Why More Siblings Harm Teen Mental Health?

Listen to this News

Highlights:

• Teenagers from larger families with more siblings often encounter poor mental health compared to those with fewer siblings
• Factors such as parental resource dilution and socioeconomic conditions can contribute to adverse mental health outcomes in teenagers
• Enhancing social skills among siblings and reducing the probability of divorce in adults with multiple siblings can positively contribute to their mental health

The impact of sibling dynamics on various aspects of individuals' lives has been a subject of extensive research, with contrasting findings that highlight both positive and negative outcomes. One intriguing aspect of this exploration is the influence of family size on mental health, particularly among teenagers.

A comprehensive analysis of children in the United States and China reveals that teenagers from larger families tend to experience poorer mental health compared to those with fewer siblings. The specific patterns vary based on factors such as the age spacing between siblings and their ages.

Surprisingly, this overall pattern was observed in both countries, emphasizing its significance, according to Doug Downey, the study's lead author and a sociology professor at The Ohio State University.

The Chinese analysis involved over 9,400 eighth graders from the China Education Panel Study, while the U.S. data included more than 9,100 American eighth graders from the Early Childhood Longitudinal Study - Kindergarten Cohort of 1988.

In China, teens without siblings displayed the best mental health, while in the United States, those with no or one sibling exhibited similar mental health. The U.S. data showed that both half and full siblings are associated with poorer mental health, with older and closely spaced siblings having the most detrimental impact.

Downey suggests that the findings align with the "resource dilution" explanation- sharing of parental resources. In single-child families, the child receives all the attention and resources, whereas in larger families, each child receives fewer resources, potentially impacting their mental health.
