You'd be missing out on the training to provide
psychoanalysis, which is a very specific type of psychodynamic therapy. I considered this as well and decided to pursue training in a specific type of psychodynamic therapy training (TFP). Most analysts I've observed are primarily engaged in supportive therapy. No one wants to do the hard stuff (e.g., sitting behind the patient for 3 months without talking!).
Reviewing this
paper helped. Even analysts are doing very little psychoanalysis. In my opinion, if you're going to offer twice-weekly therapy, shouldn't you be providing a therapy specifically designed for this frequency (such as Schema or TFP) rather than offering a "lighter" form of something completely different?
