Abstract
One of the actual tendencies within Attachment Theory is about the understanding of atypical trajectories in development of attachment, specifi cally referred to Disorganized Attachment (D attachment). Two decades of research about antecedents and consequents of this pattern of attachment have spawned a huge amount of empirical and theoretical knowledge. However, parental etiological models who seek to explain processes and mechanisms of D attachment have shown contradictory and incomplete evidence. Due to the important contribution that this kind of models can have for infant and child interventions, this paper seek to review existing model in order to clarify the state of the art of this important research and clinical subject.
