Check that understanding with the client if unsure. Treat the client with the utmost respect and regard . The therapist knows themselves and is willing to be known. CCT may sound simple or limited, because there is no particular structure that the therapist is trying to apply. But when I watch CCT in action I see a very rich and complicated process.
People unravel their own stuff.
They discover new things, take brave steps, and don't have to cope with a therapist who is doing things to them in the meantime. The therapist strives to understand and accept the client's stuff, which is no simple feat. Over time, the client increasingly seeks to understand and accept their stuff too. That CCT is effective has been amply demonstrated by decades of research. Furthermore, recent research has shown that the most significant variables in the effectiveness of therapy are aspects of the relationship and the therapist's personal development - not the particular discipline they practise or techniques they employ.
