New products have emerged to meet this need, including nasal glucagon (NG) and auto-injector glucagon (AI). This study evaluated the psychometric properties of a new measure, the Glucagon Device Attitudes Questionnaire (GDAQ), in assessing attitudes toward NG and AI from the perspectives of persons with diabetes on insulin (PWDs), caregivers, and acquaintances.Methods: Developed based on qualitative research, the GDAQ consists of 38 rating items for each device and 16 direct-elicitation of attitudes of device relative to each other. It was administered to participants via a cross-sectional online survey. Twenty-six rating items were included in principal component analysis and confirmatory factor analysis. Items comprising each factor were averaged to form scales. Additionally, 12 direct elicitation items were averaged to form an overall âAttitudesâ scale. Reliability and validity analyses were conducted. Descriptive statistics were provided for the rating items not included in the factor analysis.Results: A total of 405 PWDs, 313 caregivers, and 305 acquaintances participated. Three factors were identified: âPrepared and Protectedâ (7 items), âHesitationâ (12 items), and âDevice Perceptions by Othersâ (7 items); factor loadings ranged from 0.13 to 0.92, 0.50 to 0.89, and 0.16 to 0.92, respectively. Cronbachâs alpha for the four scales ranged from 0.76 to 0.96. Correlations of the scales with their global item ranged from 0.30 to 0.90. The items outside of the factor analysis showed good distribution in responses and differentiation between the two devices.Discussion: This study supports the validity and reliability of the GDAQ, which successfully conceptualizes attitudes towards devices for administering glucagon among different respondent groups. Use of the GDAQ can help guide the development and testing of new glucagon drug/device combinations.Keywords: diabetes, severe hypoglycemic events, glucagon delivery device, patient attitudes
