The current study used meta-analysis to ask whether age differences, sex differences, and family size are linked to differences in parental treatment, as well as whether effect-sizes were moderated by the way parental differential treatment (PDT) was measured, who reported on the PDT, and the domain of PDT. Between August 2015 and November 2020, PsycINFO, Google Scholar, and PubMed Central were searched for articles relating to parental differential treatment; additionally, 13 sibling relationship scholars were contacted to collect unpublished analyses or unused data. Multilevel data came from 13,628 unique participants across 1,388 effect sizes nested within 66 sources (articles/raw data sets), nested within 23 unique samples (74% from North America; 26% from Western Europe). Multilevel meta-analysis conducted in R with the metafor package showed greater differences in parental treatment when siblings were further apart in age or a different sex. The main effects for age spacing, however, were moderated by several factors, particularly the domain of parenting. Specifically, age spacing was linked only to PDT based on control or autonomy granting, meaning when siblings were further apart in age, parents granted more autonomy to one sibling over another. Results were limited, however, by limited sample sizes at the sample level. Overall, findings suggest that parents may, in part, treat siblings differently because they are different to begin with.

本研究采用元分析方法，探讨年龄差异、性别差异和家庭规模是否与父母对待子女的差异有关，以及父母差异对待（PDT）的测量方式、报告 PD 的人员以及 PD 的领域是否会调节效应大小。2015 年 8 月至 2020 年 11 月，在 PsycINFO、Google Scholar 和 PubMed Central 上搜索与父母差异对待相关的文章；此外，还联系了 13 位兄弟姐妹关系学者，收集未发表的分析结果或未使用的数据。多层次数据来自于 13628 名独特参与者的 1388 个效应量，这些效应量嵌套在 66 个来源（文章/原始数据集）中，嵌套在 23 个独特样本中（74%来自北美，26%来自西欧）。在 R 中使用 metafor 包进行的多层次元分析表明，当兄弟姐妹的年龄差异较大或性别不同时，父母的治疗差异更大。然而，年龄间隔的主要效应受到几个因素的调节，特别是育儿的领域。具体来说，年龄间隔仅与基于控制或自主权授予的 PDT 相关，这意味着当兄弟姐妹的年龄差距较大时，父母会给予一个孩子比另一个孩子更多的自主权。然而，由于样本水平的样本规模有限，结果受到限制。总的来说，这些发现表明，父母可能会因为孩子本身的不同而在一定程度上对兄弟姐妹进行不同的对待。（PsycInfo 数据库记录（c）2023 APA，保留所有权利）。
