What we hope for has a large impact on how we feel and behave. Research on the determinants and effects of a hopeful disposition is increasing in several academic fields, such as psychology, nursing and organizational studies. However, how hope is defined differs significantly between disciplines, leading to fragmentation in the insights that we can draw from this research. This systematic review aims to provide an extensive overview of the ascribed characteristics of the concept of hope in ten different academic fields. Using phenomenographic research methods, these characterizations are collected and categorized to offer a comprehensive conceptual framework of hope. The resulting framework comprises 7 themes and 41 sub-themes. We show how this framework can be used to obtain a fuller understanding of the concept of hope and of possible blind spots within specific research fields.
