When you study a psychology case study, you will get to know three types of treatment approaches. They are the psychoanalytic approach, cognitive-behavioural approach, and humanistic approach. You must study the symptoms of the patient first and then choose an approach. Furthermore, you should describe the treatment sessions, the response, and the effectiveness of the treatment approach.
As you can see, it is all about observation and comprehending the situation of the patient. Moreover, you should never refer to your subject as “the client” in the psychology case study. And remember to provide a detailed account of the diagnosis.
