Reading problems and depressed mood

Although reading difficulties show well-established overlaps with disruptive behavior disorders in childhood, much less is known about reading-disabled children's vulnerability to emotional difficulties. Using longitudinal data from 6 assessments of boys in the Pittsburgh Youth Study, we found robust links between severe, persistent reading problems and increased risk for depressed mood in a community sample of boys aged 7 and 10 years at initial assessment, though not in those who had already entered their teens. These associations could not be accounted for in terms of selected family risks or comorbid disruptive behaviors; instead, the pattern of the findings pointed to the existence of more direct causal processes whereby reading problems influence younger boys' risk of depressed mood.     

School Context and Genetic Influences on Aggression in Adolescence

Genetic and environmental contributions to variation in aggression were examined using adolescents' self-reports of aggressive behavior. The National Longitudinal Study of Adolescent Health provided a sample of 1,515 pairs of adolescents in five genetically informative groups (i.e., monozygotic twins, dizygotic twins, full siblings, half siblings, and unrelated siblings reared together). The analysis, a DeFries-Fulker regression within a hierarchical linear model, yielded findings on individual-level heritability (h2), shared environmental effects (c2), school-level effects, and school-level moderation of h2 and c2. The estimate of h2 for aggression in the full sample was .32, and c2 was .05. In the moderating effect, h2 increased and c2 decreased with greater school-level family warmth. Two effects on school means were found: Those schools with greater ethnic-racial heterogeneity had higher mean levels of aggression, and schools where students perceived greater family warmth had lower mean levels of aggression.     

Genetic and environmental influences on the relationships between family connectedness, school connectedness, and adolescent depressed mood: sex differences.

This study investigated (a) genetic and environmental contributions to the relationship between family and school environment and depressed mood and (b) potential sex differences in genetic and environmental contributions to both variation in and covariation between family connectedness, school connectedness, and adolescent depressed mood. Data are from 2,302 adolescent sibling pairs (mean age = 16 years) who were part of the National Longitudinal Study of Adolescent Health. Although genetic factors appeared to be important overall, model-fitting analyses revealed that the best-fitting model was a model that allowed for different parameters for male and female adolescents. Genetic contributions to variation in all 3 variables were greater among female adolescents than male adolescents, especially for depressed mood. Genetic factors also contributed to the correlations between family and school environment and adolescent depressed mood, although, again, these factors were stronger for female than for male adolescents.     

A suicidal adolescent's sleeping beauty syndrome: cessation orientations toward dying, sleep, and drugs

In a study of hospitalized suicidal youth, the account of a sixteen-year-old girl, diagnosed as schizophrenic, is analyzed to gain insight into a family's role in the suicidal career of an adolescent preoccupied with death and dying, sleep, and drugs; the interplay of her construction of reality with her risk-taking, self-injurious way of life; and her perceived problems of living and need for help. Her cessation orientations revealed a kind of Sleeping Beauty syndrome with fantasies on sleep, drugs, and death, including a death of the mind from overdosing. Such qualitative research on suicidal careers may increase our understanding of the at-risk adolescent population and assist in the development of a policy for identifying and meeting needs and following up on clues for prevention and early intervention.     

Bobo clown aggression in childhood: Environment,not genes

We videotaped 216 twin children (average age: 7.6 years) hitting a 5-ft “Bobo clown”. Three behaviors in the Bobo clown situation showed adequate response characteristics, rater reliability, and test-retest reliability: number of hits, intensity of hits, and number of quadrants (into which the Bobo clown was hit). In terms of two “anchor” variables, height and weight, the twin correlations were representative of other studies in suggesting substantial hereditary influence. However, twin analyses of the three behavioral ratings during the Bobo clown session yielded no evidence of hereditary influence. Moreover, the results provided evidence of substantial environmental influence of the “between-family” variety. In other words, the family environment is the major source of individual differences for these measures.     

Traiter ses données proprement : vers un meilleur usage du data cleaning

Data cleaning has long been shown to be an essential step in data analysis but its application is not systematic and varies between researchers. The aim of the present article is to study the effect of the different elements of data cleaning and to give recommendations. The steps considered are normality, outliers and missing values. Firstly, we advise a close examination of the data and its normality with a view to transformation. Secondly, we look at outliers and their treatment (trimming and winsorizing). Lastly, we turn our attention to missing values and how to deal with them depending on their randomness. We also cover the importance of visualizing data before analysis. Finally, we illustrate the effect of these data cleaning practices on a real data set. We show that data cleaning can lead to a significant result becoming non-significant and therefore demonstrate the importance of these steps before starting data analysis.     

Attachment style differences in the processing of attachment–relevant information: Primed–style effects on recall,interpersonal expectations,and affect

The present study explored processing biases resulting from manipulating the temporal accessibility of relational schemas. By priming relational schemas, relationship–specific attachment styles were activated and their biasing effect on relevant information processing (namely recall for attachment–relevant words versus other words, interpersonal expectations, and affect) was examined. It was found that participants primed with a secure–style relational schema recalled more positive attachment words than those primed with an avoidant style. Although pre–priming endorsements of interpersonal expectations were influenced by global attachment style, once primed, participants showed primed–style–congruent responses. That is, primed secures showed higher endorsement of positive and lower endorsement of negative interpersonal expectations relative to the other primed style groups. Finally, primed secures reported more positive and less negative affect than the other primed style groups. Implications for understanding the way differential attachment experiences influence close relationships through life are considered.     

The Influence of Videoconference Technology and Interview Structure on the Recruiting Function of the Employment Interview: A Field Experiment

This field experiment examined whether interview medium and interview structure affects the attractiveness of organizations, interviewer friendliness and performance. Attractiveness ratings of 25 organizations were provided by 92 real job applicants, assigned to either a face–to–face (FTF) or a videoconference (VC) interview. An interview medium X structure interaction showed FTF applicants were attracted most to organizations who conducted their interviews with less structure, while VC applicants were more attracted to organizations using structured interviews. Interview structure had no effect on applicants’ perception of the interviewer’s performance; however, interviewers’ performance was rated higher for FTF than VC interviews. Applicants were more satisfied with their FTF performance in less structured interviews and more satisfied with their VC performance in highly structured interviews.     

蒙汉族大学生父母教养方式、成人依恋与心理困扰的关系研究

通过整群抽样方法抽取了576名大学生,对其施测父母养育方式量表、亲密关系体验量表和心理困扰量表,运用结构方程模型技术,分别考察了父母养育方式的蒙汉族差异以及成人依恋模式在父母养育方式和心理困扰间的中介作用。结果表明:(1) 蒙古族父母对孩子的关爱程度和给孩子的自主性要显著高于汉族;(2) 汉族的成人依恋模式在父母过度保护与抑郁-焦虑-压力之间起着部分中介作用,而蒙古族成人依恋的中介作用不明显,但母亲的冷漠拒绝和过度保护会导致个体依恋回避和依恋焦虑,父亲的冷漠拒绝和过度保护会影响个体的抑郁和焦虑,母亲的过度保护和父亲的冷漠拒绝会影响个体的压力。
