Outcome Measures

Primary Outcomes (2)

  • Change in Correct Responses Regarding Knowledge Related to Colorectal Cancer Risk, Prevention, and Screening

    A pre-test and post-test are conducted with participants to assess changes in knowledge related to key learning outcomes expected from the educational intervention (assessed via 14 true/false and multiple-choice questions, reported as a percent change in points). An increased % change in points represents increased knowledge of each survey question and a value of 0 indicates knowledge did not change (a negative value would indicate decreased knowledge). % change is a unique number that was calculated as the difference between the % answering correctly after the intervention minus the % correct before the intervention; it is representative of the entire data set and not calculated on an individual participant level. P values (\<0.05) are based on chi-square tests. Each row represents a unique survey question evaluating the topic listed in the row title.

    pre-test administered immediately before educational intervention; post-test administered immediately after the educational intervention on day 1.

  • Change in Colorectal Cancer Screening and Other Risk Behavior Intentions

    A pre-test and post-test are conducted to assess behavioral intention related to five prevention and screening behaviors (assessed via 5 questions on a 5-point Likert scale: strongly agree (5), agree, unsure, disagree, strongly disagree(1). The values reported represent the difference between pre-intervention and post-intervention scores, calculated as a unique number for the total responding participants (not calculated individually). A positive change represents increased intent. Each row represents a unique survey question evaluating the topic listed in the row title.

    pre-test administered immediately before educational intervention; post-test administered immediately after educational intervention on day 1

Study Arms (1)

Experimental Arm 1

EXPERIMENTAL

Participants who meet eligibility criteria will be able to enroll and participate on-line, with some participating in online or telephone survey follow-up.

Other: Online educational video and website module

Interventions
