Corrigendum to “Model and approach for assessing implementation context and fidelity in the HEALing Communities Study” [Drug Alcohol Depend. 217 (2020) 108330](S0376871620304956)(10.1016/j.drugalcdep.2020.108330)

The authors regret that in the original published article there are errors in the section describing the baseline survey. The baseline survey response rate for the Kentucky site was erroneously reported as 43.8 %, which was calculated based on 189 responses and a denominator of 432 individuals from information extracted from the study's Participant Information Module (PIM). The PIM misidentified some individuals who were not actually invited to participate in the survey. The correct denominator for Kentucky was 326 individuals invited to participate, resulting in a response rate for Kentucky of 58.0 %. This error also impacted the combined response rate across the four sites, which was erroneously reported as 31.9 %, with 1,055 responses from 3,309 individuals invited. The overall response rate should have been calculated with a denominator of 3,203. The correct overall response rate for the baseline survey, therefore, was 32.9 %. These corrections do not impact the other papers in this Special Issue. The authors would like to apologise for any inconvenience caused.
