Mobile Health Use Predicts Self-Efficacy and Self-Management in Adolescents with Sickle Cell Disease

Background: Sickle cell disease (SCD) is associated with medical challenges that often worsen for adolescents and young adults (AYA) when caregivers begin to transfer responsibility for care. Living with SCD requires self-management and self-efficacy and is a critical concern for AYA as they navigate complex medical systems. However, previous research indicates that AYA with SCD often lack the ability, confidence, and skills to manage their disease effectively. As most AYA with SCD are now “technology natives,” mobile health (mHealth) holds considerable promise for assessing and changing behaviors to improve health outcomes. In a previous feasibility and acceptability study, AYA with SCD provided qualitative feedback that they would use mHealth (a co-designed mobile app) and that it was beneficial for tracking health behaviors. Thus, we integrated the mHealth app into a group intervention (SCThrive) and hypothesized that more engagement with the mHealth app would result in increased self-management and self-efficacy for AYA with SCD. Methods: Our analysis from a single-site, randomized control trial (NCT02851615) assessed data from only AYA in the treatment arm (N = 26) who received the SCThrive intervention and used the mHealth app. The sample included AYA with SCD aged 13 to 21 years (Mage = 16.7 years; 54% female; 46% HbSS genotype; all African American/Black) who received six-weekly group sessions (3 in-person, 3 online). All SCThrive participants were provided with the mobile app (iManage) on an iPad. The Transition Readiness Assessment Questionnaire (TRAQ-5) assessed self-management skills and the Patient Activation Measure (PAM-13) assessed self-efficacy at baseline and posttreatment. We also assessed engagement (logins), confidence and completion of self-management goals (e.g., exercising, take medications), pain diary entries, and mood symptoms recorded on the iManage app (see Figure 1). Results: Preliminary analyses indicated that most AYA with SCD logged on to the iManage app (Mlogins = 7.8, SD = 9.1, range = 1 - 45) and viewed their pain diary (Mviews = 5.7, SD = 9.1, range = 1 - 45) at least once a week. Eighty-eight percent of AYA saved a pain diary entry and the most commonly used strategies for managing pain episodes were resting (22%), drinking water (19%), and using distraction (8%). AYA viewed their self-management goals about once every 11 days (Mdays = 11.24, SD = 13, range = 0 - 57). All AYA created (Mgoals = 5.7, SD = .72, range = 4
