Several studies have highlighted the significant role of families in end-of-life care. Carers' well-being may depend on how they experience the care and support provided to their loved ones. This study was conducted to investigate family caregivers' assessment of specialized end-of-life care in a sample of 119 close family members in Iceland. The response rate was 58.8% (n = 70). Furthermore, the aim was to assess the psychometric characteristics of the Icelandic version of Family Assessment of Treatment at the End of Life (FATE).
