Objective:To investigate anxiety symptoms and associated factors in relocated elderly residents of new townships,and to provide evidence for prevention interventions.Methods:A cross-sectional study was conduc-ted in relocated elderly residents in new townships of three urban areas in Shandong Province from 2021 to 2023.The study instruments included Ascertain Dementia-8,Generalized Anxiety Disorder-7,self-administered de-mographic characteristics information questionnaire.Multivariate analysis of factors associated with anxiety symp-toms in elderly residents was performed using multivariate logistic regression.Results:The prevalence rate of mild anxiety symptoms was 5.8％,and the rate of moderate-to-severe anxiety symptoms was 1.3％in 3 313 resi-dents.Multivariate analysis found that self-assessed general psychological condition(OR=0.52),good family envi-ronment(OR=0.34),no self-perceived cognitive impairment(OR=0.31),no chronic diseases(OR=0.42),and only one chronic disease(OR=0.61)were protective factors for mild anxiety symptoms,and very good dietary structure(OR=2.15)and fair dietary structure(OR=2.39)were risk factors for those.Very good family environ-ment(OR=0.11)and average family environment(OR=0.16),and no self-perceived cognitive impairment(OR=0.14)were protective factors for moderate-to-severe anxiety symptoms,and 0-3 years(OR=3.24)and 4-6 years(OR=3.28)of relocation were risk factors for those.Conclusion:Family environment,dietary structure,and duration since relocation are key factors associated with anxiety symptoms among relocated elderly residents in new townships.Targeted interventions should be implemented to address their mental health needs.

Objective:To investigate the impact of traumatic experiences on panic attack,depression and anxi-ety symptoms among community residents.Methods:Totally 11 280 community residents were recruited.The Com-posite International Diagnostic Interview-3.0,Patient Health Questionnaire,7-item Generalized Anxiety Disorder Scale and general information questionnaire were used for face-to-face interview to collect information.Propensity Score Matching was conducted to match 5 184 community residents for analysis.Logistic regression was employed to analyze the impact of traumatic events on panic attack,depressive symptoms,and anxiety symptoms among the study sample.Results:Traumatic events were associated with a higher likelihood of experiencing panic attack(OR=3.26,95％CI:2.26-4.70),depression symptoms(OR=1.92,95％CI:1.56-2.37)and anxiety symptoms(OR=1.57,95％CI:1.24-1.99).Conclusion:Traumatic events extensively impact the mental health of commu-nity residents.Timely psychological support and early intervention are essential to prevent mental health issues in community residents affected by trauma.

Objective:To explore relationships and differences of perceived social support and depression-anx-iety symptoms between rural-to-urban migrated residents and rural residents.Methods:A total of 5 958 rural-to-ur-ban migrated residents and 4 720 rural residents were recruited.The Patient Health Questionnaire-9,Generalized Anxiety Disorder-7,and Perceived Social Support Scale were used to assess symptoms of depression,anxiety,and social support,respectively.Network estimation,centrality and predictability measurement,accuracy and stability verification,and network comparison were conducted based on R 4.2.0 to compare the network structure differ-ences between the two groups of residents.Results:In rural-to-urban migrated residents,"lack of energy"in depres-sive symptoms and"inability to control worry"in anxiety symptoms were the nodes with the highest expected influ-ence(EI).In rural residents,"low self-evaluation"in depressive symptoms and"difficulty relaxing"in anxiety symptoms were the nodes with the highest EI.The highest node of perceived social support EI for both groups was"support from relatives/leaders."The bridge nodes were the same for rural-to-urban migrated residents and rural residents,with"be down in spirits"being the nodes with the highest bridge expected influence.The results of net-work comparison test showed that the overall network structure of rural-to-urban migrated residents and rural resi-dents was statistically different(P＜0.05).Conclusion:There are correlation and difference among depressive symptoms,anxiety symptoms,and perceived social support in rural-to-urban migrated and rural residents.

Objective:To explore associated factors of post-discharge depressive symptom severity in patients with bipolar disorder.Methods:A longitudinal follow-up was conducted to investigate the demographic,behavioral,and clinical characteristics,and social function among discharged patients with bipolar disorder who met the DSM-5 diagnostic criteria.Clinical characteristics were assessed with the Hamilton Depression Scale(HAMD)and Brief Psychiatric Rating Scale(BPRS).Single factor and multivariate regression were carried out to explore the associat-ed factors of depressive symptom severity in patients with bipolar disorder.Results:A total of 298 discharged pa-tients with bipolar disorder were face-to-face interviewed to complete the follow-up survey.At follow-up time,psy-chotic symptoms(standardized(β)=0.18),housework((β)=0.23),social interaction((β)=0.17)and BPRS total score((β)=0.46)were positively associated with HAMD total score.Productive labor and work((β)=-0.27)and person-al life management((β)=-0.15)were negatively associated with HAMD total scores.Conclusion:Post-discharge depressive symptom severity in bipolar disorder patients is influenced by multiple factors.Effective management of psychotic symptoms,combined with enhanced community-based social rehabilitation and functional recovery,may help reduce the persistence or worsening of depressive symptoms and improve prognosis.

Objective:To develop a Problematic Short Video Use Scale(PSVUS)and evaluate its validity and reliability.Methods:Through literature review and interviews,and with reference to the Diagnostic and Statisti-cal Manual of Mental Disorders,Fifth Edition(DSM-5)diagnostic guidelines for internet gaming disorder,the items were compiled.Initially,979 individuals(aged 14-74 years)participated in the survey,and 362 of them were re-tested after two weeks.The Perceived Stress Scale(PSS-4),UCLA Loneliness Scale(ULS-8),Brief Self-Control Scale(BSCS),and Hospital Anxiety and Depression Scale(HADS)were used to test the criterion-related validi-ty.Multiple classification methods were used to determine the cut-off value.Additionally,a 9-item brief version of the scale(PSVUS-9)was developed.Results:The PSVUS consists of 27 items organized into 9 dimensions(preoc-cupation,with drawal,tolerance,unsuccessful attempts,escape,continuation despite harm,deception,loss of inter-est,and functional impairment),explaining 78.71％of the total variance,with item factor loadings ranging from 0.62 to 0.95.The nine-factor structure exhibited good fit(x2/df=2.00,CFI=0.97,RMSEA=0.05).The scores of the dimensions were correlated with the scores of the PSS-4,ULS-8,BSCS and HADS(ICC=|0.21|-|0.68|,Ps＜0.05).The Cronbach's α coefficient of the PSVUS was 0.95,and the test-retest reliability was 0.83.The cut-off score for problematic use was determineded to be 70 or above.The PSVUS-9 score was correlated with the scores of the criterion measures(ICC=|0.39|-|0.68|,Ps＜0.01).The Cronbach's α coefficient of PSVUS-9 was 0.86 and the test-retest reliability was 0.80.A score of 24 or higher on the PSVUS-9 was indicative of problematic use.Conclusion:The Problematic Short Video Use Scale(PSVUS)and its brief version demonstrate good validity and reliability,and could be used to measure and screen for problematic short video use.
