The Compulsive Internet Use Scale (CIUS)- Japan uses 14 items to assess compulsive use of the Internet. The scale excludes internet use for official activities. This measure was adapted from the original CIUS developed by Meerkerk at el. (2009) and contains 3 sub-scales: excessive absorption, difficulties in setting priorities, and mood regulation.
Geographies Tested: Japan
Populations Included: Female, Male
Age Range: Adolescents, Adults
Never - 0
Seldom - 1
Sometimes - 2
Often - 3
Very often - 4
Scores are summed, with a total score in the range 0–56. The CIUS does not have a predetermined cut-off score for Internet addiction. While a cut-off score of 28 was suggested since this score indicates that the specified Internet use behaviors occur on average at least ‘sometimes’, the author of CIUS suggested that the cut-off score should be carefully considered for respective countries.
