ABSTRACT
Social network plays an important role in the prevention and recovery of posttraumatic stress disorder (PTSD).Researches of egocentric network focus on the protective effect of large size and high diversity of social support network on PTSD,while researches about global network focus on social integration. Egocentric network and global network reduce the negative emotional reactions or physiologic and behavioral responses to stress in different ways,the former buffers stress response through social support,the latter em-phasizes the importance of interpersonal emotional contagion and social resource change. Future studies are required to explore the relationship between social structure or the social network changes and PTSD by using longitudinal method,in the meantime intervention studies about improving social network to reduce PTSD are also worth doing.
ABSTRACT
Objective:To test the validity and reliability of the University of California at Los Angeles Posttraumatic Stress Disorder Reaction Index for DSM-Ⅳ (Revision 1,Children version) (UCLA PTSD-RI) in Chinese Children after flood.Methods:On the principle of convenient sampling,the students were chosen from 6 schools in Liaoning Province where was hit by flood.Totally 1593 students [aged 8-16 years,average (11 ± 2) years of age]completed the UCLA PTSD-RI.They were randomly divided into two groups for exploratory factor analysis (n =796) and confirmatory factor analysis (n =797) respectively.The 21-item Depression Anxiety Stress Scale(DASS-21) were used to evaluate the criterion validity.Results:The result of exploratory factor analysis indicated UCLA PTSD-RI consisted of 3 factors,accounting for 50％ of the total variance.The confirmatory factor analysis identified that a three-factor model fit well (x2/df=3.87,GFI =0.93,RFI =0.96,CFI =097,NNFI =0.97,IFI =0.97,RM-SEA =0.06).The scores of UCLA PTSD-RI subscales were positively correlated with the scores of DASS-21 subscales (r =0.52-0.70,Ps ＜ 0.001).The Cronbach's a coefficient and the split-half reliability coefficient of UCLA PTSD-RI were 0.90 and 0.87,respectively.Conclusion:The Chinese Version of the UCLA PTSD Reaction Index for DSM-Ⅳ (Revision 1,Children version) could be an effective instrument for assessing and diagnosing PTSD of Chinese children after disasters.
ABSTRACT
Objectives:To investigate the prevalence of depressive emotion and related factors among rural elderly living in urban-rural fringe zones and traditional villages.Methods:Totally 1135 rural elderly were surveyed in Fuding,Fujian Province.The 10-item CES-D Scale was adopted to assess depressive emotion (score 10 or higher as having depression problem),and a self-made questionnaire was used to investigate other relevant demographical information.Results:Rural elderly lived in traditional villages had significantly higher ratio of depression than the elderly lived in urban-rural fringe zones (49.6％ vs.30.3％,P ＜0.001).Logistic regression analysis showed that the ratio of depression in elderly of traditional villages was 1.40 times that of urban-rural fringe zone after control ling other factors.Other important factors (P ＜ 0.001) related to depression were poorer self-rated health (OR =7.52),financial strain (OR =4.41),negative life event (OR =2.91),and living alone (OR =2.72) in elderly of urban-rural fringe zone,but only financial strain (OR =8.52) in elderly of traditional villages.Conclusion:Depression is more prevalently identified among rural elderly living in traditional villages,and urbanization could effectively reduce depression in rural elderly.Public policies should improve the financial and medical security,social support and so on to promote the emotional well-being among rural elderly during urbanization.
ABSTRACT
Objective:To explore the prevalence of posttraumatic stress symptoms among preschool children and its related factors after the Ludian earthquake.Methods:A total of 62 children's guardians were visited.They were interviewed with the Posttraumatic Stress Disorder Semi-Structured Interview for Infants and the Young Children and the Child Behavior Checklist-Posttraumatic Stress Disorder scale (CBCL-PTSD) consisted of 15 items from the CBCL.All of the participantsresided in Longtoushan settlement and Longtoushan town (the epicenter).They were randomly visited from west to east in that region.Results:The rate of scored 9 (or more) on the CBCL-PTSD among children was 51.9％ (27/52) in 1-2 months after the earthquake.However,based on the Semi-Structured Interview,the rate of the children's posttraumatic stress symptoms was 26.9 ％ (14/52).The numbers of posttraumatic stress symptoms,intrusion symptoms,avoidance symptoms,hyperarousal symptoms,the new symptoms and the CBCL-PTSD scores were positively correlated (0.30-0.73,P ＜0.05),except the relation between intrusion symptoms and hyperarousal symptoms.The rate of intrusion symptoms was significant higher among those who experienced earthquake than those who didn't (96.2％ vs.60.0％,P ＜0.01).And the rate of intrusion symptoms was also higher among those who was injured during the earthquake than those who wasn't (100％ vs.84.6％,P ＜ 0.05).And the other symptoms were not difference in children under different conditions (P ＞ 0.005).Conclusion:The preschool children who experienced earthquake or were injured suffer more posttraumatic stress symptoms.
