Mixed-methods process evaluation of the Dynamic Work study: A multicomponent intervention for office workers to...

Area of Science:

• Occupational Health
• Behavioral Science
• Workplace Interventions

Background:

• Previous studies found no significant reduction in sitting time with the Dynamic Work (DW) intervention.
• Understanding the context, implementation, and mechanisms of impact is crucial for intervention success.

Purpose of the Study:

• To explore the context, implementation, and mechanisms of impact of the DW intervention using mixed-methods data.
• To determine if a higher implementation index score correlates with improved participant outcomes.

Main Methods:

• Mixed-methods approach combining qualitative and quantitative data.
• Analysis of context, recruitment, delivery, and participant experiences.
• Correlation of implementation index scores with changes in sitting time and physical activity.

Main Results:

• High participant satisfaction with the DW intervention was observed.
• Variations in context and implementation delivery across departments were noted.
• Higher implementation scores were associated with reduced overall and occupational sitting time, and increased daily steps, maintained at 8 months for occupational sitting.

Conclusions:

• Intervention implementation is influenced by factors such as component availability, departmental policies, work tasks, and location.
• A higher implementation index score positively impacts key health outcomes for office workers.
• Findings highlight the importance of addressing contextual and implementation factors for effective workplace interventions.
