Scoring the CFQ-R
Items in the questionnaire are expressed either "negatively" or "positively," therefore a number of the items must be recoded before the scores for each of the domains are calculated. Please note that recoding instructions are provided for each method of scoring below (Handscoring, SPSS, or SAS).
The score is calculated by adding the score obtained for each item of a domain (scale), after any necessary recoding. Scoring for each domain can be computed only if at least half the items have been completed. If not, then the domain should not be scored and should be considered missing for that particular person who filled out the questionnaire.
The minimum or maximum score always corresponds to the highest QOL and the minimum score always corresponds to the lowest QOL.
The miniumum or maximum score for each domain depends on the number of items in the domain. The score, which is calculated for one domain containing two 4-level items, may range from 2 to 8 points. The score, calculated on the basis of five 4-level items, may range from 5 to 20. In order to compare scores between all domains, the scores are standardized: for each sclae the scores range from 0 to 100.
There are four different methods of scoring the CFQ-R. Please choose your preferred method of scoring. Each method describes how to recode items and obtain domain scores.
