Worked Solution & Example Answer:Andi is a clinical psychologist who is investigating whether family relationships improve or deteriorate once a person has been diagnosed with a mental health disorder - AQA - A-Level Psychology - Question 2 - 2020 - Paper 2
Step 1
Suggest one open question Andi may use in her interview about the influence of diagnosis on family relationships.
Answer
An appropriate open question could be: 'How has your relationship with your family member been affected by their mental health disorder?' This question directly addresses the influence of the diagnosis on family dynamics.
Step 2
State two reasons why Andi used the chi-squared test on her data.
Answer
- Andi was looking for significant differences in relationships between patients and families waiting for a diagnosis versus those who already had a diagnosis, which makes it suitable to use a chi-squared test for categorical data.
- The chi-squared test helps determine if there is a significant association between the two categorical variables: diagnosis status and family relationship outcomes.
Step 3
Explain whether Andi’s results were significant for a one-tailed (directional) hypothesis when p ≤ 0.01.
Answer
Andi found an observed value of 5.84 for her chi-squared test with df=1. The critical value for a one-tailed test at p ≤ 0.01 is 5.02. Since 5.84 is greater than 5.02, it indicates a significant difference in relationship quality based on diagnosis. Thus, Andi's results are significant for her one-tailed hypothesis.
Step 4
Explain one strength and one weakness of thematic analysis as used by Andi.
Answer
Strength: Thematic analysis allows Andi to condense large amounts of qualitative data into manageable themes, providing clarity and focus on key findings about family relationships.
Weakness: Thematic analysis can introduce bias if the researcher’s interpretation overlooks important themes, leading to a potential misrepresentation of the data, which might not fully capture the perspectives of patients and their families.
