Objective: To investigate the prevalence and influencing factors of menopausal syndrome among postmenopausal women in Pan'an County, Zhejiang Province, so as to provide the basis for guiding the health management of postmenopausal women. Methods: From May 2023 to April 2024, the postmenopausal women aged 40 to 69 years in Pan'an County were selected using the random cluster sampling method. Demographic information, lifestyle and prevalence of gynecological diseases were collected through questionnaire surveys. The prevalence of menopausal syndrome was assessed by modified Kupperman Score Scale. Factors affecting menopausal syndrome were analyzed by a multivariable logistic regression model. Results: A total of 816 postmenopausal women were surveyed, with an mean age of (57.63±2.92) years and a mean natural menopause age of (49.85±2.13) years. There were 574 cases with menopausal syndrome, with a prevalence of 70.34%. Flashes and sweating, insomnia and irritability were common symptoms, accounting for 62.87%, 47.43% and 41.18%, respectively. Multivariable logistic regression analysis showed that monthly personal income of ≤5 000 yuan (<3 000 yuan, OR=3.124, 95%CI: 1.829-5.335; 3 000-5 000 yuan, OR=2.399, 95%CI: 1.370-4.201) and having gynecological diseases (OR=1.970, 95%CI: 1.292-3.004) were associated with a higher risk of menopausal syndrome, while average (OR=0.141, 95%CI: 0.072-0.276) or sufficient sleep quality (OR=0.095, 95%CI: 0.049-0.185) were associated with a lower risk of menopausal syndrome. Conclusion The prevalence of menopausal syndrome among postmenopausal women in Pan'an County is relatively high, and is mainly influenced by personal economic status, sleep quality and the presence of gynecological diseases.

Objective:To test the validity and reliability of the Chinese version of the Cyberbullying Bystand-er Scale(CBS)in Chinese college students.Methods:Totally 722 college students were randomly divided into sample 1(n=356)and sample 2(n=366).Exploratory factor analysis was performed on sample 1,and confirma-tory factor analysis,criterion validity,and internal consistency reliability were performed on sample 2.The criterion validity was tested with the Short Form of Moral Disengagement Scale(MDS).Thirty-seven students of sample 2 were randomly selected and retested 2 week later.Results:The Chinese version of CBS contained 6 distinct factors(40 items),named passive outsider online,defender of the cybervictim online,reinforcer of the cyberbully online,passive face-to-face outsider,face to face defender of the cybervictim,face-to-face reinforcer of the cyberbully.The results of confirmatory factor analysis confirmed that the fitting index of the six-factor modelis good(x2/df=2.83,CFI=0.90,TLI=0.89,RMSEA=0.07,SRMR=0.06).The scores of passive outsider online,reinforcer of the cyberbully online,passive face-to-face outsider and face-to-face reinforcer of the cyberbully were positively correla-ted with the moral disengagement(ICC=0.11-0.28,Ps＜0.05).The internal consistency reliabilities of the scale were from 0.89 to 0.96,the retest reliabilities(ICC)of the scale were between 0.75 to 0.89.Conclusion:The Chinese version of the Cyberbullying Bystander Scale(CBS)shows good validity and reliability in Chinese college students.

Objective:To investigate the relationship between basic psychological needs satisfaction, family resilience and psychological resilience with self-neglect in older adults on maintenance hemodialysis, and to analyze the mediating effect of family resilience and psychological resilience between basic psychological needs satisfaction and self-neglect.Methods:The social demographic questionnaire, basic psychological needs satisfaction scale, the Connor-Davidson resilience scale 10-item, family resilience questionnaire and scale of the elderly self-neglect were applied to 623 older adults on maintenance hemodialysis randomized sampled from 50 hemodialysis centers in Hunan Province from July to December 2021. The data were statistically described and mediated pathway analysis was performed using SPSS 28.0 and AMOS 24.0.Results:The scores of basic psychological needs satisfaction, psychological resilience, family resilience and elderly self-neglect in older adults on maintenance hemodialysis were (4.95±1.01), (23.24±8.19), (78.60±12.49) and (7.99±5.60), respectively.Correlation analysis showed that self-neglect was statistically negatively correlated with basic psychological needs satisfaction, psychological resilience and family resilience ( r=-0.398, -0.419, -0.451, all P<0.001), basic psychological needs satisfaction was positively correlated with resilience and family resilience ( r=0.594, 0.534, both P<0.001), and psychological resilience was positively correlated with family resilience ( r=0.477, P<0.001).Analysis psychological of mediation effects showed that basic psychological needs satisfaction had a total effect of -0.462 on self-neglect. The direct effect was -0.113, accounting for 25% of the total effect. The mediating effects of family resilience and psychological resilience were -0.189 and -0.122 respectively, accounted for 41% and 26% of the total effect. The chain mediating effect was -0.038, with an effect size of 8%. Conclusion:Basic psychological needs satisfaction for older adults on maintenance hemodialysis can affect self-neglect either directly or indirectly through family resilience and psychological resilience, and self-neglect can be reduced in the future by increasing family resilience and psychological resilience through meeting the basic psychological needs of older adults on maintenance hemodialysis.

