True or false: It is important to involve the teenager as a partner in his or her care?

Answer 1

True
Not a lot of information here, but a teenager is 90% of the way to an adult, the involvement in their own care should have started to grow every milestone they passed. How are they supposed to survive on their own at college or their first place or job if they haven't had any responsibility in decision making for their own life.
If you are talking about health care than absolutely true, a person no matter what age has the most insight into their own recovery, any patient should be at the forefront of their recovery and never left in the dark.
I look at it like this, they make proposals and have discussions with parents, parents make final decisions.

Answer 2

Involve, true. Take over, in most cases, no. The teenager is almost an adult, and it would be good for him/her to be partner in the care, if for no other reason than the primary caregiver to be able to model how to advocate for their own care when they are an adult. How to ask questions, not just accept what you are told...these are important skills for a teenager to learn regarding decisions about their care.
