The reading I did was for a paper and was online in the library. There is not an online link to it unfortunately but the stats I quote are from it. It's by Lambert and Barley called "Research summary on the therapeutic relationship and psychotherapy outcome" (2001). There's lots of material out there on the importance of the therapeutic relationship and also on the kind I do, relational psychoanalysis. Just thought it might be interesting to people who wonder about their therapy, how much is approach related, how much is the actual connection, and if they have curiosities about whether or not to bring up issues when the approach doesn't seem to let it come up, this is evidence that is pretty clear that the relationship has a big effect so is worth considering.
