Brief Summary
Epidemiology seeks to improve public health by identifying risk factors for cancer and other diseases and conveying that information to relevant audiences (e.g., physicians, the public). The audience is presumed to understand and use that information to make appropriate decisions about lifestyle behaviors and medical treatments. Yet, even though a single risk factor can affect the risk of multiple health outcomes, this information is seldom communicated to people in a way that optimizes their understanding of the importance of engaging in a single healthy behavior. Providing individuals with the ability to understand how a single behavior (obtaining sufficient physical activity) could affect their risk of developing multiple diseases could foster a more coherent and meaningful picture of the behavior's importance in reducing health risks, increase motivation and intentions to engage in the behavior, and over time improve public health. The proposed study translates epidemiological data about five diseases that cause significant morbidity and mortality (i.e., colon cancer, breast cancer (women), heart disease, diabetes, and stroke) into a visual display that conveys individualized risk estimates in a comprehensible, meaningful, and useful way to diverse lay audiences.

Outcome Measures
Primary Outcomes (4)
Change From Baseline to 90-day Follow-up in Self Reported Weekly Minutes of Exercise
Baseline and up to 90 days
Difference in Gist Comprehension of Risk Information by Risk Display Format
* Risk display format = risk ladder, table, or text * Gist comprehension of risk information: being able to extract the bottom-line meaning of information provided by the website (e.g., if exercising decreased heath risk) * Measured by the sum of (4) questions coded as correctly comprehending risk information (1 point) or incorrectly comprehending risk information (0 points), with a total score range of 0=low comprehension to 4=high comprehension. Higher comprehension is considered a better outcome. * All comprehension questions have an additional "don't know" option, which is counted as incorrect. * To limit participant burden, the investigators assessed comprehension for diabetes only, instead of all diseases as planned. * Comprehension will not be assessed for people who report a history of diabetes because they are not given risk information.
Baseline
Difference in Verbatim Comprehension of Risk Information by Risk Communication Strategy
* Risk communication strategy = risk ladder, table, or text * Verbatim comprehension of risk information: being able to recall the exact information specific to diabetes risk and hours of recommended weekly physical activity * Measured by the sum of (3) questions coded as correctly comprehending information (1 point) or incorrectly comprehending information (0 points), with a total score range of 0=low comprehension to 3=high comprehension. Higher comprehension is considered a better outcome. * All comprehension questions have an additional "don't know" option, which is counted as incorrect. * To limit participant burden, the investigators assessed comprehension for diabetes only, instead of all diseases as planned. * Comprehension will not be assessed for people who report a history of diabetes because they are not given risk information.
Baseline
Difference in Self-reported Intentions to Engage in Physical Activity by Risk Display Format
* Risk display format = risk ladder, table, or text * Self-reported physical activity intentions is defined as intentions to engage in physical activity in the next 3 months * Measured as an average of three variables, each measured on a 5 point Likert Scale (range: 1=lower intentions to 5=higher intentions) * Higher intentions are considered a better outcome

Risk Display Format:Risk Ladder:Imagery Behavior:Exercise
EXPERIMENTAL* With help from a research assistant, participants complete the Risk Assessment App. The App asks demographic \& health questions. It then provides personalized risk estimates for participants' current activity level \& how it would change with regular exercise. * Participants take Baseline Survey 1. * Participants listen to an audio recording that guides them through a mental imagery activity. They write down an exercise goal \& are asked to practice the mental imagery twice a day for 3 weeks. * Participants take Baseline Survey 2. * Participants receive text messages reminding them to practice the mental imagery twice daily for 5 minutes each time (3 texts a week for 3 weeks). * Participants take surveys via text at the end of each week for 4 weeks. * 90 days post-baseline, participants complete a survey sent through the mail. * Participants may be contacted for another survey 1 year later.
