The review was then performed by a team of experts made up of six judges. Out of the 24 items on the scale, most of them obtained an index of content validity above 0.78, except three which were then reviewed. The instrument was then carried out, being pre-tested by 35 informal caregivers of elderly people, six participants were in doubt about two questions "eight and twenty-four"; the doubts were clarified and, after that, there was clarity, understanding and acceptability.
