| Since December 2019,the outbreak of the Corona virus disease 2019(COVID-19)has spread rapidly across the country and spread globally.The outbreak of the epidemic not only threatens people’s lives,but also caused people’s anxiety and panic due to its rapid spread and lethality.Among many people,migrants may face the double risk of becoming a“victim+source of infection”.Their mental health is worthy of attention.At the same time,after individuals experience a traumatic event,the discussion of the relationship between post-traumatic stress symptoms,anxiety and depression is also a relatively new topic in the field of trauma psychology.Based on the investigation of the mental health of the migrants during the epidemic,this study explored the predictive relationship among post-traumatic stress symptoms,anxiety symptoms,and depression symptoms from the perspective of longitudinal tracking.This study can be divided into the following two studies:study one uses an online questionnaire to investigate the mental health and its characteristics of 529 migrants during the epidemic;study two focuses on post-traumatic stress symptoms(PTSS),anxiety,and depression of the migrants during the epidemic using the cross-lag method to explore the predictive relationship between the three variables at different time points(Mid-to-early March 2020,T1;End of March 2020,T2;October 2020,T3).The results showed that:(1)The epidemic did not have a significant impact on the mental health of the migrants.The migrants had the lowest levels of post-traumatic stress,anxiety,and depression at T2;the migrants had the lowest levels of post-traumatic stress,anxiety,and depression at T3.The level of depression is the highest;the levels of post-traumatic stress symptoms,anxiety,and depression of the migrants from T1 to T3 showed a trend of first decline and then rise,and at three time points,post-traumatic stress disorder,moderate-severe anxiety,and moderate-severe depression the detection rate of all presents a low level.(2)During the epidemic period(T1),for the migrants with different education levels,the PTSS scores were significantly different[F(4,524)=2.402,p<0.05],and the depression scores were significantly different[F(4,524)=3.280,p<0.05];during the normalization period of epidemic prevention and control(T3),for the migrants with different education levels,the PTSS scores were significantly different[F(4,524)=2.963,p<0.05],and the anxiety scores were significantly different[F(4,524)=4.432,p<0.01],and the scores of depression are significantly different[F(4,524)=3.280,p<0.001].(3)The fitting index of the cross-lag model of the relationship between the migrants’s post-traumatic stress symptoms,anxiety and depression is good:χ~2/df=4.502,CFI=0.935,TLI=0.914,IFI=0.936,RMSEA=0.081.PTSS at T1 time point can significantly positively predict anxiety at T2 time point(β=0.10,p<0.05),and then significantly positively predict depression at T3 time point(β=0.16,p<0.05);T1 time anxiety at T2 can significantly positively predict depression at T2(β=0.23,p<0.001),and depression at T2 can significantly positively predict anxiety at T3(β=0.16,p<0.01);Depressive symptoms at T1 time point can significantly positively predict anxiety at T2 time point(β=0.20,p<0.001),and then significantly positively predict symptoms at T3 time point(β=0.16,p<0.05).The main conclusions are as follows:(1)The epidemic did not have a serious negative impact on the mental health of the migrants in Jiangsu Province.(2)During the epidemic,the mental health of the migrants with higher education level is relatively better.(3)The PTSS of the migrants during the epidemic period can predict depression by predicting anxiety;the depression of the migrants can predict anxiety by predicting PTSS,and there is a lagging relationship between the three variables(3)The anxiety and depression of the migrants during the epidemic period can predict each other.In this study,the migrants in Jiangsu Province were used as subjects.Based on the investigation of the mental health of migrant workers during the epidemic period,the tracking perspective was used to investigate the relationship between symptoms of post-traumatic stress disorder,anxiety,and depression during the epidemic period.Later,it provided theoretical support for the psychological intervention of the migrants affected by the epidemic,making the psychological service work more targeted. |
