| Objective: To investigate the status quo of post-traumatic stress disorder of parents of preterm infants,analyze the main influencing factors,and elaborate the correlation between the level of post-traumatic stress disorder of parents of preterm infants and their postpartum depression,social support and coping style,so as to provide theoretical basis for clinical medical staff to implement effective intervention measures to reduce post-traumatic stress disorder of parents of preterm infants.Methods: Using convenience sampling method,232 parents of preterm infants who were hospitalized in neonatal intensive care units of 3 tertiary grade A hospitals in Guangxi were selected as subjects.The general Sociodemographic Data Survey,Post-traumatic Stress Disorder Self-rating Scale(PCL-C),Edinburgh Postnatal Depression Scale(EPDS),Perceived Social Support Scale(PSSS),Cognitive Emotion Regulation Questionnaire(CERQ)as a research tool.SPSS23.0 software was used to make statistics and analysis of relevant data.Frequency,percentage,mean and standard deviation were used for statistical description of the data.Independent sample T-test and one-way analysis of variance were used to compare the differences in the occurrence of post-traumatic stress disorder among research objects with different socio-demographic characteristics.Spearman correlation analysis was used to analyze the correlation between postpartum depression,social support,coping style and post-traumatic stress disorder in parents of preterm infants,and multiple linear stepwise regression was used to analyze the influencing factors of post-traumatic stress disorder in parents of preterm infants.Results:(1)The total score of post-traumatic stress disorder of preterm mothers was(41.42±14.32),including the score of re-experience dimension(12.45±4.96),the score of avoidance/numbness dimension(14.94±5.69),and the score of increased alertness dimension(13.97±5.21);The total score of post-traumatic stress disorder was(37.46±16.21),including the score of re-experience dimension(11.45±5.44),the score of avoidance/numbness dimension(13.99±6.07)and the score of increased alertness dimension(12.14±5.61).(2)There were 88 cases of postpartum depression among preterm mothers,with an incidence of37.9%;There were 76 cases of postpartum depression in fathers of preterm infants,with an incidence of 32.8%.(3)The scores of perceived social support of preterm mothers were(60.41±17.69),including friends support(19.83±6.21),family support(21.03±6.42)and other support(19.56 ± 6.21);The scores of preterm fathers’ perceived social support were(60.17±16.44),including friends’ support(19.65±6.07),family support(21.86±6.17)and other support(18.66±6.75).(4)The score of positive coping dimension was(58.50±11.83),and the score of negative coping dimension was(43.45±10.58);The score of positive coping dimension was(52.25±16.08),and the score of negative coping dimension was(46.31±16.25).(5)The results of univariate analysis showed that the post-traumatic stress disorder score of preterm infants had statistical significance in gestational age,birth weight,length of hospital stay,educational level,parenting experience and monthly family income of preterm infants(P < 0.05);There were statistically significant differences in the scores of post-traumatic stress disorder of fathers of preterm infants in gestational age,birth weight,oxygen administration,length of hospital stay,educational level,occupation,parenting experience,planned pregnancy and monthly family income(P < 0.05).(6)Spearman correlation analysis showed that social support(r=-0.425,P < 0.01)and positive coping(r=-0.447,P < 0.01)of preterm mothers were negatively correlated with PTSD;Postpartum depression(r=0.461,P < 0.01)and negative coping(r=0.447,P < 0.01)were positively correlated with PTSD in mothers of preterm infants.Social support(r=-0.306,P < 0.01)and positive coping(r=-0.519,P < 0.01)were negatively correlated with PTSD in preterm fathers;Postpartum depression(r=0.471,P < 0.01)and negative coping(r=0.683,P < 0.01)were positively correlated with PTSD in fathers of preterm infants.(7)Multiple linear regression analysis showed that five variables,including positive coping,monthly family income,postpartum depression,negative coping and social support,entered the regression equation of mothers,and jointly explained 51.2% of the variation of post-traumatic stress disorder in mothers of preterm infants.Eight variables,including negative coping,monthly family income,positive coping,birth weight,postpartum depression,social support,education and occupation,entered the regression equation of fathers,and together explained 76.5% of the variation of post-traumatic stress disorder in fathers of preterm infants.Conclusion:(1)The incidence of post-traumatic stress disorder in parents of preterm infants was at a medium to high level,mainly reflected in two dimensions:avoidance/numbness and increased alertness;Their social support and active coping ability are at medium level.Postpartum depression and negative coping were at a high level.(2)Post-traumatic stress disorder of parents of preterm infants is correlated with postpartum depression,social support and coping style,that is,the higher the level of social support and positive coping ability,the lower the incidence of post-traumatic stress disorder,which is conducive to the mental health of parents;The higher the level of postpartum depression and negative coping,the higher the incidence of post-traumatic stress disorder,which is not conducive to the establishment of a good parent-child relationship and affects the healthy growth of premature infants.(3)Monthly Family income,postpartum depression,social support and coping style were the main factors affecting the occurrence of post-traumatic stress disorder in mothers of preterm infants;Birth weight,education level,occupation,monthly family income,postpartum depression,social support and coping style are the main factors affecting the occurrence of post-traumatic stress disorder in fathers of preterm infants. |
