The Medical model (mental illness criterion)Psychopath, diagnosis based on clinician, diagnostic manuals.
Medical Model evaluationBeing diagnosed as “sick” means you are not responsible for your acts
Most mental disorders cannot be linked to your brain
Deviation from social normsUndesirable or anti-social behavior, viewed by the majority of people in a given society.
What is seen as "Normal"Social, historical, and cultural factors play a role
Deviation from social norms evaluationCriteria is not objective or stable (views can change over time)
Could lead to discrimination against those that are different from the majority
Culture-bound syndromes (Zhang 1998)
The Mental Health Model of normality (Jahoda 1958)Criteria for what might constitute normal psychological health (no stress, mental illness, healthy relationships, realistic, independence).

Ethical considerationsCorrect diagnosis and treatment
Bias in diagnosis (gender, ethnicity, age).

Etiologies (causes) of one eating disorder

Question Answer
Kendler (1991)Twin research to study genetic vulnerability in bulimia nervosa
ProcedureA sample of female twins participated in the study. One twin of each pair had bulimia.
Type of studyLongitudinal (over time) study and researchers conducted interviews to see if the other twin would develop bulimia and if concordance rates were higher in identical or fraternal twins.
ResultsConcordance rate higher for identical twins.
EvaluationResults show a heritability of 55% but this leaves 45% for other factors.
Genetic vulnerability might develop bulimia, but other factors trigger the disorder.
Environmental factors not taken into account (dysfunctional environment could have been a trigger.)
Findings cannot be generalized (gender bias).

Cognitive and sociocultural factors

Question Answer
Fallon and Rozin (1985)Many patients with eating disorders suffer from the cognitive delusion that they are fat.
Procedureshowed nine pictures of different body shapes, from very thin to very heavy, to both sexes in the United States
People were askedindicate the body shape most similar, like their ideal body shape, and the body shape of the opposite sex to which they would be most attracted.
WomenChose heavier than their own bodies for their most similar and a much thinner body shape for their ideal (their perception caused them to lose weight).
MenChose closer to their own shape (satisfaction).
Jaeger (2002)Body shapes represented in the media could encourage dissatisfaction with body shape and lead to dieting behavior.
Sociocultural ideals caused Europe and Mediterranean women to diet.

Rosenhan

Question Answer
Rosenhan (1973)Being sane in insane places.
AimTo test reliability and validity of diagnosis in a natural setting. Can psychiatrists distinguish between abnormal and normal behavior?
ParticipantsCovert (not a secret) participant observation with 8 participants (5 men, 3 women).
ProcedureParticipants went to twelve hospitals in the US and stated that they were hearing voices.
ResultsAll pseudo-patients admitted and all but one diagnosed with schizophrenia.
All pseudo-patients behaved normally while hospitalized because they could only get out if the staff perceived them to be well.
Pseudo-patients took notes (this was actually interpreted by the staff as a symptom of their illness)
LengthIt took 7 to 52 days before patients released and labelled “schizophrenia in remission”
Follow-upStaff at a hospital told they were being sent pseudo-patients.
41 identified as imposters by at least one staff member, but no imposters actually sent.
Reveals issues with validity and reliability of diagnosis.
EvaluationRevision of diagnostic procedures. The development of diagnostic manuals have increased reliability and validity of diagnosis.
Ethical issuesStaff members were deceived in both studies.
In the second study, actual patients may not have received proper treatment because the staff was looking for imposters.
