Research
Research from the late 1990s indicated there were disorders of attachment not captured by DSM or ICD and showed that RAD could be diagnosed reliably without evidence of pathogenic care, thus illustrating some of the conceptual difficulties with the rigid structure of the current definition of RAD. Research published in 2004 showed that the disinhibited form can endure alongside structured attachment behavior (of any style) towards the childs permanent caregivers.Some authors have proposed a broader continuum of definitions of attachment disorders ranging from RAD through various attachment difficulties to the more problematic attachment styles. There is as yet no consensus, on this issue but a new set of practice parameters containing three categories of attachment disorder has been proposed by C.H. Zeanah and N. Boris. The first of these is disorder of attachment, in which a young child has no preferred adult caregiver. The proposed category of disordered attachment is parallel to RAD in its inhibited and disinhibited forms, as defined in DSM and ICD. The second category is secure base distortion, where the child has a preferred familiar caregiver, but the relationship is such that the child cannot use the adult for safety while gradually exploring the environment. Such children may endanger themselves, cling to the adult, be excessively compliant, or show role reversals in which they care for or punish the adult. The third type is disrupted attachment.
The subsequent development of higher-order self-regulation is jeopardized and the formation of internal models is affected. Consequently, the "templates" in the mind that drive organized behavior in relationships may be impacted. The potential for "re-regulation" (modulation of emotional responses to within the normal range) in the presence of "corrective" experiences (normative caregiving) seems possible. Diagnosis
RAD is one of the least researched and most poorly understood disorders in the DSM. There is little systematic epidemiologic information on RAD, its course is not well established and it appears difficult to diagnose accurately. There is a lack of clarity about the presentation of attachment disorders over the age of five years and difficulty in distinguishing between aspects of attachment disorders, disorganized attachment or the consequences of maltreatment.According to the American Academy of Child and Adolescent Psychiatry (AACAP), children who exhibit signs of reactive attachment disorder need a comprehensive psychiatric assessment and individualized treatment plan. The signs or symptoms of RAD may also be found in other psychiatric disorders and AACAP advises against giving a child this label or diagnosis without a comprehensive evaluation. Their practice parameter states that the assessment of reactive attachment disorder requires evidence directly obtained from serial observations of the child interacting with his or her primary caregivers and history (as available) of the childs patterns of attachment behavior with these caregivers. It also requires observations of the childs behavior with unfamiliar adults and a comprehensive history of the childs early caregiving environment including, for example, pediatricians, teachers, or caseworkers.
