Of course, we would not be offering this service unless we believed in our processes and abilities. We are guided by the major clinical findings in psychological science over the last few decades to use the most effective models, techniques and strategies. There is a lot of agreement among these, and when there are multiple approaches, we select and employ varieties of therapy that are most suited to your unique circumstances.
It’s good to be concerned about the skill of the person you entrust with helping your relationship. However, outside of artificially-controlled research situations, there can be no meaningful scorecard to compare couples therapists, for these reasons.
Categorizing and rating couples’ problems is very complex. (Even with affairs, for example, some have said that there are 11 different types!) Moreover, the problems couples report (say, an affair) are typically different from underlying causes (say, attachment difficulties), and the choice of solution (say, an Internal Family Systems dialog intervention) is often only one of many possible. Thus, situations and personalities are extremely varied, and will also affect which of many methods and interventions is appropriate. No one therapist or technique fits all, and those that fit most people will not necessarily fit you. In fact, the value in our service is that we apply the principles and techniques appropriate to your unique situation, not just the one in hand.
Some therapists attract or take on more difficult or complex cases than others, so any outcome measure would have to take that into account. There is tremendous variation in the readiness, ability and willingness of individuals to make a relationship a success. Therapy is not something done to you, but something done by you.
It is impossible to track long-term outcomes of all cases. Clients drop out of therapy for many reasons, and often don’t respond to invitations and inquires about how they are doing. It would be invasive of their privacy to insist that they do. (However, we do invite comments for our continuous improvement during therapy and at the conclusion.)
There is no agreed definition and measure of success. For a couple to remain together is not necessarily the best outcome. Who is to say that one future is better than another, if both cannot be fully known? Moreover, individuals may vary in level of satisfaction, given the same situational result. However, our service is designed to make the most out of your current relationship.
Therefore, any clinician who quotes a personal “success rate” is oversimplifying for marketing purposes, and that information would not be useful.
