The objective of this scoping review is to identify and map support interventions provided during palliative care to families with dependent children when a parent has a terminal illness. For dependent children, losing a parent through terminal illness can be one of the most traumatic experiences they will face. Without age-appropriate information and support, parental death can lead to unresolved grief, post-traumatic stress, and longer-term negative social, emotional, educational, and behavioral consequences. Support from health care professionals is provided, but challenges within hospice and community palliative care mean the needs of dependent children may not be addressed. Greater emphasis is often placed on children's and families' bereavement needs as opposed to their pre-bereavement needs. The status of pre-bereavement support in palliative care for these families has not been documented. We will include studies of support interventions provided to families with dependent children when a parent has a terminal illness that are delivered during palliative care and in settings including, but not limited to, hospices, hospitals, and the community (including family and care homes). Empirical, peer-reviewed studies based on qualitative, quantitative, or mixed methods data, and gray literature, reporting any stage of intervention development will be included. This review will follow the JBI approach for scoping reviews. Multiple database searches will be conducted. Two authors will independently review full-text articles and extract data. Interventions will be mapped in terms of characteristics, evaluation methods, and implementation challenges. Data will be presented in tables, diagrammatic form, and narrative summary.
