The world turns at 33 and 45: Defining simple cutoff scores for the Negative Acts Questionnaire–Revised in a representative sample

Workplace bullying is a serious hazard in every day working life that needs to be assessed carefully. In order to achieve such a goal, both victims of severe bullying as well as targets of less intensive bullying need to be identified, the latter in order to prevent further escalation into severe bullying. Previous research has mainly offered simple and crude measures of who is and who is not a victim of bullying. In this article we show how cutoff scores for the scale Negative Acts Questionnaire–Revised (NAQ-R) can be calculated. Based on a representative sample of the Norwegian workforce, we formulated 2 cutoff points or thresholds for the NAQ-R with a Receiver Operation Characteristic curve. Employees with a score lower than 33 are not bullied, employees with a score between 33 and 45 may be considered as being bullied occasionally, and employees who score above 45 can be considered to be victims of workplace bullying. As the NAQ-R is used in more than 300 research projects worldwide, we hope to inspire other scholars to define similar cutoff points. In addition, we hope that clear cutoff scores may be of assistance to practitioners for designing interventions regarding workplace bullying in line with the identified problems.     

A naturalistic longitudinal evaluation of counselling in primary care

This study evaluated the effectiveness of generic counselling in a primary healthcare setting during three months of counselling and followed up the patients' progress after counselling had finished for the next twenty-one months. Questionnaires were completed by patients within the Dorset Primary Care counselling service on referral to counselling and at set points afterwards. A naturally occurring waiting-list group was compared with patients receiving counselling at baseline and three months. Measurements were taken of patients' psychiatric symptomatology, quality of life (QOL) and self-esteem. Patients who received counselling made highly significant improvements compared with those on the waiting list. These improvements were maintained throughout the long-term follow-up. This would indicate that generic counselling has positive effects that can be maintained for a long period of time after counselling has been completed.     

Boys' and girls' perceptions of parental discipline in transgression situations

Children's perceptions of parental discipline methods and their perceptions of child gender differences in their parents' choices of discipline methods were assessed. One hundred and seventy 8‐year‐old children (78 boys, 92 girls) in two‐parent families were asked about disciplinary behaviour in five transgression situations. The results pointed to gender differences when the children were talking about themselves. Boys believed that they would receive more physical punishment, milder requests and less induction than girls. Children also indicated that their parents would choose a different response if they (themselves) were of the other sex. Both boys and girls reported that their parents would treat boys more severely than they would girls. The results showed that the responses of those children with a sibling of the other sex did not reveal any gender‐differentiated experience of their parents' discipline strategies.

Philosophy of Science: Interfaces between Logic and Knowledge Representation

Abstract

In this inaugural lecture I offer, against the background of a discussion of knowledge representation and its tools, an overview of my research in the philosophy of science. I defend a relational model-theoretic realism as being the appropriate meta-stance most congruent with the model-theoretic view of science as a form of human engagement with the world. Making use of logics with preferential semantics within a model-theoretic paradigm, I give an account of science as process and product. I demonstrate the power of the full-blown employment of this paradigm in the philosophy of science by discussing the main applications of model-theoretic realism to traditional problems in the philosophy of science.

I discuss my views of the nature of logic and of its role in the philosophy of science today. I also specifically offer a brief discussion on the future of cognitive philosophy in South Africa. My conclusion is a general look at the nature of philosophical inquiry and its significance for philosophers today.     

“These Things Took Place as Examples for Us”: On the Theological and Ecumenical Significance of the Lutheran Sola Scriptura

The principle of sola Scriptura does not suggest a reading of the Bible in a room void of context, but points to the fact that the unity of church, canon, and confession defines the identity of the Christian church. The Lutheran Reformation was an attempt to retrieve this perspective at a time when it had become obscure. This retrieval corresponds to certain tendencies on the contemporary scene; it remains to be seen, however, how far convincing answers in this way can be provided for today's burning issues.     

