Participant Satisfaction in a Cardiovascular Disease Prevention Intervention for Midlife Black Women.

Background: Midlife Black women suffer disproportionately from cardiovascular disease and are 65% more likely to die following a cardiac event compared with White women. Recruitment and retention of midlife Black women in clinical trials has been historically low. The culturally tailored Midlife Black Women's Stress Reduction and Wellness (B-SWELL) intervention was codeveloped with the community and designed to lower cardiovascular disease risk in midlife Black women.

Objectives: We sought to assess participant satisfaction in the randomized feasibility trial of the B-SWELL intervention.

Methods: A feasibility trial comparing the B-SWELL to a wellness intervention was conducted in the winter and spring of 2021 in compliance with pandemic research protocols. An adapted survey tool was used to rate satisfaction with the intervention and its technology using a Likert-type scale (1 [strongly disagree] to 5 [strongly agree]). Survey subscales assessed usefulness, ease, and acceptability of the intervention(s).

Results: Randomization yielded no statistical demographic differences (N = 48). Satisfaction for the interventions was high in both the B-SWELL and Wellness intervention groups with mean scores of 4.57 and 4.56, respectively. Mean scores for technology were 4.49 for the B-SWELL and 4.47 for the Wellness group. Subscales were also rated highly. Narrative responses were positively aligned with satisfaction scores.

Conclusions: Results support use of cultural adaptation and community participatory methods to develop and deliver interventions targeted to at-risk populations. Culturally adapted interventions designed in collaboration with the community have greater authenticity, increasing the potential for higher recruitment, retention, and participant satisfaction of underrepresented populations. The trial is registered in ClinicalTrials.gov (NCT04404478).
