For the last decades, health technology assessment has been strongly promoted in order to provide evidence-based rather than eminence-based healthcare. However, when it comes to implementing interventions that are based on processes and behavior rather than products, importing evidence-based interventions is likely to fail because it ignores the strong influence of contextual factors. In a recently started research project, an alternative approach is tested.

The project aims at improving identification and support of children who have parents with a mental illness in an Austrian region (Tyrol). A theory- and stakeholder-driven approach has been designed in order to co-develop, implement and evaluate practice approaches for improving the situation for children. The former addresses the questions whether, how and why suggested practices may work and the later brings together evidence and practice to develop interventions that are feasible and take the regional context and service settings into account.

Based on evidence from various sources (literature, international and local stakeholder interviews), theories that describe the key mechanisms of action to influence outcomes for children have been developed. A regional and interdisciplinary group of practitioners and people with lived experience has been established to facilitate the development of the theory of change and practice approaches for the region and local service settings. The final practice model is then monitored in the respective organizations with implementation support from the research team.

Theory-driven and co-designed-based approaches are a feasible alternative to ‘off-the-shelf’ evidence-based practices for supporting decision makers in implementing complex interventions. However, they require a broad variety of skills within the research team as well as willingness to accept uncertainties of the final outcomes produced, which can also be of risk to funders. The ongoing project will demonstrate whether the developed practices will be implemented successfully and result in benefits for the affected children.
