People First in Scotland made an easy read book about this.
They talked to 120 persons with IDD.
One person said "I don't get other people to decide for me. I've got a voice."
Some also said that making decisions can be hard. They like to get help from others they trust.
They want to learn about options. They want to think about effects after a decision.
They said that guardianship should not happen unless all other supports were tried and did not work.
