In this study, the authors evaluated aspects of criterion validity and clinical utility of the grandiosity and vulnerability components of the Pathological Narcissism Inventory (PNI) using two undergraduate samples (N = 299 and 500). Criterion validity was assessed by evaluating the correlations of narcissistic grandiosity and narcissistic vulnerability with established indices of normal personality traits, psychopathology and clinical concerns, and pathological personality traits. Overall, the pattern of correlations supported the convergent and discriminant validity of grandiose and vulnerable conceptualizations of pathological narcissism as measured by the PNI. Clinical utility was assessed by evaluating the extent to which clinicians without specific training in pathological narcissism as well as clinicians with expertise in pathological narcissism could accurately predict the correlates of PNI grandiosity and vulnerability with normal and pathological personality traits and psychopathology. The r(contrast-cv) coefficient provided a global index of accuracy in clinicians' predictions that was more fully elaborated by examining systematic discrepancies across groups. Overall, novice and expert clinicians were generally able to predict criterion correlations, with some exceptions (e.g., counter to predictions, pathological narcissism was negatively associated with treatment resistance). These results provide further evidence regarding the validity and utility of the narcissistic grandiosity and narcissistic vulnerability constructs as measured by the PNI.
在这项研究中，作者使用两个本科生样本（N=299 和 500）评估了病理性自恋量表（PNI）的浮夸和脆弱性分量表的准则有效性和临床实用性。准则有效性通过评估自恋浮夸和自恋脆弱性与既定的正常人格特质、精神病理学和临床关注以及病理性人格特质的指标之间的相关性来评估。总体而言，相关性模式支持了 PNI 测量的病理性自恋浮夸和脆弱性概念的收敛和区分效度。临床实用性通过评估没有病理性自恋特定培训的临床医生以及具有病理性自恋专业知识的临床医生准确预测 PNI 浮夸和脆弱性与正常和病理性人格特质和精神病理学的相关性的程度来评估。对比预测 r（cv）系数提供了临床医生预测准确性的总体指标，通过检查各组之间的系统差异可以更详细地阐述该指标。总体而言，新手和专家临床医生通常能够预测准则相关性，但也存在一些例外（例如，与预测相反，病理性自恋与治疗抵抗呈负相关）。这些结果进一步证明了 PNI 测量的自恋浮夸和自恋脆弱性结构的有效性和实用性。
