QRM Flashcards
Case studies
An in-depth investigation that involves a detailed study of a single individual, institution or event.
Intrinsic case study
case studies of interest purely for their own sake, where there is no need to generalise beyond the case researched or to attempt to build theory based on the conclusions.
Instrumental case study
case studies carried out in order to describe, explain or build a theory around a phenomenon that happens with some frequency. Findings are expected to have relevance to other case studies.
Strengths of case studies
- Good to investigate sensitive and complex issues that may not be able to be studies otherwise
- Useful for studying group processes within a social group
- The results may create new knowledge which challenge preconceived ideas and contradict established theories
Limitations of case studies
- Researcher bias could be an issue because the researchers own beliefs and ideas could influence data collection
- Generalizability is difficult
- Participant expectancy is a risk as the researcher and participants interact for long periods of time
Case studies: sampling techniques
Snowball and purposive are best suited to case studies as they involve specific criteria, where as other techniques, such as random, would have participants that do not fit the criteria.
¬ However, purposive sampling is very selective and would be biased by the researcher.
¬ Case studies can often be about sensitive topics; therefore, snowball is good as the participants are encouraged to join by someone they trust (eg a friend).
Case studies: participant expectations
¬ There is a risk of participant expectancy because the researcher and participants interact with each other for long periods.
¬ Sometimes participants can show demand characteristics if they guess the aim of the case study.
¬ Because there is so much data then this could reduce participant expectations.
¬ This can seriously affect the results of the study and should be carefully monitored by the researcher.
Case studies: researcher bias
¬ This could be a problem because the researcher’s own beliefs and ideas could influence data collection.
¬ The topic that the researcher has chosen may mean that they have preconceptions about the participants-intrinsic.
¬ Relationships may form between the researcher and participants; this can lead to subjective views. This could happen due to the usual longitudinal nature of a case study but also depends on the level of interaction.
Case studies: credibility
¬ A case study involves very in-depth information, collected over a longitudinal period.
¬ Therefore, the data collected can be seen as trustworthy as the researcher can taken a long time to investigate a very specific phenomenon, provided the researcher uses triangulation and reflexivity.
¬ This would suggest that the data is believable and reliable.
Case studies: triangulation
¬ This is commonly used in case studies; researchers often use many different methods to study a topic.
¬ Clive Wearing-observed, interviewed and took part in experiments.
¬ This allows the researcher to increase the credibility of there results and enables them to give a true picture of the phenomenon.
Case studies: reflexivity
¬ How ‘trustworthy’ are the results-how valid the results of a study are.
¬ A report of a study should state information about the researcher and any relation they have to the topic in question and to any participants within the study.
¬ Any of these factors should be noted if they could impact the results of the study.
¬ Using personal and epistemological reflexivity increases the credibility of results as it can reduce bias and increase trustworthiness of the data- another researcher should look over the study and see that there have been no large impacts on the study because of researcher relations.
Case studies: ethical considerations
¬ Informed consent: it is important to gain informed consent from participants, sometimes participants are unable to give informed consent themselves as they are vulnerable individuals.
¬ Protection from harm: it is important in case studies for the privacy and anonymity of the participant to be upheld and avoid exploiting and taking advantage of vulnerable participants.
¬ Confidentiality: this can be an issue in case studies as they are so specific and therefore it can be hard to hide someone’s personal details (eg Clive Wearing)- case studies usually involve individuals and there is often a lot of information about the participant therefore if the information is not keep confidential it will be easy to identify the participant and this may compromise protection from harm.
Case studies: generalisability
¬ These are not carried out with the purpose of being generalizable beyond the case researched.
¬ Because they do not occur with much frequency, this makes it hard to make comparisons.
Instrumental:
¬ Even though they are still very unique, sometimes these can be generalised to some extent.
¬ This is because the case study is designed to add further depth and information to existing theories.
¬ Therefore, they must be generalizable to some extent so they can be compared to other existing research to increase the credibility of the theory.
Semi-structured interviews
there is an interview guide giving themes to explore- questions to discuss. There is flexibility in order, wording and depth of questions. Questions can be open or closed ended questions.
Focus group interviews
: a group of 6-10 people are interviewed at the same time. A facilitator introduces the participants to each other, asks questions and leads group interactions. Supposed to be like in real life and discuss and respond to one and others statements. Gives a special dynamic to the group and generates rich data
Narrative interview
individual interpretations of the world and such narratives influence people behaviour. A mix of facts and interpretations of experiences often conducted like a real story.
- researcher asks questions which are open ended and allows the person being studied to lead the interview in the study rather than the researcher showing the way
Interviews: sampling techniques
↔ Sampling techniques best suited to interviews will depend on the topic being investigated.
↔ It is likely that purposive sample will be used as it is the most effective way of obtaining data which includes the most information and information that is appropriate to the topic under investigation. However, this allows for too much subjectivity and researchers bias and prejudices might bias the sample, decreasing credibility.
↔ If the topic is sensitive, then the researcher could use the snowball technique. This would allow them to gain participants difficult to gain through the other techniques.
Interviews: participant expectations
↔ If the participants guess the aim of the interview, then they may change their responses.
↔ Particularly in focus groups where participants may feel pressure to give a certain response
Interviews: researcher bias
↔ The research could use leading questions to guide the participant in giving the responses they want.
↔ Through inductive content analysis this can be prevented.
Interviews: credibility
↔ Researcher subjectivity could reduce the credibility of the results.
↔ If the researcher uses impartial questions and prevents from using leading questions or directing the participants in any way, then the data collected will be more credible.
↔ Use of method triangulation will increase credibility, comparisons can be made.
Interviews: triangulation
↔ Researchers can use method triangulation to increase the credibility of results.
Interviews: reflexivity
↔ Researcher should use reflexivity to identify potential biases that may affect results.
↔ Personal reflexivity-
↔ Epistemological reflexivity can be shown with the choice of interview method because depending on the choice of methods affects the type of data collected.
Interviews: ethical considerations
↔ In semi-structured and narrative interviews private and personal information can be revealed that the participant may not have planned on disclosing to the researcher. This may result in the researcher being told controversial information and so the researcher must decide whether to disclose the information to the authorities
Interviews: generalisability
↔ Interviews, in particular narrative and semi-structured, can be very person so therefore not very generalizable, however a large amount of interviews carried out on the same topic, can allow overall trends identified to be generalized to the wider population.
↔ Focus groups can be seen as more generalizable as they contain more people per interview and therefore have a larger variety of opinions and views on the topic.
