School-aged children who present for psychotherapy are often very perplexing. Their symptoms are clear and concerning, but the reasons for the symptoms are obscure. The parents describe the progress of the symptoms, but usually have little understanding of the process that resulted in problems. The children are even less informative and, when the symptoms are quite severe, children's communication may become almost inscrutable. Nevertheless, astute clinicians have often felt the children had a coherent story to tell if we just knew how to listen. The papers presented in this Special Section of Clinical Child Psychology and Psychiatry (CCPP) describe the process and outcomes of a series of studies exploring the reliability, validity, and utility of the School-aged Assessment of Attachment (SAA). The SAA uses children's narratives about threats that school-aged children fear (and sometimes experience) and the self-protective attachment strategies that they organize to protect and comfort themselves. Clinicians need an assessment that discriminates within the group of risk children and does so by adding to what is already known (as opposed to corroborating the known risk/non-risk status of the child). Furthermore, the new information must have implications for more precise treatment than would have been offered without the assessment. This is the issue of utility. Researchers need an assessment with construct validity (as opposed to the face validity of calling it "attachment") and reliability among coders. Children need an assessment that engages them in ways that are suitable for their age and development, and that addresses their concerns. However, the two best validated assessments of attachment (the Ainsworth Strange Situation and George/Main Adult Attachment Interview) are inappropriate for school-aged children. Short separations do not elicit attachment strategies in school-aged children and Adult Attachment Interview (AAI)-style questions, aimed at integrating early and current events with their implications for the self in the present, are beyond children's maturational capacity. Although a number of approaches have been offered for the school years, none has yet achieved wide acceptance, nor has any been validated sufficiently to justify such acceptance. Constructing a developmentally attuned and clinically informative assessment Attachment and school-aged children's development In infancy, attachment is person-specific, that is, the attachment between an infant and a specific parent. By adulthood, attachment can be integrated to a generalized pattern that adults use in many 588650C CP0010.
