Testing the incremental value of a separate measure for secure attachment relative to a measure for attachment anxiety and avoidance in middle childhood and early adolescence

Research on attachment in middle childhood and early adolescence has typically relied on either unidimensional measures of attachment security (versus insecurity) or on differentiated measures of attachment anxiety and avoidance. This study addressed the question whether there is a need to add an explicit measure of security when operationalizing parent-child attachment in terms of anxiety and avoidance. Both dimensional (i.e., regression analyses) and person-centered analyses (i.e., cluster analysis) are used in this study (N = 276, 53% boys, mean age = 10.66) to examine the incremental value of a scale for attachment security (in this study, the Security Scale) in addition to a scale for attachment anxiety and avoidance (in this study, the Experiences in Close Relationships Scale Revised – Child version; ECR-RC). The present results suggest that an assessment of anxious and avoidant attachment (using the ECR-RC) may suffice to capture the quality of parent-child attachment in middle childhood and early adolescence
