Insecure Attachment Orientation in Adults and Children and Negative Attribution Bias: A Meta-Analysis.

Abstract

This is the first meta-analysis to synthesize the literature on insecure attachment and negative attribution bias (NAB) from both developmental and social/personality attachment traditions. This meta-analysis is important because extant studies report inconsistent associations, making it difficult to draw conclusions about the nature of these associations. Based on 41 samples (N = 8,727) from 32 articles, we specify and compare the effect sizes of these associations across studies. Results confirmed positive associations between NAB and anxious and avoidant attachment dimensions and an insecure composite, with a medium effect size. Correlations were moderated by age group, type of attachment measurement, and cultural background. Our findings advance knowledge and build on attachment and attribution theories, reconcile mixed findings, and inform the development of NAB interventions. Important gaps in the literature are revealed that will inspire future research.
