Testing links between childhood positive peer relations and externalizing outcomes through a randomized controlled intervention study

In this study, the authors used a randomized controlled trial to explore the link between having positive peer relations and externalizing outcomes in 758 children followed from kindergarten to the end of 2nd grade. Children were randomly assigned to the Good Behavior Game (GBG), a universal classroombased preventive intervention, or a control condition. Children’s acceptance by peers, their number of mutual friends, and their proximity to others were assessed annually through peer ratings. Externalizing behavior was annually rated by teachers. Reductions in children’s externalizing behavior and improvements in positive peer relations were found among GBG children, as compared with control-group children. Reductions in externalizing behavior appeared to be partly mediated by the improvements in peer acceptance. This mediating role of peer acceptance was found for boys only. The results suggest that positive peer relations are not just markers, but they are environmental mediators of boys’ externalizing behavior development. Implications for research and prevention are discussed

Conservation science and discursive violence: a response to two rejoinders

We respond to two rejoinders to our review article “Science for Success,” which proposed fuller contextualization of epistemological approach, researcher position and interests in conservation research. This way readers—including reviewers and journal editors—can better understand and interpret findings. We suggest this contextualization is particularly important when conservation and development professionals undertake research about programs they are involved in, as this can potentially create a conflict of interest. Both rejoinders follow an extended process of complaint about our article that included academic and legal threats, and ad hominem attacks, with little engagement with the points made about researcher positionality. We consider this to be a form of “discursive violence” deployed to silence unfavorable perspectives, confirming our argument that positionality in conservation (research) begs self-reflection and transparent disclosure

Exploring views on satisfaction with life in young children with chronic illness: an innovative approach to the collection of self-report data from children under 11

The objective of this study was to explore young children’s views on the impact of chronic illness on their life in order to inform future development of a patient-based self-report health outcome measure. We describe an approach to facilitating self-report views from young children with chronic illness. A board game was designed in order to obtain qualitative data from 39 children with a range of chronic illness conditions and 38 healthy controls ranging in age from 3 to 11 years. The format was effective in engaging young children in a self-report process of determining satisfaction with life and identified nine domains. The board game enabled children aged 5–11 years with chronic illness to describe the effects of living with illness on home, family, friends, school and life in general. It generated direct, non-interpreted material from children who, because of their age, may have been considered unable or limited their ability to discuss and describe how they feel. Obtaining this information for children aged 4 and under continues to be a challenge

Hormone replacement therapy, mammography screening and changing age-specific incidence rates of breast cancer: an ecological study comparing two European populations

Background: In 2003, for the first time, US breast cancer incidence rates have fallen. Experts argue whether this is due to the reduced uptake of screening mammography or to lower use of Hormone Replacement Therapy (HRT). This study aims to disentangle the respective impact of screening and HRT on age-incidence rates and histology of breast cancer, by comparing two populations with comparably high levels of screening mammography, but with different prevalence of HRT. Methods: We included all invasive breast cancers recorded at the Geneva cancer registry (n=4,909) and the Netherlands Cancer Registry (n=152,428) between 1989-2003. We compared age-specific incidence rates and trends in histological subtyping between the two populations. Results: Between 1989-1991, incidence rates increased with age in both populations. In 2001-2003, women aged 60-64years showed highest incidence rates in Geneva, while in the Netherlands incidence rates continued to increase with age. The annual increase in ductal cancer incidence was similar in the Netherlands (2.3%) and Geneva (2.5%), but the annual increase in lobular cancer was sharper in Geneva (10%) than in the Netherlands (5%). Conclusion: The sharp differences in age distribution and histological subtyping of breast cancer between two European populations are not attributable to screening, since both populations have a high uptake of mammography screening. Since the prevalence of HRT use is very high in Geneva and rather low in the Netherlands, HRT may explain these discrepancies. However, other etiological factors and differences in histological assessment may also have played a rol

Do children with autism acknowledge the influence of mood on behaviour?

We tested whether children with and without high-functioning autism spectrum disorders (HFASD) differ in their understanding of the influence of mood states on behaviour. A total of 122 children with HFASD or typical development were asked to predict and explain the behaviour of story characters during hypothetical social interactions. HFASD and typically developing children predicted at equal rates that mood states likely result in similar valenced behaviour. 'Explicit' descriptions were used to explain predictions more often by children with HFASD than by typically developing children. However, 'implicit' and 'irrelevant' descriptions elicited fewer mood references among HFASD children. Furthermore, they less often referred to the uncertainty of the influence of mood on behaviour, and less often used mood-related explanations, in particular when they had to rely on implicit information. This may indicate a rote- rather than self-generated understanding of emotions in children with HFASD. © SAGE Publications, Inc. 2007
