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 child's patterns of attachment behavior with these caregivers. It also requires observations of the child's behavior with unfamiliar adults and a comprehensive history of the child's early caregiving environment including, for example, pediatricians, teachers, or caseworkers. In the US, initial evaluations may be conducted by psychologists, psychiatrists, Licensed Marriage and Family Therapists, Licensed Professional Counselors, specialist Licensed Clinical Social Workers or psychiatric nurses. In the UK, the British Association for Adoption and Fostering (BAAF) advise that only a psychiatrist can diagnose an attachment disorder and that any assessment must include a comprehensive evaluation of the child's individual and family history. According to the AACAP Practice Parameter (2005) the question of whether attachment disorders can reliably be diagnosed in older children and adults has not been resolved. Attachment behaviors used for the diagnosis of RAD change markedly with development and defining analogous behaviors in older children is difficult. There are no substantially validated measures of attachment in middle childhood or early adolescence. Assessments of RAD past school age may not be possible at all as by this time children have developed along individual lines to such an extent that early attachment experiences are only one factor
