 Although attachment theory has become a major scientific theory of socioemotional development with one of the broadest, deepest research lines in modern psychology, attachment theory has, until recently, been less clinically applied than theories with far less empirical support.This may be partly due to lack of attention paid to clinical application by Bowlby himself and partly due to broader meanings of the word 'attachment' used amongst practitioners.It may also be partly due to the mistaken association of attachment theory with the pseudo-scientific interventions misleadingly known as attachment therapy.
