Hi Nick, NT is possibly the most useful and effective therapy approach for exploring the construction of self in early adolescence because it is based on a post-structuralist and social constructionist paradigm.
Michael White (1995, p. 15) offers us this:
"According to [a post-structuralist or non-structuralist] account, the fashioning of
identity is:
(a) a public and social achievement, not a private and individual achievement,
(b) shaped by historical and cultural forces, rather than by the forces of nature,
however nature might be conceived of, and
(b) dependent upon deriving a sense of authenticity that is an outcome of social
processes that are acknowledging of one’s preferred claims about one’s identity
and about one’s history, rather than being the outcome of the identification,
through introspection, of the essences or elements of the ‘self’, and of the
expression of the essences, however this self might be conceived of."
NT recognises the role of social interaction in constructions of the self, and so the therapist can intentionally encourage stories of identity, helping young people to thicken their preferred identities. Deleuze wrote that we are always becoming. Identity, and construction of the self is always already in movement from moment to moment. An understanding of identity as a shifting, multiplicity rather than a fixed 'personality' allows for CONSTRUCTION, rather than DISCOVERY.
My daughter is looking for studies on NT and teenage social anxiety disorder for her International Baccalaureate final-year extended essay. There don't seem to be many papers addressing both, so if you happen to know of any we'd be extremely grateful to you. So far we've found
