Real-time personalized feedback in mHealth for adolescents

Abstract

Mobile Health (mHealth) interventions have the potential to improve early identification, prevention, and treatment of mental health problems. Grow It! is a multiplayer smartphone app designed for youth aged 12–25, allowing them to monitor their emotions and engage in daily challenges based on Cognitive Behavioral Therapy (CBT) principles. Recently, a personalized mood profile was added to improve the app. We investigated whether real-time personalized feedback on mood enhances app engagement, user experience, and the effects on affective and cognitive well-being. Sample A ( N = 1269, age = 18.60 SD = 3.39, 80.6% girls, 95.4% Dutch) played the original app without feedback on their mood, and an independent Sample B ( N = 386, age = 16.04 SD = 3.21, 67.6% girls, 82.9% Dutch) received the renewed version with personalized real-time feedback on their mood. Participants who received personal feedback did not have higher app engagement ( t(1750,400) = 1.39, P = .206, d = 0.07; t(692,905) = 0.36, P = .971, d = 0.0) nor higher user experience ( t(177,596) = 0.21, P = .831, d = 0.02; ( t(794) = 1.28, P = .202, d = 0.12; χ 2 (659,141) = 2.83, P = .091). Players of the renewed version (Sample B) experienced significant improvements in affective ( t(175) = 3.01, P = .003, d = 0.23) and cognitive well-being ( t(175) = 3.48, P = <.001, d = 0.26) over the course of three weeks. The renewed version Grow It! has the potential to enhance youths’ affective and cognitive well-being. However, adding real-time insights did not seem to affect app engagement nor user experience.
