Yes they should be he is the Godfather of Psychotherapy and all one can do is build upon what he has developed in the past. There still needs to be research done on how to improve the therapy for all types of people, problems and situations that there currently are working on.
Yes, Sigmund Freud's psychoanalytic theories should still be taken into account when developing new methods of psychotherapy, because he made a lot of points that are still correct. Freud was correct with some of his theories about mothers. It is important to remember the wise things he said, because they are the back bone of modern psychology.
Although Freud is very popular today, his theories have come into question. A lot of critics point out that he was sexist and his methodology was not always scientific by today's standards. Freud will remain a giant in the world of psychoanalysis, but his theories should not be used by medical doctors.
I definitely think that Sigmund Freud's psychoanalytic theories should still be taken into account when developing new methods of psychotherapy. I think that a lot of his old theories can still be valuable and useful despite a lot of the things that psychotherapists have learned today. It is important to use info wherever it is.
When psychotherapy was first being utilized, Sigmund Freud's psychoanalytic theory was almost the basis of it. And, as brilliant as it is, I do not think it holds water anymore going forward. We are much more advanced now than Freud was. This is like asking if one of Francis Bacon's phlisophies should be taken into account for physics. No.
