概括
多基因分数 (PGSs) 预测了童年受害,教育程度是一个强有力的预测因素. 调查结果因告密者而异,突出显示了多个观点在理解与受害的遗传联系方面的重要性.
科学领域:
- 发展心理学 发展心理学
- 行为遗传学 行为遗传学
- 儿童精神病学 儿童精神病学
背景情况:
- 同龄人受害在童年和青春期很常见,具有潜在的长期影响.
- 之前关于受害者的遗传脆弱性 (多基因分数,PGS) 的研究依赖于自我报告,并没有检查随时间变化的情况.
研究的目的:
- 通过使用多个信息人 (教师,同龄人,自我报告) 在不同发展阶段调查PGS和受害者之间的关联.
- 探索PGS是否预测了从童年到青春期的受害轨迹.
主要方法:
- 利用了北克新生儿双胞胎研究 (n=536) 的数据.
- 通过自我报告 (7-17岁) 和教师/同行报告 (7-10岁) 评估了受害者状况.
- 通过回归和增长曲线模型,检查了10个心理健康,认知和身体特征的PGS作为预测因素.
主要成果:
- 预测受害者的PGS在所有线人之间是一致的,但效果大小不同.
- 心理健康PGS预测了自我报告的受害者;认知/身体特征PGS预测了教师/同行报告的受害者.
- 教育成就的PGS显示了所有告密者中与受害的最强的负面关联;没有PGS预测了随时间的变化受害的变化.
结论:
- 教育成绩的多基因分数是受害者的强有力的预测指标.
- 告知者的选择显著影响了PGS和受害者之间的观察到的关联.
- 使用多个告密者加强了调查结果,并提供了对受害的细微见解.

Bullying
8.4K
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Influence of Parents and Peers on Identity
86
Adolescence is a pivotal period of identity formation, during which individuals begin to answer questions central to their sense of self, such as "Who am I?" and "Who do I hope to become?" Both parents and peers play critical roles in guiding adolescents through this complex developmental phase.

Polygenic Traits
66.0K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Ethnic Identity within a Larger Culture
59
Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

Strategies for Assessing and Addressing Confounding
121
Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

Gene-Environment Interactions
366
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...
