Internet Addiction Test-Adolescence (IAT-A)

The Internet Addiction Test-Adolescence (IAT-A) is a 20-item instrument to measure how internet use affects adolescents and pre-teens in terms of their daily routine, social life, productivity, sleeping patterns, and feelings. The wording of this measure has been modified from the original IAT (Young, 1998) to be more relevant to a younger population.
