Adolescents with autism spectrum disorder (ASD) often have various psychiatric comorbidities, particularly depression. In recent years, gaming disorder (GD) and Internet addiction (IA) have been identified as common comorbidities of ASD. We administered three self-administered screening instruments to adolescents with ASD to assess the severity of depression, GD, and IA. The participants were 10-18-year-olds with ASD. They were asked to complete three questionnaires to assess depressive symptoms, GD, and IA: the Patient Health Questionnaire for Adolescents (PHQ-A), Ten-Item Internet Gaming Disorder Test (IGDT-10), and Internet Addiction Test (IAT). The total IGDT-10 score was calculated in two different ways: the original scoring version (IGDT-10-OV) and the modified version (IGDT-10-MV). Of the 74 respondents, 24.3% had moderate or severe depressive symptoms, 8.1% were identified as having possible GD according to the IGDT-10-OV, 39.2% were identified as having possible GD according to the IGDT-10-MV, and 27.0% were positive for IA according to the IAT. Two-group comparisons revealed that depressive symptoms were more strongly associated with IA than with GD. IA was associated with more depressive symptoms than GD. Since adolescents with ASD have difficulties with social communication, they are prone to isolation and feelings of loneliness. Longer screen times due to social isolation may be a risk factor for the development of GD/IA. Adolescents with ASD often exhibit a preference for visual processing but may struggle with verbal communication. Thus, they may find online spaces more comfortable for them to alleviate their feelings of loneliness.
