However, there seems to be a lack of clarity in this notion, both conceptually and practically. In low and middle-income countries, programs to support the diffusion of new technological tools are multiplying. They face challenges and difficulties that need to be understood with an in-depth analysis of the acceptability of these innovations. We performed a scoping review to explore the theories, methods and conceptual frameworks that have been used to measure and understand the acceptability of technological health innovations in sub-Saharan Africa. The review confirmed the lack of common definitions, conceptualizations and practical tools addressing the acceptability of health innovations. To synthesize and combine evidence, both theoretically and empirically, we then used the "best fit framework synthesis" method. Based on five conceptual and theoretical frameworks from scientific literature and evidence from 33 empirical studies, we built a conceptual framework in order to understand the acceptability of technological health innovations. This framework comprises 6 determinants (compatibility, social influence, personal emotions, perceived disadvantages, perceived advantages and perceived complexity) and two moderating factors (intervention and context). This knowledge synthesis work has also enabled us to propose a chronology of the different stages of acceptability. specialized Acceptability Innovation Health Scoping review Best fit framework synthesis Sub-Saharan Africa AFRIQUE SUBSAHARIENNE 056 23 1 930 [15 ] 2023 https://www.documentation.ird.fr/hor/fdi:010090189 10.1186/s12913-023-09897-4 [F B010090189] https://www.documentation.ird.fr/hor/fdi:010090189 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-10/010090189.pdf IRD - Base Horizon / Pleins textes 2023-10-06 2025-02-24 fdi:010090189 fre
