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. Copyright © 2015 John Wiley & Sons, Ltd.
