I think it's helpful to remember, too, that there aren't hard and fast boundaries between theories as they function in a session. It's necessary to separate them for the purposes of study, but many overlap and cross-pollinate within a given treatment. Some are more congruous than others. My T certainly didn't practice traditional psychoanalysis, but his psychodynamic approach was largely influenced by psychoanalytic theories, especially Object Relations/Self-Psychology, and he often employed CBT approaches in specific applications. His umbrella perspective was developmental, which worked to shape his conception of treatment and could accommodate a variety of modalities as useful.
