The beneficial effects of learners interacting in online programmes have been widely reported. Indeed, online discussion is argued to promote studentcentred learning. It is therefore reasonable to suggest that the benefits of online discussion should translate into improved student performance. The current study examined the frequency of online interaction of 122 undergraduates and compared this with their grades at the end of the year. The findings revealed that greater online interaction did not lead to significantly higher performance for students achieving passing grades; however, students who failed in their courses tended to interact less frequently. Other factors that may be salient in online interactions are discussed.
A number of authors have emphasized the importance of self-esteem in the aetiology of the eating disorders anorexia nervosa and bulimia nervosa. Evidence for such theorizing, however, mainly derives from clinical observations on people being treated for eating disorders. This study is the first prospective study to investigate the role of self-esteem in aetiology prior to the onset of an eating disorder. Self-esteem was measured in 594 schoolgirls aged 11-12 using the Rosenberg Self-Esteem Scale (Rosenberg, 1965). Almost 400 of these girls were successfully followed up at age 15-16 and they completed a questionnaire examining eating and other psychological problems. Results showed that girls with low self-esteem at age 11-12 were at significantly greater risk of developing the more severe signs of eating disorders, as well as other psychological problems, by the age of 15-16. It is argued that more research is needed to replicate and extend these findings. The results also give weight to the case for examining the potential role of self-esteem enhancement in the prevention of eating disorders.
Objective: This study aimed to investigate the extent of eating problems and their association with self-esteem in girls aged 15-16. Method: Six hundred and nine schoolgirls aged 15-16 completed a questionnaire examining eating behavior, self-esteem, and general psychological well-being. A subsample of 31 girls was subsequently interviewed in terms of eating behavior and self-esteem. Results: The questionnaire findings revealed that 56% of girls felt too fat and had used some form of weight control strategy. In addition, 32% scored above the Hospital Anxiety and Depression Scale (HADS) threshold for anxiety and 43% reached the Rosenberg Self-Esteem Scale criterion for low self-esteem. Interviews confirmed that those showing abnormal eating behavior in the questionnaires did indeed show greater eating pathology as well as lower self-esteem. Interviews also revealed that those with high levels of eating concern showed greater levels of global self-dissatisfaction and higher dissatisfaction with their physical appearance and family relationships. Discussion: The results suggest that preventative interventions targeted at girls with low self-esteem may be appropriate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
