Student-athletes may have high stress, and the level of their subjective well-being could be low due to the dual role of being a student and an athlete. In the field of sport psychology, social support has received focal attention to identifying its impact on individuals’ subjective well-being. However, there is a lack of research that focuses on teammate support and subjective well-being. Thus, this study examined how the perception of teammate support influences subjective well-being through positive emotions based on the environmental psychology model and the broaden-and-build theory of positive emotions. This study collected 313 responses from university student-athletes in Singapore and conducted a confirmatory factor analysis and structural equation modeling analysis. Results showed that perceived teammate support had a positive influence on subjective well-being through positive emotion. Also, there was a direct effect of perceived teammate support on subjective well-being. The results support the critical role of perceived teammate support in enhancing the student-athletes’ subjective well-being. The findings of this study are beneficial for coaches and student-leaders to design strategies to improve the subjective well-being of student-athletes.

We investigated the mediating role of need for control in the relationship between narcissism and perspective taking. A sample of 178 college students completed measures of narcissism, empathy (including empathic concern and perspective taking), need for control, and self-esteem. Results show that narcissism had a direct negative effect on perspective taking. Need for control partially mediated the relationship between narcissism and perspective taking when controlling for self-esteem. That is, participants with higher scores for narcissistic personality tended to be less motivated to take others' perspectives. This tendency was strengthened because narcissists are more driven by power. The findings show that identification of narcissists' need for control and application of therapy or a program to improve their perspective-taking motivation and empathetic communication, will improve their psychological functioning and social behavior.

Excessive focus on appearance or lookism requires social attention as it can have negative consequences on individuals’ psychological and mental states related to health and sustainable social practice. As part of a healthy and sustainable social practice, this study tests the mechanism of enhancing appearance-related health campaign’s effectiveness through the O1-S-O2-R framework. Participants were 220 Korean college students with being 141 male and 78 female and they completed an on-line survey. The result of SEM analyses confirmed the O1-S-O2-R model. As the result of hypotheses testing, health campaign contents suggesting anti-lookism and diverse beauty standards have attracted the attention of people whose parents conversed using relatively less healthy-appearance talk when growing up and who had higher self-objectification scores with body surveillance and body shame. Interpersonal conversations and thoughts on the media content played a mediating role in the model, while health campaigns had a higher persuasive effect on campaign evaluation and the behavior intention of spreading the campaign’s content. Implications of the findings were discussed regarding health campaign designers and individuals, including parents, in education settings.
