Using qualitative comparative analysis to uncover multiple pathways to program sustainment: implications for community-based youth substance misuse prevention

Abstract

Abstract Background In order to achieve wide-scale impact in community settings, programs must be sustained. Theory and empirical evidence suggest that intervention characteristics, organizational context, capacity for program implementation, and processes related to implementation are associated with continued program delivery. However, few studies examine how combinations of these factors work together in different settings to influence program sustainment. Methods Using scales specified in the Program Sustainability Assessment Tool (PSAT), the current cross-sectional study aims to identify the necessary and sufficient conditions for the sustainment of the Strengthening Families Program for Parents and Youth 10-14 (SFP 10-14). Staff (n = 59) at SFP 10-14 implementation sites across Washington State completed an online survey reporting on their current level of SFP 10-14 sustainment. They also completed PSAT, with eight scales designed to assess conditions that consistently produce sustainment. Data were analyzed using qualitative comparative analysis. Results Environmental support was the only necessary condition for sustainment success. Four solutions sufficient to achieve sustainment were also identified. These included the combined presence of (1) environmental support, organizational capacity, and funding stability; (2) environmental support, organizational capacity, communication, and program evaluation, in the absence of strategic planning; (3) environmental support, organizational capacity, program evaluation, and partnerships, in the absence of strategic planning; and (4) environmental support, communication, partnerships, and funding stability, in the absence of program evaluation. Conclusions Environmental support in combination with organizational capacity appeared to most consistently produce sustainment of SFP 10-14 programs in Washington State. Program providers will benefit from a focusing on enhancing those conditions to increase program sustainment.
