The ECR-RS questionnaire has limited utility in OHCA survivors due to item-level inconsistencies and floor effects, highlighting the need for a revised instrument.
Aim: To explore the construct validity of the 'Experience in Close Relationships - Relationship Structures'-questionnaire (ECR-RS) in a population of out-of-hospital cardiac arrest (OHCA) survivors. Objectives were to (i) describe item- and scale-level response patterns, and (ii) evaluate the preliminary construct validity of the ECR-RS, including its dimensional (structural), known-groups, and convergent validity. Methods: s. Known-group validity was tested using a priori hypotheses, Spearman's correlations, and Mann-Whitney U tests. Convergent validity was evaluated by correlating ECR-RS total scores with HADS and SF-12 MCS. Results: = 0.88) and improved when problematic items were excluded. Known-group hypotheses were not supported. Anxious attachment correlated moderately with symptoms of anxiety and depression and was inversely correlated with mental health scores. Conclusion: The ECR-RS demonstrated partial construct validity among OHCA survivors, but item-level inconsistencies and pronounced floor effects limit its utility. Findings highlight the need for a revised instrument better suited to post-cardiac arrest relational and psychological dynamics.
