3.2. Feasibility
RECRUITMENT
In regard to feasibility of recruitment, of the 109 individuals who completed screening, approximately 67% met initial eligibility criteria and completed the informed consent. An additional 20% of participants were identified as ineligible based on health problems or declined to participate following the consent appointment. In total, 53% of screened participants were included in the trial. Of these, 79% identified as white; 16% identified as black or African American, and 5% identified as “other.” Thus, while we met our feasibility success criteria for total sample size and recruitment rates, poor participant representation will need to be addressed in future trials. In regard to retention rates, across both arms 86.2% of the sample remained in the study until the 3-month endpoint, and 78% of the sample completed the intervention program. Higher rates of retention were evident in the MKNA arm, where 83% of the sample completed the program and 89.6% of the sample completed the study, compared to 72% and 82.7%, respectively, in the MKNE arm. Further, participants in the MKNA arm attended the program sessions more consistently, with 90.7% attendance in the MKNA arm compared to 76.7% attendance in the MKNE arm. Thus, only the MKNA arm achieved feasibility success criteria for retention.
