Few studies have examined the prevalence and treatment of narcissistic personality disorder (NPD).
We systematically reviewed studies of NPD that used suitable diagnostic methods in adult nonclinical samples and evaluated their strengths and weaknesses. Searches were conducted of MEDLINE (using both MeSH category and free-word search terms), PsycINFO, and PsycLIT for articles in English from January 1980 to August 2008 using the terms Narcissis* and prevalence, of unpublished work identified via contacts with experts in the field, of books on personality disorders, and of reference lists from relevant articles and books. We evaluated articles using a 6-point epidemiologic quality tool that we developed. To determine the most efficacious treatments for NPD without other comorbidities, we performed searches using Narcissis*, pharmacology, clinical pharmacology, therapeutics, and psychotherapy for reports of controlled trials from January 1980 to August 2008.
We identified 7 prevalence studies that had used a structured or semistructured interview, 5 of which scored 5/6 using the epidemiologic quality tool. Mean prevalence was 1.06%, and the range was 0% to 6.2%. We found no studies of treatment meeting our inclusion criteria.
There was an overall finding of a low prevalence of NPD in adult nonclinical samples. Changes in the classification system might promote further empirical investigations.
很少有研究调查过自恋型人格障碍（NPD）的流行率和治疗情况。
我们系统地回顾了使用适当诊断方法在非临床成年人群中评估 NPD 的研究，并评估了它们的优缺点。我们使用 MEDLINE（使用 MeSH 类别和自由词搜索词）、PsycINFO 和 PsycLIT，从 1980 年 1 月到 2008 年 8 月，以“Narcissis*”和“流行率”为关键词，搜索英文文献；通过与该领域专家联系，查找未发表的工作；查阅人格障碍方面的书籍和相关文章和书籍的参考文献列表。我们使用我们开发的 6 点流行病学质量工具评估文章。为了确定无其他合并症的 NPD 的最有效治疗方法，我们使用“Narcissis*”、药理学、临床药理学、治疗学和心理疗法，从 1980 年 1 月到 2008 年 8 月，搜索对照试验报告。
我们确定了 7 项使用结构或半结构访谈的流行率研究，其中 5 项使用流行病学质量工具得分为 5/6。平均流行率为 1.06%，范围为 0%至 6.2%。我们没有找到符合我们纳入标准的治疗研究。
总体上发现非临床成年人群中 NPD 的流行率较低。分类系统的变化可能会促进进一步的实证研究。
