Ultimately, the best evaluation of a therapist’s worth is YOU. If you believe you are getting good service and find your relationship with your therapist helpful overall, then it probably is. If you have a nagging feeling that something just isn’t right between you and your therapist, listen to it. Talk with your therapist about this. If you and your therapist discuss your feelings and that voice is still nagging you, perhaps you need to find another therapist that suits your needs better.
The styles between therapists are going to be very different. Each individual therapist will favor the type of therapy that he/she uses over other theories, but it doesn’t mean that one is better than the other. Studies of the different schools of thought in therapy, the different “theoretical orientations”, show that it isn’t the theory your therapist believes in and uses in therapy that makes the therapy good, it is the relationship that you and your therapist build. If you have a good relationship with your therapist, you are likely to get more out of your therapy than if you don’t have a good relationship. The style your therapist uses may not make any difference to your experience of therapy at all.
