Background Worldwide, approximately one in eight children or adolescents suffer from a mental disorder. The present study was designed to determine the cross-national prevalence of mental health problems in children aged 6–11 across seven European countries including Italy, Germany, the Netherlands, Lithuania, Bulgaria, Romania, and Turkey. Methods Data were collected on 7682 children for whom either parent- or teacher SDQ were completed. Results The present study provides country-specific normative banding for both parent- and teacher SDQ scores. Overall, 12.8 % of children have any probable disorder, with rates ranging from 15.5 % in Lithuania to 7.8 % in Italy, 3.8 % of children have a probable emotional disorder, 8.4 % probable conduct disorder, and 2.0 % probable hyperactivity/inattention. However, when adjusting for key sociodemographic variables and parental psychological distress, country of residence did not predict the odds of having any disorder. For specific disorders, however, country of residence does have an effect on the odds of presenting with mental health problems. Conclusions As normative data are key in the comparison of mental health status on an international level, the present data considerably advance the possibilities of future research. Furthermore, the findings underline the importance of controlling for a number of sociodemographic and parental variables when conducting international comparisons of child mental health. In addition, the findings suggest that efforts are needed locally to assist in the detection and prevention of parental psychological distress.

Background Video games are one of the favourite leisure activities of children; the influence on child health is usually perceived to be negative. The present study assessed the association between the amount of time spent playing video games and children mental health as well as cognitive and social skills. Methods Data were drawn from the School Children Mental Health Europe project conducted in six European Union countries (youth ages 6–11, n = 3195). Child mental health was assessed by parents and teachers using the Strengths and Difficulties Questionnaire and by children themselves with the Dominic Interactive. Child video game usage was reported by the parents. Teachers evaluated academic functioning. Multivariable logistic regressions were used. Results 20 % of the children played video games more than 5 h per week. Factors associated with time spent playing video games included being a boy, being older, and belonging to a medium size family. Having a less educated, single, inactive, or psychologically distressed mother decreased time spent playing video games. Children living in Western European countries were significantly less likely to have high video game usage (9.66 vs 20.49 %) though this was not homogenous. Once adjusted for child age and gender, number of children, mothers age, marital status, education, employment status, psychological distress, and region, high usage was associated with 1.75 times the odds of high intellectual functioning (95 % CI 1.31–2.33), and 1.88 times the odds of high overall school competence (95 % CI 1.44–2.47). Once controlled for high usage predictors, there were no significant associations with any child self-reported or mother- or teacher-reported mental health problems. High usage was associated with decreases in peer relationship problems [OR 0.41 (0.2–0.86) and in prosocial deficits (0.23 (0.07, 0.81)]. Conclusions Playing video games may have positive effects on young children. Understanding the mechanisms through which video game use may stimulate children should be further investigated.

Assessments of child psychopathology are often derived from parental and teacher reports, yet there is substantial disagreement. This study utilized data from 7 European countries to examine parent-teacher agreement and possible explanatory factors for parent-teacher disagreement such as child and family characteristics, parenting dimensions, and maternal distress were explored. Parent-teacher agreement of the Strengths and Difficulties Questionnaire were assessed using a cross-sectional survey of 4,894 school aged children 6-11 from the School Children Mental Health Europe Project. Parent-teacher agreement was low to moderate (Pearson correlation ranging from .24 (Prosocial) to .48 (Hyperactivity) for the 5 subscales across 7 countries); kappa coefficient ranged from .01 (Turkey) to .44 (Italy) for internalizing problems and .19(Romania) to .44(Italy) for externalizing problems. Child's gender and age, mother's employment status, single parent home, number of children in household, and selected parenting dimension were found to be explanatory of informant disagreement. This study not only serves to advance our understanding of parent-teacher agreement of the Strengths and Difficulties Questionnaire in 7 European countries but provides a novel approach to examining the factors that contribute to informant disagreement.
