2024 Vol. 12, No. 3 Published: 2024-05-30 Review Article Case study        Article 169 Relationship between psychological stress and problematic social media use among university students: mediating role of depression WANG Huizhe, JIANG Yongzhi DOI: 10.3969/j.issn.2095-4301.2024.03.001 Objective To explore the relations between psychological stress and problematic social media use among university students, and investigate the mediating role of depression between them. Methods From October toNovember 2022, 376 university students were surveyed by using Chinese version of perceptual stress scale（CPSS）, self-rating depression scale（SDS）, and problematic social media use scale. The relations among various variables were analyzed and the mediating effect of depression was investigated. Results The total score of CPSS was 38.30±7.097. There were significantly positive correlations among psychological stress, degree of problematic social media use, andthe level of depression（all P<0.01）. Psychological stress had a directly positive predictive effect on problematic socialmedia use（β=0.385, P<0.05）. The mediating effect of depression between psychological stress and problematicsocial media use was significant（indirect effect 0.095 , accounting for 24.68% of the total effect, Bootstrap 95 %CI 0.007-0.82）. Conclusion The surveyed group has a high level of psychological stress. Depression as a mediating variable affects the relationship between psychological stress and problematic social media use. The results suggest that intervening depression and psychological stress can reduce the use of problematic social media among university students. 2024 Vol. 12 (3): 169- [Abstract] ( 1070 ) HTML (1 KB)  PDF (731 KB)  ( 1065 ) 174 Relationship between dispositional flow and internet gaming disorder among university students: chain mediated effects of meaning in life and life satisfaction HUANG Shihua, WU Qilin, HUANG Zhihao, CHEN Mei, YANG Qianqian DOI: 10.3969/j.issn.2095-4301.2024.03.002 Objective To explore the relationship between dispositional flow and internet gaming disorder among university students, and investigate mediated effects of meaning in life and life satisfaction. Methods By using convenient sampling method, 2 770 university students from a certain university in Guangzhou were selected. They accomplished short dispositional flow scale, meaning in life questionnaire, life satisfaction scale, and internet gaming disorder questionnaire. The relations among the variables and possible moderated mediating relationships were analyzed. Results Dispositional flow, meaning in life, and life satisfaction were mutually significantly positively correlated. Dispositional flow, meaning in life, and life satisfaction were significantly negatively correlated with internet gaming disorder. The direct effect of dispositional flow on internet gaming disorder was significant, and it could also act on internet gaming disorder through independent mediating pathway of meaning in life or life satisfaction and the chain mediating effect of meaning in life and life satisfaction. Conclusion Dispositional flow reduces the risk of internet gaming disorder of university students through direct effects or chain mediating effect of life meaning and life satisfaction. 2024 Vol. 12 (3): 174- [Abstract] ( 1044 ) HTML (1 KB)  PDF (746 KB)  ( 933 ) 180 Diagnostic value of integrated visual and auditory continuous performance test in children with attention deficit and hyperactivity disorder at different ages SHEN Zhimin, ZHANG Yiwen, YU Xiaodan, YANG You DOI: 10.3969/j.issn.2095-4301.2024.03.003 Objective To investigate the diagnostic value of integrated visual and auditory continuous performance test（IVA-CPT）in children with attention deficit and hyperactivity disorder（ADHD）at different ages. Methods A total of 604 children aged 6 to 16 years with suspected ADHD from March 2021 to July 2022 were collected. The Diagnostic and Statistical Manual of Mental Disorders, 5 th edition（DSM-5）was used as diagnostic criteria to retrospectively analyze the results of IVA-CPT. Children were grouped by age to compare the differences between the two evaluation methods（DSM-5 and IVA-CPT）. Results The sensitivity of IVA-CPT was 60.00%-82.22% and the specificity was 51.28%-63.16%. There were average to moderate agreements between DSM-5 and IVA-CPT in the 6-11 years old groups（Kappa=0.275-0.407, P<0.05）. The classification results of ADHD in each group by using IVA-CPT showed that the sensitivity of attention deficit type was 51.52%-75.00% and the specificity was 52.63%-68.89%; the sensitivity of hyperactivity/impulsivity type was 40.90%-66.67% and the specificity was 55.71%-92.16%; the sensitivity of combined type was 40.00%-62.50% and the specificity was 67.86%-91.38%. There were statistically general agreements between the two assessments in 6-10years old groups with attention deficit type（Kappa=0.238-0.374 , P< 0 .05）and in 6 years old group with hyperactivity/impulsivity type（Kappa=0.374, P<0.05）. Conclusion IVA-CPT is suitable for screening ADHD in children aged 6-10 years. For children aged 11 and above, a comprehensive judgment should be made based on clinical observations and other test results. In classification diagnosis, IVA-CPT has certain auxiliary diagnostic value in children aged 6-10 years with attention deficit type. For children aged 11 and above with attention deficit type and children of all ages with hyperactivity/ impulsivity and mixed ADHD, it should be cautious to use IVA-CPT assessment. 