Validation of the 14-item short form of the Slovak version of the Experiences in Close Relationships Revised Questionnaire

Abstract

Aims. The attachment formed in early childhood affects an individual’s mental and physical health. The aim of the study was to assess the psychometric properties of the Slovak version of the ECR-R questionnaire designed to detect attachment in adulthood, to create a shorter version, and to examine the sociodemographic differences in anxiety and avoidance among Slovak respondents. Sample, settings, and methods. In a cross-sectional study with a representative sample of the adult Slovak population (N=1018, age 46.24, SD 16.56, 48.7% men), data were collected using the Slovak translation of the ECR-R questionnaire. The Slovak version of the Relationship Questionnaire (RQ) was used to assess the convergence validity. Results. The data of the psychometric analysis of the shortened version of the Close Relationship Questionnaire, the ECR-R-SK-14, indicate its better suitability for measuring relationship in adulthood compared to the ECR-R-16 version. Convergent validity was confirmed. Sociodemographic differences in individual groups of the Slovak population, which were expanded to include subjectively perceived loneliness in the last year of life, were described. Summary. The ECR-R questionnaire and its shorter version, the ECR-R-SK-14, are suitable tools for measuring relationships in adulthood, whether scientific or clinical. Limitations. The complete version of the ECR-R questionnaire can be difficult for some respondents to understand due to a large number of reversely formulated questions.
