The duration of classical psychoanalysis therapy may last for:

Several years

The duration of treatment varies depending on the therapeutic approach and the specific needs of the client:

Classical psychoanalysis, a form of psychodynamic therapy, traditionally extends over several years. However, more recent versions of psychodynamic therapies have been developed, which are completed within a shorter timeframe of approximately 10 to 15 sessions.

Behavior therapy, cognitive-behavioral therapy (CBT), and existential therapies generally have shorter durations and are typically completed within a few months. These approaches tend to be more focused and structured, aiming to address specific issues and achieve desired outcomes within a relatively concise timeframe.
