TI - The Experiences in Close Relationships-Revised questionnaire: factorial structure, reliability and a short version of the scale in a Polish sample
	 
AB - 
	The Experiences in Close Relationships-Revised is one of the most popular self-report instruments assessing adult attachment in the sphere of avoidance and anxiety. Although the scale is used in Poland, its psychometric properties are not sufficiently documented. In the study, we set out to: estimate the psychometric properties of the scale, controlling for the common method variance (method bias); and introduce a short version of the scale. The sample was composed of 781 adults between the age of 16 and 81. The results of the confirmatory factor analysis supported two-factorial ECR-R structure indicating problems with low factor loadings, which deteriorated even more after controlling for the common method variance. On the basis of the content of the items and their psychometric properties we proposed a short 16-item form of the ECR-R scale which revealed a good model fit and factor loadings. However, the effects of the common method variance on factor loadings and the avoidance-anxiety relation were found to be substantial. The results revealed that the relation between avoidance and anxiety was due to the shared method variance and not to the attachment itself. The issues concerning the construction of attachment self-report scales are discussed along with practical implications for the further use of the ECR-R scale in Poland, named as the DBZ-R (36-items) or the DBZ-RS (the short version).
