Association between psychological distress and information needs on illness, treatment, follow up, and late effects. Mean differences in T-scores and 95% confidence intervals on the three BSI-18 scales (somatization, depression, and anxiety) between survivors with information needs on illness (black diamond), treatment (white triangle), follow-up (gray square), and late effects (dotted circle) versus survivors without information needs. Higher scores indicate higher distress. Means were adjusted for sex, age, language, and diagnosis.
