The Copenhagen Hip and Groin Outcome Score is a patient-reported questionnaire that has six discrete subscales to assess Pain (10 items), Symptoms (7 items), Physical function in daily living (5 items), physical function in Sport and Recreation (8 items), Participation in Physical Activities (2 items) and hip and/or groin related Quality of Life (5 items). It has 37 items in total. 
The objective of the HAGOS questionnaire was to achieve a quantitative measure in a young to middle-aged physically active patient who had hip and/or groin disability. HAGOS uses the framework of ICF in the questionnaire and thus looks at patients with a hip and/or groin disabilities by relation to impairments, activity limitation and participation restrictions.  For a patient to be considered physically active, they need to be active for at least 2.5 hours per week.
