Objective: This article performs a systemic review of psychometric properties and factor structure of the Compulsive Internet Use Scale (CIUS), the scale for assessing Internet addiction behavior in clinics and research fields. Method: Studies measuring psychometric properties and factor structure of CIUS (original version) were searched through MEDLINE in PubMed, SCOPUS, Pub Psych, google scholar and SID & Iran medex (Iranian database). A total of 18 studies (24 samples) including 44,198subjects were reviewed in our study. Results: Based on meta-analysis for internal consistency, the pooled Cronbach's alpha coefficient from all study was 0.47(95percent confidence interval [CI], 0.46-0.49). Based on meta-analysis for internal consistency adolescence subgroup was 0.48 (95percent confidence interval [CI], 0.45-0.51), and addicted to behavior addiction subgroup was 0.48 (95 percent CI, 0.44-0.51), in general population subgroup was 0.47(95percent confidence interval [CI], 0.42-0.53), in university student subgroup was 0.47(95percent confidence interval [CI], 0.43-0.51), in internet user was 0.45(95percent confidence interval [CI], 0.43-0.47), by cultural of country for collectivistic society was 0.49(95percent confidence interval [CI], 0.46-0.52), and individualistic societies was 0.46 (95 percent confidence interval [CI], 0.44-0.47) and based quality assessment subgroup for study was 0.47(95percent confidence interval [CI], 0.46-0.49). Discussion: Future studies should be conducted on the multiethnic population and cross-cultural designee. Future studies should be developed and reported based on the COSMIN checklist.
