Comparison of the Effectiveness of Self-determination Theory Training and Acceptance and Commitment Therapy on Sleep Quality and Academic Hope in Students with Internet Gaming Disorder with and without Comorbidity of Attention Deficit / Hyperactivity Disorder

The increasing use of the Internet by students can lead to problems such as addiction and dependence, which can have an adverse effect on their academic and personal achievements. 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).

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.

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).

SDT training and ACT can both benefit students with Internet gaming disorder and have a significant impact on their sleep quality and academic hope.
