Applying the Non-adoption, Abandonment, Scale-up, Spread and Sustainability (NASSS) Framework to evaluate automated evidence synthesis in health behaviour change

NASSS is a framework for understanding the non-adoption, abandonment, scale-up, spread and sustainability of technology within a complex healthcare system composed of many interacting entities. This brief review explores the potential of NASSS for evaluating automated evidence synthesis in health behaviour change by applying it to the ongoing Human Behaviour-Change Project, which aims to revolutionise evidence synthesis within behaviour change intervention research. To increase the relevance of NASSS for health behaviour change, we recommend i) terminology changes (‘condition’ to ‘behaviour’ and ‘patient’ to ‘end user’) and ii) that NASSS is used prospectively to iteratively address complexities. We draw conclusions about i) the need to specify the organisations that will use the technology, ii) identifying what to do if interdependencies fail and iii) NASSS arguably being beneficial for technology developments in health behaviour change more generally, particularly for intervention development.
