Liver Cancer Community Education

Primary outcomes

1. Change in Mean Liver Cancer Knowledge

   Time frame: Baseline, 30 minutes

   Liver cancer knowledge will be measured through four true/false items. Responses will be summed for a total liver cancer knowledge score. Score ranges run from 0-4, with higher scores indicating more knowledge. Change in knowledge is measured by subtracting baseline knowledge score from the post-intervention knowledge score. Change scores may range from -4 to 4, with positive scores indicating an increase in knowledge. Higher positive scores indicate a larger increase in knowledge.

2. Change in General Interest in Learning About Neighborhood Health

   Time frame: Baseline, 30 minutes

   General interest in learning about neighborhood health will be measured through a single item asking, on a scale from strongly agree to strongly disagree, whether the participant would like to learn about liver cancer in their own neighborhood. Scores range from 1 to 5, with higher scores indicating more interest in learning about neighborhood health from a healthcare provider. Change in interest is measured by subtracting the baseline interest score from the post-intervention interest score. Change scores may range from -4 to 4, with positive scores indicating an increase in interest. Higher positive scores indicate a larger increase in interest.

3. Change in Interest in Learning About Neighborhood Health From a Healthcare Provider

   Time frame: Baseline, 30 minutes

   Interest in learning about neighborhood health from a healthcare provider will be measured through a single item asking, on a scale from strongly agree to strongly disagree, whether the participant would like to learn about liver cancer in their own neighborhood from their doctor. Scores range from 1 to 5, with higher scores indicating more interest in learning about neighborhood health from a healthcare provider. Change in interest is measured by subtracting the baseline interest score from the post-intervention interest score. Change scores may range from -4 to 4, with positive scores indicating an increase in interest. Higher positive scores indicate a larger increase in interest.

4. Change in Interest in Learning About Neighborhood Health From Other Sources

   Time frame: Baseline, 30 minutes

   Interest in learning about neighborhood health from other sources will be measured through a single item asking, on a scale from strongly agree to strongly disagree, whether the participant would like to learn about liver cancer in their own neighborhood from non-medical sources (e.g., website or brochure). Scores range from 1 to 5, with higher scores indicating more interest in learning about neighborhood health from other sources. Change in interest is measured by subtracting the baseline interest score from the post-intervention interest score. Change scores may range from -4 to 4, with positive scores indicating an increase in interest. Higher positive scores indicate a larger increase in interest.

5. Change in Interest in Discussing High Liver Cancer Risk With a Healthcare Provider

   Time frame: Baseline, 30 minutes

   Interest in discussing high liver cancer risk with a healthcare provider will be measured through a single item asking, on a scale from strongly agree to strongly disagree, whether the participant would be likely to discuss their liver cancer risk with a doctor if they learned they lived in a high-risk area. Scores range from 1 to 5, with higher scores indicating more interest in discussing liver cancer risk with a healthcare provider. Change in interest is measured by subtracting the baseline interest score from the post-intervention interest score. Change scores may range from -4 to 4, with positive scores indicating an increase in interest. Higher positive scores indicate a larger increase in interest.

6. Change in Outcome Expectancies for Learning About Neighborhood Health - Patient Behavior

   Time frame: Baseline, 30 minutes

   Patient outcome expectancies for learning about neighborhood health will be measured through a single item asking, on a scale from 0 (not at all) to 10 (very much), whether learning about neighborhood health will help the participant make health decisions. Higher scores indicate more positive expectations. Change in outcomes expectancies is measured by subtracting the baseline score from the post-intervention score. Change scores may range from -10 to 10, with positive scores indicating an increase in outcome expectancies. Higher positive scores indicate a larger increase in expectations.

7. Change in Outcome Expectancies for Learning About Neighborhood Health - Provider Behavior

   Time frame: Baseline, 30 minutes

   Provider outcome expectancies for learning about neighborhood health will be measured through a single item asking, on a scale from 0 (not at all) to 10 (very much), whether learning about neighborhood health will help the participant's healthcare provider make health decisions for them. Higher scores indicate more positive expectations. Change in outcome expectancies is measured by subtracting the baseline score from the post-intervention score. Change scores may range from -10 to 10, with positive scores indicating an increase in outcome expectancies. Higher positive scores indicate a larger increase in expectations.

8. Change in Intentions About Communicating With Healthcare Provider - Neighborhood Prevalence of Liver Cancer

   Time frame: Baseline, 30 minutes

   intentions about communicating with healthcare provider about neighborhood liver cancer will be measured through a single item asking, on a scale from very likely to not at all likely, how likely the participant is to discuss liver cancer in their neighborhood with their healthcare provider over the next 12 months. Scores range from 1 to 5, with higher scores indicating higher likelihood of talking to a healthcare provider. Change in intentions is measured by subtracting the baseline score from the post-intervention score. Change scores may range from -4 to 4, with positive scores indicating an increase in intentions. Higher positive scores indicate a larger increase in intentions.

9. Change in Intentions About Communicating With Healthcare Provider - Liver Cancer Screening

   Time frame: Baseline, 30 minutes

   intentions about communicating with healthcare provider about liver cancer screening will be measured through a single item asking, on a scale from very likely to not at all likely, how likely the participant is to discuss liver cancer screening with their healthcare provider over the next 12 months. Scores range from 1 to 5, with higher scores indicating higher likelihood of talking to a healthcare provider. Change in intentions is measured by subtracting the baseline score from the post-intervention score. Change scores may range from -4 to 4, with positive scores indicating an increase in intentions. Higher positive scores indicate a larger increase in intentions.

10. Change in Intentions About Communicating With Healthcare Provider - Liver Cancer Risk

    Time frame: Baseline, 30 minutes

    intentions about communicating with healthcare provider about liver cancer risk will be measured through a single item asking, on a scale from very likely to not at all likely, how likely the participant is to discuss their personal risk factors for liver cancer with their healthcare provider over the next 12 months. Scores range from 1 to 5, with higher scores indicating higher likelihood of talking to a healthcare provider. Change in intentions is measured by subtracting the baseline score from the post-intervention score. Change scores may range from -4 to 4, with positive scores indicating an increase in intentions. Higher positive scores indicate a larger increase in intentions.