Objective To understand the proficiency level and sources of Traditional Chinese Medicine(TCM)health education among hemodialysis patients,in order to provide the basis for promoting the application of TCM nursing in hemodialysis patients.Methods Utilizing a convenience sampling approach,we conducted a survey from April to May 2023 involving hemodialysis patients from 7 tertiary TCM hospitals across Beijing,Hebei Province,Sichuan Province,and other regions.Custom-made questionnaires were utilized,gathering general information,respons-es conceming the level of mastery on TCM health education,and their primary sources of such knowledge.Results A total of 413 questionnaires were disseminated,and 392 proved valid,yielding a valid response rate of 94.92％.The score of patient's knowledge on TCM health education averaged(8.25±3.73),and an average score rate of 48.53％was obtained.In the patients undergoing hemodialysis,a relatively larger number of people possess knowl-edge of TCM health knowledge about relieving symptoms(50.8％～55.9％)and traditional Chinese daily life routines(56.4％～90.1％).However,fewer people are aware of how to use the five-tone therapy method for emotional inter-vention(40.8％)and principle of taking restorative Traditional Chinese Medicine(24.5％～36.7％),the dietary prin-ciples of"nurturing yang in spring and summer,and nurturing yin in autumn and winter"(14.3％),and theories of TCM kidney functions(9.9％).Approximately 23.0％of the patients sourced their TCM health education knowledge from new media platforms.Compared with new media method alone,patients who utilized only traditional education-al platforms(P=0.020),and those who combined both new media and traditional methods(P=0.018)demonstrated higher proficiency in TCM health education.Conclusion Hemodialysis caregivers are urged to develop a TCM health education framework that emphasizes emotional well-being and traditional wellness concepts,thereby fostering patient-centric TCM health ideologies.Hemodialysis education personnel are encouraged to leverage new media whilst ensuring education quality and effective outcomes.

Objective:To explore the efficacy of online problem management plus (PM+) intervention on the mental health among adults with anxiety.Methods:Ninety subjects with anxiety (Generalized Anxiety Disorder-7 (GAD-7) total score≥5) were enrolled and randomly allocated into either waiting group or online PM+group. Participants in the online PM+intervention group received online PM+intervention twice a week for 3 weeks, while participants in the waiting group received general psychological supports. Psychological evaluation was performed at the end of the 3-week treatment and at 6 months after treatment. Outcome measures included GAD-7, Patient Health Questionnaire -(PHQ-9), Patient Health Questionnaire-15 (PHQ-15), Perceived Stress Scale-14 (PSS-14), and Insomnia Severity Index (ISI). Two-factor repeated measure analysis of variance (ANOVA) was used to compare the scores of the two groups at baseline and after intervention. Single-factor repeated measure analysis of variance was used to compare the differences of scores at baseline,3-week post-intervention, and 6-month follow-up in the online PM+ group.Results:A total of 37 (37/45) pations in the online PM+intervention group and 30 (30/45) patients in the waiting group completed the psychological evaluation after intervention. After 3-week intervention, compared with baseline, no significant change was found in the scores of GAD-7 ( F=0.08, P=0.782), PHQ-9 ( F=0.33, P=0.570), PHQ-15 ( F=0.20, P=0.660), PSS-14 ( F=0.14, P=0.05) and ISI ( F=0.02, P=0.880) in the waiting group. The changes of GAD-7 ( F=22.61, P<0.001), PHQ-9 ( F=19.49, P<0.001), PHQ-15 ( F=12.67, P=0.001), PSS-14 ( F=16.69, P<0.001) and ISI ( F=5.59, P=0.022) scores in the online PM+group were statistically significant. There were significant differences in GAD-7 (9.7±5.2 vs. 5.0±3.5, F=17.11, P<0.001), PHQ-9 (11.4±5.9 vs. 6.9±4.7, F=11.65, P=0.002), PHQ-15 (10.4±5.4 vs. 6.3±4.1, F=12.24, P=0.002) and PSS-14 (26.0±7.5 vs.31.8±9.9, F=6.59, P=0.016) scale scores between the online PM+group and the waiting group after intervention. In addition, the scores of GAD-7 (95% CI=1.25-6.47, P=0.002) and PHQ-9 (95% CI=2.21-9.10, P=0.005) scales in the online PM+group still had statistically significant differences compared to the baseline at the 6-month follow-up. Conclusions:In this study, online PM+intervention significantly alleviated symptoms of anxiety, depression, somatization, stress, and insomnia in adults, and the therapeutic benefits of PM+persisted for at least 6 months.
