Samenvatting

Aim:
To explore which factors, influencing dietary behaviour change support among patients by Dutch community nurses (CNs; nurses), are key focal points in training programmes.

Background:
Nurses have an important role in counselling patients towards healthier dietary behaviour to prevent or delay long-term complications from chronic lifestyle-related diseases. Most nurses do not incorporate dietary behaviour change support in their routines to the fullest potential.

Design:
A qualitative descriptive study.

Methods:
Data were collected in the Netherlands in 2018–2019 via semi-structured face-to-face interviews with 18 nurses. Interview guide themes were informed by the COM-B model, using validated descriptions in Dutch. Data were recorded, transcribed and analysed using inductive thematic analysis.

Results:
Factors that affected dietary behaviour change support were linked to (1) the nurse (role identity, dietary knowledge and competences such as methodical approach, behaviour change techniques and communication techniques), (2) nurse–patient encounter (building a relationship with a patient, supporting patient autonomy and tailoring the approach) and (3) cooperation and organizational context.

Conclusion:
It is of utmost importance to pay attention to nurses' role identity regarding dietary behaviour change support, as this underlies professional behaviour. This should be accompanied by improving competences on dietary behaviour change support. Focus on competences regarding the application of behaviour change technique is crucial. Furthermore, having a relationship of trust with a patient was important for discussing sensitive topics such as diet.

Impact:
The promotion of a healthy diet provides opportunities to contribute to patient autonomy and self-management. Well-fitted training offers for (senior) nurses will lead to improved professional practice of nurses, leading to healthier dietary behaviour of patients.
