case study (Luk and Agoha) Flashcards
case studies
AO1
-To gather info on different disorders
-Takes an idiographic approach as focus on individual
-In-depth analysis of experiences and influences of psychological processes
-This is often done through methods such as diagnostic interviews, ppt observation, medical records, diaries
-Methods to analyse such data are often thematic analysis, grounded theory, and other text interpretation
-Most of the material and data collected is qualitative
case studies
strengths (5)
reliability
validity/ ecological validity
application
ethics
1) High reliability in the use of triangulation as it allows to show how data is consistent
2) High validity due to triangulation of data allowing for a range of measures to verify each other making conclusions more credible
3) High ecological validity due to ppts being assessed in environments natural to them therefore their behaviour will also be natural
4) High application as they provide insight in to disorders and how they affect people and their real life behaviour which can lead to new treatments to help
5) High ethics in clinical case studies as psychologists take care to follow HCPC guidelines to ensure protection from harm for the vulnerable groups being studied.
case studies
weaknesses (4)
generalisability
reliability
validity
1) Low generalisability due to studying a single ppt or small group with unique circumstances or details of their disorder that is hard to generalise to a wider population
2) Low reliability due to a unique case that is not likely to occur again and so data found cannot be compared easily due to lack of other data
3) Low validity due to studying patients closely in which researchers would likely form a bond with them therefore they may be subjective in their interpretations of behaviours so hard to avoid researcher bias
4) Low validity due to clinical interviews used providing descriptions of symptoms of the disorders in which a patient may not disclose all info and so their diagnosis may not be accurate
define triangulation
the use of a variety of data sources, including time, space and persons, in a study.
define idiographic
focusing in detail on a topic and on individuals.
define nomothetic
Looking for general rules in behaviour by drawing on data gathered that on large numbers.

Luk and Agoog (2014).
Describe the aim of this study.
To describe the experience of a Chinese-American adolescent girl with anorexia nervosa from multiple perspectives of theories, with a focus on cultural.
describe the procedure.
how old was she when admitted into the inpatient child psychiatric unit?
how many months later was she discharged?
how many more times was she readmitted in 6 months?
what happened on her 3rd admission?
-case study using retrospective data of chart reviews from when Amy was 15 and admitted to the inpatient Child Psychiatric unit for further care with a BMI of 11.8
-she suffered body dysmorphia, amenorrhea, and cold intolerance
-she underwent individual therapy, group therapy, daily weigh-ins, and monitoring of meals.
-she was discharged 3 months later but got readmitted 2 more times in 6 months due to not maintaining body weight.
-on her 3rd admission Amy was assigned a in-home therapist of the same culture who visited regularly to help with tension during family meals.
-visited China 10 months post-discharge and discontinued the fluoxetine while there.
describe the results
what was the main cause of her eating disorder?
what did the therapist help with?
-found that the main cause of the eating disorder was due to an overbearing mother who wouldn’t cater to Amy’s dietary preferences.
-With the therapist help of balancing food options for Amy and reducing tension at family meals she started to gain more weight.
-After visiting China Amy remained symptomatic but still refused meals with her family.
describe the conclusions
-Amy’s anorexia was a result of rejecting her parents and their different culture not the desire to be thin.
-Visit to china improved her autonomy and relationship with parents who gave her more freedom that allowed her to develop her sense of identity.
