The ECR is a 36-item measure of adult attachment style. The scale comprises two 18-item subscales measuring two attachment constructs: attachment-anxiety and attachment-avoidance, which tends to have excellent internal consistency reliability [31]. Items are rated on a 7-point Likert scale. The ECR was only applied to Study 1. Thirteen participants (2.6%) skipped one item, and these items were replaced by the subscale mean. One participant skipped ten items (27%), and as such excluded from the analysis of this measure (Cronbach’s α = avoidance = .95 and anxiety = .93).
