Background: Children show long-term psychological distress if family communication and illness-related information are poor during and after a parent's illness and death. Few psychosocial interventions for families with minor children living with a parent who has a life-threatening illness have been evaluated rigorously. Even fewer interventions have been family-centered. One exception is the Family Talk Intervention (FTI), which has shown promising results regarding increased illness-related knowledge and improved family communication. However, FTI has not yet been evaluated in palliative care. This study therefore aimed to explore the potential effects of FTI from the perspectives of minor children whose parent is cared for in specialized palliative home care. Methods: This pilot intervention study involves questionnaire and interview data collected from children after participation in FTI. Families were recruited from two specialized palliative home care units. To be included, families must include one parent with life-threatening illness, at least one child aged 6-19 years, and understand and speak Swedish. Twenty families with a total of 34 children participated in FTI; 23 children answered the questionnaire, and 22 were interviewed after participation. Results: The children reported that FTI increased their knowledge about their parents' illness. They said the interventionist helped them to handle school-related problems, establish professional counselling, and find strength to maintain everyday life. Children aged 8-12 reported that talking with their parents became easier after FTI, whereas communication was unchanged for teenagers and between siblings. Children also reported having been helped to prepare for the future, and that they benefitted from advice about how to maintain everyday life and minimize conflicts within the family. Conclusions: Children who participated in FTI reported that it was helpful in many ways, providing illness-related information and improving family communication when a parent has a life-threatening illness. Other potential positive effects reported by the children were that FTI facilitated their preparation for the future, decreased family conflicts, and started to build up resilience.
