The presence of an additional X or Y chromosome (sex chromosome trisomies, SCT) is associated with an increased risk for neurodevelopmental difficulties, including socio-emotional problems, across the life span. Studying emotion regulation in young children with SCT could signal deviations in emotional development that serve as risk markers to guide clinical care. This study explored the presence and variety of emotion regulation strategies in 75 SCT children and 81 population-based controls, aged 1–7 years, during a frustration-inducing event in which physiological (heart rate) and observational data (behavioral responses) were collected. Children with SCT were equally physiologically aroused by the event as compared to controls. However, they showed more emotion regulation difficulties in terms of behavior compared to controls that were not explicable in terms of differences in general intellectual functioning. Specifically, they had a more limited range of behavioral...Show moreThe presence of an additional X or Y chromosome (sex chromosome trisomies, SCT) is associated with an increased risk for neurodevelopmental difficulties, including socio-emotional problems, across the life span.

This study explored the presence and variety of emotion regulation strategies in 75 SCT children and 81 population-based controls, aged 1–7 years, during a frustration-inducing event in which physiological (heart rate) and observational data (behavioral responses) were collected. Children with SCT were equally physiologically aroused by the event as compared to controls. However, they showed more emotion regulation difficulties in terms of behavior compared to controls that were not explicable in terms of differences in general intellectual functioning. Specifically, they had a more limited range of behavioral alternatives and tended to rely longer on inefficient strategies with increasing age. The field of practice should be made aware of these early risk findings regarding emotion regulation in SCT, which may potentially lay the foundation for later socio-emotional problems, given the significant impact of emotion regulation on child and adult mental health outcomes. The current results may help to design tailored interventions to reduce the impact of the additional sex chromosome on adaptive functioning, psychopathology, and quality of life.
