Adaptation and Validation of Moroccan Dialect Compulsive Internet Use Scale: Validity and Reliability

Objective: The current study aimed to examine the factor structure and reliability of Arabic version of Compulsive Internet Use Scale (CIUS) among a sample of Moroccan high school students. Methods and Materials: 334 students from three public High school of Casablanca Region (Morocco) were included. 40.9% of boys and 59.1% of girls (M=17.15, SD=1.328) responded to an Arabic translated version of CIUS. Descriptive, exploratory, and confirmatory factor analyses were performed on the collected data, by measuring the ratio Chi-square and degree of freedom χ2 /DF, Comparative Fit Index (CFI), The Normed Fit Index (NFI), Tucker-Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA). Findings: The exploratory and confirmatory factor analyses support a model with 14 items showing the three-dimensional structure of this scale: Absorption, priorities and mood regulation. The Arabic CIUS follows a three-dimensional structure, demonstrates measurement invariance with respect to sex and age, and exhibits excellent reliability (ω = .94). The values of validity indexes were: χ2 /DF= 3.26, CFI = 0.971, NFI = 0.937, TLI = 0.938, and RMSEA = 0.043. Conclusion: These subscales indicate generally satisfactory psychometric qualities. These results show that the Arabic translated CIUS instrument has an excellent factor structure and internal consistency.
