Stress Management and Mindfulness Intervention for Patients With Sickle Cell Disease

After consenting and completing the baseline measures, participants will be assigned (like flipping a coin) to the immediate treatment group or the control group. The immediate treatment group will participate in the intervention for six weeks while the control group waits. At the end of six weeks, both groups will complete the measures again, and then the control group will have a chance to participate in the intervention. See table below for the timeline of the study for each group.

Intervention: The intervention is a stress management and mindfulness-based program developed and led by Dr. Melissa Hunt, who is a licensed clinical psychologist with expertise in chronic health conditions and mindfulness interventions. She will be assisted by four research coordinators who are undergraduate psychology majors at the University of Pennsylvania. Participants will also have access to an app called Blackfulness. It is a mindfulness meditation app designed specifically for black people. The in person sessions will take place in person at The Neural and Behavioral Sciences (NBS) Building (425 S University Ave, Philadelphia, PA 19104) Room 450. Remote sessions will take place virtually via Zoom video conferencing. People who elect the in person sessions may choose to attend some sessions remotely if weather or health necessitates it.