ABSTRACT
Objective@#To explore the psychological status and related factors in patients with precancerous of esophageal and gastric cardia in Linzhou of Henan.@*Methods@#Clinical psycho-rating scale of Social Support Rating Scale (SSRS), Self-Rating Anxiety Scale (SAS, score ≥50 points with symptoms of anxiety) and Self-Rating Depression Scale (SDS, score ≥53 points with the symptoms of depression) were applied to survey life events and psychological status of subjects who aged 40-69 years old and participated in"The Early diagnosis and Early Treatment"program in Linzhou cancer hospital from July 2015 to Jan 2016. Patients with lower intraepithelial neoplasia or high-grade intraepithelial neoplasia were selected as precancerous lesions (n=118), and patients with normal grade were selected as healthy controls (n=210). Compare the differences of the scores between the two groups, and the logistic regression model was used to analyze the related factors of precancerous lesions and psychological status of the study subjects.@*Results@#Precancerous lesions included esophageal (72 cases), gastric cardia (40 cases), esophageal and cardia dual source (6 cases); Precancerous lesions and healthy controls aged (57.17±7.71) and (53.12±7.99) years old, the difference was statistically significant (P<0.001). The anxiety and depression scale showed that the scores of SAS and SDS scores in the precancerous lesions were (37.18±10.01), (40.44±8.37) points, and (34.02±6.63), (38.49±8.73) points in control group, the difference was statistically significant (P=0.002, 0.032). While the social support total score (38.26±5.26), and subjective support score (24.08±3.83) and objective support score (7.50±1.89) in control group were all higher than those of precancerous group (36.80±6.18, 23.01±3.93, 6.93±1.57), and the difference were statistically significant (P=0.024, 0.016, 0.004). In addition, the Logistic analysis showed that subjects with low objective social support, subjective social support and anxiety symptoms were more likely to develop precancerous lesions, and the OR were 0.81, 0.72 and 1.05, respectively (P=0.028, 0.005, 0.009).@*Conclusion@#Social support, anxiety and depression status may be related to the occurrence and development of esophageal and gastric cardia precancerous lesions.
ABSTRACT
Objective:To examine the relationships between acute stress disorder (ASD) symptoms,posttraumatic stress disorder (PTSD) symptoms and depressive symptoms in children survivors following the Lushan earthquake in China.Methods:One hundred ninety-seven children aged 1 to 14years (93 male and 104 female) were followed up at two and six weeks after Lushan earthquake.The ASDS,UCLA PTSD Reaction Index and DASS were used to measure the ASD,PTSD and depressive symptoms.Results:The average scores of ASDS and the depression subscale of DASS at two weeks after earthquake were(36.5 ± 10.9) and (3.3 ± 2.8),respectively.The average scores of UCLA PTSD Reaction Index and the depression subscale of DASS-21 at six weeks after earthquake were (18.5 ± 12.6) and (3.3 ± 3.5),respectively.The rates of ASD and PTSD were 28.6％ and 8.2％,respectively.The cross-lagged structural equation analysis with latent variables indicated that the ASD symptoms at two weeks after earthquake positively predicted PTSD symptoms (β =0.59,p ＜ 0.001) and depressive symptoms (β =0.29,p ＜0.001) at six weeks after earthquake.But there was no significant association between depressive symptoms at two weeks and PTSD symptoms at six weeks after earthquake.Conclusion:ASD symptoms in the early time postearthquake could predict subsequent PTSD and depressive symptoms,while depressive symptoms tend to remain stable within six weeks after earthquake.
