Scores represent the percentage of total possible score achieved. After this, items in the same scale are averaged together to create the 8 scale scores. The eight health concepts are: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions.
