Contribution Analysis of a Complex System During Disruptions

Abstract

The U.S. National Institute of Occupational Safety and Health (NIOSH) supports 11 regional centers to conduct research and outreach in agriculture, fishing, and forestry. The Southwest Center for Agricultural Health, Injury Prevention, and Education serves Arkansas, Louisiana, New Mexico, Oklahoma, and Texas. The 2016–2022 evaluation used contribution analysis since it is effective in evaluating complex systems with diverse stakeholders and multiple projects, with partners working toward the same outcome over time. The evaluation responded to the disruptions in program implementation caused by the COVID-19 pandemic and to NIOSH modifications to key elements of contribution analysis procedures.
