There is limited research addressing the bereavement needs of parents whose young adult (YA) children have died from cancer. Research within oncology about the impact of child loss has tended to focus on parents of pediatric aged children. We adapted a general bereavement support group curriculum used with adults to address the unique needs of bereaved parents of YAs. Using a quality improvement framework, 25 bereaved parents of YA children participated in one of three 6-session bereavement support group programs during 2020 and 2021. Due to the coronavirus disease 2019 (COVID-19) pandemic, the programs were offered virtually. The participants provided feedback and completed an evaluation. Nineteen mothers and six fathers participated with 20 (80%) completing the evaluation. The median time since the death of their child was 6 months. The participants evaluated the program highly, reporting that they felt less isolated (4.25/5 on a 5-point Likert scale); that their concerns were similar to others (4.45/5); and the discussion topics were relevant (4.20/5). Other topics that were identified included the impact on the family of losing a YA child, and how other relationships change. Forty-five percent of participants expressed a preference for a hybrid delivery model, incorporating in-person and virtual sessions. The majority also wished to continue meeting monthly, given they had little contact with other bereaved parents of YAs. The general bereavement support group curriculum was readily adapted for use with bereaved parents of YA children who died from cancer. A hybrid delivery model was the preferred method for future groups.
