abnormal patterns of communication within the family
what are the components of family dysfunction?
double bind theory
expressed emotion
what is double bind theory
receiving conflicting messages
suggested by Bateson et al
children are more likely to develop SZ if they receive conflicting messages from their parents due to the childs ability to respond is incapacitated by the contradictions because one message invalidates the other
what symptoms does double bind theory lead to?
prevents the development of an internally coherent construction of reality which can lead to flattened affect and withdrawal
what is expressed emotion?
a negative emotional climate with high levels of expressed emotion
this can be through emotional over-involvement or over-concern or through a hostile approach to interacting
high levels of expressed emotion are more likely to influence relapse rates
what does expressed emotion lead to?
higher relapse rates (linszen et al)
lower tolerance for an intense environmental stimuli especially negative comments
leads to stress beyond coping mechanisms and triggers a schizophrenic episode
support for the importance of family relationships
demonstrated by tienari et als adoption study
it demonstrated that whilst children with sz parents were more likely to develop sz, this difference only emerged where the adopted family was rated as disturbed
suggesting the illness only manifests under certain environmental conditions + family dysfunction is important
support for the double bind theory
Berger
found that schizophrenics reported a higher recall of double bind statements by their mothers than non-schizophrenics
however, other studies eg by Liem found no difference of communication in sz families compared to normal
what is the value of double bind theory?
gibney argues it led to the development of family therapy
what is a negative of expressed emotion?
individual differences in vunerability
not all patients who live in high EE families relapse and not all patients who live in low EE homes avoid relapse
there are individual differences in stress responces to high EE behaviours
Altorfer et al found 1/4 of patients showed no responses to stressful comments from relatives
