Scoring

The HM-PRO has 24 items in Part A and 18 items in Part B. Each question has three response options:

Part A
  • Not at all (score = 0)
  • A little (1)
  • A lot (2)
  • Not applicable

Part B
  • Not at all (score = 0)
  • Mild (1)
  • Severe (2)

The score range for Part A is 0-48 and for Part B is 0-36. The higher the total score, the greater the effect on a patient’s quality of life.

The items in the HM-PRO are divided into four categories (domains):

  • Physical Behaviour (the first 7 items, maximum score of 14)
  • Social Well-being (the second 3 items, maximum score of 6)
  • Emotional Behaviour (the third 11 items, maximum score of 22)
  • Eating and Drinking (the last 3 items, maximum score of 6)

The HM-PRO Part A score can be reported as a single total score HM-PRO A-total, score range 0-48.

The HM-PRO Part A score can also be reported as four separate scores:

HM-PRO Physical, score range 0-14

HM-PRO Social, score range 0-6

HM-PRO Emotional, score range 0-22

HM-PRO Eating/Drinking, score range 0-6

The HM-PRO Part B score can be reported as a single total score HM-PRO B-total (score range 0-36)

Interpretation of incorrectly completed questionnaires

There is a very high success rate of accurate completion of the HM-PRO. However, sometimes subjects can make mistakes

  1. If one item is left unanswered this is scored 0 and the scores are summed and expressed as usual out of the maximum score.
  2. If two or more items are left unanswered the questionnaire is not scored.
  3. If two or more response options are ticked for one item, the response option with the highest score should be recorded.
  4. If there is a response between two tick boxes, the lower of the two score options should be recorded.
  5. 50% response for each domain is required in calculating the score for an individual patient.

Validation

  • Internal consistency 
  • Rasch analysis
  • Test-retest reliability
  • Reproducibility 
  • Face validity 
  • Cross validation with other measures
  • Responsiveness
  • Score banding
  • Minimal clinically important difference
