The purpose of this study was to understand the impacts, outcomes, and strategies for sustainability post-federal funding. Although a complete census of HCAP coalitions was not achieved, the 63 percent response rate on the survey and high levels of cooperation for interviews and site visits produced a valid representation of the perspectives of the study respondents. However, it is unknown whether the respondents that completed the survey are a representative sample of the full population of HCAP grantees. Therefore, it is possible that non-response is related to the coalition-specific characteristics and may bias the analysis. Causes for non-response are unlikely to affect the findings related to the key research questions as the coalitions that did not complete the questionnaire were distributed across all grantee cohorts.2 Additionally, given that the coalitions were funded up to ten years ago through HCAP, it is possible that the staff who completed the survey did not work on the program originally. No efforts were made to validate the survey data through administrative records or public data. However, out of the 25 key informant interviews, only one coalition’s sustainability status needed to be corrected from their survey response of sustained to not sustained based on the interview discussion. If one of every 25 surveys were misclassified, roughly 6 coalitions would be misclassified. This is not expected to affect the analyses as characteristics and themes shared across sustained and shared across not sustained are being considered rather than individual coalition characteristics.
