Cumulative ecological risk and cyberbullying among college students: a chain mediation model

Introduction

Cyberbullying among college students has been receiving increased research attention. Previous studies have focused primarily on the impact of a single risk factor on cyberbullying among college students. However, individual behavior is influenced by multiple ecosystems simultaneously, including family, school, and peers. To explore the effects of a single risk factor alone is not in line with the reality of everyday life, and the effect of the single risk factor can often be overestimated. Therefore, this study aimed to explore the impact of multiple risk factors, namely cumulative ecological risk, on cyberbullying, while analyzing the mediating roles of belief in a just world and moral disengagement.

Methods

A survey was conducted among 805 college students from two universities in Hebei Province, China, using the cumulative ecological risk questionnaire, the cyberbullying scale, the belief in a just world scale, and the moral disengagement scale.

Results

The results showed that: (a) Cumulative ecological risk was positively correlated with moral disengagement and cyberbullying, and negatively correlated with belief in a just world. Belief in a just world was negatively correlated with moral disengagement and cyberbullying. Moral disengagement was positively correlated with cyberbullying; (b) Belief in a just world partially mediated the relationship between cumulative ecological risk and cyberbullying; (c) Moral disengagement partially mediated the relationship between cumulative ecological risk and cyberbullying; (d) Belief in a just world and moral disengagement played a chain mediating role between cumulative ecological risk and college students' cyberbullying.

Discussion

This study provides valuable insight for the reduction of cyberbullying behavior among college students, and offers suggestions on how to create a more favorable online environment.

The Links Among Cumulative Ecological Risk and Smartphone Addiction, Sleep Quality in Chinese University Freshmen: A Two-Wave Study

Purpose

While previous research has highlighted the influence of family, school, and peer factors on smartphone addiction and sleep quality, the cumulative effects of these risk factors and their underlying causal relationships remain poorly understood. Therefore, based on the cumulative risk model and the bioecological model of human development, this study examined the longitudinal associations between cumulative ecological risk and smartphone addiction and sleep quality.

Methods

A survey was conducted among 653 Chinese university freshmen (mean age 18.56) at two distinct time points, with a 6-month interval. The initial assessment focused on family, school, and peer risk factors, while the subsequent assessment focused on smartphone addiction and sleep quality.

Results

Approximately 63.71% of university freshmen were found to be at risk of exposure. Compared to other risk-exposure groups, the group with no-risk exposure exhibited the lowest scores for smartphone addiction and sleep quality. The relationships between cumulative ecological risk and smartphone addiction and sleep quality displayed a linear pattern and a discernible "gradient effect". Smartphone addiction was identified as a fully mediating factor in the link between cumulative ecological risk and sleep quality, with a mediating effect value of 0.08 (representing 44.44% of the total effect).

Conclusion

University freshmen face various risks associated with their families, schools, and peers. The cumulative ecological risk can, directly and indirectly, impact sleep quality by influencing smartphone addiction. Given the observed "gradient effect" of cumulative ecological risk on smartphone addiction and sleep quality, it is imperative to adopt comprehensive risk prevention strategies to mitigate the impact of each risk factor.

Cumulative ecological risk and nonsuicidal self-injury in adolescents: The mediation of depression and the moderation of impulsiveness

BACKGROUND

This study is based on the biosocial model of nonsuicidal self-injury (NSSI), to explore the effects of cumulative ecological risk on adolescents' NSSI, the mediating effect of depression between cumulative ecological risk and adolescents' NSSI, and the moderating role of impulsiveness in this mediating pathway.

METHODS

A total of 16 508 adolescents, with 7903 males (47.9%), participated in the study and completed the Cumulative Ecological Risk Questionnaire, the Short Form of the Center for Epidemiological Studies Depression Scale, the Impulsiveness assessment, and the Nonsuicidal Self-Injury Scale.

RESULTS

(1) There was a significant positive correlation between cumulative ecological risk, depression, impulsiveness, and NSSI; (2) cumulative ecological risk significantly predicted adolescents' NSSI; (3) depression had a mediating effect between cumulative ecological risk and adolescents' NSSI; and (4) impulsiveness moderated both the effects of cumulative ecological risk on adolescents' depression and NSSI and the effects of depression on NSSI in adolescents.

