Erik has been asked to carry out a cross-sectional study of patient’s behaviour in a psychiatric ward.
a) Describe how Erik may obtain his sample for his cross-sectional study (2 marks)
- Erik could have a sample of 30 random patients from the ages of 20 to 35. 2 years later Erik could get a sample of 30 random different patients aged 20 to 35 all to complete a questionnaire.
- Only uses the participants that are in the ward at the time.
b) Erik has been asked to collect primary data as part of his cross-sectional study.
Describe how Erik could collect primary data regarding the patient’s behaviour. (3 marks)
- Erik needs to decide whether he is going to write down the behaviours displayed by the patients he sees or tally them.
- Erik cans set up video cameras to record the patient’s behaviour.
- Erik may also sit down with a selection of patients and write down their experiences of being in a psychiatric ward.
c) Explain one strength and one weakness of a cross-sectional study.
Strength
- Quicker to conduct than longitudinal research studies
- because they use a variety of participants at one point in time rather than waiting to follow them through their life.
Weakness
- The participants are different and this causes participant variable
which means the conclusions made could be due to individual differences than between participants
Describe how the ICD is used as a classification system for mental health. (4)
- The ICD is a diagnostic system that includes all
diseases, physical and mental used by clinicians
to diagnose service users - If the service user presents with a possible mental health disorder the clinician would use the section that focuses on mental and behavioural disorders
- For each mental health disorder, it gives a clinician the main features and the symptoms needed to make a diagnosis
- for example, the ICD 10 states that paranoid schizophrenia is dominated by relatively stable, paranoid delusions, often with hallucinations
