IntroductionThe global burden of cancer is escalating, with Asia accounting for over half of cancer-related deaths worldwide. As cancer often diminishes patients’ quality of life and sense of dignity, dignity-related interventions have gained prominence in palliative care for patients with cancer. However, a more in-depth exploration of the involvement of families, as the fundamental social units in Confucian Asian cultures, and cultural considerations is currently lacking. This scoping review focuses specifically on patients with cancer receiving palliative care and aims to offer a comprehensive synthesis of the existing evidence on family participatory dignity interventions, addressing the need for a holistic understanding of this emerging field to guide future research and clinical practice.Methods and analysisThis scoping review will be meticulously structured according to the five-stage framework established by Arksey and O’Malley, complemented by the scoping review methodology of the Joanna Briggs Institute. Our search will encompass a comprehensive array of databases, including PubMed, Embase, The Cochrane Library, CINAHL, Web of Science, PsycINFO, Scopus, CNKI and Wanfang Data, from their inception up to August 2024, targeting both English and Chinese relevant literature. To ensure a thorough exploration, we will also delve into grey literature via OpenGrey, Google Scholar and citation chaining. This scoping review will include all types of quantitative or mixed methods designs and qualitative studies. We will extract data on study design, sample size, intervention details, outcome measures and any other relevant information. The screening process will be conducted by two independent reviewers, who will meticulously assess the titles and abstracts, followed by a full-text review to select relevant studies. Discrepancies will be resolved through consensus discussions with a third reviewer. Data extraction will be executed using a standardised tool, and the findings will be systematically presented in tabular form with an accompanying narrative to summarise all relevant interventions, their characteristics, outcomes and key findings.Ethics and disseminationEthical approval for this scoping review is not required, since the methodology merely involves the collection and review of publicly available literature. Our findings will not only be presented and discussed in a peer-reviewed article but also shared at conferences relevant to the topic.Trial registrationOur scoping review protocol has been formally registered with the Open Science Framework.
