An increasing body of evidence suggests that transitioning from school to adult life can be challenging for young people with intellectual disability. Transition from secondary school includes preparation of students before leaving the school environment and may continue several years into adult life. Transition challenges may include isolation, mental health problems, and reduced participation in employment and tertiary education. Some literature indicate links between poor post-school outcomes, and ineffective collaboration between school systems, disability services, and employers. Yet, consolidated evidence to understand how young people themselves experience transition from school is needed. The aim of this scoping review is to draw together current literature reporting what young people with intellectual disability say about transitioning to life after school. Methods: Using the Joanna Briggs scoping review methodology and the population, concept, context (PCC) framework, a systematic strategy will identify peer-reviewed qualitative research and grey literature reporting the voices of young people with intellectual disability to better understand personal experiences of transition to life after school. The PCC framework outlined in this section directed the research question and the development of the search strategy for this study. Population The population in this review will be young people with intellectual disability aged 15-30 years to capture a broad transition period. This age range reflects the varied definitions of what constitutes a young person. Increasing evidence also indicates that the transition to adulthood often extends well into the 20s or even later (1, 22), particularly for people with intellectual disability (23). There is no universally accepted definition of intellectual disability, and language use changes over time and in different contexts. Therefore, for the purposes of this scoping review a broad approach to searching will be taken, utilising a range of current and older terms including disability or disabled or handicap; intellectual, learning, and developmental; cognitive impairment; and mental retardation to include US literature prior to 2013. The term ‘mental retardation’ is now considered derogatory in most English speaking countries, and was officially removed from the DSM-5 and ICD-11 in 2007, but was retained in some publications for several years. The use of the term also persisted in US federal policies until 2010, when President Obama signed the legislation required to replace the term with intellectual disability (24). The final rule was adopted in January 2013 (25). Concept The concept or phenomenon of interest to be explored in this scoping review is the experiences of young people with intellectual disability transitioning to life after school. This phenomenon incorporates three key phases for which varying terminology is used within the literature before, during and after transitioning. In the context of this scoping review, the search strategy will include terms that relate to: a) planning for the end of secondary education, which should take place several years in advance, b) the time of leaving high school and moving and settling into what comes next, for example, c) living independently, community participation, education and training, and/or employment. Therefore research and grey literature about any post-school setting will be considered, including on post-secondary education, disability services, and the wider community. However, if used as a main search string, these terms may narrow the results significantly, so it is likely the settings will be considered in the extraction phase to help organise the review and analysis. Context Literature reporting young people’s own experiences and views on the transition to adulthood will be prioritised to better understand what they consider important about their transition from school. Young people have a moral and ethical right to be involved in decisions that impact their lives, in line with the UN Convention of Rights of the Child (UNCRC) (26) and UN Convention of Rights of Persons with Disability (UNCRPD) (27). The searches will be for qualitative research involving young people with intellectual disability as participants, and grey literature that focuses on what is important to young people. Qualitative study designs including, but not limited to, phenomenological, grounded theory, ethnographic, action research and narrative inquiry will be considered. Papers that include a range of perspectives will be included so long as the views or experiences of young people themselves can be clearly distinguished in the findings. Where voices of parents, educators, service providers have been included, the reviewers will prioritise the perspectives of young people. The review will explore scope and foci of topics, identify gaps in current evidence, and highlight approaches and methods used by investigators to include young peoples’ voices. Database searches for relevant qualitative research will include ERIC via Proquest, Ovid MEDLINE, selected EbscoHost databases, and Web of Science. Non-indexed and grey literature such as policies and reports will be searched via TROVE, ProQuest Dissertations & Theses, and Google (with URL control and by crawling key agency websites). Studies will be selected using a three-step process: i) managing search results and removing duplicates, ii) title and abstract screening by two independent reviewers, and iii) full text review of included articles against inclusion criteria by two independent reviewers. Data will be tabulated and presented in a narrative summary, aligning with the objectives and scope of this review. Discussion: Review findings will inform policy makers, educators and disability support organisations of transition challenges experienced by young people with intellectual disability. The findings will enable the design and implementation of more accessible and holistic transition to address barriers in the process, ensuring future guidelines reflect the voices of those they intend to support.
