Mobile HCI in Social Media and Youth Mental Health Intervention Practices

Abstract

From the mobile human-computer interaction (Mobile HCI) perspective, this study examines social media's impact on youth mental health and its intervention practices. A stratified survey of 2,250 young people (14-28 years) was conducted, along with a 3-month intervention experiment on 480 high-risk subjects and platform ecological assessment. SEM and repeated measures ANOVA reveal that active social media HCI modes (creative/interactive behaviors) benefit youth self-identity, while passive modes (consumptive/dependent behaviors) trigger psychological risks via social comparison and algorithmic interaction. The proposed stepwise intervention pathway demonstrated significant effectiveness, achieving a 30.7% reduction in anxiety scores among the intervention group. This study provides practical references for Mobile HCI research and youth mental health protection.
