Three methods are used to identify factors that promote or hinder sustainable healthy eating in nursing homes. Using the Photovoice method, ten citizen scientists capture everyday situations in the form of photos that may support or hinder sustainable healthy eating in nursing homes. These photos are forwarded to the research team for collection and categorization using the low-threshold and widely used tool WhatsApp.
The citizen scientists also conduct interviews with ten residents and employees of the nursing home. A cognitive debriefing is carried out in advance to check the comprehensibility of the semi-structured interview guide. The content is systematically grouped into topics during transcription and weighted according to the frequency with which it is mentioned.
An existing questionnaire on perceptions of sustainable eating habits is being adapted for the nursing home setting in collaboration with the citizen scientists. After a pilot test, it will be forwarded to employees of several long-term care facilities for completion.
