Temperament and common disruptive behavior problems in preschool

The study evaluated trait associations with common Disruptive Behavior Disorders (DBD), Oppositional Defiant Disorder (ODD) and Attention-Deficit/Hyperactivity Disorder (ADHD), during an understudied developmental period: preschool. Participants were 109 children ages 3–6 and their families. DBD symptoms were available via parent and teacher/caregiver report on the Disruptive Behavior Rating Scale. Traits were measured using observational coding paradigms, and parent and examiner report on the Child Behavior Questionnaire and the California Q-Sort. The DBD groups exhibited significantly higher negative affect, higher surgency, and lower effortful control. Negative affect was associated with most DBD symptom domains; surgency and reactive control were associated with hyperactivity-impulsivity; and effortful control was associated with ADHD and inattention. Interactive effects between effortful control and negative affect and curvilinear associations of reactive control with DBD symptoms were evident. Temperament trait associations with DBD during preschool are similar to those seen during middle childhood. Extreme levels of temperament traits are associated with DBD as early as preschool.     

Ethical care for infants with conditions not curable with intensive care

Offering intensive care to neonates who have conditions that carry extremely poor prognoses is a source of great contention amongst neonatologists. The concept of best interests is commonly used as a rationale for refusing such care, despite the fact that parents of these infants often have a different view of what best interests means. This article takes up the question of what best interests should incorporate for infants with lethal conditions not curable with intensive care, and how and who should decide which treatment options should be implemented. Based on our recommendation that parents be apprised of the basis upon which physicians are evaluating treatment options, we offer a framework that allows all relevant parties to approach the issue of what is appropriate treatment from a similar place. We maintain that this approach will increase transparency, dialogue, understanding, and trust, which, in turn, may result in greater consensus.     

Aping expressions? Chimpanzees produce distinct laugh types when responding to laughter of others

Humans have the ability to replicate the emotional expressions of others even when they undergo different emotions. Such distinct responses of expressions, especially positive expressions, play a central role in everyday social communication of humans and may give the responding individuals important advantages in cooperation and communication. The present work examined laughter in chimpanzees to test whether nonhuman primates also use their expressions in such distinct ways. The approach was first to examine the form and occurrence of laugh replications (laughter after the laughter of others) and spontaneous laughter of chimpanzees during social play and then to test whether their laugh replications represented laugh-elicited laugh responses (laughter triggered by the laughter of others) by using a quantitative method designed to measure responses in natural social settings. The results of this study indicated that chimpanzees produce laugh-elicited laughter that is distinct in form and occurrence from their spontaneous laughter. These findings provide the first empirical evidence that nonhuman primates have the ability to replicate the expressions of others by producing expressions that differ in their underlying emotions and social implications. The data further showed that the laugh-elicited laugh responses of the subjects were closely linked to play maintenance, suggesting that chimpanzees might gain important cooperative and communicative advantages by responding with laughter to the laughter of their social partners. Notably, some chimpanzee groups of this study responded more with laughter than others, an outcome that provides empirical support of a socialization of expressions in great apes similar to that of humans.     

Prenatal testosterone and preschool Disruptive Behavior Disorders

Disruptive Behavior Disorders (DBD), including Oppositional-Defiant Disorder (ODD) and Attention-Deficit/Hyperactivity Disorder (ADHD), are fairly common and highly impairing childhood behavior disorders that can be diagnosed as early as preschool. Prenatal exposure to testosterone may be particularly relevant to these early-emerging DBDs that exhibit a sex-biased prevalence rate favoring males. The current study examined associations between preschool DBD symptom domains and prenatal exposure to testosterone measured indirectly via right 2D:4D finger-length ratios. The study sample consisted of 109 preschool-age children between ages 3 and 6 (64% males; 72% with DBD) and their primary caregivers. Primary caregivers completed a semi-structured interview (i.e., Kiddie Disruptive Behavior Disorder Schedule), as well as symptom questionnaires (i.e., Disruptive Behavior Rating Scale, Peer Conflict Scale); teachers and/or daycare providers completed symptom questionnaires and children provided measures of prenatal testosterone exposure, measured indirectly via finger-length ratios (i.e., right 2D:4D). Study results indicated a significant association of high prenatal testosterone (i.e., smaller right 2D:4D) with high hyperactive–impulsive ADHD symptoms in girls but not boys, suggesting that the effect may be driven by, or might only exist in, girls. The present study suggests that prenatal exposure to testosterone may increase risk for early ADHD, particularly hyperactivity–impulsivity, in preschool girls.     

