Effects of tailored risk communications for skin cancer prevention and detection: the PennSCAPE randomized trial.

BACKGROUND

Prevention and early detection measures for melanoma, such as sun avoidance and skin examinations, are important, but are practiced inconsistently. In this replication of the Project SCAPE trial, we sought to determine whether tailored print materials were more effective at improving adherence than generic print materials for patients at increased risk of skin cancer.

METHODS

Participants were randomized to receive personalized mailed communications about their skin cancer risk and recommended sun protection, or generic mailings. Participants were Caucasian adults, at moderate or high risk for skin cancer, recruited in outpatient primary care. The main outcomes were overall sun protection behaviors and specific protective behaviors including use of sunscreen, shirt, hat, sunglasses, shade, and sun avoidance; recent sunburns; and skin self-examination and provider skin examination.

RESULTS

One hundred ninety-two (93.2%) subjects completed the study. Six outcome variables showed significant intervention condition effects in mixed effects models: overall sun protection behavior (P = 0.025); sunscreen use (P = 0.026); use of sunglasses (P = 0.011); sunburns in the past three months (P = 0.033); recency of last skin self-exam (P = 0.017); and frequency of skin exams by health care provider (P = 0.016).

CONCLUSIONS

Relative to generic communications, tailored risk communications resulted in improved adherence to six skin cancer protective behaviors, including a composite sun protection behavior measure, sunburns, and health care provider skin examinations.

IMPACT

Tailored interventions can be more effective in improving patient prevention behaviors than nontailored, generic information for patients at moderate to high risk of skin cancer.
