A theoretical model of the influence of peer relationship and environmental sensitivity on adolescent females'mental health and their interactions
Objective From the perspective of adolescent personality and peer environment interactions,this paper explored the influence of the interaction between peer relationships and environmental sensitivity on adolescent females'mental health development,as well as the theoretical model of the interaction.Methods From September to November 2022,a cross-sectional study on the psychological well-being of adolescents was conducted in 120 classes from six secondary schools(grades 7-12)across four urban districts in Xi'an,Shaanxi Province.5,640 students aged 14 to 17 were randomly selected as the study subjects,among which 3,135(55.6%)were female,and were assessed for their mental health problems(depressive-anxious mood,externalizing behavior,suicidal ideation,sleep quality and subjective well-being)were tested,peer relationships and environmental sensitivity were assessed,and the results were statistically analyzed.Results ① Scores of environmental sensitivity,peer relationships,depression,anxiety,sleep quality,suicidal tendencies,and subjective well-being in adolescent girls were significantly higher than those in adolescent boys(t=-7.504,-7.203,5.554,6.128,5.248,12.194 and-2.864,respectively,P<0.05),while the scores of externalizing behaviors of adolescent females were significantly lower than those of adolescent males(t=8.658,P<0.05).② Peer relationships in adolescent girls was negatively correlated with depression,anxiety,sleep quality and suicide tendencies(r=-0.073,-0.081,-0.121 and-0.422,respectively,P<0.01),and positively correlated with ES,externalized behavior and subjective well-being(r=0.087,0.079 and 0.221,respectively,P<0.01).environmental sensitivity in adolescent females was positively correlated with depression,anxiety,sleep quality and externalized behavior(r=0.271,0.219,0.224 and 0.174,respectively,P<0.01),and negatively correlated with suicide tendencies(r=-0.078,P<0.01),but not correlated with subjective well-being(P>0.05).③ The main effects of the psychological problem history were all significant in predicting the subjective well-being,depressive mood and sleep quality in adolescent girls(b=0.221,-0.361 and-0.394,respectively,P<0.01),when predicting subject well-being,depressive symptom,suicidal tendencies,and sleep quality,peer relationships and environmental sensitivity showed significant main effects(peer relationships:b=0.283,-0.086,-0.431 and-0.179,respectively,P<0.01.environmental sensitivity:b=0.041,0.172,0.082 and 0.167,respectively,P<0.01).The interaction of peer relationships and environmental sensitivity were also significant(b=0.072,-0.074,-0.102 and-0.093,respectively,P<0.05).④The interaction effects of peer relationships and ES on subjective well-being and suicidal tendencies in adolescent girls conform to the differential susceptibility model[subjective well-being:proportion of interaction(PoI)=0.680,proportion affected(PA)=0.720;suicidal tendencies:PoI=0.250,PA=0.210].However,the interaction effects of peer relationships and ES on depression and sleep quality in adolescent girls conform to the diathesis-stress model(depression:PoI=0.010,PA=0.008;sleep quality:PoI=0.050,PA=0.030).Conclusion The interaction effects of peer relationships and ES on subjective well-being and suicidal tendencies in adolescent girls support the differential susceptibility model.However,the effects on depression and sleep quality conform to the diathesis-stress model.This suggests that girls with high ES are more likely to be effected by negative peer relationships,leading to more psychological problems,and they are more likely to benefit from the effects of positive peer environments,promoting overall health development.
