Some problems with cyberbullying research
An item response theory analysis of the Olweus Bullying scale
In the present article, we used IRT (graded response) modeling as a useful technology for a detailed and refined study of the psychometric properties of the various items of the Olweus Bullying scale and the scale itself. The sample consisted of a very large number of Norwegian 4th-10th grade students (n = 48 926). The IRT analyses revealed that the scale was essentially unidimensional and had excellent reliability in the upper ranges of the late…
School Bullying
After sketching how my own interest and research into bullying problems began, I address a number of potentially controversial issues related to the definition and measurement of such problems. The importance of maintaining the distinctions between bullying victimization and general victimization and between bullying perpetration and general aggression is strongly emphasized. There are particular problems with the common method of peer nomination…
Cyberbullying
The paper argues that several claims about cyberbullying made in the media and elsewhere are greatly exaggerated and have little empirical scientific support. Contradicting these claims, it turns out that cyberbullying, when studied in proper context, is a low-prevalence phenomenon, which has not increased over time and has not created many “new” victims and bullies, that is, children and youth who are not also involved in some form of traditiona…
Bullying in school
The nature and extent of bullying among school children is discussed, and recent attention to the phenomenon by researchers, the media, and policy makers is noted. The Olweus Bullying Prevention Program (OBPP) is a comprehensive, school-wide program that was designed to reduce bullying and achieve better peer relations among students in elementary, middle, and junior high school grades. Several large-scale studies from Norway are reviewed, which …
Does the Quality of Parent–Child Relationships Mediate the Increased Risk for Antisocial Behavior and Substance Use Among Adolescents in Single-Mother and Single-Father Families
This study focuses on how specific parent–child relationship variables may function as mediators of the association between two postdivorce family structures and antisocial behavior and substance use. Five parent–child relationship variables (mother/father–child conflict, parental monitoring, and mother/father–child closeness) were tested as potential mediators of the relationship between living in a single-mother or single-father household and t…
Bullies and victims at school
Background. The reported prevalence of bully-victims and aggressive/provocative victims varies quite considerably in previous research, and only a few studies have reported prevalence rates across grades. There is also a lack of detailed analyses of the extent to which victims are also bullies, and bullies are also victims.Aims. To study the prevalence of male and female bully-victims across grade/age and to establish the degree of overlap or rel…
Adolescent's Adjustment in Four Post-Divorce Family Structures
Using a theoretically guided contrast analysis approach (see Furr & Rosenthal, 2003; Rosnow & Rosenthal, 2002) and data from a relatively large community sample (2550 students in grades 7-9), different sets of hypotheses dealing with adolescents' adjustment in four post-divorce family structures were tested. Most of the hypotheses matched with the data. Adolescents from single mother and stepfather families were at a moderately increased risk of …
Prevalence estimation of school bullying with the Olweus Bully/Victim Questionnaire
The key aim of the present research was to study the “functionality” of two global variables in the Olweus Bully/Victim Questionnaire and to examine the appropriateness of different cutoff points of these variables for prevalence estimation. Several empirical and conceptual analyses strongly attested to the functionality of the two selected variables in terms of construct validity and selected measurement properties. Similarly, a number of analys…
The Importance of Sex‐of‐Stimulus Object
The main goals of the study were to examine age trends and sex differences in empathic responsiveness, particularly empathic concern for others in distress. It was based on four cohorts of Norwegian students aged 13 to 16, comprising a total of 1193 boys and 1093 girls. The key measurement instrument was a partly new questionnaire on empathic responsiveness in which sets of items were differentiated according to sex‐of‐stimulus object. The empiri…

Stability of Global Self-Evaluations in Early Adolescence
This study is mainly concerned with the stability (i.e., relative longitudinal consistency) of individual differences in global self-esteem in early adolescence. In the first part, stability data from a large cohort longitudinal study were presented. Approximately 2,400 subjects were followed over 2 1/2 years, yielding a total of 4.2 stability coefficients. These coefficients were then compared with 21 stability coefficients from previously publi…
Circulating testosterone levels and aggression in adolescent males
Empirical analyses conducted within a causal-analytic framework (path analysis) on a sample of normal adolescent human males suggested that circulating levels of testosterone in the blood had a direct causal influence on provoked aggressive behavior (self-reports): A high level of testosterone led to an increased readiness to respond vigorously and assertively to provocations and threats. Testosterone also had an indirect and weaker affect on ano…
Assessment of Global Negative Self-Evaluations and Perceived Stability of Self in Norwegian Preadolescents and Adolescents
A special problem in the study of self-esteem is the use of quite different instruments for subjects at different age levels. In the present paper the primary goal was to construct a scale that could be used to assess global self-evaluations in children as well as in adolescents and adults. The scale presented (GSE) based mainly on Rosenberg's Self-Esteem Scale (RSE) was used in this study with 2478 children aged 10 to 15 years. A second goal was…
Applicability of olweu' aggression inventory in a sample of chinese primary school children
A sample of Chinese children in Grade 4 (155 boys and 135 girls with an average age of 10.3 years) completed Olweu' Aggression Inventory, an instrument developed for the assessment of aggressive and aggression controlling behavior tendencies in a Western culture. Results indicated that the questionnaire gave quite meaningful information when used with the Chinese children. Two interpretable factors, general aggression and aggression control, were…
Development of Antisocial and Prosocial Behavior (Developmental Psychology)
Testosterone, Aggression, Physical, and Personality Dimensions in Normal Adolescent Males
Fifty-eight normal adolescent Swedish boys, aged 16, provided two sets of blood samples for plasma testosterone assays as well as data on a number of personality inventories and rating scales assessing aggression, inpulsiveness, lack of frustration tolerance, extraversion, and anxiety. Physical variables such as pubertal stage, height, weight, chest circumference, and physical strength were measured. There was a significant association (r = 0.44)…
Familial and temperamental determinants of aggressive behavior in adolescent boys
Stability of aggressive reaction patterns in males
Stability of aggressive reaction patterns in males
Considered in the review are 16 studies on the stability of aggressive behavior and reaction patterns. There is great variation among the studies in sample composition, in definition of variables, in method of data collection, and in the ages and intervals studied. Generally, the size of a (disattenuated) stability coefficient tends to decrease linearly as the interval between the two times of measurement (T2 — 7\\) increases. Furthermore, the de…
