Cognitive-behavioral therapy combines methods from both cognitive therapy and behavioral therapy, and has been shown to be a very effective counseling approach.
Sometimes, CBT therapists will tell you that CBT is "proven" to work. The truth is that nothing is proven in therapy! But decades of research shows that people who participate in therapy for at least six months experience significant improvements in their lives, emotions, and overall well-being.
What we do know is that there are many types of therapy that can produce good results, but what really makes a difference is the quality of the relationship (therapeutic alliance) between the therapist and the client. In other words, when the patient knows that their therapist genuinely cares about them and their well being, they are more receptive to therapy and can benefit from whichever counseling approach the therapist uses.
So basically, be sure to pick a therapist you like and trust! And one that pays attention to feedback in counseling.....in the literature (research) on the effectiveness of psychotherapy, we call these therapists "SuperShrinks" - 20 % of therapist are actually responsible for 80% of quality outcomes in therapy.
