Reinvestigating the Perceptions of Annual Skin Cancer Screening Scale: a suitable measure for older adults.

Abstract

The Perceptions of Annual Skin Cancer Screening Scale (PASCSS) explains significant variance in whether people undergo annual clinical skin cancer screening beyond other relevant predictors. When developing the PASCSS, the author only tested its psychometric properties and validity with participants representative of the general USA population, despite the particular relevance of annual clinical skin cancer screenings to at-risk populations, namely, older adults. We reanalyze the PASCSS using a sample of older adults. We conducted a three-wave survey study (n = 237) with each wave separated by one week. Demographic information was recorded at Time 1. The PASCSS was administered at Time 2. Outcomes were measured at Time 3. The model fit of our confirmatory factor analysis met or closely approached traditional cutoffs, and each item loaded very strongly onto its respective latent factor. These PASCSS's dimensions together explained an additional 38% of variance in dermatologist screening and 37% of variance in any medical professional screening beyond our control variables (both P < 0.01). The dimension of Unknowledgeable was statistically significant in predicting dermatologist screening ( P = 0.03), whereas the three dimensions of Forget, Recommended, and Unknowledgeable were statistically significant in predicting any medical professional screening (all P < 0.05). Our results supported the psychometric properties and validity of the PASCSS, and we showed that the dimensions significantly relate to whether participants received a clinical skin cancer screening in the past year. The current investigation supports that the PASCSS is appropriate to administer to older adults.
