Interestingly, the behavioral response to itch (i.e. scratching) can be pleasurable, and patients often report scratch pleasurability (2). Scratch pleasurability may vary depending on the underlying etiology causing itch, however data on the pleasurability of scratching according to chronic itch diagnosis is unfortunately currently lacking. In a large study of atopic dermatitis and psoriatic patients, scratching was considered pleasurable in both diseases, and pleasurability correlated weakly with itch intensity in atopic dermatitis (3). Scratch pleasurability also differs in body locations and may be associated with topographical differences of itch (2, 4). Its characteristics amongst other common pruritic skin conditions have not been well studied. The purpose of this study was to examine differences in scratch pleasurability ratings amongst different pruritic conditions. A secondary outcome of this study was to examine the overall association of scratch pleasurability to itch intensity.