The structure of childhood disruptive behaviors

Attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) frequently co-occur. Comorbidity of these 2 childhood disruptive behavior domains has not been satisfactorily explained at either a structural or etiological level. The current study evaluated a bifactor model, which allows for a "g" factor in addition to distinct component factors, in relation to other models to improve understanding of the structural relationship between ADHD and ODD. Participants were 548 children (321 boys, 227 girls) between the ages of 6 years and 18 years who participated in a comprehensive diagnostic assessment incorporating parent and teacher ratings of symptoms. Of these 548 children, 153 children were diagnosed with ADHD (without ODD), 114 children were diagnosed with ADHD + ODD, 26 children were diagnosed with ODD (without ADHD), and 239 children were classified as non-ADHD/ODD comparison children (including subthreshold cases). ADHD symptoms were assessed via parent report on a diagnostic interview and via parent and teacher report on the ADHD Rating Scale. ODD symptoms were assessed via teacher report. A bifactor model of disruptive behavior, comprising a "g" factor and the specific factors of ADHD and ODD, exhibited best fit, compared to 1-factor, 2-factor, 3-factor, and 2nd-order factor models of disruptive behaviors. It is concluded that a bifactor model of childhood disruptive behaviors is superior to existing models and may help explain common patterns of comorbidity between ADHD and ODD.     

External Validation of Bifactor Model of ADHD: Explaining Heterogeneity in Psychiatric Comorbidity,Cognitive Control,and Personality Trait Profiles Within DSM-IV ADHD

The current paper provides external validation of the bifactor model of ADHD by examining associations between ADHD latent factor/profile scores and external validation indices. 548 children (321 boys; 302 with ADHD), 6 to 18 years old, recruited from the community participated in a comprehensive diagnostic procedure. Mothers completed the Child Behavior Checklist, Early Adolescent Temperament Questionnaire, and California Q-Sort. Children completed the Stop and Trail-Making Task. Specific inattention was associated with depression/withdrawal, slower cognitive task performance, introversion, agreeableness, and high reactive control; specific hyperactivity-impulsivity was associated with rule-breaking/aggressive behavior, social problems, errors during set-shifting, extraversion, disagreeableness, and low reactive control. It is concluded that the bifactor model provides better explanation of heterogeneity within ADHD than DSM-IV ADHD symptom counts or subtypes.     

Social Deviance Theories: Can They Explain Rural Vandalism in the Twenty-First Century?

Rural crime is a heavily misunderstood and marginalized area of criminology. In the United Kingdom in particular, there is limited scholarship on the issue and even less on particular types of rural crime, such as rural vandalism. With this in mind, this article reviews the applicability of five deviance theories to several forms of rural vandalism, through a less traditional lens that challenges criminological and rural norms. The article concludes by arguing that most of the theories examined are relevant to explanations of rural vandalism. However, it also emphasizes the need for a solid definition of rural crime, and an overall move away from the urban focus of criminology.     

Incapable sex: a case study

Although it is well known that intimacy and sexual expression are an important part of being human and of healthy living, facilities such as nursing homes, adult group homes, or assisted living residences commonly struggle with knowing how to balance supporting residents who are incapable to have sexual lives with their duty to protect them from foreseeable harm. This article presents a challenging case and uses the British Columbia Supporting Sexual Health and Intimacy in Care Facility Guidelines to determine what should be done.     

Do social comparisons in academic settings relate to gender and academic self-confidence?

This paper reports the development of an Academic Social Comparison Scale (ASCS) to measure students’ tendencies to socially compare themselves with other students in an educational setting. The 27-item ASCS was then measured in relation to academic self-confidence in a sample of University students, using the Individual Learning Profile (ILP) scale. The study found that making downward academic social comparisons was not very commonly reported and did not relate to academic confidence in any domain measured. Confidence in numeracy, speaking, and hard IT were, however, significantly lower in those students who tended to make more upward social comparisons. The results also showed that the less students reported that they socially compared in general, the more confident they were in reading, writing, and time management. All three subscales of the ASCS showed good reliability when tested 6–9 weeks later. The ASCS showed that female students tended to make more upward academic social comparisons and less downward academic comparisons than male students. In domains such as reading and writing people’s confidence was higher if they made fewer academic social comparisons (irrespective of direction), and gender was not an important factor. Results also showed that academic confidence was neither higher nor lower in students who reported making more downwards academic comparisons. This study demonstrates the negative impact on confidence of upward social comparisons, and introduces a social comparison questionnaire specifically tailored for measuring people’s tendencies to make social comparisons in the academic domain.
