It depends on how serious the problem is and what the client wants to achieve. We usually start with a 50 minute session with follow up visits every week or every other week. Again, depending on the issue, some people like to check in every couple of months.
Treatment plans vary. For instance, some issues may take just a couple of sessions, relationship and workplace issues will take longer and very serious problems may require a plan for continuing support. The Medicare Rebate allows for 10 sessions per calendar year which is probably more than most people require.
