Interesting, but I am not sure it works as a universal way to assess who fits with whom best. For example "avoidant clients should be matched with an attuned, following, warm, flexible "holding" type of therapy"... Just reading this forum, I am not sure that the people who self-admittedly have avoidant tendencies (including myself) desire that type of therapist. For me, a T who overly tried to connect with me emotionally mostly just provoked increased avoidance. Intelligent, well-informed and realistic with good boundaries is a much better match. Maybe for the ambivalent style the firm, consistent and boundaried is a good fit - again, just reading this forum.
