Evaluation of psychometric properties of the Arabic version of the Internet Disorder Scale (IDS-15)

The internet in modern society has impacted individuals of all ages, especially youth. Over the past 25 years, internet has become increasingly accessible, affordable, and available to a large proportion of individuals worldwide. Despite the clear advantages the internet has brought, adverse effects including potential disordered internet use have been noted among a minority of users. This has led to an increase in the development of screening instruments and numerous validation studies in many countries. Although Arabic is spoken in 25 countries worldwide, little research has been carried out, probably because there is a lack of Arabic instruments assessing problematic internet use. The present study evaluated the psychometric properties of the Arabic version of the 15-item Internet Disorder Scale (IDS-15). A cross-sectional study was conducted among 327 active internet users (35.5 % male; mean age = 21.49 years [SD = 3.06]) using a pen-and-paper-based survey. All participants completed the IDS-15, Bergen Social Media Addiction Scale (BSMAS), and Satisfaction with Life Scale (SWLS). The concurrent validity of the Arabic IDS-15 was satisfactory as its total score was significantly correlated with scores on the BSMAS (standardized coefficient [β] = 0.382), time spent online (β = 0.310), time spent on social media (β = 0.368), time spent on sleep (β = −0.176), and SWLS score (β = −0.281). The internal consistency indicated good internal reliability. Confirmatory factor analysis supported the factor structure of the IDS-15. The Arabic version IDS-15 is a psychometrically sound and robust instrument for assessing internet disorder due to its excellent concurrent validity, good reliability, and satisfactory construct validity.
