What Exactly Is "Complicated" Grief? A Scoping Research Literature Review to Understand Its Risk Factors and Prevalence.

Most people will experience bereavement grief, but some suffer from persistent or prolonged (PoP) grief, grief that used to be identified as "complicated" before recent DSM-5 and ICD-11 definitional developments. In 2020, a scoping literature review was undertaken to identify and consolidate contemporary evidence from research articles published in 2018 or 2019 in paper-based and open access peer-review journals on: (a) the incidence or prevalence of PoP grief, and (b) who develops it or is diagnosed as suffering from it, and correspondingly what causative factors or predictors are associated with PoP grief. All of the 11 identified research articles reported an incidence or prevalence rate, with these varying greatly, but with a much higher rate now that a 6-month post-death measurement timeframe is used. The predictors or factors among people who were identified as having PoP grief also varied considerably, although sudden and unexpected deaths were often implicated.

A Scoping Research Literature Review to Identify Contemporary Evidence on the Incidence, Causes, and Impacts of End-of-Life Intra-Family Conflict.

When someone is terminally ill, it is often a very stressful time for the dying person and their family. It would not be unusual for intra-family conflict, involving one or more family members and even the dying person, to occur. However, this type of conflict has not been identified as an end-of-life issue needing to be noticed and addressed or prevented when possible. This lack of attention could be because it is not known how common or how impactful this type of conflict is. A scoping research literature review was conducted for available 2004-2019 evidence on the incidence or prevalence of intra-family conflict, factors contributing to it or causing it, and the outcomes or impact of it. A search for published peer-review articles identified 18 research reports for a scoping review. The 18 studies, all conducted in developed countries, revealed intra-family conflict is often present; and with a range of harmful effects for the dying person, the family as a whole or individual family members, and other persons and organizations. The identified factors contributing to or predisposing intra-family conflict were grouped into three categories: (a) family disagreements over curative treatment and/or end-of-life care and decisions, (b) previous family conflict and other family dynamic matters, and (c) the dying process itself. The evidence identified through this scoping review, although relatively minimal, should be useful for planning future research and for raising awareness of end-of-life intra-family conflict to improve social services and palliative programs or services.
