ABSTRACT Objective The aim of this study is to (1) identify similarities and differences in psychosocial burdens and support needs experienced by parent, partner and adult‐child caregivers and (2) identify support needs of family caregivers regarding peer support programs. Methods Semi‐structured interviews ( n = 30) were conducted with family caregivers of cancer patients. Interviews were transcribed and analyzed by inductive content analysis to identify themes. Results Ten categories of burden were identified for all three groups of caregivers. Partners emphasized the time burden through caregiving, parents and adult‐child caregivers accentuated the emotional burden. All caregivers wished for peer‐to‐peer exchange which will provide the feeling not to be alone, to share emotions and to prepare for what will come next. Preferences for matching with peers with similar prognosis for their sick relative and similar living conditions were found. Conclusions Partner, parent and adult‐child caregivers describe similar burdens of caregiving. They wish for peer support programs that allow them to share their experiences with persons who understand their situation. Therefore, caregivers desire a good match with peers to enhance the positive outcome of peer exchange.
