RESUMEN
Within the last decade, stakeholder engagement in research has become increasingly popular in childhood disability research; however, literature on the engagement of youth with neurodisabilities and their families in evidence syntheses is underdeveloped. Involving patients as partners in research has the potential to improve applicability and relevance of the research and benefit patient partners (e.g. enhanced self-esteem, increased research knowledge and skills); however, the methods, challenges, outcomes and recommendations of engaging youth with neurodisabilities and their families in evidence syntheses are unknown. Two parents of youth with complex disability needs were engaged as partners throughout this review. Following methods outlined by Arksey and O'Malley (2005), the primary research question in this scoping review is twofold: (i) what activities have youth with neurodisabilities and their families been engaged in as part of evidence syntheses and (ii) what were the outcomes of that engagement? After full text review of 369 articles, nine articles were included. Youth and families were engaged prior to the evidence synthesis and at every stage in the project, most often during data analysis where they contextualized the findings. Youth and family engagement were not formally evaluated; however, positive outcomes were reported by parents and researchers. Challenges such as increased time, sustaining engagement, and parents' dissatisfaction with their level of involvement were reported. Recommendations centred around providing partners with information, building relationships via social media, and openly communicating about roles, feedback and logistics. Childhood disability researchers should be aware of how they can increase engagement opportunities at all stages of evidence syntheses and how they might improve accessibility for youth with neurodisabilities and their families. Further research is needed to solidify a unified framework for conduct and reporting of youth and family engagement in evidence syntheses.
