She has now retired from clinical practice, but continues to run training workshops and to make the products of research generally available through her writing. Her books include Overcoming Social Anxiety and Shyness, and Psychology: A Very Short Introduction (co-authored with Freda McManus). Nick qualified as a clinical psychologist in 1996.
