Therefore, this study aimed to compare the effectiveness of self-determination theory (SDT) training and Acceptance and Commitment Therapy (ACT) on sleep quality and academic hope in students with Internet gaming disorder (IGD) with and without comorbidity of Attention Deficit / Hyperactivity Disorder (ADHD). Method: The study was designed as a quasi-experimental pre-test-post-test study with a control group and a follow-up phase. The statistical population consisted of all students aged 12 to 14 years with IGD in Khorramabad in 2019 (N=5200); From which 42 children were selected by purposive sampling method and randomly assigned to two experimental groups (n=28) and one control group (n=14).The instruments used included IGD-20 Test (Pontes et al. 2014), the Child Symptom Inventory-4 (CSI-4; Sprafkin & Gadow, 1994), Academic Hope Scale (AHS, Khormaei & Kamari, 2018) and Pittsburgh Sleep Quality Index (PSQI, Buysse et al, 1989). The intervention groups received 9 two-hour sessions of SDT training (intervention group 1) and ACT (intervention group 2)). Data analysis was performed using analysis of covariance in SPSS26 environment. Results: The results of data analysis showed that in both groups of SDT training and ACT, there was a significant difference between the two stages of post-test and follow-up in sleep quality and academic hope (p <0.0001); Also, by controlling the effect of pretest, the interaction of two variables of group membership and comorbidity of ADHD group in students' academic hope was significant (p <0.0001). Conclusion: SDT training and ACT can both benefit students with Internet gaming disorder and have a significant impact on their sleep quality and academic hope. %> http://childmentalhealth.ir/article-1-1197-en.pdf %P 67-83 %& 67 %! %9 Research %L A-10-1889-2 %+ Department of Psychology, Ahvaz Branch, Islamic Azad University, Ahvaz, Iran %G eng %@ 2423-3552 %[ 2022
