Objective: Skin cancer incidence continues to rise as a tanned appearance remains desirable, particularly among young women. Fake tanning provides a tanned appearance without exposure to ultraviolet radiation. In order to advance our understanding of the factors that contribute to long-term behavior change, this study explores determinants associated with different types of tanning. Participants: The sample included 162 female students from the University of Adelaide, Australia, aged 18-26 years. Data were collected in July 2010. Methods: The current study measured differences in skin type, skin cancer knowledge, unrealistic optimism, appearance motivation, and sun-protective and sun exposure behaviors amongst outdoor tanners, fake tanners, and tan avoiders through an online survey. Results: Differences were observed for skin type, skin cancer knowledge, unrealistic optimism, sun protection, and sun exposure. Conclusions: A "one-size-fits-all" approach to skin cancer prevention may not be appropriate; type of tanning behavior may need to be considered in health promotion work.
