A notable number of adolescents are involved in bullying and different bullying roles have been described in previous research. However, most of the studies used Cross-sectional design, little is known about the stability and the transition of the characters, especially when the students take the transition from elementary school to junior high school. Longitudinal studies are necessary to understand who is expected to bully others or being bullied in the future. The current study used latent class analysis(LPA) to identify subgroups and the transition between the classes across time, and used logistic regression for exploring the features that predicted the transition. Four-wave longitudinal data over 3 years were recruited in Anhui province, 878 students participated both Grade 6 and Grade 7 points were included in this study(68.9% boys). The experience of bullying others and being bullied were assessed in every wave. Findings revealed that:(a) three subgroups were identified among adolescents: aggressor-victim, victim and uninvolved latent classes.(b) adolescents in uninvolved were highly stable, while the other two groups tended to transform to other classes instead of remaining in the origin status.(c) boys, depression and deficiency of mother accompany could predict the transition from the uninvolved group to the victim group. Adolescents with lower peer relation problems and lower depression in the victim group had a higher probability to convert to the aggressor-victim status, while those have lower prosocial behavior and girls tended to transit to the victim group from the aggressor-victim group. The study demonstrated that there were three latent status in adolescents bullying and victimization and different classes were transited across time. Gender, mother working in other cities, depression, peer relationship problems influenced the orientation of the transition.

第六届心理健康学术年会

作者： Yue Zhang Xigeng Zheng Shaofei Jiang zhengkui liu Yunjing Bai CAS Key Laboratory of Mental Health Institute of Psychology Chinese Academy of Sciences Department of Psychology University of Chinese Academy of Sciences

Rationale: Negative affective states, e.g. anhedonia, that emerge after abstinence from drugs of abuse may be linked to the long-lasting motivational processes associated with relapse. Although anhedonia dramatically diminishes over the course of protracted abstinence, it is not yet clear whether, and how,anhedonic states are influenced by stressful events that contribute to craving and relapse. Here we investigated whether the anhedonic behaviors could be elicited by acute stressful events in protracted abstinent rats. Objectives: Male rats were pretreated with a binge-like morphine paradigm for 5 days. The consummatory and motivational responses to sucrose solutions following exposure to acute stress were examined after at least 12 to 16-days of withdrawal from *** presented with sucrose solutions of three concentrations(4%, 15% and 60%), rats were subjected to a 1 h-free consumption test or three operant behavioral tasks with increasing cost/benefit ratio, i.e., fixed ratio 1(FR1), progressive ratio(PR) and PR-punishment(conflict-based) procedure of reinforcement. The consumption and operant respondingunder FR1 and PR procedures were measuredfollowing exposure to acute foot-shock stress(intermittent foot shock, 0.5 mA*0.5 seconds*10 min;mean intershock interval: 40 seconds), and the operant responding for 60% sucrose solution under PR-punishment procedure was measured following a forced-swim stress(5 min).Results: Foot-shock-induced stress mildly decreased consumption of 4% sucrose solution and significantly decreased operant responding for 15% sucrose solution under FR1 procedure, while increased water consumption in rats. The foot-shock stress did not influence operant responding for either sucrose solution under PR procedure. The forced-swim stress suppressed operant responding for 60% sucrose solution under PR-punishment procedure, but had no impact on PR performance for60% sucrose solution. However, the nociception sensitivity in rats was found to

本研究借助网络分析方法,探讨儿童创伤后应激障碍(PTSD)症状的演化规律。以经历汶川地震的197名儿童为研究对象,在灾后4、29、40和52个月对其PTSD症状进行了历时4年的追踪测量。网络分析结果显示,闪回的中心性一直较高,而其他高中心性的症状随时间的推移发生了变化:侵入性想法和创伤线索引发生理性反应的中心性随时间推移呈上升趋势,线索引发情感反应和未来无望的中心性随时间推移呈下降趋势。本研究拓宽了学界对儿童PTSD症状学的认识,并为建立灾后阶段性干预模式提供启示。

为揭示海拔高度与人群抑郁间的关系,研究运用2016~2020中国家庭追踪调查、2015中国健康与养老追踪调查、2016青海玉树成年人身心健康状况调查、《中国城市统计年鉴》等数据,采用多层线性模型、中介模型与流行病学病例对照等方法进行数据分析。结果表明:在控制个体与地区层面因素后,海拔高度与抑郁存在正相关关系;人均GDP与C反应蛋白在海拔高度与抑郁之间发挥中介作用;生活在海拔500~1000、1000~2000及4000~6000米的人群,其抑郁风险分别是生活在500米以下海拔人群的1.53~1.79倍、1.67~2.25倍与9倍左右;生活在500~2000米海拔地区中老年人抑郁风险高于青年人,4000~6000米高海拔地区青年人抑郁风险高于中老年人。综上,研究提示海拔高度是抑郁的危险因素,需高度关注不同海拔地区不同年龄人群的抑郁防范工作。
