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
- If one item is left unanswered this is scored 0 and the scores are summed and expressed as usual out of the maximum score.
- If two or more items are left unanswered the questionnaire is not scored.
- If two or more response options are ticked for one item, the response option with the highest score should be recorded.
- If there is a response between two tick boxes, the lower of the two score options should be recorded.
- 50% response for each domain is required in calculating the score for an individual patient.
Validation
Aspects of measurement properties completed include:
- Content validity
- Factor analysis
- Internal consistency
- Rasch analysis
- Test-retest reliability
- Reproducibility
- Face validity
- Cross validation with other measures
- Responsiveness
- Score banding
- Minimal clinically important difference
