L11 - Eating Disorders 2 Flashcards
What are individual risk factors?
- Negative body image
- Internalisation of thin idea
- Personality factors
- Neurocognitive impairments
- Dieting
- Negative emotionally
What was a study about negative body image and internalisation of the thin idea?
- 57 Undergrad women and 33 undergrad men
- Ppts completed a questionnaire of abnormal eating behaviours
- Rated their current appearance, ideal appearance, what they thought was most attractive to other sex, and the other sex they thought were most attractive
- Those with high abnormal eating had a spread out scale whereas those with low abnormal eating had a less spread scale
What are personality factors in Eds?
- Characterised by high-levels of perfectionism, which endures after recovery and appears to be familial
- Potential mechanisms include self-validation, rumination, and negative affect and escape when unmet high standards
What are the limitations of perfectionism and Eds?
- Most studies cross-sectional and do not have long term follow-ups, recruitment from treatment settings only
- Limits generalisability of findings and understanding of causal relationships
What are the neurocognitive factors?
- AN is strongly associated with Obsessive-compulsive thinking style, perfectionism and difficulties with social communication
- Difficulties may be an intermediate phenotype triggers by a specific neurocognitive profile
- Adults with AN show poor set-shifting and weak central coherence
- Weight restored individuals show intermediate and attenuated profile, unaffected relatives show similar profile, suggesting genetic component
What was the study looking whether children and adolescents with AN experience the same cognitive processing profile?
- Looked at ppts with anorexia nervosa and controls
- Neuropsych tests including IQ, Set-shifting, Central Coherence and Global Processing
- Self-report questionnaires including autism quotient, OCD symptoms
- The AN and control groups did not differ in IQ
- AN group displayed significantly more perseverative errors on WCST and lower style and central coherence scores on the ROCFT relative to controls
- Suggest inflexible thinking style, stronger attention to detail and poorer global integration
- Cog processing difficulties could be underlying trait for AN
What are family influences in ED?
- Individuals with AN report that family dysfunction contributed to the development of their ED
- Parents beliefs about the desirability of thinness, dieting and good physical appearance
- Criticism of child’s appearance and weight strong predictor of BN symptoms
- Has led to recommendations for family therapy approaches
What are media influences?
- Body dimensions of models have become thinner over last few decades
- Influence of social media on body image/satisfaction
- Diet/weight normative content is increasing in media
- As women’s weight has increased over the decades, playboy and miss America have gotten thinner and thinner
What are peer influences?
- Girls who engaged more frequently in social media photo activities reported greater overvaluation of shape and weight, more body dissatisfaction and more dietary constraint
- Photo investment and manipulation and unique predictor of overvaluation of shape and weight and dietary restraint
- Relationship between social media and body related/eating concerns may be bi-directional and mutually reinforcing: those who have more body-related/eating concerns are more drawn to these appearance-related activities AND engagement in appearance-focused activities contributes to persistence of body-related/eating concerns
What was a study looking at Eating behaviours and attitudes following prolonged exposure to tv among Fiji Adolescent girls?
- Attitudes to body image changed drastically with the coming of TV in 1995 - American Teenage programmes
- Within 3 years, the no. of girls engaged in purging behaviours rose to 11% and a sig increase in scores on the EAT-26 scale
- Extensive qualitative research indicated a causal link
DO eating disorders only occur within specific cultures?
- Historical survey and meta-analysis conducted
- Found that BN only occurs within specific cultures but not AN - fits in with stronger genetic basis of AN
- Heritability estimates for BN show greater variability cross-culturally than AN
What are common treatments for AN?
- Emergency procedures to restore weight
- Antidepressants or other medications
- Family therapy
- CBT
What are common treatments for BN?
- Antidepressants or other medications
- CBT
What are targets for CBT?
- Encourage healthy eating and reaching healthy body weight
- Create a personalised treatment based on processes that appear to maintain the eating problem
- Includes self-monitoring of the dietary intake and associated thoughts and feelings
- Cover nutrition, cog restructuring, mood regulation, social skills, body image concerns, self-esteem and relapse prevention
- Enhance self-efficacy
What are family-based treatment?
- Specific treatment for ED that involve the full family
- Parents/carers empowered to support their child’s recovery
- No blame: ED is seen as separate from the patient and externalised
- Importance of early intervention
