A case study involves detailed research of an individual through methods including observations, interviews, diaries, personal notes and the health history of the patient, notes Simply Psychology. The gathered information is mostly qualitative and is analyzed using different established theories, such as interpretative phenomenological analysis or grounded theory, while focusing strictly on the individual case without using a comparison group. Such thorough investigation into a particular case also gives the practitioner an opportunity to the better understand the patient and their individual needs in an effort to better help the patient.
