Abstract
BACKGROUND: People with acquired brain injuries (ABIs) often experience residual limitations and co-morbid mental illnesses that restrict work participation. Employers are key in enabling successful return-to-work and job retention. OBJECTIVE: This review aimed to explore employers' perspectives of factors influencing their support for people with ABIs and/or mental illness to return to- and stay in work. Review questions focused on barriers and facilitators to their support, and contextual characteristics present at the time. METHODS: Five databases were searched from October 2010 until November 2023 for relevant qualitative studies published in English. Findings from included studies (N = 25) were synthesised using thematic synthesis. RESULTS: Included studies focused on employees with ABI or mental illness, rather than dually diagnosed ABI and mental illness. Employers' support was influenced by their awareness/knowledge of- and attitudes towards the employee's condition/illness; their skills and experience in supportive strategies; factors related to provision of work accommodations; and stakeholder influence. Similarities and differences in influential factors were observed across the ABI and mental illness literature. Contextual characteristics related to organisational characteristics, cultural taboo, and involvement of certain stakeholders. CONCLUSIONS: ABI survivors (with and without co-morbid mental illness) and their employers may benefit from specialist support and resources to guide them through the return-to-work process. Further research is needed to investigate employers' knowledge of ABI and mental illness and supportive strategies. Exploration of the influence of other stakeholders, socio-demographic characteristics, and contextual factors on employers' return-to-work and retention support for ABI survivors with co-morbid mental illness is warranted.
