Abstract: | Of 1,409 eligible children aged 6-13 years in grades 1 to 7 who were randomly selected from a national sample of Norwegian schools, 858 participated in the present study (60.9%). The sample was stratified by school centrality, region and size of grade cohort. The teachers assessed their children's academic performance, adaptive school functioning, and levels of emotional/behavioral problems using the 2001 version of the Teacher Report Form (TRF). Only one child was randomly selected from each grade cohort. Girls had significantly higher scores than boys in the Working Hard, Appropriate Behavior, Learning, and Total Adaptive Functioning domains. For girls, only the Working Hard domain was of medium effect size. While boys had significantly higher scores than girls on Attention, Thought Problems, Rule-Breaking, Aggression, Externalizing Problems and Total problems, only Attention Problems showed a medium effect size. Significant sex by age interaction effects were also found for Rule-Breaking, Externalizing, Internalizing, Anxious-Depressed and Total Problems. In all these comparisons, 10-13-year-old boys had significantly higher scores than 6-9-year olds, while girls had similar problem levels across age groups. Our mean Total Problems score (17.2) was lower than the grand mean (21.6) reported in a multi-country comparison but higher than in another Norwegian large-scale survey. Overall, our findings indicate that teachers in Scandinavia report, just as do parents, relatively low levels of emotional/behavioral problems among school-aged children. |
