MobQoL-7D: Measuring health-related quality of life and calculating QALYs for people with impaired mobility

The MobQoL-7D outcome measure has now been validated and is available here . If you would like to use the MobQoL-7D, please complete the registration form (which contains licence terms).

The Mobility and Quality of Life 7 Dimension (MobQoL-7D) outcome measure offers a valid and reliable approach to measuring the health-related quality of life of individuals with impaired mobility. This novel health state classification system has been developed specifically to generate health state utility values and to measure patient-reported outcomes in the context of mobility impairment. We are currently developing a preference-based value set to allow QALY calculation using the MobQoL-7D – we anticipate that this will be ready by the end of 2021.

The MobQoL-7D contains seven dimensions of mobility-related quality of life: accessibility, contribution, pain/discomfort, independence, self-esteem, mood/emotions and anxiety. It is quick and simple to complete, and can be used in both research and clinical practice. At present the MobQoL-7D has only been validated for use in adults, however we are planning to develop a child version to also translate the outcome measure into other languages.

Is the MobQoL-7D outcome measure free to use?

The MobQoL-7D is free to use for non-commercial purposes. We ask that users complete the registration form so that we can keep track of how the tool is used. If you would like to use the MobQoL-7D for commercial purposes, please complete the registration form and a member of the research team will provide you with a quote.

How was the MobQoL-7D developed?

The MobQoL-7D was developed as part of the MobQoL Project. This project was designed to find out how mobility (or being able to get around) affects quality of life. The term ‘quality of life’ can mean lots of different things, such as happiness, life satisfaction and well-being. We interviewed lots of different people with impaired mobility to understand what quality of life means to them, and how mobility influences their overall quality of life. We used this information to develop a new outcome measure tool for measuring mobility-related quality of life, which we call the MobQoL-7D

Why was the MobQoL-7D developed?

Every year the NHS supplies over a million wheelchairs and performs over 160,000 hip/knee operations, so it’s important that the NHS can accurately measure the benefits of services like these. Our aim was to develop a new tool to help researchers and mobility aid providers to measure how these services affect quality of life. This will help to improve the care and support provided to people with mobility impairments. During our research, we developed the MobQoL-7D outcome measure and confirmed its reliability and validity through piloting. In the final stage of the project we will develop a preference-based scoring system for the measure.
