Summary of patient feedback

General qualities	Patient feedback
Face validity	Patients felt most questions were relevant, easy to understand and answer. Patients tended to interpret the questions correctly as they were intended. Some queried if the MSK-HQ may be difficult for individuals with multiple MSK conditions, eg, ‘which condition do I talk about?’
Content validity	Patients considered that all items were highly relevant and important to their daily lives. Patients agreed that the MSK-HQ covered most prioritised domains they wanted. Other domains suggested included: Severity of and/or length of time with stiffness during the day and at night, Effectiveness of pain relief treatments/therapies, Impact on social activities, A general change in health question.
Recall period	Patients correctly used a 2-week recall period for most questions.
Response scale	All patients generally agreed that the response scale and descriptive responses were appropriate. The use of ‘extremely’ as the final response option was changed as it was not always appropriate.
Format and layout	Patients considered the layout and format to be appropriate. Some minor issues included: The MSK-HQ instructions and spacing of items, Response options descriptors should be close to tick boxes, Labelling of the items was improved. Patients did not generally notice the scoring codes for each item response. A few mentioned that they are used to see these on questionnaires and did not think that it was a problem having them included.
Sensitivity to change	Patients suggested that all domains were likely to change over time, depending on stage or severity of their condition: Domains most likely to change: walking, pain, sleep, physical activities and impact, Domains least likely to change: dressing and help needed.
Application and administration	Patients thought that the MSK-HQ would be useful to monitor health regularly. The generic nature of the questionnaire was mostly perceived to be a positive thing, so it can be used across different MSK conditions. Patients suggested that they would be happy to complete it themselves at home. Completion every 3 months was suggested as a suitable follow-up period.
