Hyperactivity/inattention and self-esteem problems seem to be important for the development of IGD. We found first empirical evidence that IGD could prospectively contribute to a deterioration of adolescent mental health. Only a subgroup of affected adolescents showed IGD consistently over 1 year.
IGD appears to be associated with internalizing and externalizing problems in adolescents. Moreover, the findings of the present study provide first evidence that not only adolescent but also parental mental health is relevant to IGD in early adolescence. Adolescent and parental mental health should be considered in prevention and intervention programs for IGD in adolescence.
Background: Pathological internet use is of increasing significance in several industrial nations. Sampling and Methods: We surveyed a representative German quota sample of 1,723 adolescents (aged 14-17 years) and 1 caregiver each. We conducted a latent profile analysis to identify a high-risk group for pathological internet use. Results: Overall, 3.2% of the sample formed a profile group with pathological internet use. In contrast to other published studies, the results of the latent profile analysis were verified not only by self-assessments of the youth's but also by external ratings of the caregivers. In addition to the pathological internet use, the high-risk group showed lower levels of family functioning and life satisfaction as well as more problems in family interactions. Conclusions: The results showed a considerable prevalence of pathological internet use in adolescents and emphasized the need for preventive and therapeutic approaches.
Excessive Internet use and Internet addiction are currently increasing in many industrial nations. Verified and validated measuring instruments could contribute to a better understanding of this still quite recent development. The aim of this survey was to investigate the psychometric properties of a German version of the Compulsive Internet Use Scale (CIUS). We surveyed a representative German quota sample of 1,723 adolescents aged between 14 and 17 years, as well as one parent each, with standardized questionnaires. In addition, adolescents and parents were asked whether the media use by the youth was considered problematic or excessive, and whether it led to arguments at home. We conducted confirmatory factor analyses (CFA) with maximum likelihood estimation to examine the factorial validity of the German CIUS, as well as reliability and correlation analyses. The results of the CFA indicate good psychometric properties for the German version of the CIUS. They appear in line with the findings for the original version of the questionnaire. Furthermore, the CIUS showed high internal consistency, and we found significant correlations between the "CIUS-summary score" and different ratings of problems with the media usage by the youth and the parents. The German version of the CIUS seems to be a valid and suitable diagnostic tool for measuring problematic to pathological Internet use.
Internet Gaming Disorder (IGD) has been included in the current edition of the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5). In the present study, the relationship among social support, friends only known through the Internet, health-related quality of life, and IGD in adolescence was explored for the first time. For this purpose, 1,095 adolescents aged from 12 to 14 years were surveyed with a standardized questionnaire concerning IGD, self-perceived social support, proportion of friends only known through the Internet, and health-related quality of life. The authors conducted unpaired t-tests, a chi-square test, as well as correlation and logistic regression analyses. According to the statistical analyses, adolescents with IGD reported lower self-perceived social support, more friends only known through the Internet, and a lower health-related quality of life compared with the group without IGD. Both in bivariate and multivariate logistic regression models, statistically significant associations between IGD and male gender, a higher proportion of friends only known through the Internet, and a lower health-related quality of life (multivariate model: Nagelkerke's R = 0.37) were revealed. Lower self-perceived social support was related to IGD in the bivariate model only. In summary, quality of life and social aspects seem to be important factors for IGD in adolescence and therefore should be incorporated in further (longitudinal) studies. The findings of the present survey may provide starting points for the development of prevention and intervention programs for adolescents affected by IGD.