2024 Vol. 12 (3): 180- [Abstract] ( 1144 ) HTML (1 KB)  PDF (797 KB)  ( 730 ) 186 Timeliness study of effects of transcranial direct current stimulation in bilateral prefrontal region on counter movement jump LIU Dongxue, XI Rui, ZHOU Zhexiao DOI: 10.3969/j.issn.2095-4301.2024.03.004 Objective To explore the influence of transcranial direct current stimulation（tDCS）on the countermovement jump（CMJ）ability. Methods Twenty-one college students（ordinary college students group）and 17 collegeathletes（college athletes group）randomly received anodic tDCS（a-tDCS）and sham tDCS（s-tDCS）in prefrontal region under 2 mA for 20 min. After these two kinds of stimulation were completed, the CMJ data of these subjects were collected at 0, 10, 20, 30, and 40 min. The two-way repeated-measures ANOVA（stimulation type × test time point）was adopted to analyze the changes in the jump height, acceleration, peak power, and peak vertical ground reaction force（vGRF）. Results There were significantly interactive effects between jump height and peak vGRF（stimulation type × test timepoint）in the college athletes group. The simple effects analysis revealed that the data at five different time points after a-tDCS in the college athletes group were significantly better than the baseline value and those after s-tDCS（P<0.05）. There were significantly main effects on acceleration and peak power under the stimulation type among college athletes.There were significantly interactive effects on acceleration, peak power, peak vGRF（stimulation type × test time point） in the ordinary college students group. The simple effects analysis revealed that the data at five different time points after a-tDCS in the ordinary college students group were significantly better than the baseline value and those after s-tDCS （P< 0 .05）. There was significantly main effect on jump height under the stimulation type among ordinary college students. Conclusion In the prefrontal area, a-tDCS can promote the improvement of multiple indicators in the CMJ process, and some indicators have a certain degree of sustainability. It is expected to consider a-tDCS as one of the methods to enhance the CMJ ability. 2024 Vol. 12 (3): 186- [Abstract] ( 932 ) HTML (1 KB)  PDF (936 KB)  ( 547 ) 192 Relations between personality traits and fear of missing out of university students: mediating role of positive psychological capital ZHENG Xiaoyan, YIN Zijun, XUAN Bin DOI: 10.3969/j.issn.2095-4301.2024.03.005 Objective To explore the impact of personality traits on fear of missing out of university students and its mechanism. Methods A total of 622 university students were investigated by using the ten-item personality inventory in China（TIPI-C）, fear of the missing out scale, and positive psychological capital questionnaire. The relations among personality traits, degree of fear of missing out, and positive psychological capital status of university students, as well as possible mediating effects were analyzed. Results Each dimension of the big five personality was significantly negatively correlated with the fear of missing out, and significantly positively correlated with positive psychological capital. Positive psychological capital was significantly negatively correlated with the fear of missing out. Each dimension of the big five personality directly negatively predicted fear of missing out and positively predicted positive psychological capital. Positive psychological capital directly negatively predicted the fear of missing out. Positive psychological capital partially mediated the relationship between each dimension of the big five personality and the fear of missing out. Conclusion The personality traits of university students can directly affect fear of missing out, and have an impact on fear of missing out through the mediating effect of positive psychological capital. 2024 Vol. 12 (3): 192- [Abstract] ( 1007 ) HTML (1 KB)  PDF (771 KB)  ( 615 ) 199 Parental phubbing and vocational school students’ internet deviant behavior: mediating role of core self-evaluation ZHANG Yali, JIN Kangyue, ZHOU Xuan, HAN Haibin DOI: 10.3969/j.issn.2095-4301.2024.03.006 Objective To explore the characteristics, influence factors, and mechanism of vocational school students’ internet deviation behavior. Methods The parents phubbing scale, core self-evaluation scale, and internet deviant behavior inventory were used to survey 459 vocational school students. The relevant data were analyzed by SPSS 24.0 and AMOS 24.0 softwares. Results There were gender and grade differences in internet deviant behavior among vocational school students. There were significant mutual correlations among parental phubbing, core self-evaluation, and internet deviant behavior. Core self-evaluation played a partial mediating role between parental phubbing and internet deviant behavior. Conclusion Parental phubbing can not only directly affect internet deviation behavior, but also indirectly influence internet deviation behavior through core self-evaluation. 