Nonmedical information seeking amid conflicting health information: negative and positive effects on prostate cancer screening.

This study investigates the impact of seeking information about the prostate-specific antigen (PSA) test on men's PSA test use during a period of conflicting recommendations. Analyses used longitudinal survey data collected in 2005 and 2006 from a nationally representative sample of U.

S. males aged 40-70 years (n = 777). Cross-sectionally, nonmedical information seeking was significantly associated with increased odds of having a PSA test in the past year (Time 1 odds ratio [OR] = 9. 74, p < . 01, 95% confidence interval [CI] = 4. 37, 21. 70; Time 2 OR = 5. 78, p < . 01, 95% CI = 3. 17, 10. 55). However, lagged analyses showed that among men who had a PSA at Time 1, active seeking is associated with reduced odds of later having a PSA test (OR = 0. 33, p < . 05, 95% CI = 0. 13, 0. 85). Participants who had not had a PSA test in the past year very rarely sought information about PSA tests. Information acquisition in an environment of conflicting recommendations may influence adoption of cancer screening behaviors.
