" A sincere 'how are you ? ' is already a sign of acknowledgement that you ' re there too. "- Interview study on the support needs of adolescents and young adults (AYAs) living with a parent with cancer

Purpose: Parental cancer brings changes and challenges which affect the whole family. Evidence shows heightened psychosocial risk among the offspring. Research among adolescents and young adults (AYAs) facing parental cancer has mainly focused on these psychosocial problems. As a reaction, there has been an increase in research on the needs of this population, since this knowledge is crucial for developing appropriate support. Despite this increase, some AYAs are still underrepresented, namely those over eighteen years old and those who have a parent with incurable cancer. Moreover, the factors hampering or fostering access to and receipt of support addressing their needs are under -investigated. Increasing our understanding of these issues is crucial to developing more effective support interventions for these young people. Our aim was therefore to gain insight into the perceived support needs of AYAs who have a parent with cancer, including the mentioned underrepresented subgroups, and the perceived factors facilitating or hindering their use of support. Methods: We conducted semi -structured interviews with 17 AYAs who have a parent with cancer of any type and stage, which were analyzed using conventional Qualitative Content Analysis (QCA). Results: Six main categories emerged from the data, encompassing various subcategories: 1) Needs surrounding the time of disclosure, 2) Information needs, 3) Informal support needs, 4) Need for effective personal coping strategies, 5) Formal support needs, and 6) Contextual and medical factors affecting support needs. AYAs perceived family members, friends and teachers as important sources of informal support, but lacked contact with peers who also have a parent with cancer. They expressed a need for formal informational and emotional support from their parent ' s medical team, (onco)psychologists, and their general practitioner. AYAs faced barriers in accessing formal support. A proactive attitude from healthcare providers and information about available support would help them meet their needs. Furthermore, we shed new light on needs and issues in postsecondary education. Conclusions: AYAs who are living with their parent with cancer experience informational, emotional, and practical needs in multiple contexts, such as the home, school, leisure and hospital environment. They identify their informal and formal network as important key figures in addressing these needs.
