Professor Heather Henderson, a co-author of the study said, “We now understand that infants and young children with an inhibited temperament who also have insecure early attachment relationships are most likely to become socially anxious teens -- especially boys."
Attachment is especially vital, the researchers found, when a baby shows behavioural inhibition or shyness to new situations or people.
This is the first long-term study of the combined influence of attachment and behavioural inhibition as predictors of teen anxiety.
