The number of sessions that a person needs depends upon their specific problem, how long the problem has existed, and personal goals. For a specific and acute problem, short-term therapy can be adequate which is around 6 to 12 sessions. For problems and conditions that have been more chronic, more sessions may be needed.

For individuals wanting to gain insight and understating into their past and how it is affecting their current relationships, more long-term therapy is recommended. The length of treatment should be discussed within the first or second session to clarify the treatment plan.
