I think there is a great relationship between the two. The purpose of case conception is to analyze patients 'psychological activities by collecting information. In fact, the purpose of Freud's psychoanalysis is also to explore the psychological activities of patients. There are also theories of explanation in psychoanalysis, such as Freud's "stage of sexual psychological development", Adler's "inferiority complex" and so on. But "analysis" in psychoanalysis is to explore the psychological activities of patients, and case conceptualization is also the purpose. So, case conceptualization is inspired by psychoanalysis. Because psychoanalysis has not been recognized by the mainstream academic community, but psychotherapy is inseparable from "analysis", so, just like "the repressed desire is expressed in other ways", psychotherapy has invented "case conceptualization", case conceptualization is a psychoanalytical apprentice. What about you? What do you think of the relationship between the two? By the way, my "psychological analysis" is also an apprentice of psychoanalysis. In fact, the case conceptualization is a psychological analysis.
