This is my own version of the extension of 5 modalities to 7, to include 'medical model' relating and archetypal relating (based upon Hillman's 'The Myth of Analysis'). Other therapists have suggested the intercultural level of relating as a 6th modality. This makes some sense (as cross-cultural relatedness is indeed essential), but I prefer to think of socially constructed influences and cultural contexts as operating throughout all the modalities, rather than separating them out into one modality. 'Medical model' relating was excluded from Clarkson's list, as it was implicitly (and in some ways correctly) seen as outside the frame of psychological relating, but it is certainly a kind of relating which clients do expect, and therefore needs to be included. Hillman's archetypal relatedness could be seen as overlapping with Clarkson's transpersonal modality, but for good, but obscure reasons I prefer to keep them distinguished.
