School victimization issues remain largely unresolved due to over-reliance on unidimensional conceptions of victimization and data from a few developed OECD countries. Thus, support for cross-national generalizability over multiple victimization components (relational, verbal, and physical) is weak. Our substantive-methodological synergy tests the…

Young children born preterm may be more affected by environmental influences than their full-term peers. Few studies have investigated whether such effects exist for older children and young adolescents. With participants aged 9 and 13 years, we examine whether children born preterm could be differentially affected by the quality of their…

Students with language-based learning disabilities (LBLD) can face elevated socio-emotional well-being challenges in addition to literacy challenges.

School personnel often take on ancillary responsibilities that extend beyond their role as educational professionals, including supporting students who have parents suffering from substance use disorders (SUDs). Our objectives were to use the experience of these school personnel to better understand how healthcare professionals can support school…

American adolescents consume more sugar-sweetened beverages (SSBs) than any other age group. Sports and energy drinks consumption among adolescents is higher than other SSBs. For sports drinks, there is uncertainty about their "healthiness" and also beliefs that these drinks may provide health benefits such as hydration, enhanced…
