Answer:
psychodynamic (psychoanalysis and following theories)
Step-by-step explanation:
For Freud and his followers, all adulthood and late problems with behavior
are deeply rooted in our childhood experiences:
Psychodynamic theory sees events ocurring in early childhood years as a great source of shaping for lives and personality of individuals. Negative or hard to understand events happeningi in childhood can remain repressed in the unconscious mind and manifest later as adults.

He first proposed psychoanalysis as the main theraphy for tacking these.
