Research on experiences of transition into mental health-care roles seems sparse, but it is vital in order to produce a comprehensive understanding of the transition into mental health-care roles and to serve as a foundation for future research and development. The aim of the present study was to review existing research literature, and in doing so, investigate transition programmes for new graduate nurses (NGN) into mental health care, and their experiences of role transition and evaluations of participation in transition programmes. The literature review spans literature published after the year 2000. The literature search was conducted using the following databases: CINAHL, Psychology and Behavioral Sciences Collection, PsycINFO, and Pubmed. Search results consisting of 14 articles were analysed using thematic analysis. Results from the analysis showed four overall themes: nursing education, transition programmes and evaluations, working environment, and the NGN role. We conclude that it is not possible to produce a comprehensive understanding specifically concerning the transition programmes for NGN into mental health care, and that further research is necessary due to the limitations of this review.
