Bidirectionality Between Perceived Immediate and Long-Term Benefits and Losses and Internet Gaming Disorder Among Chinese Adolescent Gamers: Prospective Longitudinal Study.

Stronger perceived immediate benefits of mental health and personal achievement at baseline significantly predicted more IGD symptoms one year later.

• Mental health immediate benefits: β=.08, 95% CI 0.01-0.15
• Personal achievement immediate benefits: β=.10, 95% CI 0.01-0.20
• These were the only two perceived benefit/loss dimensions that prospectively predicted IGD (not the reverse)
• Analysis used cross-lagged panel models adjusting for background factors

More IGD symptoms at baseline significantly predicted stronger perceived immediate and long-term benefits of social relationships and personal achievement at follow-up.

• Immediate social relationship benefits: β=.09, 95% CI 0.03-0.15
• Long-term social relationship benefits: β=.11, 95% CI 0.05-0.17
• Immediate personal achievement benefits: β=.12, 95% CI 0.06-0.18
• Long-term personal achievement benefits: β=.10, 95% CI 0.04-0.16

More IGD symptoms at baseline significantly predicted stronger perceived immediate and long-term losses across mental health, sleep quality, academic performance, and family relationships at follow-up.

• Mental health losses — immediate: β=.09, 95% CI 0.03-0.15; long-term: β=.08, 95% CI 0.02-0.14
• Sleep quality losses — immediate: β=.10, 95% CI 0.04-0.16; long-term: β=.13, 95% CI 0.07-0.19
• Academic performance losses — immediate: β=.09, 95% CI 0.04-0.15; long-term: β=.07, 95% CI 0.01-0.13
• Family relationship losses — immediate: β=.11, 95% CI 0.05-0.17; long-term: β=.10, 95% CI 0.04-0.16

More IGD symptoms at baseline significantly predicted stronger perceived long-term losses in social relationships at follow-up.

• Long-term social relationship losses: β=.08, 95% CI 0.02-0.14
• No significant effect was found for immediate social relationship losses predicting IGD or IGD predicting immediate social relationship losses
• This finding extended the pattern of IGD predicting perceived losses into the social domain at the long-term time perspective

The study used a 12-month two-wave prospective longitudinal design among Chinese junior middle school adolescent gamers.

• Baseline survey conducted December 2018 (T1); follow-up survey conducted December 2019 (T2)
• Final sample size was 1173 students (mean age 12.5, SD 0.6 years; 59.1% male)
• Students were from conveniently selected schools in Guangzhou and Chengdu, China
• All Grade 7 and 8 students who had played internet games in the past 12 months were invited to self-administer questionnaires in a classroom setting without teachers present
• IGD was assessed using the 9-item DSM-5 IGD checklist

The study found that the predictive effects of IGD on perceived benefits and losses were predominantly unidimensional, with only two exceptions where perceived benefits predicted IGD.

• IGD at T1 predicted perceived immediate and long-term benefits and losses across most domains at T2
• Only perceived immediate benefits of mental health and personal achievement at T1 showed reverse prediction of IGD at T2
• No perceived losses domains significantly predicted subsequent IGD symptoms
• The authors describe these findings as revealing 'the unidimensional predictive effects of IGD on perceived immediate and long-term benefits and losses, with 2 exceptions'

The study integrated time perspective (immediate vs. long-term) into both perceived benefits and losses of internet gaming, a cognitive dimension described as previously overlooked in the literature.

• Benefits were assessed across 3 domains: mental health, social relationships, and personal achievement
• Losses were assessed across 6 domains: mental health, sleep quality, academic performance, family relationships, social relationships, and personal achievement
• Each domain was assessed for both immediate and long-term time perspectives
• The authors describe this integration as 'innovative' and 'a cognitive dimension previously overlooked in literature'
