11 sons with schizophrenia
11 sons without
(lack of research support) Liem found what between the parents communication with schizophrenic and non schizophrenic sons?
communication was no more disordered
(lack of research support) Liem’s research caused him to question what?
cause or effect relationship
(lack of research support) does double bind cause schizophrenia or does?
schizophrenia cause double bind
(lack of research support) if the theory was correct what would you expect?
all/most children in the family to develop schizophrenia
(origins) to be a complete explanation what needs to be offered?
the origins of dysfunctional communications
(origins) Koopmans - double bind communication arises at times of what?
family disruption
(origins) Koopmans - what is there little evidence of?
empirical research support between disruption and double bind communication
(origins) Koopmans - there is also an ethical issue of what?
blaming patients/their families
(origins) it has been suggested double bind communications are a symptom of what?
mental illness/pathology
(origins) it may be pathology that is a greater issue than what?
communications
(origins) what does the lack of origins do to this explanation?
weakens it
(origins) Bateson didn’t claim double bind was a whole explanation rather he said it was what?
a risk factor
(EE research support) there is a lot of evidence to support the role of expression of emotion in what?
relapse of schizophrenia
(EE research support) Vaughan and Leff - in high EE homes with high contact and no medication, what was the rate of relapse?
90%
(EE research support) Vaughan and Leff - in low EE homes what was the rate of relapse?
10%
(EE research support) Vaughan and Leff - in high EE homes what was the rate of relapse?
50%
(EE research support) in prospective studies what were high risk children?
those with a parent with schizophrenia
(EE research support) high risk children who developed schizophrenia were more likely to come from where?
high EE homes characterised by negative relationships
(EE research support) Marcus - Israeli high risk study - none of the high risk children with good parenting did what?
developed schizophrenia
(EE research support) Kavanagh - people with schizophrenia in high risk families were how many times more likely to relapse than those in low EE families?
4x
(EE research support) not all research supports EE as a predictor of what?
relapse
(EE research support) McCreadie and Philips failed to find what?
increase in 6 and 12 month relapse rates among individuals with schizophrenia living in high risk homes
(EE research support) McCreadie and Philips research suggest although EE may be a significant relapse factor in some, it is not what?
the only one
(genes or environment) what is it difficult to separate?
whether it is the result of families having the same genes or same environment

genetics
(genes or environment) it may be dysfunctional communication is what?
