Six-year sustainability of evidence-based intervention implementation quality by community-university partnerships: the PROSPER study

Abstract

There is a knowledge gap concerning how well community-based teams fare in implementing evidence-based interventions (EBIs) over many years, a gap that is important to fill because sustained high quality EBI implementation is essential to public health impact. The current study addresses this gap by evaluating data from PROSPER, a community-university intervention partnership model, in the context of a randomized-control trial of 28 communities. Specifically, it examines community teams' sustainability of implementation quality on a range of measures, for both family-focused and school-based EBIs. Average adherence ratings approached 90% for family-focused and school-based EBIs, across as many as 6 implementation cohorts. Additional indicators of implementation quality similarly showed consistently positive results. Correlations of the implementation quality outcomes with a number of characteristics of community teams and intervention leaders were calculated to explore their potential relevance to sustained implementation quality. Though several relationships attained statistical significance at particular points in time, none were stable across cohorts. The role of PROSPER's continuous, proactive technical assistance in producing the positive results is discussed.

Study timeline showing temporal relationships between team factor assessment waves and implementation cohorts of the family-focused and school-based interventions. Shaded regions denote academic years, during which all interventions were conducted. Arrows indicate which team factor assessment wave data were used to predict individual cohort’s implementation quality outcome data in analyses. The instructor-related implementation factors were assessed during implementation of the school-based interventions, and were used to predict school-based implementation quality outcomes observed in the same cohort.
