Crisis situations are frequent among people with mental health disorders. Several interventions have been developed to act in prevention, including crisis plans recognized as particularly effective in reducing coercive measures. In the literature, several models of crisis plans are proposed with similar aims and contents. Based on the methodology proposed by the Joanna Briggs Institute, a scoping review was conducted to map the state of knowledge on crisis plans in adult mental health settings. The literature search conducted on six databases (CINAHL, PubMed, Medline, EMBASE, PsychINFO and Cochrane) yielded 2435 articles. Of these, 122 full‐text articles were assessed for eligibility, and 78 met the inclusion criteria. Studies were critically appraised using the Joanna Briggs Institute appraisal tools, and data were extracted by two independent reviewers. Content analysis identified a typology of crisis plans: (1) the legal crisis plan and (2) the formal crisis plan. Five modalities were identified for its completion: the sections, the moment, the completion steps, the people involved and the training of key actors. Most identified outcomes are consistent with the main purpose of the intervention, which is crisis prevention. However, the most identified outcomes focused on the service user's recovery and indicated that crisis plans could provide an opportunity to operationalize recovery in mental healthcare, thus suggesting an evolution in the aim of the intervention. Future research should further focus on the modalities of crisis plans to guide the implementation in clinical practice.
