Forensic mental health care is faced with serious problems in the recruitment and retention of newly graduated nurses (NGNs). Research into NGNs' experiences of their transition to and evaluations of transition programs in forensic care is sparse, and more studies are called for. This study aimed to investigate the characteristics of NGNs' experiences and perceptions of their transition into a forensic setting and their evaluations of the introduction period. Three focus group interviews were carried out, involving 13 NGNs, lasting 79.68 minutes on average. They were analyzed using thematic analysis. Results show two main themes: “feeling safe” and “taking on responsibilities.” If NGNs felt overburdened with clinical responsibilities during their transition, their feeling of safety reduced. The converse also applied; theThe safer they felt, the greater clinical responsibility they felt capable of handling. The more difficult the NGNs perceived the informal transition, the more unsafe they felt, and the more negatively they perceived the responsibilities placed upon them. Tailored programs designed to support both the informal and formal transitions are recommended, along with preceptorship, theoretical training, and role-based support, such as a shift manager, along with early introduction to conflict management and security measures.
