RESUMO
Mental health literacy (MHL) has been identified as a factor influencing early help-seeking for mental health problems (MHPs) and stigmatizing attitudes. However, the lack of consensus on its definition has led to considerable heterogeneity in measurement and, consequently, methodological challenges in comparing data. In this way, the present study was conducted with the following objectives: in Phase I, mapping the existing literature through a scoping review; in Phase 2, 28 experts in the field of mental health participated to develop a consensus statement on the relevance and importance of the findings from Phase 1. A total of 37 articles were included for review. Notable nuances were identified in the conceptualization of MHL, particularly with regard to the fact that it should not be limited to mental disorders but should also encompass mental health. Furthermore, the sociocultural influence was highlighted as shaping MHL, recognizing it as a modifiable competence that adapts to different contexts and life stages, involving both individual and collective levels. The experts deemed the findings pertinent and relevant with a high degree of consensus, except for factors related to MHL. This framework provides a refined definition of MHL and related factors that should be taken into account to guide nursing and other disciplines' studies and interventions on MHL. The evolution of this concept includes dimensions to be considered in future research, especially when developing new measurement instruments or implementing educational programmes. This knowledge and skills cannot be determined globally without considering the context and development of the individual.