CONCLUSIONS

Impulsiveness and depression are risk factors for adolescent NSSI and play a crucial role between cumulative ecological risk and NSSI in adolescents.

Cumulative Ecological Risk and Academic Burnout in Chinese College Students: A Moderated Mediation Model

This study explored the relationship between cumulative ecological risk exposure and academic burnout among Chinese college students and the mediating and moderating effects of neuroticism and gender, respectively. A total of 580 college students were selected as participants. They completed a battery of questionnaires that measured cumulative ecological risk, neuroticism, and academic burnout. The results showed that: (1) cumulative ecological risk was positively related to neuroticism and academic burnout; (2) cumulative ecological risk positively predicted academic burnout; (3) neuroticism partly mediated the relationship between cumulative ecological risk and academic burnout; and (4) gender moderated the effect of cumulative ecological risk and academic burnout. A high level of cumulative ecological risk had a greater impact on neuroticism among women, compared to men. These findings advance our current knowledge of the specific effects of cumulative ecological risk on academic burnout and the underlying internal mechanisms of this relationship. Furthermore, this study provides a constructive perspective on preventing and reducing academic burnout among college students.

The Mechanism of Cumulative Ecological Risk Affecting College Students' Sense of Social Responsibility: The Double Fugue Effect of Belief in a Just World and Empathy

According to bioecological theory, the development of college students' social responsibility is affected by the cumulative effect of ecological risks. However, research on the impact of cumulative ecological risk on social responsibility and its potential mechanisms are still lacking. Carol Gilligan (1982) proposed that the ethics of care and justice are like two related but independent melodies, which together constitute the whole of moral psychology. However, despite being an important part of moral psychology, social responsibility has rarely been investigated empirically with regards to the psychological mechanisms of justice and caring orientation. Therefore, the current study had 1607 college students complete questionnaires regarding cumulative ecological risk, social responsibility, belief in a just world, and empathy, aiming to explore the impact of cumulative ecological risk on college students' sense of social responsibility and the mediating roles of belief in a just world and empathy. Results showed that: (1) cumulative ecological risk was significantly negatively correlated with college students' sense of social responsibility, belief in a just world, and empathy, whereas social responsibility, belief in a just world, and empathy were significantly positively correlated; (2) belief in a just world and empathy played mediating roles in the relationship between cumulative ecological risk and social responsibility. The results also showed that the development of college students' sense of social responsibility was affected by the cumulative ecological risk from various directions; this influence was also seen to play a role in the motivation system of social responsibility through the ethics of care with empathy as the important part, as well as through the ethics of justice. The results suggest that we should reduce the ecological risks at their source, and improve and consolidate students' social support systems; moreover, we should not only enhance college students' sense of mission and responsibility to consciously maintain social justice order, but also adopt empathy training as a part of the curriculum to improve students' empathy at the individual level.

Cumulative Ecological Risk and Problem Behaviors Among Adolescents in Secondary Vocational Schools: The Mediating Roles of Core Self-Evaluation and Basic Psychological Need Satisfaction

Based on the Cumulative Risk Model, a single risk factor cannot play a decisive role, but the cumulative ecological risks may have complex superposition effects on adolescents' problem behaviors. However, although many studies have investigated the specific influences of single external risk factors on problem behaviors, the effect of cumulative ecological risk on problem behaviors and especially the underlying mechanisms therein have been under-investigated. Therefore, this study aimed to explore the effect of cumulative ecological risk on adolescents' problem behaviors, and the mediating effects of core self-evaluation and basic psychological needs satisfaction therein. To achieve this, 1,080 adolescents in secondary vocational schools were surveyed with the questionnaires of cumulative ecological risk, basic psychological need satisfaction, core self-evaluation, externalizing and internalizing problem behaviors. Results showed that: (a) cumulative ecological risk was positively related with both internalizing problem behavior and externalizing problem behavior; (b) core self-evaluation and basic psychological need satisfaction not only respectively but also sequentially mediated the relationship between cumulative ecological risk and two sorts of problem behaviors. These results provide some pivotal implications for the precaution and intervention of the adolescent problem behaviors.
