The Attitude of Nursing Staff Towards Oral Healthcare for Care-Dependent Older Adults (ANOCO) Questionnaire: Development and Validation

Abstract

Aims: This study aims to report on the development and validation of the Attitude of Nursing staff towards Oral healthcare for Care-dependent Older adults (ANOCO) questionnaire. Methods: The development of the ANOCO questionnaire was performed in three stages between 2008 and 2019. In a first stage, domains related to oral healthcare attitudes were identified. Next, relevant statements per domain were formulated by a Delphi panel in two rounds, resulting in a questionnaire with 32 statements. In a final phase, this questionnaire was subjected to psychometric analysis, including an evaluation of the construct validity, an internal consistency analysis (Cronbachs alpha) and a principal component analysis. Results: The questionnaire could significantly distinguish between known groups (dentists, nurses' aides, nursing students and nurses). Regarding internal consistency, Cronbach's alpha was 0.863 in the first sample (n = 361) and 0.843 in the second sample (n = 1051). Based on principal component analysis, 22 statements were retained. Four components with an eigenvalue of more than 1 explained 45% of the total variance. Conclusion: The ANOCO-22 questionnaire consists of 22 statements and is a valid tool to assess the changes or differences in the attitude of nursing staff towards oral healthcare for care-dependent older adults.
