Coping Style Predicts Sense Of Security And Mediates The Relationship Between Autistic Traits And Social Anxiety: Moderation By A Polymorphism Of The Fkbp5 Gene

The mechanism underlying the relationship between autistic traits and social anxiety still remains unknown. It is therefore necessary to investigate potential psychological and biological mechanisms. A total of 2695 college students were samples for this research during 2017-2018. The assessed variables included demographic characteristics and measures of autistic traits, sense of security, coping styles, and social anxiety. Blood samples were collected from which DNA was extracted. Regression analysis indicated that autistic traits and negative coping were positively associated with social anxiety; furthermore, positive coping, interpersonal security, and sense of control were negatively associated with social anxiety. Further analyses demonstrated that the rela-tionship between autistic traits and social anxiety was mediated by coping styles (both positive coping and negative coping) and sense of security (both interpersonal security and sense of control), and coping style pre-dicted the sense of security. The FK506 binding protein 5 (FKBP5) gene rs3800373 moderated the association between autistic traits and social anxiety. The present study is the first to demonstrate that both coping style and sense of security play an intermediate role between autistic traits and social anxiety in a sample of Chinese college students; moreover, the FKBP5 gene moderates this association between autistic traits and social anxiety.
