The Hypoglycaemia Awareness Questionnaire is a profile measure of hypoglycaemia awareness (when awake/asleep) and hypoglycaemia frequency, severity and impact (healthcare utilisation).
It has robust face and content validity; satisfactory structure and internal reliability; good convergent, divergent and known groups validity. The ‘impaired awareness’ sub-scale and other items contribute significantly to models explaining recall of severe and nocturnal hypoglycaemia. It has proven responsiveness in clinical trials.
The 5-item ‘impaired awareness’ sub-scale has been translated and linguistically validated in 20 languages. We approve rigorous industry-standard procedures. All new translations need to be authorised by, and remain the copyright of, AHP Research.