Mothers', fathers' and children's perceptions of parents' expectations about children's family obligations in nine countries

Children's family obligations involve assistance and respect that children are expected to provide to immediate and extended family members and reflect beliefs related to family life that may differ across cultural groups. Mothers, fathers and children (N = 1432 families) in 13 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand and United States) reported on their expectations regarding children's family obligations and parenting attitudes and behaviours. Within families, mothers and fathers had more concordant expectations regarding children's family obligations than did parents and children. Parenting behaviours that were warmer, less neglectful and more controlling as well as parenting attitudes that were more authoritarian were related to higher expectations regarding children's family obligations between families within cultures as well as between cultures. These international findings advance understanding of children's family obligations by contextualising them both within families and across a number of diverse cultural groups in 9 countries.     

A Simple Simulation Technique for Nonnormal Data with Prespecified Skewness,Kurtosis, and Covariance Matrix

We present and investigate a simple way to generate nonnormal data using linear combinations of independent generator (IG) variables. The simulated data have prespecified univariate skewness and kurtosis and a given covariance matrix. In contrast to the widely used Vale-Maurelli (VM) transform, the obtained data are shown to have a non-Gaussian copula. We analytically obtain asymptotic robustness conditions for the IG distribution. We show empirically that popular test statistics in covariance analysis tend to reject true models more often under the IG transform than under the VM transform. This implies that overly optimistic evaluations of estimators and fit statistics in covariance structure analysis may be tempered by including the IG transform for nonnormal data generation. We provide an implementation of the IG transform in the R environment.     

Mental health of outpatient pediatric patients

The purpose of this study is to estimate the percentage of mental health problems in a pediatric outpatient Norwegian clinic. We used the Strengths and Difficulties Questionnaire to screen for mental health problems. Families of children aged 4–11 took part in the study, and 380 out of 982 possible families consented to take part, and 349 families contributed with questionnaire data. The main referral reasons for the patients were asthma, eneuresis and stomach pain. Mothers reported that 17.4% of boys and 17.8% of girls displayed mental clinical problems. The prevalence of problems did not differ significantly between somatic diagnostic groups. Although the study has low participation, it underlines the necessity of screening all pediatric patients for mental health problems. Future research in pediatric clinics should include factors of psychology because pediatric problems are not caused by somatics alone.     

Parent Programs for Reducing Adolescent’s Antisocial Behavior and Substance Use: A Randomized Controlled Trial

Two theoretically based parent training programs, delivered in real-world settings by the social services, were examined in this randomized controlled trial for effectiveness in reducing adolescents’ antisocial behavior and substance use. Two hundred and thirty-seven (237) adolescents in ages between 12 and 18 and their parents were assigned to one of two programs or to a wait-list control condition. The programs were the nine weekly group sessions program Comet 12–18 (Swedish Parent Management Training Program) and the six weekly ParentSteps (Swedish shortened version by Strengthening Families Program 10–14). Outcome measures were antisocial behavior, substance use, and delinquency, and psychosocial dysfunction. Data based on adolescents’ and parents’ ratings of the adolescents’ problem behavior at baseline and 6 months later were analyzed with repeated measures ANVOA, Logistic regression, and Kruskal–Wallis H test. The results showed that parents’ ratings of adolescents’ antisocial behaviors decreased significantly over time, but no time by group effect emerged. No program effects were found in the adolescents’ self-reported antisocial behavior, delinquency, or psychosocial functioning. A threefold risk of illicit drug use was found in both intervention groups. The results suggest that neither Comet nor ParentSteps had beneficial effects on adolescent’s antisocial or delinquent behavior, or on alcohol use. The only significant group difference found was a threefold risk of drug use in the intervention adolescents at follow-up, but for several reasons this finding should be interpreted with caution.

Longitudinal evidence linking processing speed to the development of reasoning

Age‐related change in processing speed has been linked directly to increases in reasoning as well as indirectly via increases in the capacity of working memory (WM). Most of the evidence linking change in speed to reasoning has come from cross‐sectional research; in this article we present the findings from a 2½‐year longitudinal study of 277 6‐ to‐13‐year‐olds. On three occasions, speed of information processing was assessed with Visual Matching and Cross Out; WM was assessed with reading, listening, backward digit, alphabet, and operation span tasks; and nonverbal reasoning was assessed with Raven's progressive matrices. The results provided consistent evidence of direct links from processing speed to reasoning but inconsistent evidence for indirect links from speed to WM to reasoning. These findings suggest that variations in processing speed may constrain the development of reasoning, directly and perhaps indirectly.
