From the beginning, interpretation has been central to psychoanalysis. For Sigmund Freud, Anna Freud, and Melanie Klein the analytic model was about analysing, and you analysed by interpreting to the person what was behind his or her behaviour. This early and rather crude view of interpretation has been refined over the years. The refinement has led to many different schools of thought as to how interpretation should be used in the therapeutic encounter. These differences involve the questions of what, how much, and when an interpretation should be given.
