Comparing factors related to college students’ career decision-making self-efficacy in Japan and China
Career decision-making self-efficacy (CDMSE) plays an important role in young people’s identity development and career choices. However, the underlying mechanisms may differ depending on the social context of each country. We examined individual (self-esteem and career preparation behavior) and environmental (support from others and career education) factors related to CDMSE among university students in Japan and China. Data were collected from 1…

Conflict studies have examined the effects of conditions, such as who first owned an object, and strategies employed by children of varying age groups. On the other hand, longitudinal studies on this issue are ra…
Rhabdophis tigrinus (Yamakagashi) Bites in Japan Over the Last 50 Years

Severe envenomation by R. tigrinus (Yamakagashi snake) in Japan and R. subminiatus in Southeast Asia has been reported. The epidemiology of R. tigrinus bites, such as geographical features, the incidence, and changes in the number of bites over time have not been comprehensively examined. Hence…
QOL and sociodemographic factors among first-time parents in Japan
Trajectories of Early Television Contact in Japan
We examined the link between trajectories of television contact time at ages 1–5 and externalizing problems at age 5, using data from a Japanese longitudinal study of media use and child development (N = 1,189). Despite the American Academy of Pediatrics recommendation for no television contact before age 2, growth mixture modeling identified 3 trajectory classes, comprising heavy-start contact (8%, mean contact time at age 0 = 331.44 min/day), c…
