Use of volunteers in early years interventions for parents: A scoping review of roles and the extent of evaluation research in this area.

Early years interventions, particularly those supporting parents in the first 1001 days of their infants life, support healthy development of infants and prevent adverse experiences that can have long term negative impacts. Volunteers are often used to deliver such interventions. This scoping review aimed to explore the roles and characteristics of volunteers across early years interventions and map the evaluation in this field to identify gaps in the literature.
