The Relative Researches of Only Children and Children with Siblings in Taiwan: A Meta-analysis
Abstract
This meta-analysis included 20 studies involving about 14,090 individuals and 30 outcomes. The question
addressed was whether “only child or non-only child” is associated with relative factors of the past quantitative literature in
Taiwan and what the strength of these relations are. The researchers analyzed the possible moderators and proposed a
possible model. The main results were found: (i)In the aspect of self-concept, "only children or children with siblings " were
significant on family self-concept and school self-concept, children with siblings were better than only children, and
according to Cohen’s(1977) conventional criteria, the effect size was medium; however, there was no significant relationship
between "only children or children with siblings " and the appearance self-concept, body self-concept, and emotional selfconcept;(
ii)In school life adaptation, "only child or children with siblings " were significant on learning adaptation , routine
adaptation, peers relationship and teacher-student relationship , children with siblings were better than only children, but the
effect size is small; ; (iii)In the aspect of attachment, there was no significant relationship between "only children or children
with siblings " and their attachment with fathers or attachment with mothers.(iv)In the aspect of social behavior, there was no
significant relationship between "only children or children with siblings " and their prosocial behavior.
