[Family stressors on young children's emotional development]

Adverse childhood experiences (ACE) have been pointed out as risk factors for physical and mental health, with consequences extending from childhood into adulthood. Based on research regarding the effects of selected ACE as well as the accumulation of ACE, this article investigates how different types of family stressors are linked to children's negative emotionality in infancy and early childhood.

Data are from the KiD 0-3 study (N = 5583) and the follow-up of a subsample after 2 years (n = 681). Based on 14 stress factors, we distinguish families with no/little stressors, socioeconomic stressors, parenting stressors, and multiple stressors.

Children in multiply stressed families have the highest risk of high negative emotionality (compared to unstressed families: Odds Ratios [OR] ranging from 13.00 to 6.81), controlling for demographic characteristics, child-related stress factors (e.g., excessive crying), and caregiver childhood stress. Children in families primarily characterized by parenting stress also showed a significantly increased risk of high negative emotionality (OR ranging from 8.31 to 6.95), whereas this did not hold for children from socioeconomically stressed families (without parenting stress) compared to those from unstressed families. Longitudinal analyses of the follow-up subsample showed that changes in the number of stressors were also associated with parallel changes in children's negative emotionality.

These results confirm findings from international research on ACE in Germany and for early childhood. They underline the importance of a well-developed early intervention system.