ABSTRACT
Objective To test the reliability and validity of the short version of depression-anxiety-stress scale (DASS-21) for students in the disaster region.Methods DASS-21 and the Chinese version of UCLA PTSD Reaction Index for DSM-IV,Revision I were used to evaluate psychological health among 876 students from grades 5 to 9 after Ya' an earthquake.Results (1) Each of the items had a good distinction degree,with CR value ranging from 9.268 to 22.438 (P＜ 0.01),and the correlation coefficients ranged from 0.306 to 0.742.(2)The Cronbach' s alpha coefficients ranged from 0.781 to 0.911.(3) The correlation coefficients between total score and each dimension ranged from 0.714 to 0.914,and the correlation coefficient between PTSD and total DASS score,depression anxiety and stress score was 0.626-0.774.(4)Through the item analysis and explore factor analysis,the revised scale contained 21 items and 3 subscales which could explain 47.813％ of the total variance(KMO =0.937,x2 =3126.85,df=210,P＜0.01),and the results of confirmatory factor analysis supported the three-factor model (x2/df=4.180,P＜0.01,PCFI =0.728,CFI =0.904,IFI =0.905,TLI =0.881,and RMSEA =0.060),and the load of each item was between 0.339 to 0.715.Conclusion The short version of DASS-21 is reliable and valid,and can be used as a tool for post-disaster stress assessment on local students.
ABSTRACT
Objective To conduct a preliminary examination of the factor structure and the reliability and validity of a revised Chinese version of the State-Trait Anxiety Inventory-Form Y (STAI-Y) by using the large sample of migrant children.Methods Perform Exploratory Factor Analysis with half of the data (n =5477) from a large-scale questionnaire survey of students in Grades 4-9 at 58 schools for migrants in Beijing,then conduct Confirmatory Factor Analysis with the other half (n =5476).Results The results of state anxiety and trait anxiety both showed two factors.However,the indicators of trait anxiety were not ideal as seen from the following:the total explained variance was 39.22％,the relationship between the factors and items was not in accordance with the original English version,and the correlation between the two factors was unstable in the different samples (r =-0.17,P ＜ 0.001 ; r =-0.06,P ＜ 0.001).In addition,the factor loading of items 24 ( I wish I could be as happy as others) was low.Conclusion The state anxiety portion of this revised Chinese version of the STAI-Y is structured by the factors state anxiety present and state anxiety absent,and with good reliability and validity as well.Nevertheless,the trait anxiety portion of this revised Chinese version of the STAI-Y is structured by the factors trait anxiety present and trait anxiety absent,it shows unstable reliability and validity.
ABSTRACT
Objective To improve mental health of children in the rural area by intervention with moviewatching.Methods The participants were 438 students from Anhui province,including 273 students in grade 5 from two primary schools and 165 students in grade 2 from two middle schools.Subjects were randomly divided into two groups:an intervention group with movie-watching (n=188)and a control group(n=250).Results The inter-group difference between the pre-measurement and the post-measurement on depression and anxiety of the intervention groups and the control groups in grade 5 from two primary schools was not significant,while the intergroup difference between the pre-measurement and the post-measurement on value8(the intervention group (2669.52±2216.43),the control group(316.57±1410.83)),and the inter-group difference was significant(t_(values)=10.721,P=0.000).The inter-group difference between the pre-measurement and the post-depression, anxiety and values of the interntion groups and the control groups in grade 2from two middle schools was significant(t _(depression)=2.046,P=0.043;t _(state amxoetu)=3.507,P=0.001;t _(trait anxiety)=3.392,P=0.001;t _(values)=5.022,P=0.000)respectively).The intervention effect on mood of depression,anxiety and the values of intervention groups in grade 5 from two primary schools was not significant,while significant on values(F=91.62,P=0.000);while that of intervention groups in grade 2 from two =0.000 respectively).Conclusion Movie-watching intervention wag an effective way to improve middle school students' mental health and to develop correct values.Movie-watching should be an alternative way to improve met-al health of children in rural area for its operability.
