2.1. Conceptual Framework

The evaluation of the implementation phase is based on a logic model that allows for the systematic examination of the relationship between concept planning and impact [33,34]. The core element of the logic model is the assumption of a cause–effect chain. It is based on theoretical assumptions regarding interventions (Assumptions; Theory) and shows with which means and resources (Input) which measures (Activities) are carried out. It also shows, with regard to the measures, how they are used (Output) and what effects are achieved with the target group (Outcome) on the meso–macro level (Impact) [33]. Context factors in terms of personal, environmental, and company-related conditions are also considered to be possible influencing factors. Figure 1 shows the assumptions (see Problems/Assumptions) and planned impact behind the KomRueBer multicomponent intervention. As a project of funding priority Exercise and the Promotion of Physical Activity, the superior aim (Impact) of the KomRueBer study is a contribution to the dissemination of the national recommendations for physical activity and physical activity promotion [4,30]. Thereby, the project focuses on the dissemination in the workplace setting. Furthermore, the logic model shows the inputs, including available resources for the various measures to promote physical activity, the undertaken activities, the outputs comprising the acceptance, usage, and satisfaction of the employees, and lastly, the target outcomes as a result of the multicomponent intervention. The offered activities, respectively measures were developed to be participative in the conception phase [31].

Logic model of KomRueBer study (individual level).

The logic-model-based evaluation focuses on programme activities, outputs, and short-term outcomes for the purpose of physical-activity promotion, physical-activity-related health competence, and knowledge about physical activity. Therefore, a mixed-methods approach comprising quantitative and qualitative methods is applied.
