The , 11th edition includes a new personality disorder diagnosis, in light of growing concerns of the categorical personality disorder diagnoses. The purpose of the current study was to examine the reliability and validity of the severity dimension of the new , 11th edition diagnosis, through multi-method assessment.
In a community mental health sample ( = 311), we examined the interrater reliability of the severity diagnosis and evaluated the diagnosis against self-report measures of dimensional personality pathology and psychopathology constructs and traditional categorical and informant-report measures.
Intraclass correlations indicated 'excellent' reliability of the diagnostic ratings. Large associations were observed between the , 11th edition clinician diagnosis and overall impairment measures. Generally, the , 11th edition clinician diagnosis exhibited largest associations with measures of internalising dysfunction, and more variable associations with interpersonal and externalising impairment. The , 11th edition clinician diagnosis showed a large association with borderline personality disorder symptom scores and moderate associations with Paranoid, Schizoid and Avoidant personality disorder scores. Similar patterns emerged of the associations between the , 11th edition personality disorder diagnosis with self-report and informant-report measures, although the associations were larger with self-report measures.
These findings provide promising initial evidence for the reliability and validity of the new , 11th edition personality disorder diagnosis, indicating that the new conceptualisation of personality disorders may address issues within the categorical model.
第 11 版包括了一个新的人格障碍诊断，这是鉴于对分类人格障碍诊断的日益关注。本研究的目的是通过多方法评估来检验新的第 11 版诊断严重程度维度的可靠性和有效性。
在一个社区心理健康样本（n=311）中，我们检验了严重程度诊断的评分者间信度，并将该诊断与多维人格病理和精神病理学结构的自我报告测量以及传统的分类和知情者报告测量进行了比较。
组内相关系数表明诊断评分具有“极好”的可靠性。第 11 版临床医生诊断与总体损伤测量之间存在较大关联。总体而言，第 11 版临床医生诊断与内化功能障碍的测量指标关联最大，与人际和外化损伤的关联则更具变异性。第 11 版临床医生诊断与边缘型人格障碍症状评分有很大关联，与偏执型、分裂型和回避型人格障碍评分有中等关联。与自我报告和知情者报告测量指标之间的关联也呈现出类似的模式，尽管与自我报告测量指标的关联更大。
这些发现为新的第 11 版人格障碍诊断的可靠性和有效性提供了初步的有希望的证据，表明人格障碍的新概念化可能解决了分类模型中的问题。
