Minimal Important Difference (MID) and Effect Sizes for the measure’s domains now available

The developers of the generic patient reported outcome (PRO) measure, the Oxford Participation and Activities Questionnaire (OxPAQ), have recently published† data presenting Minimal Important Difference (MID) and Effect Sizes for the measure’s domains. These findings can act as guidance for those powering clinical trials assessing participation and activity and further supports the adoption of this new generic PRO measure.

 

Further information on the OxPAQ:

The Oxford Participation and Activities Questionnaire (OxPAQ) is a short, 23-item, patient-reported outcome measure developed to assess participation and activity in patients experiencing a range of health conditions. The Oxford Participation and Activities Questionnaire is a patient-reported outcome measure that is grounded on the World Health Organization International Classification of Functioning, Disability, and Health (ICF) and is fully compliant with current best practice guidelines, such as those published by the FDA. The Ox-PAQ was developed by researchers within the Health Services Research Unit, part of the Nuffield Department of Population Health at the University of Oxford. The Ox-PAQ also comes as an ‘acute’ version, with emphasis on the recall period being more recent; 1 week rather than 4 weeks.

The development of the OxPAQ was funded by the European Brain Council.
