Developing and validating a novel staff questionnaire to identify barriers and enablers to nutrition and mealtime care on hospital wards

Abstract

Aims: Improving hospital nutrition and mealtime care is complex and often requires multifaceted interventions and implementation strategies to change how staff, wards and systems operate. This study aimed to develop and validate a staff questionnaire to identify multilevel barriers and enablers to optimal nutrition and mealtime care on hospital wards, to inform and evaluate local quality improvement. Methods: Literature review, multidisciplinary focus groups and end-user testing informed questionnaire development and establishment of content and face validity. To determine the construct validity, the questionnaire was administered to ward staff working in five wards across two facilities (acute hospital, rehabilitation unit). Exploratory factor analysis was used to estimate the number of factors and to guide decisions about whether to retain or reject individual items. Scale reliability was assessed using Cronbach's alpha. Results: The questionnaire was completed by 138 staff, with most respondents being nurses (57%) and working in the acute care facility (76%). Exploratory factor analysis supported construct validity of four of the original seven subscales. The final questionnaire consisted of 17 items and 4 sub sub-scales related to (1) Personal Staff Role; (2) Food Service; (3) Organisational Support, and (4) Family Involvement; each sub-scale demonstrated good reliability with Cronbach's alpha values all >0.70. Conclusion: This novel and brief questionnaire shows good reliability and preliminary evidence of construct validity in this small sample. It provides a potentially useful instrument to identify barriers and enablers to nutrition and mealtime care from the staff perspective and inform where improvement efforts should be focused.