2024 Vol. 12 (3): 199- [Abstract] ( 958 ) HTML (1 KB)  PDF (789 KB)  ( 686 ) 204 Discussion on application of information-based continuous health management mode to postpartum maternal and infant health care JIA Yanfeng DOI: 10.3969/j.issn.2095-4301.2024.03.007 Objective To discuss the application effect of the information-based continuous health management mode on the postpartum maternal and infant health care service. Methods A total of 220 postpartum women who gave birth at the Department of Obstetrics and Gynecology, Gansu Provincial Maternal and Child Health Hospital were selected as the research subjects, and they were randomly divided into control group and intervention group. The control group received routine postpartum health care, while the intervention group adopted an information-based continuous health management mode. The maternal and infant health status and psychological health status of postpartum women were compared between the two groups during the puerperium and 3 months after delivery. Results During the puerperium period, exclusive breastfeeding rate and postpartum pelvic floor muscle exercise in the intervention group were significantly better than those in the control group（P<0.01）. Incident rates of insufficient milk secretion, mastitis, neonatal umbilical infection, and neonatal diaper rash in the intervention group were significantly lower than those in the control group（P<0.05）. At the end of 3-month postpartum period, exclusive breastfeeding rate in the intervention group was significantly higher than that in the control group （P< 0 .01）; incident rates of mastitis, postpartum depression, and infant dyspepsia in the intervention group were significantly lower than those in the control group（P<0.05, P<0.01）. Conclusion The use of information-based postpartum continuous health management mode can promote maternal and infant health and reduce the incidence of maternal depression. 2024 Vol. 12 (3): 204- [Abstract] ( 912 ) HTML (1 KB)  PDF (732 KB)  ( 718 ) 209 Implementation of comprehensive nursing for adolescents with attempted suicide and construction of post-discharge service plan ZHAO Huiyun, HU Yaqin, WANG Xiaojing, ZHANG Lingping DOI: 10.3969/j.issn.2095-4301.2024.03.008 Objective To provide comprehensive nursing for adolescents with attempted suicide, and construct a post-discharge service plan. Methods Comprehensive nursing was provided to two adolescents hospitalized after attempted suicide, which included safety nursing management, condition observation, prevention of complications, and personalized psychological care. A post-discharge service plan was constructed through literature search and expert argumentation. Results After surgery and comprehensive nursing, the condition of the two adolescents was stable and there were no serious complications. The psychological state significantly improved, showing positive and optimistic attitude. The post-discharge service plan included strengthening safety management, preventing complications, and personalized psychological support. Conclusion For adolescents who attempted suicide, comprehensive nursing during hospitalization can effectively reduce the risk of suicide, and a post-discharge service plan can help stabilize their emotions. 2024 Vol. 12 (3): 209- [Abstract] ( 982 ) HTML (1 KB)  PDF (709 KB)  ( 604 ) 213 Effect of peer phubbing on high school students’ mobile phone addiction: mediating effect of social self-efficacy and loneliness HUANG Yanqing, WU Junlin, QIU Junlin, LONG Qianmei, HUANG Bin, HUANG Guoping DOI: 10.3969/j.issn.2095-4301.2024.03.009 Objective To explore the relations among peer phubbing, social self-efficacy, loneliness, and mobile phone addiction of high school students. Methods By using peer phubbing scale, social self-efficacy scale, UCLA loneliness scale, and mobile phone addiction scale, 14 036 high school students from five schools in Zizhong County, Sichuan Province completed a cross-section questionnaire survey. Correlation analysis and chain mediation effect test were carried out on relevant data. Results Correlation analysis showed that peer phubbing was significantly positively correlated with loneliness and mobile phone addiction, but significantly negatively correlated with social self-efficacy. Loneliness was significantly positively correlated with mobile phone addiction. Social self-efficacy was significantly negatively correlated with loneliness and mobile phone addiction. Mediation analysis showed that peer phubbing had a significant direct effect on high school students’ mobile phone addiction. Social self-efficacy and loneliness played a single mediating role and a chain mediating role respectively in the effect of peer phubbing on mobile phone addiction in high school students. The total indirect effect accounted for 24.3%. Conclusion The peer phubbing can directly increase the risk of mobile phone addiction in high school students. Social self-efficacy and loneliness are the internal psychological mechanisms behind this relationship. 