Abstract
BACKGROUND: Hybrid work models are increasingly common, but evidence-based strategies for health promotion for working from home are still rare. The aim of this study is to implement a complex digital intervention tailored to the specific needs of managers and employees of different companies and to evaluate its feasibility, acceptance and health impact. METHODS: An intervention with three modules addressing the topics 1) remote leadership, 2) efficient work from home and 3) ergonomics and active breaks is implemented and evaluated in five medium-sized companies using an exploratory cluster-randomized controlled design. The individual modules include different components (i.e., workshops, a workbook, counseling sessions, active breaks, information videos). The intervention group (IG) receives the intervention from Feb-Apr 2025; the waitlisted intervention control group (WG) from Jun-Aug 2025. In the process evaluation, eight implementation outcomes are assessed (e.g., adoption, reach, penetration). Health-related effects are measured via the 8-item Short-Form Health Survey. Data will be collected at three time points: Jan (T1), May (T2), and Sept 2025 (T3). RESULTS: In the IG, the average cluster (i.e. department or company) size was 123 potential participants. Adoption: 105 of 308 employees of the IG registered for the intervention (93 for module 2 and 12 for module 3) with full participation. Penetration ranged from 10 % to 54 %. Reach: The intervention engaged employees working from home on average on two days per week at T1 (31.4 %) with high satisfaction regarding their work (72.5 %) and home office setup (62.8 %). At the conference, further implementation outcomes and health-related effects will be presented. DISCUSSION AND CONCLUSIONS: Preliminary results of the process evaluation point to a high acceptance and penetration of the intervention within the companies, highlighting the intervention's practical relevance and overall suitability. KEY MESSAGES: • The complex intervention demonstrated good feasibility and high acceptance among hybrid workers. • Preliminary process evaluation suggests promising reach and penetration across diverse organizational settings.
