How much time does psychoanalysis take? The duration of psychoanalytic treatments from Freud's cases to the Swedish...

The starting point for this paper is Freud's thinking about the length of psychoanalysis and the conditions for ending it. His psychoanalytic treatments were intense, but varied greatly in length. Freud's assertion that deep psychological changes take time is still topical; however, the length of time has gradually increased. Available documentation from psychoanalytic training institutes, and findings from empirical studies, indicate that the mean length of psychoanalysis ranges from between three to seven years, and varies between different countries and periods. A recent survey among Swedish psychoanalysts found a mean length of 5.7 years and a wide variation in length from 1.5 to 12 years. Discussions in a seminar group on endings and the qualitative follow-up survey showed that a unique combination of factors determined the duration of psychoanalysis in each individual case. We briefly review the potential determinants of the treatment length and the different meanings of time in open-ended psychoanalytic treatments. To conclude, we stress the need for systematic clinical and empirical studies of determinants and the underlying processes behind the different lengths of psychoanalyses.
