Objective: To assess the relationships between shy-inhibited temperament in
childhood and anxiety problems in early adolescence using a prospective, l
ongitudinal data set from a large community sample. Method: Relationships b
etween shyness ratings on age-appropriate temperament scales and anxiety pr
oblems were analyzed, looking both forward and backward in time from infanc
y to adolescence. Results: Forty-two percent of children rated as shy on 6
or more occasions over 8 surveys in childhood had anxiety problems in adole
scence, compared with 11% who were never shy. Persistence of shyness and it
s presence in middle childhood increased risk for anxiety. A highly reactiv
e temperament added to shyness did not increase the risk for anxiety. Few c
hildren with an anxiety diagnosis in early adolescence had a history of shy
ness. Conclusions: Prediction from childhood shyness to adolescent anxiety
disorder is modest but clinically meaningful in a community sample. However
, most shy children did not develop an anxiety disorder and most adolescent
s with anxiety disorders had not been especially shy.
