Correlates of self-reported colorectal cancer screening accuracy in a multi-specialty medical group practice.

Purpose: We assessed whether accuracy of self-reported screening for colorectal cancer (CRC) varied by respondent characteristics or healthcare utilization.

Methods: From 2005 to 2007, 857 respondents aged 51 - 74 were recruited from a multi-specialty medical group practice to answer a questionnaire about their CRC screening (CRCS) behaviors. Self-reports were compared with administrative and medical records to assess concordance, sensitivity, specificity, and report-to-records ratios for overall CRCS (fecal occult blood test, sigmoidoscopy, and/or colonoscopy).

Gender differences in colorectal cancer incidence in the United States, 1975-2006.

Background: Gender differences have been documented among patients diagnosed with colorectal cancer (CRC). It is still not clear, however, how these differences have changed over the past 30 years and if these differences vary by geographic areas. We examined trends in CRC incidence between 1975 and 2006.

Is the accuracy of self-reported colorectal cancer screening associated with social desirability?

Background: Self-reported cancer screening behaviors are often overreported and may lead to biased estimates of prevalence and of subgroup differences in screening. We examined whether the tendency to give socially desirable responses was associated with concordance between self-reported colorectal cancer (CRC) screening behaviors and medical records.

Methods: Primary care patients (n = 857) age 50 to 74 years completed a mail, face-to-face, or telephone survey that assessed CRC screening and social desirability measured by a short version of the Marlowe-Crowne scale.

Accuracy of self-reported reason for colorectal cancer testing.

Assessment of accuracy of self-reported reason for colorectal cancer testing has been limited. We examined the accuracy and correlates of self-reported reason (screening or diagnosis) for having a sigmoidoscopy or colonoscopy. Patients who had received at least one sigmoidoscopy or colonoscopy within the past 5 years were recruited from a large multispecialty clinic in Houston, TX, between 2005 and 2007.

Cervical cancer screening among college students in ghana: knowledge and health beliefs.

Background: Cervical cancer is the most incident cancer and the leading cause of cancer mortality in women in Ghana. Currently, little is known about Ghanaian women's knowledge and beliefs about cervical cancer screening, yet this information is essential to the success of cervical cancer screening programs. Therefore, the purpose of this study was to describe the knowledge and beliefs of female university college students in Ghana.
