Background: School bullying is a widespread phenomenon affecting a significant proportion of adolescents worldwide, yet the relationship between school bullying and loneliness has received little attention. The aim is to understand the relationship between adolescents experiencing school bullying and loneliness, and to explore the role of social connectedness and parental support in this relationship.
Methods: This study used cluster sampling to select 1,277 students from grades 7 to 12 in four middle schools across two cities in Sichuan Province. Data were collected via questionnaires and analysis was carried out using descriptive statistics, chain mediation model tests, and moderation model tests.
Results: The results showed that: (1) Bullying was significantly positively correlated with adolescent loneliness (r = 0.55, P < 0.001); (2) Social connectednessplayed a mediating role between bullying and adolescent loneliness (effect size of 51.57%); (3) After controlling for gender, age, and household registration type, parental support moderated the relationship between bullying and loneliness among adolescents (β = -0.05, p < 0.01). Moreover, as the level of parental support increased, the positive predictive effect of bullying on loneliness weakened significantly, although this moderating effect was not significant among "non-left-behind children."
Conclusion: The study confirmed the relationship between school bullying and loneliness and revealed the internal logical relationship between social connectedness, parental support, loneliness, and school bullying, providing agreat significance for preventing the negative effects of school bullying on left-behind children.
