The compilation of aspects of a childs life aids in capturing a multi-dimensional view of the childs life.Additionally, while much research has been done in efforts to further understand separation anxiety in regards to the relationship between infants and their caregivers, it was behavioral psychologist, Mary Ainsworth, who devised a behavioral evaluation method, The Strange Situation (1969), which, at the time, was considered to be the most valuable and famous body of research in the study of separation anxiety. The Strange Situation process assisted in evaluating and measuring the individual attachment styles of infants between the ages of 9 and 18 months. In this observational study an environment is created that fluctuates between familiar and unfamiliar situations that would be experienced in everyday life. The variations in stressfulness and the childs responses are observed and, based on the interaction behavior that is directed towards the caregiver, the infant is categorized into one of four different types of attachment styles: 1. Secure, 2. Anxious-avoidant, insecure, 3. Anxious-ambivalent/resistant, insecure and 4. Disorganized/disoriented.Clinicians may utilize interviews as an assessment tool to gauge the symptomatic occurrences to aid in diagnosing SAD. Interviews may be conducted with the child and also with the attachment figure.
Background
The origins of separation anxiety disorder stem from attachment theory which has roots in the attachment theories both of Sigmund Freud and John Bowlby. Freuds attachment theory, which has similarities to learning theory, proposes that infants have instinctual impulses, and when these impulses go unnoticed, it traumatizes the infant. The infant then learns that when their mother is absent, this will be followed by a distressing lack of gratification, thus making the mothers absence a conditioned stimulus that triggers anxiety in the infant who then expects their needs to be ignored. The result of this association is that the child becomes fearful of all situations that include distance from their caregiver. John Bowlbys attachment theory also contributed to the thinking process surrounding separation anxiety disorder. His theory is a framework in which to contextualize the relationships that humans form with one another. Bowlby suggests that infants are instinctively motivated to seek proximity with a familiar caregiver, especially when they are alarmed, and they expect that in these moments they will be met with emotional support and protection. He poses that all infants become attached to their caregivers, however, there are individual differences in the way that these attachments develop. There are 4 main attachment styles according to Bowlby; secure attachment, anxious-avoidant attachment, disorganized attachment, and anxious-ambivalent attachment. Anxious-ambivalent attachment is most relevant here because its description, when an infant feels extreme distress and anxiety when their caregiver is absent and does not feel reassured when they return, is very similar to SAD.
