Evaluating InPACT Intervention-Context Fit in Resource-Limited School Districts in Central Michigan

Area of Science:

• Public Health
• School Health
• Physical Activity Interventions

Background:

• School-based physical activity (PA) interventions often lack contextual assessment, limiting effectiveness and student health outcomes.
• This study evaluated the pre-implementation fit of the Interrupting Prolonged Sitting with ACTivity (InPACT) intervention in a resource-limited school district.

Purpose of the Study:

• To assess the contextual fit of the InPACT classroom PA intervention before implementation.
• To identify and address barriers to intervention fit in a resource-limited setting.

Main Methods:

• The Hexagon Discussion and Analysis Tool was used for assessments by regional school health staff (2020-2021).
• A 5-point Likert scale measured need, fit, support, evidence, usability, and capacity.

Main Results:

• Initial fit score was 19/30, increasing to 28/30 (47% improvement) after one year.
• Increased need for PA due to COVID-19 was noted.
• Improvements in fit, support, capacity, and usability correlated with enhanced coordinator knowledge.

Conclusions:

• Multiple assessments are key to identifying and overcoming intervention fit barriers.
• Addressing contextual factors enhances school readiness for PA interventions, promoting PA equity.
