OGI^™ 8.0 Questionnaire
Osteoarthritis Global Index

The OGI^™ 8.0 is a self-administered questionnaire that assesses the global beneficial effects of therapy at three different levels (study joint, disease, person) and grades adverse effects of therapy, using a battery of 8 questions.

OGI^™ 8.0 uses Likert-type scaling, and has been used in whole or in part in two Canadian studies.
