The paradox of insecure attachment and depressive symptoms across the lifespan: Towards an integrative view
Attachment theory has long argued that insecure attachment patterns are associated with vulnerability to psychopathology in general, and depressive symptoms in particular. However, accumulating evidence from the past four decades, summarized in three large meta-analyses (each assessing over 4000 subjects) that evaluated the link between insecure attachment and depressive symptoms at different developmental stages, suggested paradoxical results. Specifically, children with histories of deactivating (i.e., insecure-avoidant) but not hyperactivating (i.e., insecure-resistant) attachment patterns in infancy and early childhood showed elevated depressive symptoms. In contrast, adolescents and adults with hyperactivating (i.e., insecure-preoccupied) but not deactivating (i.e., insecure-dismissing) attachment classifications showed elevated depressive symptoms. In this paper, we summarize findings from three large meta-analyses across different developmental periods, and highlight the contradicting meta-analytic findings regarding the link between attachment and depressive symptoms across human development. On top of presenting some methodological issues regarding the constructs and measurements of depressive symptoms across the lifespan, we propose a developmentally integrative explanation as to why the two insecure attachment patterns may be differentially linked to depression at different developmental stages. Lastly, we offer future research directions to empirically examine the link between insecure attachment and depressive symptoms across the lifespan.
