Children of divorce in a Scandinavian welfare state: Are they less affected than US children?

A fairly common view holds that children's risks of negative outcomes associated with family dissolution are generally small or even nonexistent in Scandinavia, and clearly smaller than what is usually found in the United States. This view was empirically examined in a recent large-scale study of 4,127 12–15-year-old children in Norway, of whom 623 had experienced parental divorce and lived in a single-mother family. The somewhat paradoxical pattern of findings was as follows: (a) The negative associations between parental divorce and various outcomes were found to be generally very similar in Norway and the United States in spite of the great differences in family policy and welfare benefits for single mothers (at the macro level); and (b) Mediational effects of family economic resources were in both countries most marked for the academic achievement area, and the predictive power of such variables was quite similar, again in spite of the great differences in absolute level of the economic resources available to single-mother families in the two countries. The results cast some doubt on the value of the absolute economic deprivation perspective in explaining the results, and the many Norwegian welfare benefits do not seem to mitigate the association between divorce and negative outcomes for the children involved. Also policy implications derived from the economic deprivation perspective are questioned. Alternative interpretations of the findings involving relative deprivation and economic resources as a partial proxy for other non-economic factors are briefly discussed.     

Children’s eyewitness memory: A comparison of two interviewing strategies as realized by forensic professionals

A critical issue for developmental psychology is how to obtain accurate and complete eyewitness memory reports from preschoolers without offering suggestions that might result in false allegations. We examined effects of two interviewing strategies (police/verbal interviews and clinician/prop-assisted interviews) on young children’s reports about a medical examination. A total of 58 4-year-olds participated in the study, which conformed to a 2 (Interview Type) × 2 (Number of Interviews) factorial design. Analyses revealed that interviewers spent less time off topic and asked more free recall questions in the police/verbal interviews than in the clinician/prop-assisted interviews. Compared with police/verbal interviews, clinician/prop-assisted interviews resulted in significantly more correct rejections and commission errors in children’s memory reports. However, on a final free recall test, error rates were comparable across conditions. Higher child verbal intelligence predicted memory accuracy in police/verbal interviews, and greater parental attachment anxiety predicted children being asked a higher number of misleading questions. The study provides new insights into interview techniques that promote preschoolers’ accurate eyewitness reports.     

Psychometric properties of the Norwegian version of the Childhood Trauma Questionnaire in high‐risk groups

The Childhood Trauma Questionnaire ‐ Short Form (CTQ‐SF) is widely used to measure childhood abuse of all types. In the present study, we examined the psychometric properties of the Norwegian version of the instrument. The participants constituted four subsamples (n = 517): substance abusers (n = 126), psychiatric patients (n = 210), prisoners (n = 109) and adolescents in out‐of‐home placements (n = 72). Confirmatory factor analysis revealed a reasonable fit of the data to the original five‐factor structure of the CTQ‐SF. Measurement invariance was found across gender and the four subsamples. It was concluded that the Norwegian version of the CTQ‐SF has acceptable psychometric properties, with good reliability and satisfactory accuracy, to assess different dimensions of childhood trauma.     

Nanoscale inclusions in the phonon glass thermoelectric material Zn4Sb3

We have investigated the thermoelectric material Zn₄Sb₃ using transmission electron microscopy (TEM). Nanoscale inclusions with a diameter of about 10 nm were observed, constituting on the order of 1% by volume of the material. Studies using energy filtered imaging, electron diffraction, and high-angle annular dark-field STEM indicate that the inclusions consist of Zn. These inclusions are expected to scatter the medium and long-wavelength phonons effectively, thus contributing to phonon glass behavior which results in the exceptionally low thermal conductivity for this thermoelectric material.     

Reconsidering formative measurement

The relationship between observable responses and the latent constructs they are purported to measure has received considerable attention recently, with particular focus on what has become known as formative measurement. This alternative to reflective measurement in the area of theory-testing research is examined in the context of the potential for interpretational confounding and a construct's ability to function as a point variable within a larger model. Although these issues have been addressed in the traditional reflective measurement context, the authors suggest that they are particularly relevant in evaluating formative measurement models. On the basis of this analysis, the authors conclude that formative measurement is not an equally attractive alternative to reflective measurement and that whenever possible, in developing new measures or choosing among alternative existing measures, researchers should opt for reflective measurement. In addition, the authors provide guidelines for researchers dealing with existing formative measures.     

Forensic interviews with children in CSA cases: A large‐sample study of Norwegian police interviews

The study was designed to investigate changes in how children are interviewed in cases of child sexual abuse over a fairly long period of time. The interviewers' utterances were analysed in a large sample of forensic interviews conducted in Norway during the period of 1990–2002. The results indicate that interviewer strategies have improved during this period; there is a decrease in the proportion of suggestive, yes/no and option‐posing utterances, accompanied by a comparable increase in directive utterances. However, the frequency of open‐ended utterances is low, and has not changed much over time. An index of the overall quality of the interviews likewise showed a positive trend, with an increase in the proportion of interviews that were labelled ‘good’. However, even in recent years, interviews rated as ‘inadequate’ or ‘poor’ constituted half of the interviews conducted. Copyright © 2008 John Wiley & Sons, Ltd.     

Best Practice Recommendations Still Fail to Result in Action: A National 10‐Year Follow‐up Study of Investigative Interviews in CSA Cases

The present study examined a national sample of Norwegian investigative interviews in alleged child sexual abuse cases (N = 224) across a 10‐year period (2002–2012), in order to decide whether practice had improved over the decade in terms of the types of questions asked. The results indicate that the frequency of open‐ended, directive, option‐posing, and suggestive questions asked was unchanged during the 10‐year period, but that the frequency of repeated questions had increased significantly. When analyzed together with the results from a previous study of interview practice covering the period of 1990–2002, long‐term trends were found to be similarly stable, with no change in the frequency of open‐ended and suggestive questions asked over a 22‐year perspective. However, a decreasing frequency of option‐posing questions observed accompanied by an increasing frequency of directive questions may be considered a positive trend.
