 Schilder was promoted to professor in 1925, and in the same year he released his "Abstract for psychiatry based on the principles of psychoanalysis".Because of his analytic commitments the academic establishment became increasingly hostile towards Schilder, and in 1928 he left the clinic and traveled to Baltimore where he became a guest lecturer for a semester at Johns Hopkins University.In 1929 Schilder undertook a lead role for the treatment of outpatients with psychoses for the WPV.
