Hi Belle, thanks for the links, very interesting!
I think passthepotatoes makes a good point, it had not occurred to me that you could perhaps work with another person.
Also, I definitely think that some therapies for specific diagnoses can cross over to be effective for kids with similar issues - however misdiagnosing a child to get there doesn't make a lot of sense to me either. For instance, we are doing a little bit of counseling for my son, in both social skills training and also starting discussion with a therapist about negative thinking, and how to turn that around, work on 'resiliency', etc. The second article you link to talks a bit about gifted kids being more prone to having thoughts which in the normal population would be considered definitely depressive, for gifted kids it may be more 'normal', but still something to help them work through.
