Question

Quizplus · Accepted Answer

Improving the content validity of the instrument being used is not a way to control rater bias, as content validity refers to whether the items on the instrument are measuring what they are intended to measure, rather than the potential for raters to introduce bias in their ratings. Clarifying terminology, providing practice sessions, and comparing ratings of new and experienced raters are all strategies that can help control rater bias.
