The measurement invariance of the Experiences in Close Relationships (ECR) questionnaire was investigated across four samples of non-clinical subjects (N = 222), dermatological patients (N = 458), psychiatric inpatients (N = 156), and patients with drug-resistant epilepsy (N = 101). The results provided evidence of configural, metric, and scalar invariance across groups. Overall, our findings provide further support to the reliability and validity of the ECR.
本研究考察了非临床受试者（N=222）、皮肤科患者（N=458）、精神科住院患者（N=156）和耐药性癫痫患者（N=101）四个样本中亲密关系经历问卷（ECR）的测量不变性。结果表明，组间具有构念不变性、度量不变性和标度不变性。总的来说，我们的研究结果进一步支持了 ECR 的信度和效度。
