There is unwritten rule that therapy sessions are 50-60 minutes in length. I prefer to meet with clients for 25 minute sessions. Shorter sessions are more focused, keep sessions from drifting into unhelpful, or unrelated topics, and put emphasis on the fact that what is done outside of the therapy session is what matters most. For that reason, I find it more important to add brief check-ins for accountability, and support. Another great benefit to clients with 25 minute sessions is that it keeps therapy more affordable.
