Testing the developmental distinctiveness of male proactive and reactive aggression with a nested longitudinal experimental intervention

An experimental preventive intervention nested into a longitudinal study was used to test the developmental distinctiveness of proactive and reactive aggression. The randomized multimodal preventive intervention targeted a subsample of boys rated disruptive by their teachers. These boys were initially part of a sample of 895 boys, followed from kindergarten to 17 years of age. Semiparametric analyses of developmental trajectories for self‐reported proactive and reactive aggression (between 13 and 17 years of age) indicated three trajectories for each type of aggression that varied in size and shape (Low, Moderate, and High Peaking). Intent‐to‐treat comparisons between the boys in the prevention group and the control group confirmed that the preventive intervention between 7 and 9 years of age, which included parenting skills and social skills training, could impact the development of reactive more than proactive aggression. The intervention effect identified in reactive aggression was related to a reduction in self‐reported coercive parenting. The importance of these results for the distinction between subtypes of aggressive behaviors and the value of longitudinal‐experimental studies from early childhood onward is discussed. Aggr.

Parental media monitoring,prosocial violent media exposure,and adolescents' prosocial and aggressive behaviors

Prosocial violent media (e.g., media that combines both violent and prosocial content) is especially popular in entertainment media today. However, it remains unclear how parental media monitoring is associated with exposure to prosocial violent content and adolescent behavior. Accordingly, 1,193 adolescents were asked about parental media monitoring, media content exposure, and behavior. Main findings suggest that autonomy supportive restrictive monitoring was associated with lower levels of exposure to prosocial violent content, but only among older adolescents. Additionally, autonomy supportive restrictive monitoring was the only form of parental media monitoring associated with lower levels of violent content and higher levels of prosocial content, and autonomy supportive active monitoring was the only parental monitoring strategy that promoted prosocial behavior via exposure to prosocial media content. Discussion focuses on the importance of autonomy supportive parental monitoring, as well as the implications of parents encouraging their children to watch media with limited violent content—even if it is prosocial violent content.     

医调委:功能冲突与制度调适

为了回应日益严峻的医患冲突, 医患纠纷人民调解委员会 (简称"医调委") 这一专业性调解组织在全国范围内被广泛地组建起来。研究表明医调委既要维护医疗场所秩序稳定, 又要满足患方权利诉求, 同时还需要保护医疗机构的合法权益, 在很多时候, 这些功能需求存在尖锐的冲突。虽然医调委发展出一些制度性策略来缓和这些功能冲突, 但是效果有限。医调委的长远发展在很大程度上受制于医疗诉讼, 为医调委的长远发展考虑, 需要从理论上进一步思考其组织定位。     

真实型领导对教师知识分享行为的影响:组织支持感的中介和调节作用*

为了探讨真实型领导、组织支持感和教师知识分享行为的关系,对330个有效教师样本进行研究。结果发现:(1)真实型领导对教师的知识分享行为具有显著的预测作用(β=0.494,p<0.001)。(2)组织支持感在两者之间具有部分中介作用,间接效应占总效应的44.8%。(3)组织支持感在真实型领导的下属导向、领导特质、诚实不欺和正直无私与知识分享行为的关系中起调节作用,但在循规蹈矩与知识分享行为的关系中的调节作用不显著。     

The Role of Parental Mediation and Peer Norms on the Likelihood of Cyberbullying

ABSTRACT

Cyberbullying is a disturbing behavior associated with the use of communication technologies among adolescents. Many studies have been devoted to the activities of cyber victims as risk factors, while others have considered parental mediation a protective factor. However, there is a paucity of studies investigating the joint contribution of parental mediation, peer norms and risky online activities to the likelihood of being bullied on the Internet. To fill this gap, we conducted a study among a representative sample of 495 sixth to eleventh grade adolescents. We measured risky behavior online with items indicating the frequency of posting personal details, sending an insulting message and meeting face-to-face with a stranger met online. Respondents reported their perceptions about their peers. attitudes toward these risky online behaviors. We also measured three types of parental mediation: active guidance, restrictive supervision and non-intervention. Binary logistic regression findings show that risky online behaviors and peer norms regarding these behaviors had a significant effect, suggesting that the likelihood of being bullied on the Internet is associated with both risky behavior online and the norms prevalent within the adolescents. peer group. Restrictive supervision had a significant effect, implying that parents who feel their children are being bullied online may increase their oversight. The results emphasize the critical role of peers and the declining influence of parents in adolescence.     

相对剥夺感与社会适应方式：中介效应和调节效应

以6175名17岁以上的个体为被试, 采用四种自编问卷考察了相对剥夺感对创新和反叛这两种社会适应方式的影响, 归因方式在其中的中介作用和调节作用, 同时还考察了反叛在相对剥夺感和创新关系中的调节作用。结果发现：①相对剥夺感对创新和反叛具有正向预测作用, 相对剥夺感越高, 创新和反叛的程度越强烈; ②归因方式对相对剥夺感和创新的关系起部分中介作用, 对相对剥夺感和反叛的关系起部分中介作用; ③归因方式在相对剥夺感和反叛的关系中起调节作用, 能增强相对剥夺感和反叛之间的关系; ④在下层阶层中, 反叛在相对剥夺感和创新的关系中起调节作用, 能减弱相对剥夺感和创新之间的关系。综上所述可以认为, 相对剥夺感对社会适应方式具有正向预测作用; 归因方式对相对剥夺感与社会适应方式的关系起部分中介作用; 在弱势群体阶层中, 反叛能减弱相对剥夺感对创新的直接影响。     

Resisting temptation: alcohol specific self-efficacy mediates the impacts of compensatory health beliefs and behaviours on alcohol consumption

Awareness of health risks linked with excessive alcohol consumption appears to have little influence on how much some people drink. Compensatory health beliefs (CHBs), in which the consequences of unhealthy behaviour are considered to be neutralised by additional healthy behaviours, are one way of justifying poor health choices. Currently, the role of CHBs within the context of drinking behaviour is not well understood. This research examined associations between alcohol specific compensatory health beliefs (ACH-Beliefs) and behaviours (ACH-Behaviours), alcohol consumption and alcohol specific self-efficacy (ASE), via an online survey completed by 249 participants, aged 18 + years (63.1% female; M age = 41.62 years; SD = 14.80). Higher ACH-Beliefs were associated with increases in ACH-Behaviours. While both predicted alcohol consumption, a greater proportion of variance was explained by ACH-Behaviours. ASE was a significant mediator of those relationships, suggesting that those with higher ASE may be better equipped to regulate drinking behaviour. Recommendations for future research include measuring both CHBs and behaviours within an experimental design, and further investigation of related cognitions such as compensatory behaviour intentions. Alcohol misuse interventions may wish to consider the potential roles of CHBs and behaviours in facilitating maladaptive coping strategies, and how addressing these may reduce harms.     

Psychosocial health mediates the gratitude-physical health link

There is now a growing body of research demonstrating the physical health benefits of being grateful. However, research has only just began to explore the mechanisms accounting for this gratitude-health relationship. This study examines the relationship between dispositional gratitude and self-reported physical health symptoms, and explores whether this relationship is explained through reduced levels of perceived loneliness and stress. This study employed a cross-sectional design with a sample of 607 healthy adults. Serial mediation analysis revealed that the positive effect of gratitude on physical health was significantly mediated by lower reported levels of perceived loneliness and stress. These findings are important given evidence that gratitude can be cultivated, and may serve to buffer against stress and loneliness and improve somatic health symptoms in the general population.
