Insights
Sibling compliance differences in preschoolers are influenced by birth order and parenting styles. Second-borns show more compliance, especially when firstborns receive more physical discipline, highlighting the role of differential parenting.
Area of Science:
- Developmental Psychology
- Family Studies
- Child Behavior
Background:
- Sibling dynamics significantly shape child development, yet the interplay of birth order and parenting in fostering compliance requires deeper investigation.
- Understanding within-family variations in child compliance is crucial for developmental and educational contexts.
Purpose of the Study:
- To examine how birth order and differential parenting influence sibling differences in preschool compliance.
- To disaggregate situational, within-family, and between-family effects on compliance development.
Main Methods:
- Employed a within-family, age-snapshot design with observational data from 311 Dutch families.
- Utilized three-level cross-classified multilevel models to analyze data from 3- and 4-year-old siblings and their parents.
Main Results:
- Observed sibling noncompliance and differential verbal discipline directly impacted child noncompliance.
- Second-born children exhibited greater compliance than firstborns, particularly when firstborns experienced more physical discipline.
Conclusions:
- Birth-order effects on compliance are partially mediated by differential parenting practices.
- Sibling differences in compliance are a complex interplay of direct and indirect sibling influences and parenting variations.
Abstract:
This study applies a within-family, age-snapshot design to investigate differences between siblings in the development of compliance during the preschool years by disaggregating situational, within-family, and between-family effects. The aim of the study was to investigate the relation between sibling differences in compliance and the within-family factors birth order and differential parenting, as well as interactions between these factors. Using observational data of 311 Dutch families (self-identified as culturally Dutch) with 2 children when each child was 3 and 4 years old (firstborns: 36.2 months old; SD = 3.6; 48% girls, second-borns (2 years later): 36.67 months old; SD = .62; 47% girls) and both parents. Three-level cross-classified multilevel models showed main effects of observed sibling noncompliance and differential verbal discipline on noncompliance. In addition, second-born children were more compliant than their firstborn siblings, but only when the firstborn was disciplined physically more often than his/her younger sibling. The results provide evidence that birth-order effects may partially be explained by differential parenting and suggest that differences between siblings cannot be fully understood without taking into account the influence of both direct and indirect sibling effects.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
