Of 2208 women recruited to the START QOL study, 35 % reported clinically relevant levels of anxiety and/or depression pre-RT; there was no significant change in these proportions over time. However, 75 % women with high baseline anxiety recorded further high scores over time whilst one in six had high scores at every follow-up point. Depression showed a similar pattern with lower frequencies at all time points; very few with initial normal scores developed clinically relevant anxiety or depression over time. Lower educational level predicted worse anxiety and depression over time; younger age predicted worse anxiety and chemotherapy predicted worse depression. Scores in the borderline or case range for anxiety or depression at baseline were both significantly associated with worse mood states over 5 years.
These findings indicate the course of anxiety and depression in women with specific risk factors. This subgroup of patients requires greater clinical attention.
