SMYLS: A Self-management Program for Youth Living With Sickle Cell Disease

Not Applicable
Completed
Conditions
Sickle Cell Disease
Interventions
Behavioral: Voice Crisis Alert V2
Registration Number
NCT04289311
Lead Sponsor
Medical University of South Carolina
Brief Summary

The purpose of this study is to find out whether a web-based intervention using a mobile device is helpful for teens learning to care for and manage symptoms of sickle cell disease. The intervention lasts 12 weeks with a 3-month follow up period, and uses a smartphone or a tablet.

Detailed Description

The purpose of the proposed study is to test the feasibility of SMYLS, an mHealth intervention designed to facilitate self-management behaviors in children and adolescents with sickle cell disease (SCD). Specifically, the investigators propose to test the feasibility of the intervention for improving transition from parent-managed to adolescent self-managed care. In addition, the investigators will evaluate the communication that takes place via the intervention between adolescents, their parents/caregivers, and healthcare providers. The investigators will work with the MUSC Pediatric Sickle Cell Clinic to identify and recruit 5 healthcare providers of children with SCD and 30 dyads of adolescents ages 11 - 17 SCD and their parent/caregiver (n = 60).

Each item is scored individually and is worth 1 to 5 points. There are 3 subdomains; subdomain scores are summed for the total score, which ranges from 0 - 90 points. Higher scores = improvement
