A series of recent epidemiological studies has assessed the prevalence of personality disorders in the general population. However, all these reports run a serious risk of overestimation. First, all research is based on problematic definitions in DSM-IV-TR, both for overall PD and for specific categories. Second, all studies suffer from a failure to distinguish problematic traits from clinical disorders. Third, many methods of assessment have been inadequate to make diagnostic decisions requiring subtlety and clinical experience. Overestimation of prevalence negatively affects research, which would benefit from a narrower definition of PDs based on dysfunction in multiple domains.
最近的一系列流行病学研究评估了一般人群中心理人格障碍的流行率。然而，所有这些报告都存在严重的高估风险。首先，所有研究都基于 DSM-IV-TR 中的有问题的定义，无论是整体 PD 还是特定类别。其次，所有研究都未能区分有问题的特征和临床障碍。第三，许多评估方法都不充分，无法做出需要微妙和临床经验的诊断决策。患病率的高估对研究产生负面影响，而基于多个领域功能障碍的更狭义的 PD 定义将使研究受益。
