However, the instances of that ability are rare.The name of the disorder emphasizes problems with attachment but the criteria include symptoms such as failure to thrive, a lack of developmentally appropriate social responsiveness, apathy, and onset before 8 months. Assessment tools
There is as yet no universally accepted diagnostic protocol for reactive attachment disorder. Often a range of measures is used in research and diagnosis. Recognized assessment methods of attachment styles, difficulties or disorders include the Strange Situation Procedure (devised by developmental psychologist Mary Ainsworth), the separation and reunion procedure and the Preschool Assessment of Attachment, the Observational Record of the Caregiving Environment, the Attachment Q-sort and a variety of narrative techniques using stem stories, puppets or pictures. For older children, actual interviews such as the Child Attachment Interview and the Autobiographical Emotional Events Dialogue can be used. Caregivers may also be assessed using procedures such as the Working Model of the Child Interview.More recent research also uses the Disturbances of Attachment Interview (DAI) developed by Smyke and Zeanah (1999). The DAI is a semi-structured interview designed to be administered by clinicians to caregivers. It covers 12 items, namely "having a discriminated, preferred adult", "seeking comfort when distressed", "responding to comfort when offered", "social and emotional reciprocity", "emotional regulation", "checking back after venturing away from the care giver", "reticence with unfamiliar adults", "willingness to go off with relative strangers", "self-endangering behavior", "excessive clinging", "vigilance/hypercompliance" and "role reversal".
This method is designed to pick up not only RAD but also the proposed new alternative categories of disorders of attachment. Causes
Although increasing numbers of childhood mental health problems are being attributed to genetic defects, reactive attachment disorder is by definition based on a problematic history of care and social relationships. Abuse can occur alongside the required factors, but on its own does not explain attachment disorder. It has been suggested that types of temperament, or constitutional response to the environment, may make some individuals susceptible to the stress of unpredictable or hostile relationships with caregivers in the early years. In the absence of available and responsive caregivers it appears that most children are particularly vulnerable to developing attachment disorders.While similar abnormal parenting may produce the two distinct forms of the disorder, inhibited and disinhibited, studies show that abuse and neglect were far more prominent and severe in the cases of RAD, disinhibited type. The issue of temperament and its influence on the development of attachment disorders has yet to be resolved. RAD has never been reported in the absence of serious environmental adversity yet outcomes for children raised in the same environment are the same.In discussing the neurobiological basis for attachment and trauma symptoms in a seven-year twin study, it has been suggested that the roots of various forms of psychopathology, including RAD, borderline personality disorder (BPD), and post-traumatic stress disorder (PTSD), can be found in disturbances in affect regulation.
