Parenting behaviors have long been recognized as crucial to children's healthy development. However, examinations of the etiology of these behaviors are less prevalent. The current study investigated the driving forces behind parental warmth and discipline, particularly whether they are related more to traits within the parent or reactions to characteristics of the child.

The goal of the present study was to examine genetic and familial influences on self-perception and self-esteem in separate samples of children (153 twin pairs of 5-year-olds) and adults (753 twin pairs between the ages of 25-75 years). Genetic common factor modeling showed that three facets of self-perception (physical competence, peer acceptance, and maternal acceptance) loaded onto a single heritable factor in children.

The current project used a longitudinal design to examine how individual vulnerability for externalizing behavior is influenced by the interplay among biological/genetic and environmental factors, and how this occurs across development. We investigated the influence of dopamine receptor D4 genotype (DRD4), child temperament, and household chaos on children's externalizing behaviors using a sample of twins/triplets tested at the ages of 4 and 5 years (n = 229), including a subset of these who were tested again in middle childhood (ages 7-13 years; n = 174).

A number of specialties have incorporated or required simulation-based educational techniques in residency education over the past 10 years, but little is known about the current use of SBME in family medicine graduate medical education. We also evaluated associations between program characteristics and the use of SBME in FMR education.

In human beings, variations in pubertal timing have not been systematically examined in relation to social environmental antecedents, although their psychological consequences are well documented. This paper focuses on links in human beings between pubertal timing and the childhood social environment, with several sections: A review of studies relating pubertal timing to the family context, a key aspect of the social environment; challenges in studying the issue; and opportunities for future work that takes advantage of and creates links with evidence in other species.

Specifically, we examined prediction of externalizing behaviors from birth complications and negative emotionality, each moderated by genetic risk for aggression and ecological risk factors of insensitive parenting and low family income. At ages 4 and 5 years, 170 twin pairs and 5 triplet sets (N = 355 children) were tested; 166 of those children were tested again at middle childhood (M = 7.

Parenting practices have been shown to be related to self-esteem, but these estimates are confounded because parents and children share genes. The aim of the present study was to use the monozygotic (MZ) twin difference design to isolate the non-shared environmental impact of remembered parenting on self-esteem.

Background: Although learning environment (LE) is an important component of medical training, there are few instruments to investigate LE in Latin American and Brazilian medical schools. Therefore, this study aims to translate, adapt transculturally, and validate the Medical School Learning Environment Scale (MSLES) and the Johns Hopkins Learning Environment Scale (JHLES) to the Brazilian Portuguese language.
Method: This study was carried out between June 2016 and October 2017.
Pubertal timing matters for psychological development. Early maturation in girls is linked to risk for depression and externalizing problems in adolescence and possibly adulthood, and early and late maturation in boys are linked to depression. It is unclear whether pubertal timing uniquely predicts problems; it might instead mediate the continuity of behavior problems from childhood to adolescence or create psychological risk specifically in youth with existing problems, thus moderating the link.

Objective: We sought to understand the landscape of published articles regarding medical schools' learning environments (LE) worldwide, with an explicit focus on potentially harmful aspects of the LE as an effort to identify areas specifically in need of remediation or intervention that could prevent future unprofessional behaviors, burnout, violence and mistreatment among students and physicians.
Methods: A bibliometric analysis was conducted in six electronic databases (PubMed/Medline, Web of Science, Cochrane Library, SCOPUS, ERIC-ProQuest, and PsycINFO) up to December 31, 2016, including 12 themes: learning environment - general, hidden curriculum (harmful), unethical behaviors, bullying/hazing, violence, sexual discrimination, homophobia, racism, social discrimination, minorities discrimination, professional misconduct, and other negative aspects.
Results: Of the 9,338 articles found, 710 met the inclusion criteria.
Physical and mental health problems are becoming more common among the general population. Studies examining mental and physical health often indicate that mental illness early in life is associated with more detrimental health outcomes later. However, additional work is needed to better identity which psychological problems may contribute to poorer health outcomes.

Play among peers is an important developmental context for child socialization. We have earlier shown that children at genetic risk for aggression were more likely to be treated aggressively by unfamiliar peers during peer play, reflecting genotype-evoked behaviors manifested during play. In this study, 118 5-year-old twin pairs were paired randomly with an unfamiliar, same-age, same-sex child, thus controlling for parent- and child-chosen environments (passive and active rGE).

: The Empathy, Spirituality, and Wellness in Medicine Scale (ESWIM) is a 43-item multidimensional scale developed to investigate different dimensions of physicians and medical students. : Medical education research requires the use of several different instruments with dozens of items that evaluate each construct separately, making their application slow and increasing the likelihood of students providing a large number of incomplete or missing responses. To provide an alternative measure, this study aims to translate, adapt, and validate the multidimensional ESWIM instrument for Brazilian medical students.

Methods: This cross-cultural study included students enrolled in the first and second years of their undergraduate medical training. We evaluated depression, anxiety, and stress (DASS 21), empathy, openness to spirituality, and wellness (ESWIM), burnout (Oldenburg), and quality of life (WHOQOL-Bref) and compared them between schools.
Negotiations are inherently dyadic. Negotiators' individual-level characteristics may not only make them perform better or worse in general, but also may make them particularly well- or poorly-suited to negotiate with a particular counterpart. The present research estimates the extent to which performance in a distributive negotiation is affected by (a) the negotiators' individual-level characteristics and (b) dyadic interaction effects that are defined by the unique pairings between the negotiators and their counterparts.

Many psychiatric disorders are caused by multiple genes and multiple environmental factors, making the identification of specific genetic risk factors for these disorders difficult. Endophenotypes are behaviors or characteristics that are intermediate between the genotype and a phenotype of interest. Because they are more directly related to the gene action than is the endpoint disorder, they may be useful in the identification of specific genes related to psychiatric disorders and the classification of disorders or traits that share an underlying genetic etiology.
View Article and Find Full Text PDFTheory: Empathy is one component of medical student education that may be important to nurture, but there are many potential psychological barriers to empathy, such as student depression, burnout, and low quality of life or wellness behaviors. However, few studies have addressed how positive behaviors such as wellness and spirituality, in combination with these barriers, might affect empathy.
Hypotheses: We hypothesized a negative relationship between psychological distress and empathy, and a positive relationship between empathy and wellness behaviors.
The development of prosocial behaviors during the preschool years is essential for children's positive interactions with peers in school and other social situations. Although there is some evidence of genetic influences on prosocial behaviors, very little is known about how genes and environment, independently and in concert, affect prosocial behaviors in young children. This study of 126 twin and sibling pairs examined 5-year-old preschool children's positive behaviors (prosocial and easy-going) while playing freely with an unfamiliar, same-age, same-sex peer.
