RESUMO
Introduction@#Hazards of hypoglycemia include accidents, cardiovascular events, neurologic damage, and impaired hypoglycemia awareness (IHA) which presents as inability to perceive and respond to hypoglycemic warning symptoms.@*Objective@#This study aimed to develop the first questionnaire evaluating IHA adapted from Clarke Hypoglycemia Index (CHI) and validated among adult Filipino patients with Type 2 Diabetes Mellitus (T2DM). @*Methodology@#A questionnaire development study was conducted involving CHI linguistic translation, its modification through literature review and focus group discussions, panel synthesis, and content validity. A cross-sectional analytic study followed by administration of the questionnaire to 117 adult Filipinos with T2DM, advanced age, long-standing T2DM, insulin or sulfonylurea, polypharmacy, comorbidities and/or prior hypoglycemia. There were 9 participants in pilot testing, 69 in criterion validity against continuous glucose monitoring (CGM), and 108 in construct validity. @*Results@#IHA domains in the concept map included Elusive Euglycemia Model, Developmental Model, and Cognitive Model. The Filipino-CHI formulated had 8 questions with content validity scores ranging from 87.5-93.75%. Owing to brevity, its internal consistency Cronbach’s alpha was 0.45. Criterion validity against CGM yielded 21 patients with biochemical hypoglycemic events, of which 2 had clinical hypoglycemic events and 19 were positive monitor-identified IHA. A questionnaire IHA cutoff score of ≥4 had sensitivity of 89.47%, and area under the curve of 0.55. @*Conclusion@#An 8-item questionnaire evaluating IHA among adult Filipino T2DM patients was developed and validated.
