Abstract

Background: University students frequently experience psychological distress. With the internet embedded in daily life, online activities, including online shopping may be used as coping strategies, but excessive use can contribute to internet addiction. Mechanism-oriented research also suggests that general online exposure may influence online impulsive buying through proximal processes such as internet addiction. Purpose: This study aimed to determine factors associated with internet addiction among university students and to test whether internet addiction mediates the association between general online exposure (hours/day) and online impulsive buying. Methods: A quantitative cross-sectional design was used among 386 university students at a campus in Kasihan, Bantul, Yogyakarta, Indonesia (January-April 2024) using convenience sampling. Internet addiction was measured using the Indonesian Internet Addiction Test (IAT) validated by Siste et al. (2021) (18 items; three-factor structure; Cronbach’s α=0.855). Online impulsive buying was measured using the Impulse Buying Tendency Scale (IBTS) adapted to online context. Psychological distress was measured using the Depression Anxiety Stress Scale (DASS-42). Spearman correlations were used for bivariate analysis. Multiple linear regression identified predictors of internet addiction. A simple mediation model (PROCESS Model 4; 5,000 bootstrap samples) tested Duration → internet addiction → online impulsive buying, controlling for age, sex, DASS total, and online loan history. Results: Mean internet addiction score was 40.57 (SD 13.86) and mean online impulsive buying score was 37.02 (SD 8.91). Internet addiction correlated significantly with online impulsive buying (ρ=.369, p<.001), depression (ρ=.163, p=.001), anxiety (ρ=.131, p=.010), stress (ρ=.147, p=.004), and Duration (ρ=.131, p=.010). In multivariable regression, online impulsive buying (B=0.673, p<.001) and stress (B=0.210, p=.002) were significant predictors of internet addiction (R²=.215). In mediation analysis, the indirect effect of duration on online impulsive buying through internet addiction was significant (ab=0.1006, 95% bootstrap CI [0.0085, 0.2154]), consistent with an indirect-only mediation pattern. Conclusions: Online impulsive buying and stress were significantly associated with internet addiction, with online impulsive buying as the strongest predictor. Internet addiction also mediated the association between general online exposure and online impulsive buying.

Abstract

Background: Indonesia exhibits high smartphone penetration (210.77 million users, 2021) and substantial online gaming engagement, with 26% of gamers aged 18–24 and 20% aged 25–34. Given alarming gaming disorder prevalence (IGD: 14.6% males, 6.2% females; GD: 7.2% males, 2.8% females) and limited research on productivity impacts in urban Indonesia, this study investigates online game addiction's effect on work productivity among young adults in South Jakarta. Methods: A cross-sectional correlational design recruited 95 participants via purposive sampling (aged 18–26, South Jakarta residents, >3 hours/day non-professional gaming). Data collection utilized the validated Indonesian Online Game Addiction Questionnaire (7-item, Cronbach’s α=0.73) and Individual Work Performance Questionnaire (18-item, Cronbach’s α=0.814–0.871). Normality was confirmed with Kolmogorov-Smirnov testing; SPSS v.28 facilitated Pearson correlation and linear regression analyses. Results: Participants were predominantly male (64.21%), high school-educated (72.63%), and private sector employees (61.05%). Key findings revealed: a significant weak negative correlation between online game addiction and work productivity (r = -0.291, p = 0.04); a strong positive correlation between addiction and gaming duration (r = 0.486, p < 0.001); no correlation between gaming duration and productivity (p = 0.312); and regression indicating addiction explains 9.7% of productivity variance (Adjusted R² = 0.088, β = -0.420, p = 0.002). Conclusion: Online game addiction significantly impairs work productivity among urban Indonesian youth, yet accounts for only 9.7% of variance—underscoring the influence of unaddressed mediators like sleep quality and motivation. Findings necessitate integrating psychiatric nursing interventions within workplace mental health frameworks.

Abstract

Background: Major depressive disorder in adolescents is often accompanied by emotional and behavioural problems. Excessive smartphone use may further aggravate these conditions and contribute to behavioural disturbances, including an increased risk of violent behaviour. Purpose: To describe the implementation of bibliotherapy as a non-pharmacological psychiatric nursing intervention for an adolescent with major depressive disorder, psychotic symptoms, a risk of violent behaviour, and high smartphone addiction. Method: This descriptive case study was conducted in Lily 3 Ward of Soerojo Hospital. A 15-year-old adolescent received bibliotherapy as part of comprehensive psychiatric nursing care for seven consecutive days. Baseline emotional and behavioural functioning was assessed using the Strengths and Difficulties Questionnaire (SDQ), while smartphone addiction was evaluated using the Smartphone Addiction Scale (SAS). Results: Baseline SDQ assessment showed normal emotional symptoms (score = 2) and hyperactivity (score = 4), abnormal conduct problems (score = 6) and prosocial behaviour (score = 3), as well as borderline peer problems (score = 4) and total difficulties (score = 16). The baseline SAS score was 104, indicating a high level of smartphone addiction before the nursing intervention. Conclusion: The baseline findings demonstrated emotional and behavioural difficulties, particularly conduct problems, impaired prosocial behaviour, borderline overall difficulties, and high smartphone addiction in an adolescent with major depressive disorder. These findings support the implementation of bibliotherapy as part of comprehensive psychiatric nursing care to address the patient's emotional and behavioural needs. Keywords: Adolescents; Bibliotherapy; Major Depressive Disorder; Risk of Violent Behaviour; Smartphone Addiction.
