I've wondered about this similarly with autism: people refer to their kids as being "on the autism spectrum". Isn't the point of modeling it as a spectrum that we're all SOMEWHERE on that spectrum, it's just that most of us are further in one direction. But there's no binary yes / no that guarantees certain approaches will work well for you. Some things work well for kids with serious cases of the associated disorders, but you might fight that the same approach works better for people who are struggling despite no autism diagnosis. I would think the real approach is to know many techniques and try varying them to see what works best for someone as an individual.
