This could lead to behavior- and emotion regulation problems including anxiety. During a stressful life event it is crucial to be able to control/use cognitive emotion regulation strategies (Thompson, 1994). If this fails, it can lead to behavior- or social development problems. Although separate results from previous studies suggest a link between anxiety, regulation problems and stressful life events, this possible coherence has not been studied yet for Klinefelter children. Method: To investigate this, 95 children in the age of 1-7 years (of which 51 children with Klinefelter) and their parents participated in a series of questionnaires (Child Behavior Checklist, Children’s Behavior-/Early Childhood Behavior-/VMG Life Events Questionnaire). Results: Children with Klinefelter were found to be more anxious and showed a less expressive internal regulation state compared to the control group, according to their parents. According to the CBQ/ECBQ Reactivity/Soothability subscale results, children with Klinefelter showed less expressive (blunted) emotions when they were in pain, upset or experienced an exciting activity/event. In addition, stressful life events turned out to be a predictor for anxious depressed behavior in children with Klinefelter. There was also no interaction found for the degree of stressful life events and anxious/depressed or reactivity/soothability behavior within the Klinefelter- or control group. Conclusion: Children with Klinefelter experience more anxiety/depressed behavior and less expressive internal regulation state than children without Klinefelter. An association between stressful life events and anxiety/depressed behavior is found within children with Klinefelter, but there is no evidence found for a coherence between stressful life events and regulation problems. Furthermore, no interaction was found between the degree of stressful life events and anxious/depressed or reactivity/soothability behavior within the Klinefelter- or control group.Show less

This study investigates through group comparisons to what extent the timing of diagnosis (prenatal/postnatal) influences the type and degree of problem behavior of children aged 1-7 years. In total, 93 children (71 prenatal and 22 postnatal) with an extra X or Y chromosome and 102 non-clinical controls and their parents participated in the study. Types of problem behavior were assessed using the Child Behavior Checklist (CBCL) and a medical history questionnaire. The results indicate that children with SCT generally show more total and internalizing problem behavior than typically developing children, but not significantly more externalizing problem behavior. When it comes to specific problem behaviors, SCT children generally have a shorter attention span, are more easily distracted, tend to be more withdrawn and isolated, worry and experience anxieties and are more sensitive to stimuli and moodiness. The results show that no differences are found in total, internalizing and externalizing problem behavior between children with a prenatal and postnatal diagnosis. However, children with a postnatal diagnosis generally worry more excessively, experience anxiety and are often more irritable compared to children with a prenatal diagnosis of SCT. Finally, the results show that temper tantrums/oppositional behavior, short span of attention/distractibility and excessive worry and fear within the clinical group increases with age. In conclusion, this suggests that it is important to bring the possible consequences of SCT to the attention of medical care providers and parents, so that these children do not worry excessively, experience anxiety and are more irritable (anymore). This proves that there is a need for early interventions in children with SCT, to ensure the quality of life and to reduce the risk of mental health problems.Show less
