    I really enjoyed the paper, thank you. It mentions that further study is needed, is this on the cards? I also wonder how one would evaluate the quality of insights developed for coaches and trainers of coaching if Clean Language Interviewing, (CLI), was compared with a different form of qualitative interviewing?

    Yes, Bruce, there is more research to be published hopefully next year but on a parallel topic: a comparison of expert-assessor ratings of coaches, the coaches' self-rating, and the clients' evaluation of the session (described in a Clean Language interview). We examine the whole notion of 'competency' assessment.

    On your second point, "quality of insight" would be a difficult phenomenon to measure/assess, especially since, for me, it needs to be related to outcome. While clients almost always rave about the insights gained in a coaching session, "insight doe not equal foresight". I like to know what effect in the person's life the insight has. I'd put money on the relationship between the two being non-linear. In other words, a 'small' insight could lead to a 'big' effect, and vice versa. In which case, how to define the "quality" of an insight?

    Some of Jonathan Lloyd's PhD research was on the richness of data gathered in a CL interview compared to more traditional methods. He concluded "The profound findings that Clean Language, focusing on memory and metaphor, can increase the resultant amount of meaning by a factor of five." (The Use of Metaphor in Counselling and Qualitative Research Interviews, 2011, available at

    Do let me know if you find anything on the subject of relative quality of insights.
