Question | Answer |
---|---|
Eating Disorders and the DSM-IV Criteria | Anorexia: |
CBT Models of Eating Disorders-cognitive and behavioural components | Cycle that begins with a pursuit of thinness->leads to restrictive dieting->leads to feeling deprived & hungry->body eventually can no longer handle this deprivation so person engages in a binge->feels bad for binging so purges to compensate->guilt/shame |
Model of Anorexia | Issue with self-esteem->over-evaluation of weight, shape, eating->strict weight control behaviours->increased checking of weight, body, foods->decrease in rate of weight loss->perceived failure to control weight |
Model of Bulimia | Self-esteem issue>over-evaluation of weight, body, eating->dietary restraint->binge eating->purging behaviours |
Fairburn's Unified CBT Protocol | designed to work across many EDs. focus more on behaviours (restricting, binging/purging) & cognitions (over-valuation of shape & weight). Two versions: patients w/ BMI>17.5 (20 sessions in 20 weeks), patients w/ BMI<17.5 (40 sessions in 40 weeks). |
Stage 1 of Fairburn's Protocol | After medical assessment (EKG, electrolytes, bone density). Twice weekly (7 sessions, 4 weeks). Orient to model & get commitment. Info about weight & weight gain. Complete food logs. Learn to eat regular meals w/o eating in between. |
Food Schedule | Plan meals at given times, no more than 4 hours in between. Do not eat based on hunger cues. Do not skip meals. Do not eat in between planned meals. Eat whatever, but must eat at scheduled times only. |
Stage 2 of Fairburn's Protocol | Weekly sessions (2 sessions, 2 weeks). Assess progress. Identify barriers to change. Modify formulation of problem, as needed. |
Stage 3 of Fairburn's Protocol | Weekly (8 sessions, 7 weeks). Focus on problems that stared ED initially. Target: self-esteem, over-valuation of weight & shape, depression. Reduce checking/comparing. What it means to feel fat. Reduce rule-driven eating. |
Stage 4 of Fairburn's Protocol | Bi-weekly (3 sessions, 6 weeks). Relapse prevention. How to maintain change. Want patient moving towards BMI of 19-20. |
Fairburn's for BMI < 17.5 | adds emphasis upfront on regaining weight ->necessary for cognitive work & attendance at therapy. Goal: 1 pound per week = extra 500 calories/day. If BMI<15, refer to inpatient program. DO NOT see outpatient. |
Family Based Therapy For Anorexia: Phase 1 | Phase 1 Weight Restoration: Assist parents in re-feeding the child. Coach parents to validate ambivalence while insisting starvation is not an option. Externalize symptom: problem isn't the child, it's the disorder. Align child with siblings. |
FBT: Phase 2 | Return control back to adolescent. Parents help child take control over eating again.Day-to-day issues or family tension can be addressed. Coach on age-appropriate limits. |
FBT: Phase 3 | Establish healthy adolescent identity. Once adolescent maintains weight above 95% of ideal weight. Focus on impact AN had on establishing healthy identity. Autonomy, parental boundaries, preparation to leave the nest. |
Evidence for FBT | Best for adolescents who have been sick for <3 yrs. Return to normal weight after tx & maintain at 5 yr follow-up. ED symptoms improved more with FBT than with adolescent-focused tx |
CBT vs Meds | CBT+meds work better than meds alone. CBT=meds in immediate decrease in binge freq. CBT has greater magnitude & lasts longer than meds. Improved mood, concentration, sense of control, fewer concerns about shape & weight. |
