Abstract：
Emerging evidence has documented the positive association between child maltreatment and both phenotypes of pathological narcissism (i.e., vulnerable and grandiose narcissism). However, results across these studies are inconsistent. Therefore, the present meta-analysis aimed to examine the extent to which child maltreatment is associated with vulnerable and grandiose narcissism, and whether these associations differed by study or sample characteristics. A systematic literature review was conducted in Web of Science, ScienceDirect, PubMed, Google Scholar, and China National Knowledge Infrastructure. Three-level meta-analyses were performed in R to synthesize the effect sizes. A total of 15 studies (N = 9,141 participants) producing 129 effect sizes were included. Results showed that child maltreatment was positively related to both vulnerable narcissism (mean r = .198; p < .001) and grandiose narcissism (mean r = .087; p < .001), but only to a small extent. Further, the association between child maltreatment and vulnerable narcissism was stronger for neglect (r = .278) than for physical abuse (r = .130). The strength of the association between child maltreatment and grandiose narcissism was larger for samples that were on average younger than 18 years (r = .187) than for samples that were on average older than 18 years (r = .068). Also, the strength of the association was stronger for females than for males. Child maltreatment is a risk factor for developing both vulnerable and grandiose narcissism. Interventions targeting pathological narcissism should be aware of potential trauma resulting from victimization of child maltreatment.
摘要：
新出现的证据表明，儿童虐待与病理性自恋的两种表型之间存在正相关关系(即，脆弱和宏伟的自恋)。然而,这些研究的结果不一致。因此,本荟萃分析旨在检查虐待儿童与脆弱和傲慢的自恋相关的程度，以及这些关联是否因研究或样本特征而异。在WebofScience上进行了系统的文献综述，ScienceDirect,PubMed,谷歌学者，和中国国家知识基础设施。在R中进行三级荟萃分析以合成效应大小。总共包括15项研究（N=9,141名参与者），产生129个效应大小。结果表明，儿童虐待与脆弱的自恋（平均r=.198;p<.001）和夸张的自恋（平均r=.087;p<.001）呈正相关，但只是在很小的程度上。Further,儿童虐待和脆弱自恋之间的关联在忽视(r=0.278)比身体虐待(r=0.130)更强。平均年龄小于18岁的样本（r=.187）比平均年龄大于18岁的样本（r=.068），儿童虐待与自恋之间的关联强度更大。此外，女性的关联强度比男性强。虐待儿童是发展脆弱和傲慢自恋的危险因素。针对病理性自恋的干预措施应意识到因虐待儿童而造成的潜在创伤。
