Important Note:
IWQOL-Lite Scoring

In order to be able to compare your results to those of other studies, it is important to score the IWQOL-Lite correctly (i.e. convert raw scores to transformed scores on a scale of 0-100, where 100 represents the best quality of life.)

Raw scores are no longer used for reporting.
 
Early research on the IWQOL-Lite (Kolotkin et al. Obesity Research, Vol 9., No. 2, February 2001, pp 102-111) reported results in terms of raw scores, where higher scores indicated greater impairment in quality of life. Scoring changed in 2002 (Kolotkin et. al, Obesity Research, Vol. 10, No. 8, August 2002, pp 748-756) to the use of transformed scores ranging from 0 to 100, with 100 representing the best and 0 the worst quality of life.
