Reactive Attachment Disorder and attachment theory from infancy to adolescence: review, integration, and expansion

Abstract

In reviewing the preceding articles, I emphasize the predominance of relational theories in the study of development as a way of demonstrating the evolutionary and relational extremity of reactive attachment disorder (RAD). The lack (or distortion?) of mutuality, RAD's defining feature, has implications for all aspects of development, not least of which is self-regulation. I review each article in this special issue, emphasizing important features, integrating across studies, expanding their links to attachment theory, and recommending future directions. Finally, I conduct two meta-analyses of the samples in this special issue, one meta-analysis addressing convergent validity of RAD assessment instrumentation developed by authors represented here and the other addressing the links between RAD and internalizing and externalizing behaviors. This special issue exploits the disaggregation of reactive attachment and disinhibited social engagement disorders to move the field forward in remarkable ways, both methodologically and substantively.
