Abstract:
Objective To explore the mediating effects of neuropeptide S receptor 1 and negative coping in chronic stress induced emotional responses. Methods A survey of 366 local residents who were chosen from County of Nandan in Guangxi Province by stratified random sampling method. Questionnaires of the life events scale (LES),the simplified symptom checklist and the Simplified Coping Style Questionnaire (SCSQ) were used. The level of NPSR1 was measured by Elisa. Data was analyzed by SPSS 21 and AMOS 21 statistical software for statistical analysis. Results The level of chronic psychological stress was (25. 24± 29. 26) and score of negative coping was(14. 84±4. 35). Somatic factor,anxiety factor,depressive factor and hostile factor were (1. 58±0. 58),(1. 43±0. 56),(1. 44±0. 55),(1. 23±0. 37). The total score of life e-vents was positively correlated with negative coping,somatic factor score,anxiety factor score,depression fac-tor score(r=0. 23-0. 46,P<0. 05),while negatively correlated with the expression level of detection of NPSR1 in plasma(r=-0. 26,P<0. 05). NPSR1 level was negatively correlated with body factor score,anxiety factor score,depression factor score and hostility factor score(r=-0. 18--0. 61,P<0. 05). Negative coping was positively correlated with body factor score,anxiety factor score,depression factor score and hostility fac-tor score(r=0. 12- 0. 27,P<0. 05). Both neuropeptide S receptor 1 and negative response had significant me- diating effects on emotional responses induced by chronic psychological stress (P<0. 05),and the effect val-ues were -0. 08 and 0. 05,respectively. According to the Bootstrapping method,the results of the mediation model showed that Bias-Corrected of 95% CI of the total standardization effect,the indirect standardization effect,the direct standardization effect were not including 0. Conclusion NPSR1 and negative coping plays a dual mediating effect on stress induced emotional responses.
