Abstract

OBJECTIVETo evaluate the intraexaminer and interexaminer reliability of low-cost commercial devices to measure skin tone, moisture, and oiliness; determine associations with the Fitzpatrick Scale; and compare results with those of widely used commercial equipment.METHODSResearchers bilaterally collected a total of 36 samples from 18 participants. For data acquisition, two experienced raters were considered for skin index assessment. Evaluations were conducted independently, with measurements taken at two different times with an interval between them, thus enabling intrarater and interrater reliability measures. The measurements were made with two low-cost devices and compared with those acquired using standard equipment for such analyses.RESULTSFor the intraexaminer reliability results, the authors observed intraclass correlation coefficient ranging from moderate to high reliability between these tools (0.747-0.971). Regarding interexaminer reliability, intraclass correlation coefficient ranging from moderate to high (0.541-0.939) were observed. For the results of the correlations, a moderate to a large association was observed for skin tone. However, a small association for moisture was observed among the tools.CONCLUSIONSEvaluations of skin tonality, oiliness, and moisture showed moderate to excellent intrareliability and interreliability. These methods can be applied in different environments, especially clinics, because of their low cost and ease of use. (AU)
