Advantages and disadvantages of case study method in psychology

However, there are times when multiple cases are studied. When the latter is the cases, the principle of replication is hinged on when choosing the cases to include. The case study must at the end have some vivid and clear advantages and disadvantages, and it must give results that are valid and reliable so that future research can be developed from the study.

They are being deemed non-scientific and of questionable usefulness. In this blog I will look at both sides of the argument for case studies and see whether as a design it is still useful for the field of psychology.

Advantages Case studies allow a lot of detail to be collected that would not normally be easily obtained by other research designs. The data collected is normally a lot richer and of greater depth than can be found through other experimental designs.

Case studies tend to be conducted on rare cases where large samples of similar participants are not available. An example of this is the study of Phineas Gage by Harlow, J. This example also connects with the point above with the depth of data obtained.

Cases of brain damage are quite minimal and it is extremely rare to find people with the exact same parts of the brain affected.

Advantages and Disadvantages of Questionnaires

To be able to gain knowledge of brain functions the damage between people have to be exact to ensure you are testing the right thing, this can generally only be done through case studies.

Within the case study, scientific experiments can be conducted. Case studies can help experimenters adapt ideas and produce novel hypotheses which can be used for later testing. Again to Phineas Gage, his contributions to neuropsychology and the workings of the brain are invaluable.

Disadvantages One of the main criticisms is that the data collected cannot necessarily be generalised to the wider population.

This leads to data being collected over longitudinal case studies not always being relevant or particularly useful. Some case studies are not scientific. Freud used case studies for many of his theories or studies. Such examples are that of Anna O and Little Hans. Both of these are not scientific nor are they able to be generalised.

This can be attributed to them being case studies, but also Freudian theory in general. Case studies are generally on one person, but there also tends to only be one experimenter collecting the data. This can lead to bias in data collection, which can influence results more than in different designs.

Case studies also tend to collect mainly qualitative data. I have put this as neither an advantage or disadvantage of case studies, as this depends on your stance on qualitative data.

If you look back a few blogs I have summarised my view of qualitative data. It would be extremely unethical to go taking parts of peoples brains out just to make a larger sample size to use a different experimental design method.

However, as data is collected on new cases I think it is important to always refer back to previous data in order to build on existing knowledge and ensure findings are as applicable to real life as possible.Aug 18,  · You have pointed out lots of advantages and disadvantages of case studies, there are also ethical issues, observations and interviews are typically used in case study research to gather data, so the ethical issues are broadly the same (e.g.

privacy, consent, risk of harm, etc). 1. The questionnaire has great potentialities when it is properly used.. 2. It is an economical way of accumulating information of significance from international marketer..

3. When the respondents are scattered far and wide, it will be a better tool as compared to the tools like interview or observation. Start studying AP Psych - Research Methods - Advantages and Disadvantages. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

Case Studies in Psychology

Case Study Following a single case, typically over an extended period of time Can involve naturalistic observations, and include psychological testing, interviews, interviews with others, and the application of a treatment or observation.

Case study method is responsible for intensive study of a unit. It is the investigation and exploration of an event thoroughly and deeply. Strengths and Weaknesses of Case Studies.

Advantages and Disadvantages in Real-Life Studies. Two of these case studies are the Tylenol Scandal and the Genie language study. Advantages and Disadvantages of Case Studies A first step in identifying the advantages and disadvantages of case study method is to clarify the major attributes of this research strategy.

Normally, a definition would be expected to specify such boundaries.
