Frank J. Elgar, PhD Associate Professor of Psychiatry Canada Research Chair in Social Inequalities in Child Health Institute for Health and Social Policy, McGill University Montreal, Quebec, CanadaMedicalResearch.com Interview with: Frank J. Elgar, PhD Associate Professor of Psychiatry Canada Research Chair in Social Inequalities in Child Health Institute for Health and Social Policy, McGill University Montreal, Quebec, Canada Medical Research: What are the main findings of the study? Dr. Elgar: Our study addressed two questions. The first was whether cyberbullying has unique links to adolescent mental health, or is an extension of traditional (face-to-face) bullying. We measured various forms of bullying and found that cyberbullying does indeed have a unique impact on mental health. Our second question about protective factors in the home environment.  We examined the frequency of family dinners as potential a moderating factor - understanding, of course, that dinners are a proxy of various family characteristics that benefit adolescents, such as communication, support, and parental monitoring. We found that teens who were targeted by cyberbullying but had ate dinner with their families more often had significantly better mental health outcomes as a result. (more…)

Mitch van Geel, PhD Institute of Education and Child Studies, Leiden University Leiden, the NetherlandsMedicalResearch.com Interview with: Mitch van Geel, PhD Institute of Education and Child Studies, Leiden University Leiden, the Netherlands MedicalResearch.com: What are the main findings of the study? Dr.van Geel: We performed a meta-analysis, which is a way to statistically summarize effect sizes from earlier studies. Individual studies often provide varying effect sizes, which makes it difficult to judge whether and how strong variables are related. Furthermore, study characteristics (sampling methods, response rates, controlling for certain confounders) might influence study results. By using a meta-analysis it can be analyzed to what extent study characteristics are related to results; if a particular result only tends to be established in studies with certain designs (for example a convenience sample), we might wonder whether such an effect really exists; but if we find that a particular outcome is unrelated to study characteristics or found in studies with relatively stronger designs, we might feel more certain in concluding that a relation between variables (bullying-suicide thoughts or attempts) exists. By using a meta-analysis we established a significant relation between bullying and thoughts about suicide, and bullying and suicide attempts, and we found that these results were unrelated to study characteristics.
