This research tests a novel source of resistance to social influence-the automatic repetition of habit. In three experiments, participants with strong habits failed to align their behavior with others. Specifically, participants with strong habits to drink water in a dining hall or snack while working did not mimic others' drinking or eating, whereas those with weak habits conformed.

Although screening facilitates prevention and early detection and is one of the most effective approaches to reducing cancer mortality, participation is low-particularly among underserved populations. In a large, preregistered field experiment (n = 7711), we tested whether deadlines-both with and without monetary incentives tied to them-increase colorectal cancer (CRC) screening.

Background: Financial incentives may improve health behaviors. We tested the impact of offering financial incentives for mailed fecal immunochemical test (FIT) completion annually for 3 years.
Methods: Patients, ages 50 to 64 years, not up-to-date with screening were randomized to receive either a mailed FIT outreach ( = 6,565), outreach plus $5 ( = 1,000), or $10 ( = 1,000) incentive for completion.

For hundreds of thousands of years, humans only communicated in person, but in just the past fifty years they have started also communicating online. Today, people communicate more online than offline. What does this shift mean for human social life? We identify four structural differences between online (versus offline) interaction: (1) fewer nonverbal cues, (2) greater anonymity, (3) more opportunity to form new social ties and bolster weak ties, and (4) wider dissemination of information.

Adherence to follow-up is low and patient-level barriers for suboptimal adherence have yet to be explored.
Objective: To characterize barriers for non-completion of diagnostic colonoscopy after an abnormal FIT reported by under- and uninsured patients receiving care in a safety-net health system.
Mailed outreach promoting colorectal cancer (CRC) screening with a stool blood test kit may increase participation, but magnitude and consistency of benefit of this intervention strategy is uncertain. Our aim was to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing mailed outreach offering stool tests to usual care, clinic-based screening offers on CRC screening uptake in the USA. We performed a systematic literature search of five databases for RCTs of mailed outreach from January 1980 through June 2017.

However, effectiveness of such practices has not been established. Our aim was to determine whether offering small financial incentives would increase colorectal cancer (CRC) screening completion in a low-income, uninsured population.

Objective: This study examines Twitter posts about e-cigarettes between 2008 and 2013 to gain insights into (1) marketing trends for selling and promoting e-cigarettes and (2) locations where people use e-cigarettes.
Methods: We used keywords to gather tweets about e-cigarettes between July 1, 2008 and February 28, 2013.
Objective: To examine behavioural intention to reduce soda consumption after exposure to the Choose Health LA 'Sugar Pack' campaign in Los Angeles County, California, USA.
Design: A cross-sectional street-intercept survey was conducted to assess knowledge, attitudes, health behaviours and behavioural intentions after exposure to the 'Sugar Pack' campaign. A multivariable regression analysis was performed to examine the relationships between the amount of soda consumed and self-reported intention to reduce consumption of non-diet soda among adults who saw the campaign.
Objective: To assess whether crowdsourcing is a viable option for conducting surveillance of point of sale (POS) tobacco marketing practices.
Methods: We posted jobs to an online crowdsourcing platform to audit 194 Florida licensed tobacco retailers over a 3-week period. During the same period, trained data collectors conducted audits at the same retail locations.
