The current study examined the association between hours spent online (HOS), positive parenting, negative parenting, autism parental stress and Internet addiction among Singapore based boys and girls (aged 6 to 14 years old) with Autism Spectrum Disorder (ASD). The research participants included 59 parents (41 females and 18 males) aged between 28 and 74 years old (mean age 37.95). Results indicated HOS, negative parenting and autism parenting stress predicted 54.8% of the total variance in Child Internet Addiction scores of children with ASD. Autism parental stress was the most significant predictor explaining 25.3% of the total variance with time spent online explaining another 23.5% and negative parenting predicted 6%. Positive parenting was not found to be significant. The findings reinforce the importance of according greater consideration for the role of parents when working with such children.
