Objective To explore the relationship between aggression

perceived social support and self-control among male juvenile offenders.Methods Based on the method of convenience sampling

306 male juvenile offenders from a juvenile offender correctional center in Guizhou Province were surveyed.The Perceived Social Support Scale

12-item Aggression Questionnaire（12-AQ）

and Self-control Scale were used for this survey.The mediation effect of self-control in the relationship between perceived social support and aggression among male juvenile offenders was assessed using latent variable modeling and the Bootstrap analysis.Results Among these juvenile offenders

the scores of Perceived Social Support Scale and Self-control Scale were 44.55±9.26 and 78.12±7.77

respectively.Meanwhile

the overall 12-AQ score was 35.40±7.77

and the scores in its dimensions of physical aggression

verbal aggression

hostility

and anger were 8.19±2.83

9.01±2.25

9.29±2.44

and 8.91±2.84

respectively.The correlation analysis showed that

perceived social support was positively correlated with self-control（P<0.01）;both self-control and perceived social support were negatively correlated with aggression（P<0.01）.The test for mediation effect revealed that

self-control had a partial mediation effect on the relationship between perceived social support and aggression

accounting for 22.7% of the overall effect.Conclusion Among male juvenile offenders

both perceived social support and self-control are important factors influencing aggression;perceived social support not only directly affects aggression

but also has an indirect impact on aggression via the mediation effect of self-control.
