Will you need weekly sessions, more than once per week sessions, or can treatment be provided every other week? 

Typically, treatment sessions are scheduled once per week. If the symptoms are especially severe, then sessions may be scheduled more than once per week. Also, if you are unable to work because of your problem, sessions may be scheduled more frequently to assist you in returning to work as quickly as possible. Once treatment is under way, and you are experiencing some relief, you may be able to schedule appointments every other week, if weekly sessions pose a difficulty.

This should be discussed with your psychologist to assess whether it is appropriate. Near the end of treatment, some psychologists will taper the sessions gradually,  instead of abruptly ending treatment. That will depend on your individual circumstances.
