The Effect of Left-Behind Experience and Self-Esteem on Aggressive Behavior in Young Adults in China : A Cross-Sectional Study.

There is little investigation on the independent effects of left-behind experience (LBE) on self-esteem and aggressive behavior in Chinese young adult populations, or the interaction effects of LBE and self-esteem on aggressive behavior. Thus, a school-based health survey was conducted in Anhui province in China in 2017. A total of 4,154 college students completed standard questionnaires which contain details of left-behind-related characters, self-esteem, aggressive behavior, and sociodemographic profile. Of included students, 55.3% were those with LBE (LBEs). Compared to students without left-behind experiences (NLBEs), LBEs had significantly increased scores of aggressive behavior and decreased score of self-esteem. The increased aggression in LBEs was highly related to longer left-behind duration, younger age of left-behind for the first time, and decreased self-esteem. On the other side, the aggressive behavior was demonstrated negatively correlated with self-esteem in both LBEs and NLBEs. There was an interaction effect of left-behind duration and self-esteem on physical aggression and of frequency of contacting with parents and self-esteem on verbal aggression. Besides, the interaction of primary caregiver and self-esteem on hostility and aggression toward self were also observed, respectively. Our results indicated LBEs and low self-esteem are associated with increased risk of aggressive behavior in Chinese young adults. The increased aggressive behavior in LBEs were highly related to longer left-behind duration, younger age of left-behind for the first time and decreased self-esteem. In those LBEs with some certain left-behind-related characters, aggressive behavior decreased more prominently with the increase of self-esteem. Strategies to improve self-esteem, particularly among young adults who have certain characters of LBE, should be a significant component of prevention and interventions of aggressive behavior.

The relationship between left-behind experience and obsessive-compulsive symptoms in college students in China: the mediation effect of self-esteem.

The number of left-behind children in China is gradually increasing, and college students with left-behind experience (LBE) have more severe mental health problems. The aim of this study was to evaluate the association of LBE and the obsessive-compulsive (OC) symptoms of college students, explore the mediation role of self-esteem in the relationship between them. A total of 4145 college students were recruited in Anhui province, China. The Chinese Obsessive-Compulsive Inventory-Revised (OCI-R) and Rosenberg Self-Esteem Scale (RSES) were used to measure OC symptoms and self-esteem. Bootstrap program was used to test the mediation effect. The results showed that the detection rate of OC symptoms was 24.1%. Multiple linear regression analyses found that LBE was positively associated with OC symptoms (t = 2.928, p = 0.003). High self-esteem scores in college students were significantly associated with a lower probability of OC symptoms (t = -17.023, p < 0.001). Furthermore, the test of Bootstrap showed that the indirect effect of self-esteem between LBE and OC symptoms was significant for 95% CI (LLCI = 0.3586, ULCL = 0.7264) and the mediation effect was 0.5396. The ratio of the indirect effect to the total effect was 0.408. OC symptoms were common mental health problems among college students. LBE had a positive predictive effect for OC symptomsand self-esteem plays a mediating role between them. Improving self-esteem will be beneficial to prevent and control the OC symptoms of college students.
