This study aimed to assess pathological Internet and cell-phone use in college students, and to identify psychological, health, and behavioral correlates. A cross-sectional design was utilized to gather data from 337 students. We developed two measures, termed the Internet Over-use Scale (IOS), and the Cell-Phone Over-Use Scale (COS). Additional measures utilized were the Beck Anxiety Inventory, the Beck Depression Inventory, and the General Health Questionnaire-28. Results provide support for internal consistency of the IOS and the COS (α = 0.88 and α = 0.87, respectively) as well as for construct validity. Logistic regression analyses indicated that heavy Internet use is associated with high anxiety; high cell-phone use is associated to being female, and having high anxiety and insomnia. The developed measures seem to be promising tools for assessing these new behavioral addictions.

This study presents the results of a systematic review on the prevalence of sexual abuse experienced in adulthood by individuals with intellectual disability. An electronic and manual search of academic journals was performed on four databases via EBSCO Host: Academic Search Complete, PsycINFO, Medline, CINAHL Full-Text. In addition, PubMed, ProQuest, and Web of Science (core collection) were searched. After an initial selection of 1037 documents, 25 articles remained for quantitative synthesis. The combined prevalence of sexual abuse in adults with intellectual disability was 32.9% (95% CI: 22.7–43.0) and sensitivity analysis revealed that the prevalence was not outweighed by a single study. Overall, the United Kingdom had the highest prevalence (r = 34.1%), and the USA had the lowest (r = 15.2%). The overall prevalence in females was lower (r = 31.8%) than that in males (r = 39.9%). Subgroup analyses revealed that prevalence of sexual abuse was higher in institutionalized individuals. The most prevalent profile of abuser is of a peer with intellectual disability. Prevalence increases from mild to severe levels of intellectual disability and decreases in profound levels. It is also more prevalent when the informant is the individual with intellectual disability than when someone else reports abuse. In sum, one in three adults with intellectual disability suffers sexual abuse in adulthood. Special attention should be paid for early detection and intervention in high risk situations.
