Abstract
BACKGROUND: Internet addiction (IA) is prevalent among adolescents but it is potentially revertible. Only three Taiwan adolescent studies reported IA remission and a few related factors. We investigated incidence and predictors of remission among Hong Kong Chinese secondary school students with a 12-month longitudinal study. METHODS: IA was defined as Chen Internet Addiction Scale (CIAS) score>63. Validated measures were used to assess students' psychosocial wellbeing at baseline and follow-up. RESULTS: Of 1545 students with IA at baseline, 1296 (83.9%) provided matched baseline/12-month follow-up data; their data were analyzed. Incidence of remission (CIAS≤63 at follow-up) was 59.29/100 person-years. Significant predictors included: 1) baseline CIAS score (ORa=.95), 2) baseline health belief model (HBM) constructs [perception of having severe IA (ORa=.34), perceived susceptibility to IA (ORa=0.82), perceived barrier (ORa=0.95), cue to action from parents (ORa=0.82), and self-efficacy for reducing Internet use (ORa=1.13)], and 3) baseline psychosocial health measures [self-esteem (ORa=1.03), severe depression (ORa=0.72) and social anxiety (ORa=0.96)] and their changes over time [depression (ORa=.95), anxiety (ORa=.94), loneliness (ORa=.93), self-esteem (ORa=1.07), positive affect (ORa=1.10) and family support (ORa=1.03)]. Two-thirds (64.3%) of the remission group presented reduced CIAS score>1.5 SD, and recorded larger improvements in psychosocial status over time than the non-remission group. CONCLUSION: Without noticeable interventions, incidence of remission was high and related to improvements in psychosocial health. Most of the HBM constructs, and baseline/changes in psychosocial measures predicted remission. Interventions to increase remission should modify these factors.
