The purpose of this paper is to examine the mediating effect of cyber-victimization (CV) and the moderating effect of academic stress (AS) in the link between smartphone addiction (SPA) and psychological distress (PD) among a sample of Vietnamese college students.

A total of 423 college students participated in this study. Measures of SPA, CV, AS and PD were used for data collection. Using PROCESS macro software (Model 4 and Model 1) and the bootstrapping method, the author performed a mediation analysis and a moderation analysis.

Results indicated a significant mediating effect of CV in the link between SPA and PD. Moreover, this relationship was moderated by AS.

The findings could serve as a guide for future research and mental health professionals.

Online self-disclosure and online social support have important effects on well-being. The purpose of this study was to examine the indirect effect of online social support through social networking sites (SNSs) in the link between online self-disclosure through SNSs and well-being among Vietnamese adolescents.

Using a convenience sample of 980 Vietnamese adolescents (332 men, 648 women) and three scales (the Subjective Happiness Scale, the Self-Disclosure Scale and the Two-Way Social Support Scale), this study investigated whether online self-disclosure has a direct and indirect effects on well-being when mediated by online social support.

Mediation analysis showed that online social support partially mediated the link between online self-disclosure and well-being among Vietnamese adolescents, β = 0.008, standard error = 0.004, confidence interval = [0.001, 0.017].

This study provides an important practical basis for developing interventions to improve the well-being of adolescents who use SNSs. This finding indicated that adolescents’ well-being can be enhanced through online self-disclosure and online social support.

This study aims to investigate the conditional indirect effect of academic self-efficacy in the interplay between academic motivation and academic satisfaction through academic engagement among university students.

A cross-sectional study was performed on 1,638 Vietnamese university students (31.9% males and 68.1% females) aged 16 to 36 (Mean = 20.06, SD = 1.428). The participants filled out a questionnaire with the Vietnam versions of the General Self-Efficacy Scale, Academic Motivation Scale, Academic Life Satisfaction Scale and Academic Engagement Scale. Model 4 and Model 7 in the PROCESS macro were used for the mediation analysis and the moderated mediation analysis.

Results showed that the indirect effect of academic engagement on the academic motivation-academic satisfaction link was significant. Furthermore, academic self-efficacy moderated this indirect effect. The indirect effect was stronger among students with high academic self-efficacy and weaker among students with low academic self-efficacy.

This study’s findings contribute to educational research on academic satisfaction and can be used by institutions of higher education and educators to enhance academic satisfaction among university students.

This study aimed to investigate whether optimism buffers an indirect relationship between COVID stress and depressive symptoms via poor sleep quality among Vietnamese high school students.

Six hundred and eighty-five participants completed the Coronavirus Stress Measure, the Life Orientation Test-Revised, the Pittsburgh Sleep Quality Index and the Depression, Anxiety and Stress Scales. Process Macro 3.5 for SPSS (Model 4 and Model 14) was used to analyze the mediating effect and moderated mediation effect.

The results indicated that COVID stress was associated with an increase in depressive symptoms via the indirect pathway of poor sleep quality. Furthermore, optimism moderated the indirect relationship between COVID stress and depressive symptoms through poor sleep quality among Vietnamese students.

The study's findings may serve as a basis for the development of depression prevention interventions for students with high COVID stress in the COVID-19 pandemic.

“The world needs science, science needs women” is the message given by UNESCO in the program for the development of women in science” (UNESCO, 2017). In Vietnam, women’s participation and achievements in scientific research is considered a great and important resource for industrialization and modernization. Even so, are there gender differences in scientific achievement in the social science research institutes in Vietnam? What factors influence the scientific achievement of female social researchers? The answers will be based on data from a 2017 survey with a sample of 756 researchers, of which 77.6% were female. The survey was conducted by the Vietnam Academy of Social Sciences, a leading, ministry-level national center for the social sciences in Vietnam. This chapter analyzed the scientific achievements of researchers through their position as principal investigators of research projects and their publications, and factors that may impact this. Bivariate and multivariate analyses of factors that may affect the scientific achievement of researchers found that gender differences in academic achievement in the social sciences in Vietnam was still prevalent. Female researchers’ scientific achievements were lower than those of their male counterparts. The contribution to science of Vietnamese female researchers was limited by many different factors; the most important were the academic rank of the researchers and gender stereotype that considered housework the responsibility of women.
