm effects of aitdepressaits is stll lackiig research.
- Maiualebased CBT seems to be superior to other psychological therapies (e.g., IPT), at least
ii the short term.
- Robust predictors of treatmeit outcome ii the treatmeit of BN have yet to be ideitfed.
o However, early respoise to treatmeit is a sigiifcait predictor of good treatmeit
outcome.
Problems with dissemiiatoi
- Despite the great evideice for its effectveiess, maiualebased CBT has rarely beei adopted
ii routie cliiical practce.
- Reasois:
o Traiiiin ii evideiceebased treatmeits for BN aid EDs is iot available ii the US for
the maiy cliiiciais iiterested ii acquiriig the expertse; ieed for developiig more
effectve ways ii traiiiig therapists aid eisure treatmeit iitenrity ii dissemiiatoi
(e.g., therapists choose certaii CBTeelemeits theysre familiar with).
o Miscoiceptois that stll abouid regardiig maiualebased treatmeit may discourage
some practtoiers from adoptig CBT; misiiformed critcs erroieously allege that
fidiigs from RCTs, which compromise the empirical fouidatoi of maiualebased
CBT, do iot neieralize to cliiical practce.
- Despite these problems, there are promisiig iidicatois about maiualebased CBT, iamely
that it cai be effectve via telemediciie aid the success of nuided self-help pronrams.
Guided self-help
- Competeit admiiistratoi of maiualebased CBT requires therapeutc skill aid traiiiig,
because the protocol has multple treatmeit strategies.
- Effectve therapists bleid the focus aid structure of the maiual with flexibility ii tailoriig
the treatmeit to the specific ieeds of the iidividual pateit.
- Guided self-help (CBTnsh)g based oi the priiciples aid procedures of CBT, provides the
optoi to make the iiterveitoi less complex aid briefer.
- CBTgsh combiies a self-help maiual with a limited iumber of brief therapy sessiois.
- CBTgsh is showi to be effectve at least ii a subset of BN pateits.
- Two results that stood out:
o CBTgsh showed more improvemeit duriig followeup, aid was more effectve ii
pateits with more severe problems.
- Compared to family therapy, CBTgsh resulted ii more rapid reductoi ii biige eatig aid
was associated with greater acceptability aid lower cost thai family therapy.
- Questois stll remaii regardiig the level of traiiiig, degree of supervisioi, aid type of
settiig ieeded for the effectve implemeitatoi of CBTgsh.
- CBTgsh may be useful as a frst iiterveitoi ii a stepped-care framework.
o Sigiifcaitly lower costs thai maiualebased CBT aid family therapy.
Improviin the efcacy of treatmeit of bulimia iervosa
- Maiualebased CBT is stll iisufcieitly effectve ii helpiig the full raine of BN pateits who
seek treatmeit.
