Cross-Cultural Differences in Sibling Power Balance and Its Concomitants Across Three Age Periods.

Area of Science:

• Developmental Psychology
• Cross-Cultural Psychology
• Child Psychology

Background:

• Sibling relationships significantly influence child development.
• Understanding cross-cultural variations in sibling dynamics is crucial for a comprehensive view of child psychology.
• Previous research has not extensively explored cultural differences in sibling power dynamics and their behavioral correlates.

Purpose of the Study:

• To investigate cross-cultural differences in sibling power balance.
• To examine the association between sibling power balance and internalizing/externalizing problems across different age groups and cultures.
• To compare these dynamics in Turkish, Dutch, Indian, and Moroccan samples.

Main Methods:

• Three cross-cultural studies were conducted, involving early childhood, late childhood, and adolescent samples.
• Data collection utilized questionnaires administered to mothers (early childhood) and self-reports from children and adolescents.
• Participants included Turkish, Dutch, Indian, and ethnic Moroccan children and adolescents.

Main Results:

• Only one significant cross-cultural difference emerged: Indian children reported higher sibling power imbalance than Dutch children.
• Associations between sibling power imbalance and problem behaviors were largely consistent across cultural groups.
• A stronger link between sibling power imbalance and externalizing problems was observed in the Dutch sample compared to the Turkish sample.

Conclusions:

• Sibling power imbalance exhibits minimal cross-cultural variation.
• Across cultures and developmental stages, greater sibling power imbalance is associated with increased internalizing and externalizing problems.
• The findings underscore the universal impact of sibling power dynamics on child behavioral outcomes.
