Temperament in children with Down syndrome and in prematurely born children

Area of Science:

• Developmental Psychology
• Child Psychology
• Behavioral Science

Background:

• Temperament is a crucial aspect of child development, influencing social and emotional functioning.
• Understanding temperament differences in children with Down syndrome and those born prematurely is vital for targeted support.
• The Children's Behavior Questionnaire (CBQ) is a standardized tool for assessing childhood temperament.

Purpose of the Study:

• To compare temperament levels and structures between children with Down syndrome, prematurely born children, and typically developing children.
• To identify specific behavioral differences in attentional focusing, inhibitory control, and emotionality across the groups.
• To examine the cross-cultural generalizability of temperament structures.

Main Methods:

• Parents completed the Children's Behavior Questionnaire (CBQ) for their children.
• Participants included children with Down syndrome (n=55, aged 4-11), prematurely born children (n=97, aged 5), and typically developing children (n=91, aged 5-7).
• Statistical analyses compared mean temperament scores and factor structures across the three groups.

Main Results:

• Children with Down syndrome demonstrated significantly less attentional focusing, inhibitory control, and sadness compared to typically developing children.
• A clearer emotional factor of "surgency" was observed in children with Down syndrome.
• Prematurely born children showed less attentional focusing than the control group.
• Temperament structures were consistent with previous studies in China and the US.

Conclusions:

• Children with Down syndrome exhibit distinct temperament profiles, particularly in self-regulation and emotional expression.
• Early attention difficulties may be a characteristic of prematurely born children.
• Temperament structures appear to be relatively consistent across different cultural contexts and developmental conditions.
