In my opinion, diagnosing a patient goes completely againt the core conditions that CCT offers. So, perhaps it is not a matter of being confused but just disagreeing on the way CCT is practiced.
However, I would still argue that if one is ecclectic, they cannot practice CCT. CCT is is non-directive approach. Playing with other approaches would not help a therapist to keep a CCT approach. I don't think. It is too easy to "play with tools" with other approaches, why would you then just use the 6 core conditions suddenly? CCT is not a tool, it is an attitude but if you use it as a tool (sometimes CBT, sometimes CCT because I want that silence here or there or show some empathy), then this is not CCT, this is just instrumental, which is far far away from what Rogers wanted to communicate about therapy and his 6 core conditions.
it is not about being flexible neither. Just be yourself. In fact this approach is first very complex, however if it suits your personality like a glove, it is the easiest to practice. If it is you, and when it is you, you've got everything with CCT because a CCTherapist is non-directive yes clients can choose to speak or play whatever they want...and the CCT will follow surely...but the tools are nothing compared to being deeply empathic and when clients start realising that, they want nothing else... it feels good to be with someone who can really listen, be empathic, non judgemental and on the same wve length...
When you sayI am just saying that starting analysing "a problem" and trying to get rid of it or solve it is not CCT, being ecclectic takes you away from being yourself
