OBJECTIVES: To investigate the association between childhood trauma and game addiction in adolescents, as well as the mediating effect of self-control. METHODS: A cross-sectional study was conducted using cluster random sampling. The participants were 2 664 adolescents from a senior high school in Henan Province. The research tools included a demographic data questionnaire, Childhood Trauma Questionnaire-Short Form, Self-Control Scale, and Game Addiction Scale for Adolescents. The Bootstrap method was used to test the parallel mediating effect, with the five dimensions of self-control as mediators. RESULTS: The prevalence of game addiction among the adolescents was 17.68% (471/2 664). There was a positive correlation between childhood trauma and game addiction scores (P<0.01), and a negative correlation between childhood trauma scores and each dimension of self-control (P<0.01). Moreover, all five dimensions of self-control were negatively correlated with game addiction scores (P<0.01) and acted as parallel mediators between childhood trauma and game addiction. The mediating effects of restraint from entertainment (accounting for 15.6% of the total effect) and resistance to temptation (accounting for 10.6% of the total effect) were stronger. CONCLUSIONS: Childhood trauma may increase the risk of game addiction by impairing adolescents' self-control abilities. The reduction of childhood trauma can cultivate self-control in adolescents and prevent the occurrence of game addiction.

[Association between maternal job burnout and adolescent depression: the chain mediating effect of maternal depression and parenting style]. / æ¯äº²èŒä¸šå€¦æ€ å’Œé’å°‘å¹´æŠ‘éƒçš„å ³ç³»ï¼šæ¯äº²æŠ‘éƒå’Œæ•™å »æ–¹å¼çš„é“¾å¼ä¸­ä»‹ä½œç”¨.

OBJECTIVES: To investigate the association between maternal job burnout and adolescent depression and the mediating effect of maternal depression and parenting style. METHODS: A cross-sectional study was conducted. The cluster random sampling method was used to select 2 572 adolescents from 7 middle schools in Shanghai, China, from April to May, 2021. A survey was performed for these adolescents and their mothers. The research tools included a general information questionnaire, Maslach Burnout Inventory-General Survey, Center for Epidemiologic Studies Depression Scale, short-form of Egna Minnen av Barndoms Uppfostran, and Children's Depression Inventory. A structural equation model was established, and the Bootstrap method was used to investigate the mediating effect. RESULTS: The detection rate of depressive symptoms was 12.71% (327/2 572) among the adolescents. The scores of maternal job burnout, maternal depression, and negative parenting style were positively correlated with the score of adolescent depression (P<0.05), and the score of positive parenting style was negatively correlated with the score of adolescent depression (P<0.05). Maternal depression and parenting style played a mediating role between maternal job burnout and adolescent depression, including the individual mediating effect of maternal depression, the individual mediating effect of positive parenting style, and the chain mediating effect of maternal depression-negative/positive parenting style. CONCLUSIONS: Maternal job burnout may affect adolescent depression through the mediating effect of depression, parenting style, and depression-parenting style, suggesting that the symptoms of adolescent depression can be reduced by alleviating maternal job burnout, improving maternal depression, increasing positive parenting behaviors, and reducing negative parenting behaviors.

[The influence of family structure on depression and anxiety symptoms in adolescents: the mediating role of emotional neglect]. / å®¶åº­ç»“æž„å¯¹é’å°‘å¹´æŠ‘éƒå’Œç„¦è™‘ç—‡çŠ¶çš„å½±å“ï¼šæƒ æ„Ÿå¿½è§†çš„ä¸­ä»‹ä½œç”¨.

