Note. Not all demographics add up to 100% due to missing data. Note. Construct validity was assessed by comparing the 'expert' group with 'controls' and sensitivity to change was assessed by comparing the 'intervention' group with the 'controls' a Shows those responding 'correctly' b Total knowledge score' = Warning signs (prompted) + risk factors (prompted) +age at risk + bowel screening programme + age people first invited for screening + lifetime risk * indicates a statistically significant difference (P < 0.05) compared with control ** indicates a statistically significant difference (P < 0.01) compared with control *** indicates a statistically significant difference (P < 0.001) compared with control |
