Screening guidelines for colorectal cancer recommend annual fecal occult blood (FOB) testing for adults aged 50 years and older.
Self-reported history of screening is frequently the sole source of data available to researchers and clinicians.
This study validated FOB testing in a sample of 1,021 older women.
Testing rates based on self-reported data exceeded rates based on computerized laboratory records by 13.9%. Agreement was moderate (kappa=0.52 ; 95% confidence interval 0.47,0.58).
Sensitivity was 0.92 and specificity 0.58.
Logistic regression analysis showed that older age and physician encouragement for FOB testing were associated with accurate recall (p<0.05).
Self-report is the most commonly available information about the occurrence and timing of cancer detection procedures.
These data suggest cautious use of self-reported screening by FOB for clinical decision making and for research and surveillance.
