The London Handicap Scale can be used to determine the effect of chronic disorders on a person's functional ability using a self-completion questionnaire. The authors are from the Royal Free Hospital in London.
Development:
(1) Each degree of handicap along a 6-point interval was assigned a scale weight.
(2)The scale weights were assigned using conjoint analysis, with the derivation process described on page 12.
Parameters:
(1) mobility: "getting around"
(2) physical independence: "looking after yourself"
(3) occupation: "work and leisure activities"
(4) social integration: "getting on with people"
(5) orientation: "awareness of your surroundings"
(6) economic self-sufficiency: "affording the things you need"

London handicap scale =
= SUM(all 6 utility values) + 0.456
where:
• The sum of all "no disadvantage" values is 0.544, which when added to 0.456 gives 1.00.
• The sum of all "most severe disadvantage" values is –0.456, which when added to 0.456 gives 0.00.
Interpretation:
• minimum scale value: 0
• maximum scale value: 1.00
• The scale value corresponds to residual function, with 1.00 indicating normal function and 0.00 indicating total disability.
Performance:
• Pearson's correlation coefficient between predicted and measured values: 0.98
• Kendall's coefficient of concordance (tau): 1.00
