Patients with personality disorders represent maladaptive attachment strategies, influencing the quality of their interpersonal relationships. Within these patient populations, it is important to have a measure, easily applied, to assess such strategies. A widely used instrument is Experiences in Close Relationships (ECR), assessing two constructs called avoidance and anxiety. Lately, two short forms of ECR have been proposed, called ECR-S and ECR-N12. The aim of this study is to investigate the psychometric properties of the Norwegian @version of ECR and its two short forms in a sample of patients with mainly personality disorders. An internal consistency and confirmatory factor analysis of ECR, ECR-S and ECR-N12 from 495 patients was conducted, as well as an exploratory factor analysis of ECR. The internal consistency of ECR was found questionable. Confirmatory factor analysis revealed a poor model fit based on ECR and ECR-S. The ECR-N12 revealed a mediocre fit, indicating a potential for improvement. Exploratory factor analysis indicated two different aspects of avoidance and three aspects of anxiety. This five-factor solution was called ECR-FF. Inferences from scores based on ECR should be derived with care. A revision of ECR and ECR-N12 is warranted, and further studies are needed to investigate the validity of ECR-FF.
患有个性障碍的患者表现出适应不良的依恋策略，这会影响他们人际关系的质量。在这些患者群体中，拥有一种易于应用的测量方法来评估此类策略非常重要。一种广泛使用的工具是亲密关系经历量表（ECR），它评估两种称为回避和焦虑的结构。最近，有人提出了ECR的两种简短形式，即ECR-S和ECR-N12。本研究的目的是在主要患有个性障碍的患者样本中，调查挪威版ECR及其两种简短形式的心理测量特性。对495名患者的ECR、ECR-S和ECR-N12进行了内部一致性和验证性因素分析，以及对ECR进行了探索性因素分析。发现ECR的内部一致性存在问题。验证性因素分析显示基于ECR和ECR-S的模型拟合不佳。ECR-N12显示拟合一般，表明有改进的潜力。探索性因素分析表明回避有两个不同方面，焦虑有三个方面。这个五因素解决方案被称为ECR-FF。基于ECR得分得出的推论应谨慎得出。有必要对ECR和ECR-N12进行修订，还需要进一步研究来调查ECR-FF的有效性。
