Disagreements and misunderstandings between informal caregivers and care-receivers have been widely reported, but the causes are unclear. The present article compares the views of people with acquired brain injury and their main informal caregivers (28 dyads, n = 56).

Caregivers saw themselves as less confident, less intelligent, more embarrassed, more independent and more overprotective than care-receivers rated them to be.
