The importance of assessing the readiness to change sun-protection behaviours: a population-based study.

The purpose of this study was to collect information that may be valuable in developing successful skin cancer prevention programmes. A random sample of 6000 adolescents and 4000 adults answered a questionnaire about sun-related issues. The response rate was 68%. Using sunscreen was the main sun-protection behaviour measured. Approximately 40% of adolescents and 30% of adults did not use any sun-protection strategy other than sunscreen. Readiness to change sun-protection behaviour was measured by assessing the stages of change modified from the Transtheoretical Model (TTM). Half of the participants were in the precontemplation stage of giving up sunbathing and avoiding the sun between 11 a.m. and 3 p.m. Attitude had the strongest association with being in the action/maintenance stages for all sun protection behaviours. A large proportion of participants were not ready to change their sun-protection behaviours, which highlights the importance of including motivational strategies when attempting to change sun-protection behaviours.