OBJECTIVES: To study the influence of family structure on depression and anxiety symptoms in adolescents and its mechanism. METHODS: The cluster sampling method was used to select the students from seven middle schools in Shanghai, China. An online questionnaire survey was conducted using a self-made general status questionnaire, Childhood Trauma Questionnaire, Children's Depression Inventory, and Screen for Child Anxiety Related Emotional Disorders. The methods including one-way analysis of variance, chi-square test, binary logistic regression analysis, and mediating effect analysis were used to evaluate depression and anxiety symptoms in adolescents and the difference in childhood trauma and its mediating effect. RESULTS: Compared with the adolescents from nuclear families, the adolescents from three-generation lineal families had a lower risk of depression symptoms (OR=0.794, 95%CI: 0.649-0.972, P<0.05), while those from host families had a higher risk of depression symptoms (OR=4.548, 95%CI: 1.113-18.580, P<0.05). The adolescents from inter-generational families and host families had a significantly higher score on the Childhood Trauma Questionnaire subscale of emotional neglect (P<0.05). Emotional neglect played a mediating role in the influence of inter-generational families and host families on depression symptoms in adolescents. CONCLUSIONS: Parents and grandparents have a certain positive effect in family structures. Separation from parents may make adolescents perceive more emotional neglect, which may increase the occurrence of depression symptoms.

OBJECTIVES: To study the association of depression and suicidal ideation with parenting style in adolescents. METHODS: The cluster sampling method was used to select 6 195 junior and senior high school students in Xinxiang City of Henan Province, China, from 2014 to 2018. The survey tools included a general social information questionnaire, the Parental Bonding Instrument, and the Kutcher Adolescent Depression Scale (11 items). A multivariate logistic regression analysis was used to identify the association of depression and suicidal ideation with parenting style in adolescents. RESULTS: There were 6 194 valid questionnaires in total, including 2 586 boys (41.75%) and 3 608 girls (58.25%), with a mean age of (16.4±1.9) years (range: 11-20 years). Among these 6 194 students, 1 333 (21.52%) had depression, and 508 (8.20%) had suicidal ideation. Depression in adolescents was positively correlated with maternal control (OR=1.059, P<0.001) and paternal control (OR=1.061, P<0.001), but negatively correlated with maternal care (OR=0.937, P<0.001) and paternal care (OR=0.917, P<0.001). Suicide ideation in adolescents was positively correlated with maternal control (OR=1.110, P<0.001) and paternal control (OR=1.076, P<0.001), but negatively correlated with maternal care (OR=0.895, P<0.001) and paternal care (OR=0.914, P<0.001). CONCLUSIONS: Parental care may decrease the risk of depression and suicide ideation, while parental control may increase the risk of depression and suicide ideation in adolescents. Citation.

[Association of suicidal ideation with family environment and psychological resilience in adolescents].

OBJECTIVE: To study the association of suicidal ideation with family environment and psychological resilience in adolescents. METHODS: Cluster sampling was used to perform an investigation among 3 230 junior and senior high school students in Xinxiang of Henan Province, China December 2014. A general social information questionnaire, 11-Item Kutcher Adolescent Depression Scale(KADS-11), Family Environment Scale-Chinese Version (FES-CV) and Connor-Davidson Resilience Scale (CD-RISC; Chinese version ) were used for evaluation. A multivariate logistic regression analysis and a case-control study were used to investigate the association of suicidal ideation with family environment and psychological resilience in adolescents. RESULTS: A total of 2 960 usable questionnaires were received. Among the 2 960 adolescents, 247 (8.50%) had suicidal ideation (98 boys and 149 girls). The multivariate logistic regression analysis showed that after adjustment for age and sex, single-parent/remarried family was associated with an increased risk of suicidal ideation (OR=2.655). Suicidal ideation in boys was negatively correlated with family cohesion (OR=0.750, P<0.001) and organization (OR=0.855, P=0.036) and was positively correlated with family conflict (OR=1.159, P=0.017). Suicidal ideation in girls were negatively correlated with family cohesion (OR=0.771, P<0.001), emotional expression (OR=0.815, P=0.001) and intellectual-cultural orientation (OR=0.915, P=0.037). The adolescents with suicidal ideation had a significantly lower total score of psychological resilience than those without suicidal ideation (P<0.05). Compared with those without suicidal ideation, the adolescents with suicidal ideation had significantly lower scores on 4 factors of the CD-RISC (ability, tolerance of negative emotions, acceptance of changes and control) (P<0.05). CONCLUSIONS: Family cohesion is a protective factor against suicidal ideation in adolescents. Family organization in boys and family emotional expression in girls are associated with a decreased risk of suicidal ideation. Enhanced psychological resilience may help to reduce the incidence of suicide ideation in adolescents.

