Case study Technique Essay Example for Free

Case examine Technique EssayIn psychological science, upshots regard is the use of descriptive research and abstract to obtain in-depth information about a person, group, or a phenomenon. Case study is conducted using techniques such as direct-observation of the person, personal interviews, psychometric tests, and use of earliest researches archived (Dunbar, 2005). Psychology uses a oddball study often in clinical research to explain an unusual occurrences and conditions of the patient. The conditions ar contrary to the pre-established principles in the fields of psychological science and clinical research. Most of the case studies are single-case design however, there is multiple-case design where instead of using sampling, replication is the criterion for use. Case study in psychology ought to be valid, and reliable to help in the future psychological research. This paper explains the reasons, disadvantages, and advantages of the case study.Reasons for Using Case StudyC ase study allows the researcher to go steady and gather information about persons in far more detail than if the research was on a large number of people. Although the case study is non a research method, clinical and psychological researchers identifies methods of data collection that is suitable for the case study (Goodwin, 1995). For instance, observation, interviews, personal notes, and officially documented ushers. The reason for the case study is to investigate into the private lives of persons with the focus of understanding them and helping them in overcoming the problems that they experienced in their daily lives.Advantages and Disadvantages of Case StudyCase study allows the researchers to collect detailed information about a person that is useful. The information would not have been obtained by the other research methods. The information obtained during the case study is richer and is greater in depth compared to the other experimental designs. Moreover, the research considers rare cases where large samples of similar people are not available. Scientific experiments on the person done during the affect of study are also an advantage (Dunbar, 2005). The process enables the researchers to adapt to ideas and come up with a hypothesis thatwill be a point of cite in the future research.On the contrary, the data collected during the case study cannot apply in a wider population. This makes the data not be useful in longitudinal case studies. In addition, some of the studies are not scientific in nature (Goodwin, 1995). They are only a generalization of the scientific principles. The study considers only one individual therefore, the study is prone to the researcher biases. The bias of the experimenter can influence the conclusions more than in the other study designs. It is also effortful to prove the effect from the psychological case study (Dunbar, 2005). A case study is often prone to be more sentence consuming than the time used in other study designs.Sources of Case Study DataThe case study research generates data from different sources. The researchers use field notes to record data that is already available in stored databases. The use of sampling where one person is examined to represent a wider group is also a method of case study data collection. In addition, questionnaires, observations, and interviewing are other methods used to collect case study data. In conclusion, the study tends to collect qualitative data. The psychological case study is important since it collects unique and in-depth data about a person. Mainly, the rare phenomena and conditions allude to case studies. Finally, it is vital to refer to the recorded data to ensure that the findings are accurate and applicable in the real life situations.ReferencesDunbar, G. (2005).
