A measure of skin familiarity and its role in the early detection of skin cancer.
Skin self-examination (SSE) is promoted widely so that individuals will become familiar with their skin and be better able to identify suspicious changes earlier. However, individuals can also become familiar with their skin other than through purposeful SSE. In this article, we develop a measure of skin familiarity based on the density of spots on 14 different areas of the body. A factor analysis of the 14 body-area scores revealed that they could be grouped into four broad body regions (shoulders and back, front of legs, back of legs, and feet). Each total body score and body-region score has high internal consistency (Cronbach's alpha coefficients ranging from 0.79 to 0.93). Moreover, the scores correlate as expected with skin self-examination behaviors and other personal characteristics, indicating high construct validity. We consider the advantages that skin familiarity measures offer over the exclusive use of SSE measures in the assessment of early detection activities and discuss the direction of future research in this area.
