Experiences in the application of logic models in the context of workplace health promotion - A focus group discussion.

Gathering evidence on complex workplace health promotion interventions faces methodological challenges. Therefore, the application of logic models as a theory of change is recommended to support outcome and process evaluations. The present study explores challenges and opportunities of applying logic models in application-oriented intervention research on workplace health promotion. A focus group (n = 6), consisting of scientists and workplace health promotion practitioners, was conducted using a semi-structured interview guide. The recorded qualitative data were transcribed and analysed using the structuring content analysis method. According to the focus group, logic models provide several opportunities for planning and evaluating complex workplace health promotion interventions. Logic models support the communication between science and practice, and have benefits for the provider of workplace health promotion interventions. The main challenges in working with logic models were dealing with the complex and constantly developing intervention and with the derivation and implementation of reasonable evaluation methods. The focus group exposed repeated application and a shared understanding between stakeholders as facilitators for working with logic models. In conclusion, at the science-practice interface, logic models could enhance the integrative understanding and the further development of evidence-based workplace health promotion.
