Nine experts rated the content validity of each test in relation to the 5 tasks in the rating protocol. The item content validity index, and the scale content validity index were determined, and a kappa rating was calculated. Three of the 74 items on the CHFHC were determined to be not relevant receiving a content validity index of 0.78 or less. All of the items were ranked as being quite clear or highly clear, with all items receiving at least 0.78 on the content validity index. The Kappa score indicates expert agreement.
