Effectiveness of a Multimedia-Based Educational Intervention for Improving Colon Cancer Literacy in Screening Colonoscopy Patients

Abstract

A knowledge deficit of colon cancer-related concepts is frequently observed in patients undergoing screening colonoscopy. Multimedia-based educational intervention was an effective, satisfying strategy for addressing cancer-specific knowledge deficit in laypersons.

Assessment of Colon Cancer Literacy in Screening Colonoscopy Patients: A Validation Study

“…Furthermore, patients undergoing colon cancer screening may not fully understand the implications of a colon cancer diagnosis [22]. The ACCL may help to identify colon cancer patients who require educational intervention in order to maximize their colon cancer treatment and outcome and, also, may build a foundation for directed patient-physician discussion.…”

“…Scores for NVS range from 0 to 6 [16]. The ACCL was a self-administered instrument consisting of 10 true-false statements, including basic definitions of cancer-related terms, such as malignancy, metastasis, adjuvant therapy, and treatment implications [22,23]. The themes that were tested in the ACCL include disease prevalence, causative factors, polyps, surgical management, other cancer treatment modalities, such as chemotherapy and radiotherapy, terms such as invasive, malignant, metastasis.…”

“…For the ACCL, a priori we assigned scores of 7-10 as adequate literacy and scores of 0-6 as possible limited literacy based up on previous research [22,23]. Categorical outcome variables (limited or adequate literacy) were compared using c 2 tests to calculate the sensitivity and specificity.…”

“…Prior research in our group has demonstrated the effectiveness of such a module about colon cancer using a 10-question survey [21,22]. The aim of the present study is to validate colon cancer-specific health literacy assessment tool: ''Assessment of Colon Cancer Literacy (ACCL)'', against a standard measure of health literacy, the NVS.…”

Integration of Valley Orientation Distribution for Polyp Region Identification in Colonoscopy

“…Colon cancer's survival rate depends on the stage in which it is detected, decreasing from rates higher than 95% in the first stages to rates lower than 35% in stages IV and V [9]; hence the importance of detecting it early by using screening techniques, such as colonoscopy [4].…”
