Abstract The 14-item Compulsive Internet Use Scale (CIUS) is one of the most frequently internationally adapted psychometric instruments developed to assess generalized problematic Internet use. Multiple adaptations of this instrument have led to versions in different languages (e.g., Arabic and French), and different numbers of items (e.g., from 5 to 16 items instead of the original 14). However, to date, the CIUS has never been simultaneously compared and validated in several languages and different versions. Consequently, the present study tested the psychometric properties of four CIUS versions (i.e., CIUS-14, CIUS-9, CIUS-7, and CIUS-5) across eight languages (i.e., German, French, English, Finnish, Spanish, Italian, Polish, and Hungarian) to (a) examine their psychometric properties, and (b) test their measurement invariance. These analyses also identified the optimal versions of the CIUS. The data were collected via online surveys administered to 4,226 voluntary participants from 15 countries, aged at least 18 years, and recruited from academic environments. All brief versions of the CIUS in all eight languages were validated. Dimensional, configural, and metric invariance were established across all languages for the CIUS-5, CIUS-7, and CIUS-9, but the CIUS-5 and CIUS-7 were slightly more suitable because their model fitted the ordinal estimate better, while for cross-comparisons, the CIUS-9 was slightly better. The brief versions of the CIUS are therefore reliable and structurally stable instruments that can be used for cross-cultural research across adult populations. [less ▲]

Background and aims Despite many positive benefits, mobile phone use can be associated with harmful and detrimental behaviors. The aim of this study was twofold: to examine (a) cross-cultural patterns of perceived dependence on mobile phones in ten European countries, first, grouped in four different regions (North: Finland and UK; South: Spain and Italy; East: Hungary and Poland; West: France, Belgium, Germany, and Switzerland), and second by country, and (b) how socio-demographics, geographic differences, mobile phone usage patterns, and associated activities predicted this perceived dependence. Methods A sample of 2,775 young adults (aged 18-29 years) were recruited in different European Universities who participated in an online survey. Measures included socio-demographic variables, patterns of mobile phone use, and the dependence subscale of a short version of the Problematic Mobile Phone Use Questionnaire (PMPUQ; Billieux, Van der Linden, & Rochat, 2008). Results The young adults from the Northern and Southern regions reported the heaviest use of mobile phones, whereas perceived dependence was less prevalent in the Eastern region. However, the proportion of highly dependent mobile phone users was more elevated in Belgium, UK, and France. Regression analysis identified several risk factors for increased scores on the PMPUQ dependence subscale, namely using mobile phones daily, being female, engaging in social networking, playing video games, shopping and viewing TV shows through the Internet, chatting and messaging, and using mobile phones for downloading-related activities. Discussion and conclusions Self-reported dependence on mobile phone use is influenced by frequency and specific application usage. [less ▲]

BACKGROUND AND AIMS: The aim of this study was to identify problematic gaming behavior among Finnish adolescents and young adults, and evaluate its connection to a variety of psychological, social, and physical health symptoms. METHODS: This cross-sectional study was conducted with a random sample of 293 respondents aged from 13 to 24 years. Participants completed an online survey. Problematic gaming behavior was measured with the Game Addiction Scale (GAS). Self-reports covered health measures such as psychological health (psychopathological symptoms, satisfaction with life), social health (preferences for social interaction), and physical health (general health, Body Mass Index [BMI], body discomfort, physical activity). RESULTS: Problematic gaming behavior was found to relate to psychological and health problems, namely fatigue, sleep interference, depression and anxiety symptoms. Multiple linear regression indicated that the amount of weekly gaming, depression and a preference for online social interaction predicted increased problematic gaming symptoms. CONCLUSIONS: This research emphasized that problematic gaming behavior had a strong negative correlation to a variety of subjective health outcomes. [less ▲]
