The most common frequency is once a week.

But there are times when two or more times per week could be appropriate, especially if the issue is acute and serious, or if the goal is to provide therapy in a condensed format for a reason like someone is preparing to go away to college, etc.

There are also times, when going every other week or once a month could make sense. I often taper clients to this kind of schedule after symptoms have been significantly reduced and the client has learned the skills to cope better on his or her own.