2024 Vol. 12 (3): 213- [Abstract] ( 1001 ) HTML (1 KB)  PDF (805 KB)  ( 666 ) 219 Relations between alexithymia, loneliness, resilience, and non-suicidal self-injury behaviors in adolescents with depression ZHANG Bing, CHEN Yang, FU Wenxian, JIANG Cheng, ZHANG Wei, HE Kongliang DOI: 10.3969/j.issn.2095-4301.2024.03.010 Objective To explore the relations between alexithymia, loneliness, resilience, and non-suicidal self-injury（NSSI）behaviors in adolescents with depression, and investigate the mechanism. Methods The functional assessment of self-mutilation（FASM）, Toronto alexithymia scale（TAS）, UCLA loneliness scale, and the Connor-Davidson resilience scale（CD-RS-10）were used to investigate 326 adolescents with depression. The relations among the variables and possible moderated mediating relationships were analyzed. Results Alexithymia and loneliness were significantly positively correlated with the NSSI behaviors, while resilience was significantly negatively associated with NSSI behaviors. Compared with non-NSSI group, total score of alexithymia, difficulties in emotion recognition and description, scores of extraversion thinking dimension, and total score of loneliness in the NSSI group were significantly higher, while the score of resilience was significantly lower（P<0.01）. Alexithymia positively predicted the development of NSSI, while resilience negatively predicted the development of NSSI. Alexithymia influenced NSSI through the mediating role of resilience, and loneliness moderated the first half of this mediating model. Conclusion Loneliness, resilience, and alexithymia of adolescents with depression are significantly correlated with NSSI behaviors. Alexithymia is a risk factor for the development of NSSI, while the resilience is a protective factor in reducing NSSI behaviors. Resilience plays a mediating role in the relationship between alexithymia and NSSI behavior, with loneliness playing a moderating role. 2024 Vol. 12 (3): 219- [Abstract] ( 946 ) HTML (1 KB)  PDF (807 KB)  ( 794 )        Case study 225 A case report of nutritional supplement improving hypersomnia in children and literature review HAN Xiaolong, JIANG Yanrui DOI: 10.3969/j.issn.2095-4301.2024.03.011 A 7-year-old boy presented excessive daytime sleepiness for more than 3 months. He was diagnosed as idiopathic hypersomnia by doctor’s consultation, polysomnography, multiple sleep latency tests, and laboratory tests（serum iron 6.7 μmol/L, serum 25 hydroxyvitamin D 20.00 ng/mL, with no other abnormalities）. In the absence of common etiology to explain the patient’s symptoms, we first conducted sleep hygiene guidance for the patient and provided targeted supplementation of vitamin D and iron elements. After 8 months, the child’s sleepiness improved significantly, with an increase in serum iron concentration and 25 hydroxyvitamin D level. Excessive daytime sleepiness is a potential danger for children, and in addition to considering common causes, attention should also be paid to the role of nutrient deficiencies. 2024 Vol. 12 (3): 225- [Abstract] ( 930 ) HTML (1 KB)  PDF (752 KB)  ( 498 )        Review 229 Advances in statistical learning among bilinguals LI Gengchun DOI: 10.3969/j.issn.2095-4301.2024.03.012 Bilinguals, who can use two languages, have cognitive advantages. In recent years, the ability of bilinguals in statistical learning has attracted widespread attention from the academic community. Statistical learning, as an important component of human cognition, refers to the process in which individuals gradually discover the statistical regularities in a continuous stream of external stimuli. This paper reviews the relevant foreign literature on bilingual statistical learning, and explores its developmental trends. 2024 Vol. 12 (3): 229- [Abstract] ( 954 ) HTML (1 KB)  PDF (728 KB)  ( 655 ) 236 Application and reflection on medical and educational intervention in treatment of autism spectrum disorder FENG Yuqing, ZHAO Zhongwei DOI: 10.3969/j.issn.2095-4301.2024.03.013 Autism spectrum disorder（ASD）is a common neurodevelopmental disorder. ASD children have poor prognosis and lack independent survival ability, which takes a heavy burden to their families and society. In recent years, the prevalence of ASD has continued to rise. Medical and educational intervention has also been a hot topic in the special education sector. This article discusses the problems in the application of medical and educational intervention to treatment of ASD, and puts forward optimization suggestions. 2024 Vol. 12 (3): 236- [Abstract] ( 976 ) HTML (1 KB)  PDF (701 KB)  ( 707 ) 239 Connotation, physiological basis, and intervention of dating violence WEI Shujing, SUN Shengtao DOI: 10.3969/j.issn.2095-4301.2024.03.014 Dating violence is a form of violence that uses physical compulsion, psychological force, and risky behavior to validate the affection of intimate partner, which causes serious harm to adolescents. The physiological basisof dating violence involves genetics, hormone levels（such as cortisol and testosterone）, brain injury, and executive dysfunction. During intervention, we should change the victims’ cognition, guide peer and bystander behavior, and strengthen family support. Future studies should explore the relationship between self-cognition and victimization, and the mechanism of steroid action, and integrate personality pathology and evolutionary theory to comprehensively analyze dating violence. 2024 Vol. 12 (3): 239- [Abstract] ( 962 ) HTML (1 KB)  PDF (722 KB)  ( 859 )
