The mediating effect of cognitive appraisal on the relationship between sleep habits and the stress response among Japanese female college students.

Background: Undergraduate students tend to develop "evening-type" sleep patterns. Recent research has reported that evening-type and irregular sleep habits are related to physical and mental stress responses, particularly in female students. Although the connection between sleep habits and the stress response has been well documented, the mechanism behind this relationship is currently unknown.

Thin-ideal internalization and body dissatisfaction in Sri Lankan adolescents.

In this study, a survey of Sri Lankan adolescents explored relationships between thin-ideal internalization and body dissatisfaction-issues that have received greater research attention in East Asia and the West. Girls scored lower in thin-ideal internalization and awareness and higher in self-esteem compared to boys; however, unlike in previous studies, body dissatisfaction did not differ significantly by gender. Hierarchical linear multiple regression analyses revealed that self-esteem moderated the relationship between thin-ideal internalization and body dissatisfaction among girls, but this was not observed for boys.
