GD, gaming disorder, measured with Gaming disorder test. Onset, onset of problematic gaming. Functioning, everyday functioning measured with GAF and CGAS. ADHD, attention deficit hyperactivity disorder, measured with ASRS. ASD, autism spectrum disorder, measured with RAADS-14.The * indicates that the p-value is statistically significant. The bold values are the values that are significant.
