Raw scores are no longer used for reporting IWQOL-Lite scores
In order 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.)
Although early research on the IWQOL-Lite reported results in terms of raw scores, where higher scores indicated greater impairment in quality of life [Kolotkin, R.L., Crosby, R.D., Kosloski, K.D., and Williams, G.R. Development of a brief measure to assess quality of life in obesity. Obesity Research, 2001, 9 (2), 102-111.], scoring changed in 2002 to the use of transformed scores ranging from 0 to 100, with 100 representing the best and 0 the worst quality of life [Kolotkin, R.L., Crosby, R.D., Williams, G.R. Health-Related Quality of Life Varies Among Obese Subgroups. Obesity Research, 2002, 10 (8), 748-756].
