From sweeteners to cell phones—Cancer myths and beliefs among journalism undergraduates
2019
OBJECTIVE The media are an important source of health information that can help people make their own medical decisions. However, medical news can also transmit biases produced by different factors, such as the previously held beliefs of journalists. This study identifies which cancer myths are more popular among future journalists and whether their beliefs are related to their chosen source of health information. METHODS A survey was conducted among journalism undergraduates (N = 249) to determine which cancer myths existed and how widespread they were. The survey included a list with different sources of health information and eight questions regarding cancer-related myths. RESULTS The mo…
The potential role of subjective wellbeing and gender in the relationship between bullying or cyberbullying and suicidal ideation
2018
Abstract Bullying and cyberbullying are common problems all over the world. One of their consequences can be suicidal ideation. A better understanding of the mechanisms that link them to suicidal ideation is needed in order to develop effective prevention and intervention initiatives. Subjective wellbeing is a potential mechanism that has not been studied within this framework. The present study examined whether subjective wellbeing could serve as a mediator or moderator of the relationship between bullying or cyberbullying and suicidal ideation, and whether these relationships were moderated by gender. Participants were 1664 students aged 14–19 (M = 16.12; SD = 1.36), 53% female, from 34 s…
Personal exposure to radio-frequency electromagnetic fields in Europe: Is there a generation gap?
2018
Background: Exposure to radiofrequency electromagnetic fields (RF-EMF) from mobile communication technologies is changing rapidly. To characterize sources and associated variability, we studied the differences and correlations in exposure patterns between children aged 8 to 18 and their parents, over the course of the day, by age, by activity pattern, and for different metrics of exposure. Methods: Using portable RF-EMF measurement devices, we collected simultaneous real-time personal measurements of RF-EMF over 24 to 72 h in 294 parent-child pairs from Denmark, the Netherlands, Slovenia, Switzerland, and Spain. The devices measured the power flux density (mW/m(2)) in 16 different frequency…
Measurement Invariance of the Short Version of the Problematic Mobile Phone Use Questionnaire (PMPUQ-SV) across Eight Languages
2018
The prevalence of mobile phone use across the world has increased greatly over the past two decades. Problematic Mobile Phone Use (PMPU) has been studied in relation to public health and comprises various behaviours, including dangerous, prohibited, and dependent use. These types of problematic mobile phone behaviours are typically assessed with the short version of the Problematic Mobile Phone Use Questionnaire (PMPUQ–SV). However, to date, no study has ever examined the degree to which the PMPU scale assesses the same construct across different languages. The aims of the present study were to (i) determine an optimal factor structure for the PMPUQ–SV among university populations using eig…
Fear of Missing Out as a Predictor of Problematic Social Media Use and Phubbing Behavior among Flemish Adolescents
2018
Fear-of-missing-out (FOMO) refers to feelings of anxiety that arise from the realization that you may be missing out on rewarding experiences that others are having. FOMO can be identified as an intra-personal trait that drives people to stay up to date of what other people are doing, among others on social media platforms. Drawing from the findings of a large-scale survey study among 2663 Flemish teenagers, this study explores the relationships between FOMO, social media use, problematic social media use (PSMU) and phubbing behavior. In line with our expectations, FOMO was a positive predictor of both how frequently teenagers use several social media platforms and of how many platforms the…
Brief report: Association between socio-demographic factors, screen media usage and physical activity by type of day in Spanish adolescents.
2010
This study examined the relationship between socio-demographic factors, screen media time usage, and light, moderate and vigorous activities on weekdays and weekends. Cross-sectional data was collected from 323 Spanish adolescents (mean age 13.59 years) who completed an interview administered recall questionnaire. Structural equation models indicated that male and younger adolescents spent more time on vigorous activities at the weekend, while females and older adolescents showed a greater involvement in light activities both on weekdays and weekends. State school students reported engaging in light and vigorous activities for longer periods than private school students on weekends. TV view…
No effects of mobile phone use on cortical auditory change-detection in children: an ERP study
2010
We investigated the effect of mobile phone use on the auditory sensory memory in children. Auditory event-related potentials (ERPs), P1, N2, mismatch negativity (MMN), and P3a, were recorded from 17 children, aged 11–12 years, in the recently developed multi-feature paradigm. This paradigm allows one to determine the neural change-detection profile consisting of several different types of acoustic changes. During the recording, an ordinary GSM (Global System for Mobile Communications) mobile phone emitting 902 MHz (pulsed at 217 Hz) electromagnetic field (EMF) was placed on the ear, over the left or right temporal area (SAR1g = 1.14 W/kg, SAR10g = 0.82 W/kg, peak value = 1.21 W/kg). The EMF…
Validation of short term recall of mobile phone use for the Interphone study
2006
Aim: To validate short term recall of mobile phone use within Interphone, an international collaborative case control study of tumours of the brain, acoustic nerve, and salivary glands related to mobile telephone use. Methods: Mobile phone use of 672 volunteers in 11 countries was recorded by operators or through the use of software modified phones, and compared to use recalled six months later using the Interphone study questionnaire. Agreement between recalled and actual phone use was analysed using both categorical and continuous measures of number and duration of phone calls. Results: Correlations between recalled and actual phone use were moderate to high (ranging from 0.5 to 0.8 acros…
Mobile phone use and exposures in children.
2005
The main difference concerning the use of mobile phones (MPs) between today's children and adults is the longer lifetime exposure of children when they grow older, due to starting to use MPs at an early age. Additionally, recent trends lead to a higher frequency of use among children, including higher popularity of MPs and features specifically designed to attract children. The prevalence of MP users is already very high and reaches >90% among adolescents in some countries. In a German study, 6% of 9-10 years old children used a MP for making calls daily; 35% owned their own MP. For children, MPs are dominant sources of radio wave exposures and relevant sources of extremely low frequency ma…
EmoTIC: Impact of a game-based social-emotional programme on adolescents
2021
[EN] Introduction Technologies provide a brilliant opportunity to promote social-emotional competences, well-being and adjustment in adolescence. Game-based programmes and serious games are digital tools that pursue an educational goal in an attractive environment for adolescents. The purpose of this study was therefore to determine the effectiveness of emoTIC, a game-based social-emotional programme designed according to Mayer, Caruso, and Salovey's model of emotional intelligence. Materials and methods The participants were 119 adolescents between 11 and 15 years, randomly assigned to the experimental group and the control group. The adolescents completed questionnaires to assess their em…
