De Relatie Tussen Emotieregulatie en Externaliserend  Probleemgedrag bij Jongens met een Extra Y-Chromosoom

Around 1:1000 boys is born with the XYY-syndrome, meaning they are born with an extra Ychromosome. Developmental and behavioral outcomes of some of these boys include increased levels of externalizing behavioral problems and difficulties with emotion regulation, while other boys show no developmental or behavioral problems at all. This study investigates whether boys with the XYYsyndrome have an increased risk of developing externalizing behavioral problems and problems with emotion regulation, whether these outcomes are related to each other, and whether this relationship differs for XYY-boys as compared to normally developing (XY-)boys. This study is of a case control, observational design and is carried out in The Netherlands, Belgium, and the United States. It includes 24 XYY-boys and 44 XY-boys, ranging in age from 1 to 8 years old. Data is collected using questionnaires. Statistical analysis is carried out via independent samples t-tests and multiple regression analyses.

This study investigates whether boys with the XYYsyndrome have an increased risk of developing externalizing behavioral problems and problems with emotion regulation, whether these outcomes are related to each other, and whether this relationship differs for XYY-boys as compared to normally developing (XY-)boys. This study is of a case control, observational design and is carried out in The Netherlands, Belgium, and the United States. It includes 24 XYY-boys and 44 XY-boys, ranging in age from 1 to 8 years old. Data is collected using questionnaires. Statistical analysis is carried out via independent samples t-tests and multiple regression analyses. The results indicate that although XYY- and XY-boys do not differ regarding their levels of externalizing behavioral problems, XYY-boys do appear to have more – albeit still nonclinical – problems with emotion regulation than XY-boys. Moreover, there exists a positive relationship between problematic emotion regulation and externalizing behavior problems, but this relationship is not different for XYY-boys as compared to XY-boys. Since emotion regulation affects many aspects of human’s daily lives, and since XYY-boys are at higher risk for developing emotion regulation problems, this research suggests to monitor XYY-boys’ emotion regulation development from an early age onwards. This should help to detect problems early and prevent or minimize further developmental risks of XYY-boys. Further research including larger samples should be carried out to more thoroughly examine the risk at emotion regulation problems, externalizing behavioral problems and the relationship between the two in boys with an extra Y-chromosome.Show less
