  • Active involvement of children aged 11–12 years in the development of a healthy nutrition intervention – a qualitative evaluation from researchers’ and children’s perspectives

    Open Access•Hannah Jilani, Imke Schilling et al.•ARTICLE•BMC Public Health•2025

    The evaluation of children's active involvement highlighted the importance of clear expectation management for successful collaboration. This requires time, openness, and flexibility from all participants. The findings provide practical insights for researchers, supporting the effective involvement of children while reducing potential barriers in future projects

  • Social health markers in the context of cognitive decline and dementia

    Open Access•Martina Sinta Kristanti, Myrra Vernooij-Dassen et al.•ARTICLE•Frontiers in Psychiatry•2024

    The current study identified both well-known and novel social health markers in the context of dementia, mapped to the social health framework we developed. Future research should focus on translating these markers into validated measures and on developing social health focused interventions for persons with dementia

  • Making sense of complexity in context and implementation

    Open Access•Lisa M Pfadenhauer, Ansgar Gerhardus et al.•ARTICLE•Implementation Science•2017

    BACKGROUND: The effectiveness of complex interventions, as well as their success in reaching relevant populations, is critically influenced by their implementation in a given context. Current conceptual frameworks often fail to address context and implementation in an integrated way and, where addressed, they tend to focus on organisational context and are mostly concerned with specific health fields. Our objective was to develop a framework to f…

  • A descriptive review on methods to prioritize outcomes in a health care context

    Open Access•I Janssen, Inger M Janssen et al.•ARTICLE•Health Expectations•2015

  • A long story made too short

    Ansgar Gerhardus, Oliver Razum•ARTICLE•Journal of Epidemiology and…•2010•Cited by: 1•References: 7

    The story of epidemiologists and surrogate variables is one of a classic love–hate relationship. Epidemiologists love surrogates because many studies would not be possible without them. When events are rare or the time between an intervention and the outcome is long, surrogate variables are used to fill the gap. Epidemiologists hate surrogate variables because they introduce an additional step in the chain between intervention (or exposure) and o…
