when i was going twice a week, i had one session for 60 mins and later requested if we could have the second session for 90 mins. what a difference having a 90 min session made in my progress! we could actually spend time getting into the nitty gritty of some of my issues and have time to get me grounded before leaving. plus it usually did not feel rushed (i dreaded feeling like i was being booted out the door just as i was starting to become comfortable and opening up about something). the last year of therapy i chose to cut back down to once a week and i kept the 90 min session because it felt too valuable to give that time slot up.
