This study explored the relational dimensions of perinatal grieving. Three perinatally bereaved couples each participated in one interview, as well as a follow-up member check interview. The research question for this study was, “how do bereaved parents grieve jointly following perinatal loss?” Data were collected using the qualitative action-project method, and participants were asked how they grieved together for their deceased baby. Joint grieving processes were identified at couples’ initial interviews, and then, following preliminary analyses, were presented back to the couples during the member check interviews for confirmation and alteration. The data analysis followed the protocols set forth in the action-project and instrumental case study methods, combining all data collected from both sets of interviews. Within-case analyses revealed intentional frameworks for each of the couples joint grieving projects, including: (1) Marveling at God’s presence in the midst of loss and the endurance of grace, respect, and togetherness in marriage, (2) Finding each other in the midst of grieving differences to celebrate and honour the sanctity of life, and (3) Coming back into life to find joy and new responsibilities while continuing to mark and honour the existence of the deceased. Joint grieving involved several commonalities between the couples, including re-learning the uniqueness of one another through grieving, interspersing grief within ongoing faith careers, using the safety of the relationship to express painful thoughts and feelings, oscillations between hope and pain, and the ongoing nature of grieving rituals as joint actions. The findings of this study support the application of broader theoretical models of bereavement to the unique context of perinatal loss, as well as emerging constructivist models of perinatal bereavement. The findings also demonstrate the relevance of relational dimensions of grieving for future empirical and clinical developments in the area of perinatal bereavement.
