Sustaining evidence-based interventions under real-world conditions: results from a large-scale diffusion project

Area of Science:

• Public Health
• Criminology
• Program Implementation Science

Background:

• Evidence-based interventions (EBIs) require sustained implementation for maximum public health impact.
• Funding cycles often pose a challenge to the long-term operational viability of EBIs.
• The Pennsylvania Commission on Crime and Delinquency's initiative provides a relevant case study for examining EBI sustainability.

Purpose of the Study:

• To identify factors predicting the sustainability of EBIs post-funding.
• To determine correlates of actual post-funding sustainability.
• To assess the long-term operational status of interventions from a specific state initiative.

Main Methods:

• Cross-sectional study design examining factors associated with predicted and actual sustainability.
• Analysis of data from the Pennsylvania Commission on Crime and Delinquency's Research-Based Delinquency and Violence Prevention Initiative.
• Assessment of intervention status five years post-funding.

Main Results:

• Predicted sustainability correlated with program staff, school support, and administrator backing.
• Predicted sustainability strongly predicted actual sustainability.
• Actual sustainability linked to financial planning and alignment with agency/school goals.
• Five years post-funding, 45% of interventions operated at the same or higher level, 22% at a reduced level, and 33% ceased operation.

Conclusions:

• Sustaining EBIs requires proactive financial planning and strategic alignment with organizational goals.
• Strong program staff and institutional support are crucial for initial sustainability predictions and actual outcomes.
• Future research should focus on actionable strategies to enhance the long-term viability of public health and delinquency prevention programs.