Associations of serotonin transporter gene promoter polymorphisms and monoamine oxidase A gene polymorphisms with oppositional defiant disorder in a Chinese Han population.

BACKGROUND: Oppositional defiant disorder (ODD) is a behavioral disorder that mainly refers to a recurrent pattern of disobedient, defiant, negativistic and hostile behaviors toward authority figures. Previous studies have showed associations of serotonin transporter (5-HTT) and monoamine oxidase A (MAOA) with behavioral and psychiatric disorders. The purposes of this study were to investigate the potential association of 5-HTT gene promoter polymorphism (5-HTTLPR) and MAOA gene polymorphism with susceptibility to ODD in a Han Chinese school population. METHODS: The 5-HTTLPR gene polymorphism and the MAOA gene polymorphism were genotyped in a case-control study of 257 Han Chinese children (123 ODD and 134 healthy controls). RESULTS: There was significant difference in the allele distribution of 5-HTTLPR (χ2 = 7.849, P = 0.005) between the ODD and control groups. Further, there were significant differences in genotype (χ2 = 5.168, P = 0.023) and allele distributions (χ2 = 10.336, P = 0.001) of the MAOA gene polymorphism that is variable-number tandem repeat (MAOA-uVNTR) between two groups. Moreover, there were significant differences in genotype (χ2 = 4.624, P = 0.032) and allele distributions (χ2 = 9.248, P = 0.002) of MAOA-uVNTR only in the male ODD and healthy groups. CONCLUSIONS: Our results suggest that 5-HTTLPR and MAOA-uVNTR gene variants may contribute to susceptibility to ODD. Further, MAOA-uVNTR gene polymorphism may play a role in susceptibility to ODD only in male children.

Association of tryptophan hydroxylase-2 polymorphisms with oppositional defiant disorder in a Chinese Han population.

BACKGROUND: Oppositional defiant disorder (ODD) is a behavioral disorder of school-age population. It is well known that 5-HT dysfunction is correlated with impulsivity, which is one of the common characteristics of ODD. The enzyme tryptophan hydroxylase-2 (TPH-2) synthesizes 5-HT in serotonergic neurons of the midbrain raphe. The purposes of this study were to investigate the potential association of TPH-2 polymorphisms with susceptibility to ODD in a Han Chinese school population. METHODS: Four polymorphisms (rs4570625, rs11178997, rs1386494 and rs7305115) of the TPH-2 gene were analyzed by using polymerase chain reaction and DNA microarray hybridization in a case-control study of 276 Han Chinese individuals (124 ODD and 152 controls). RESULTS: In single marker analyses,there was a significant difference in the genotype (χ 2  = 4.163, P = 0.041) and allele frequency (χ 2  = 3.930, P = 0.047) of rs1386494 between ODD and control groups. Haplotype analyses revealed higher frequencies of haplotypes TA (rs4570625-rs11178997), TAG (rs4570625-rs11178997-rs1386494), TAA (rs4570625-rs11178997-rs7305115) and TAGA (rs4570625-rs11178997-rs1386494-rs7305115), but lower frequencies of haplotypes GA (rs4570625-rs11178997) and GAG (rs4570625-rs11178997-rs1386494) in ODD compared to control groups. CONCLUSIONS: These findings suggest the role of these TPH-2 gene variants in susceptibility to ODD. Some haplotypes might be the risk factors for Chinese Han children with ODD, while others might be preventable factors.
