Study Suzuki et al. (2014) in Pearson Edexcel A Level Psychology through schizophrenia, nutrition measures, inpatient samples, controls, validity and generalisability.
In your studies of schizophrenia you will have learned about the contemporary study by Suzuki et al. (2014).
Explain two strengths of Suzuki et al.'s (2014) study.

AO1 (2 marks) AO3 (2 marks)
Credit one mark for accurate identification of each strength (AO1)
Credit one mark for justification/exemplification of each strength (AO3)
For example:
- Suzuki et al (2014) conducted their research with inpatients during
actual, real life hospitalisation due to schizophrenia (1). There is a
high level of ecological validity as the setting was a real life situation
making it valid to Japanese schizophrenic inpatients (1).
- Reliability of the results about nutritional status of schizophrenic
inpatients is increased by supporting evidence with consistent
findings (1). Kitabayashi et al (2006) found similar results with a
higher frequency of underweight inpatients with schizophrenia in all
age groups than in the normal population (1).
Look for other reasonable marking points.

Explain one weakness of Suzuki et al.'s (2014) study.
(2)
AO1 (1 mark) AO3 (1 mark)
Credit one mark for accurate identification of a weakness (AO1)
Credit one mark for justification/exemplification weakness (AO3)
For example:
- Suzuki et al (2014) did not control for eating behaviours and
exercise in their sample of schizophrenic inpatients, both of which
can affect the participant's weight (1) so there may be
extraneous/confounding variables affecting underweight or obesity
data that reduces the reliability of the results found about
underweight schizophrenic patients (1).
Look for other reasonable marking points.
