AB  - WHO has defined intrinsic capacity (IC) as the composite of all physical and 
      mental capacities of an individual covering five subdomains: cognition, 
      locomotion, sensory, vitality, and psychological. Despite this well accepted 
      definition, the conceptual and measurement model of IC remains unclear, which 
      hampers a standardized operationalization of the construct. We performed a 
      scoping review to give a comprehensive overview of the extent to which the 
      current literature of IC addresses and assumes the conceptual framework and 
      measurement model of IC as reflective or formative. For inclusion, we considered 
      all types of articles that were published in peer-reviewed journals except for 
      protocol articles. A systematic search of 6 databases from different disciplines 
      led to the inclusion of 31 papers. We found inconsistency and gaps in the 
      descriptions of IC. Most of the papers did not define the measurement model. In 
      the conceptual background and validation articles, we identified descriptions of 
      both reflective and formative measurement models while in empirical studies 
      applying IC measurements the underlying assumptions remained mainly unclear. 
      Defining a measurement model is not merely a theoretical matter but influences 
      the operationalization and validation processes of the construct. This study 
      raised questions about the most fundamental features of the IC construct and 
      discusses whether IC should be considered as an underlying latent trait of all 
      capacities (reflective construct) or an aggregate summary measure of the 
      subdomain capacities (formative construct).
