| Mean (95% CI) | Mean (95% CI) | Beta (95% CI) | P value | ||

Score ranges for each psychological outcome measure are: cancer worry (7-29), anxiety (0–21), depression (0–21); models adjusted for gender, age, ethnicity, education, employment status, marital status and smoking status. For psychological outcomes at T1 and T2, the models were also adjusted for T0 outcomes.
