Schizophrenia revision
Disturbed family backgrounds
Double bind theory- describe
Children who receive contradictory messages from their parents are more likely to
develop schizophrenia. For example a mother tells her child she loves him whilst
shouting. Prolonged exposure to these messages prevents the child from developing
a `internally coherent construct of reality'. In the long term this leads to
symptoms such as affective flattening, delusions, hallucinations, incoherent
thinking and alogia.
Double bind theory-evaluate
Tienari : showed that if children were adopted due to their parents
schizophrenia they were more likely to develop the disorder but only if
their adoptive family were classed as disturbed.
Berger : found that schizophrenics reported a higher number of double
bind statements than non schizophrenics but this may be unreliable as
patients recall can be affected by their schizophrenia.
Other research : found no difference in the state of schizophrenia
between patients who gave double bind statements and those who didn't
Expressed emotion- describe
This idea suggests that some families are always aggressive towards each other as
they express too much emotion. This causes more stress for a schizophrenic who
may have just started recovering from the disorder and the extra stress could
lead to a relapse.
Expressed emotion-evaluate
Iranian study : study in Iran found that overprotective and rejective
mothers were the main cause of a child's relapse of a child's schizophrenia.
This supports the expressed emotion theory as it shows that higher levels of
stress can cause relapses.
Other research : has found that you are 4 times more likely to suffer a
relapse if your family has high levels of aggression
Correlational : it is not clear if stress of looking after a schizophrenic
leads to high levels of expressed emotion or if the high levels of expressed
emotion are the cause of the relapse. This is because we can't be sure of the
real cause of the relapses.
