Parent-child concordance for separation anxiety: a clinical study.

There is tentative evidence supporting a familial basis for separation anxiety. The present study aimed to examine parent–child concordance for that subtype of anxiety. Fifty-four children diagnosed with anxiety disorders and their parents (54 mothers and 29 fathers) were recruited from two juvenile anxiety clinics. Sixty-three percent of children diagnosed with juvenile separation anxiety disorder had at least one parent who suffered from the putative adult variant of the disorder (odds ratio=11.1) (P<0.001). Affected parents reported high levels of separation anxiety in their own childhoods. Juvenile separation anxiety disorder in children was not associated with any other parental diagnosis. The small sample size and other potential biases caution against definitive conclusions being drawn, but the present data add to existing evidence that separation anxiety may aggregate in families.
