This systematic review and meta-analysis aims to estimate the overall prevalence of Internet addiction among Iranian university students. A total of 49 articles written in Persian or English, without time limitation, were gathered. Databases of Scientific Information Database, MagIran, PubMed, Scopus, and Web of Science were searched during the period from February 13 to March 13, 2018. The following keywords and their possible combinations were used: Iran, student, Internet dependency, Internet addiction, and problematic Internet use. The Cochran's Q test was used to test the heterogeneity among the studies, and because heterogeneity was not significant, the random effects model was used to estimate the overall prevalence of Internet addiction. Data analysis was performed using STATA, version 12. Meta-analysis of 49 selected articles with a total sample size of 16,585 indicated that the overall prevalence of Internet addiction among Iranian students was 31.51 percent (95% confidence interval: 26.47–36.55). In addition, meta-regression analysis showed no significant relationship between Internet addiction and year of publication (
Adolescents around the globe are increasingly exposed to online hate speech (OHS). And yet little is known about the varying roles of involvement and the determinants of adolescents' hate speech perpetration. Building on previous research, this study aims to test the cycle of violence hypothesis for OHS and to analyze whether moral disengagement (MD) and empathy moderate the victim-to-perpetrator relationship. The sample consists of 3,560 seventh to ninth graders (52.1 percent girls), recruited from 40 schools across Germany and Switzerland. Self-report questionnaires were administered to assess OHS involvement, MD, and empathy. Multilevel analyses revealed that victims of OHS were more likely to report OHS perpetration. In addition, victims of OHS were more likely to report OHS perpetration when they reported higher levels of MD than those with lower levels of MD. Finally, victims of OHS were less likely to report OHS perpetration when they reported higher levels of empathy than those with lower levels of empathy. The findings extend the cycle of violence hypothesis to OHS and highlight the need to address MD and empathy in hate speech prevention. Implications for future research will be discussed.
Free video-sharing platforms such as YouTube are highly popular among young children but may contain low-quality and highly commercialized content. This study aimed to describe the prevalence, duration, and timing of objectively measured mobile YouTube viewing in preschool-aged children and test hypotheses about associations with child individual differences and contextual factors. We analyzed mobile sampling data from 349 English-speaking children aged 3–4.99 years whose parents completed surveys about child, parent, and household characteristics. We assessed whether the child ever viewed YouTube during the sampling week and calculated average daily duration in a subsample of 121 participants with their own mobile devices. We built multivariable logistic regression models to test correlates of mobile YouTube viewership and duration. Children were 3.82 years (
This study was performed to examine whether depressive symptoms (DPs) and low self-control (LSC) traits has modifying effects on the association of time spent on Internet gaming and problematic Internet game use (PIGU). Among 1,535 middle school students, 42.1 percent reported playing ≥1.5 hours of Internet games/day on average, and 10.0 percent were classified as PIGU. Stratified multiple logistic regression analysis showed gameplay of ≥1.5 hours/day led to more PIGU in the non-LSC traits group (higher DP group,
Adolescents' digital technology use is nearly ubiquitous and has been associated with health benefits and risks, including risks of depression. The Adolescents' Digital Technology Interactions and Importance (ADTI) scale provides a novel approach to measuring how adolescents prioritize their technology use. The purpose of this study was to investigate the relationship between adolescents' technology interactions and mental health measures, including depression and mental well-being. This cross-sectional online survey study recruited adolescents aged 12–18 years using Qualtrics panels. Survey measures included the ADTI and assessments of depression and well-being. Analyses included the Kruskal–Wallis test and multivariate logistic regression analyses. The 4,592 participants had a mean age of 15.6 years (
This study used virtual reality to examine how environmental attributes interact with health communication to influence psychiatric help-seeking behavior, using the example of a subway station. We used a 2 × 2 factorial design crossing two noise conditions (high noise [75 dB] or low noise [30 dB]) and two visual clutter conditions (low clutter [a tidy trash can and orderly construction materials] or high clutter [scattered trash and construction materials]). We found that participants in the high (vs. low) visual clutter condition reported lower cognitive capacity levels, and there was a significant correlation between cognitive capacity and message elaboration. However, we found no effects of noise conditions. Serving as a proof-of-concept study to investigate the contexts in which environmental stressors may influence information processing, this study contributes to the field of health communication environmental design research.
Excessive use of technology has become a worldwide problem due to its high prevalence, fast growth rate, and undesirable consequences. However, little is known about underlying psychological mechanisms that maintain excessive use of technology. We investigated the mediating role of self-esteem, novelty seeking, and persistence on the relationship between attachment dimensions and technology addiction among young adults. Data were collected from 727 young adults (females,
