Biofeedback in Grandmothers Raising Grandchildren: Evaluating Intervention Parameters

This study examined the six critical parameters for evaluating interventions, including necessity, acceptability, feasibility, safety, fidelity, and effectiveness, of a heart rate variability (HRV) biofeedback training intervention in a sample of 20 grandmothers who were the primary caregivers of their grandchildren. After the grandmothers completed the HRV biofeedback training, they answered open-ended questions to provide data on the six parameters during face-to-face interviews. The findings of the study provided evidence for the necessity, acceptability, feasibility, safety, fidelity, and effectiveness of the HRV biofeedback intervention for reducing the stress experienced by grandmothers in raising their grandchildren.
