Should We Scale-Up? A Mixed Methods Process Evaluation of an Intervention Targeting Sedentary Office Workers Using...

Area of Science:

• Occupational Health
• Behavioral Science
• Public Health Interventions

Background:

• Sedentary behavior interventions in office settings require effective scale-up strategies for broader impact.
• The RE-AIM QuEST framework was employed to assess the scalability of a workplace intervention designed to reduce and interrupt sitting time.

Purpose of the Study:

• To evaluate the implementation and scale-up potential of a consultation-based workplace intervention targeting sedentary behavior.
• To identify barriers and facilitators influencing the scalability of workplace health promotion initiatives.

Main Methods:

• Utilized the RE-AIM QuEST framework to assess intervention scalability.
• Collected data from intervention participants, non-participants, and key informants via interviews, focus groups, and questionnaires.
• Employed descriptive statistics for questionnaires and thematic analysis for qualitative data.

Main Results:

• Key barriers to scale-up included participant burden (activity monitoring), limited management support, policy influence, scheduling/location flexibility issues, and cost.
• Facilitators for scale-up comprised visible leadership, positive workplace social/cultural changes, high intervention acceptability, and integration with existing wellbeing programs.

Conclusions:

• The intervention demonstrates potential for scale-up, but requires modifications to address identified barriers.
• Future research on sedentary behavior interventions should prioritize scalability assessment during pilot phases.
