Abstract

OBJECTIVE: To investigate the prevalence of negative emotions and mobile phone addiction among adolescents and explore the longitudinal association between the two. METHEDS: A random cluster sampling method was employed to administer the Depression, Anxiety and Stress Scale (DASS-21) and Mobile Phone Addiction Index (MPAI) to 2115 secondary school pupils (junior and senior high) across three mainstream secondary schools in Xinxiang City during December 2022 (T1) and December 2023 (T2). Depression-Stress Simplified Chinese Version (DASS-21) and Mobile Phone Addiction Index (MPAI) to conduct a two-stage longitudinal study among 2115 secondary school students (junior and senior high) from three general secondary schools in Xinxiang City. Data were analysed using a cross-lagged panel model. RESULTS: (1) The study encompassed 2115 adolescents, predominantly junior secondary school pupils (58.8%), with an average age of (14.89±2.31) years. Among them, 1091 were male (51.6%) and 1024 female (48.4%), the vast majority being non-only children (92.4%). Their current residence was predominantly rural (54.0%), and their parents' educational attainment was chiefly at junior secondary level. and 1024 females (48.4%). The vast majority were non-only children (92.4%), with 54.0% residing in rural areas. The educational attainment of participants' parents was predominantly at junior secondary level. (2) At Time Point 1 (T1), adolescents' scores for depression, anxiety, stress, and mobile phone addiction were (5.52±3.47), (6.88±5.72), (7.43±4.49), and (34.49±12.31) points respectively. At T2, these scores significantly increased to (8.43±3.26), (9.62±3.88), (11.14±3.45), and (40.51±13.55) points respectively (P<0.01). (3) Cross-lagged analysis revealed that depression at T1 significantly and positively predicted mobile phone addiction at T2 (β=0.34, P<0.01), while mobile phone addiction at T1 also significantly and positively predicted depression at T2 (β=0.24, P<0.05). (4) Anxiety at T1 significantly and positively predicted mobile phone addiction at T2 (β=0.22, P<0.01), whereas the predictive effect of T1 mobile phone addiction on T2 anxiety was non-significant (β=0.07, P> 0.05). (5) T1 stress significantly and positively predicted T2 mobile phone addiction (β=0.37, P<0.01), whilst T1 mobile phone addiction also significantly and positively predicted T2 stress (β=0.41, P<0.01). CONCLUSION: A stable reciprocal predictive relationship exists among adolescent depression, stress, and mobile phone addiction, whereas adolescent anxiety only unidirectionally predicts mobile phone addiction.
