Experiences in Close Relationships Scale-Short Form ECR-12

Abstract

The Experiences in Close Relationship Scale-Short Form (ECR-12) is a concise, 12-item self-report Psychological Scale designed to measure individual differences in adult attachment across two primary dimensions: attachment anxiety and attachment avoidance. Developed by Wei, Russell, and Vogel in 2007, the ECR-12 serves as an efficient alternative to the original 36-item Experiences in Close Relationship Scale (ECR), providing researchers and clinicians with a reliable and valid tool for assessing core features of Adult Attachment styles within the context of romantic relationships.

Purpose

The primary purpose of the ECR-12 is to provide a brief yet psychometrically sound measure of the two key dimensions characterizing adult attachment: anxiety concerning abandonment and availability, and avoidance of intimacy and dependence. This short form was developed to reduce respondent burden and improve efficiency in research settings, particularly in studies requiring repeated measures or inclusion within larger test batteries, while maintaining the strong empirical foundation of the original ECR.

The scale is intended for use in studies examining how relational patterns influence psychological well-being, relationship satisfaction, and interpersonal functioning. It helps researchers categorize individuals along the two continuous dimensions of attachment, which are central tenets of contemporary Attachment Theory.

Construct

The ECR-12 operationalizes the continuous, two-dimensional model of Attachment Theory as applied to adults in close relationships. The two constructs measured are:

• Attachment Anxiety: This dimension reflects the degree to which an individual worries about their partner’s availability, responsiveness, and commitment. High scores indicate a preoccupation with relationships, fear of rejection or abandonment, and excessive need for reassurance.
• Attachment Avoidance: This dimension reflects the degree to which an individual distrusts their partner’s goodwill and prefers emotional distance or self-reliance. High scores indicate discomfort with intimacy, reluctance to depend on others, and efforts to maintain emotional separation.

These two dimensions are considered orthogonal, meaning they operate independently, allowing researchers to classify individuals into the four classic attachment styles (Secure, Preoccupied, Dismissing-Avoidant, and Fearful-Avoidant) based on their combined scores.

Validity

The original validation study demonstrated robust evidence for the ECR-12’s validity. Construct validity was established through confirmatory factor analysis, which supported the hypothesized two-factor structure (Anxiety and Avoidance). Convergent validity was supported by significant correlations between the ECR-12 subscales and measures of related constructs, such as relationship satisfaction, self-esteem, and general distress. For example, high attachment anxiety is typically associated with lower relationship satisfaction, while high avoidance is associated with poorer disclosure behavior. Discriminant validity was also confirmed, showing that the ECR-12 subscales were distinct from, but related to, general personality traits, indicating that the scale measures a unique relational construct.

Reliability

The ECR-12 exhibits excellent internal consistency, which is a key measure of reliability. In the validation study, both the Anxiety and Avoidance subscales demonstrated high Cronbach’s alpha coefficients, comparable to those found in the original, longer ECR scale. This indicates that the 6 items comprising each subscale consistently measure their respective underlying Psychological Construct. The stability of the scores over time (test-retest reliability) has also been supported in subsequent research, confirming that the ECR-12 provides stable measurements of trait-like attachment orientation.

Factor Analysis

The structure of the ECR-12 was rigorously tested using confirmatory factor analysis during its development. This analysis confirmed the presence of a distinct, two-factor model, perfectly mirroring the theoretical structure of adult attachment. The two factors—Attachment Anxiety and Attachment Avoidance—were found to be moderately correlated but empirically distinct, supporting the use of two separate subscale scores. This clear Factor Structure is critical, as it ensures that the brief 12-item scale accurately captures the complexity of the two-dimensional attachment space.
