Note: Descriptive statistics reflect scores for participants included in the multitrait scaling analyses and not the entire study sample.
The SF-36v2 scales are normed to national data and have a mean of 50 and a standard deviation of 10, with lower scores reflecting poorer quality of life and higher scores indicating better functioning.
The HHIE/HHIA Total Score has a possible range of 0 to 100, with higher scores reflecting greater hearing handicap and lower scores indicating better functioning.
This subscale has a possible range of 0 to 52; higher scores indicate greater hearing handicap.
This subscale has a possible range of 0 to 48; higher scores indicate greater hearing handicap. SD = standard deviation.
