Does Itch Catastrophising Affect Men and Women with Chronic Itch Differently?

Itch is an unpleasant sensation that induces scratching and is often accompanied by psychological distress. Chronic itch, such as psoriasis or atopic dermatitis (eczema), has a lifetime prevalence of 22% and often carries a marked psychological burden. Catastrophising of itch symptoms can inhibit coping, increase scratching and lower mood, which maintains scratching and creates a vicious cycle. The relationship between sex, gender and chronic itch is not well understood. More broadly, sex and gender differences often go overlooked – this is called the gender data gap. Therefore, the first research question was, to what extent does catastrophising affect the quality of life of patients with chronic itch? The second research question was, to what extent is there a difference in how catastrophising affects the quality of life of men and women with chronic itch? 27 patients with chronic itch (psoriasis or atopic dermatitis) filled in the Pain Catastrophising Scale (PCS) adjusted for...Show moreItch is an unpleasant sensation that induces scratching and is often accompanied by psychological distress.

Therefore, the first research question was, to what extent does catastrophising affect the quality of life of patients with chronic itch? The second research question was, to what extent is there a difference in how catastrophising affects the quality of life of men and women with chronic itch? 27 patients with chronic itch (psoriasis or atopic dermatitis) filled in the Pain Catastrophising Scale (PCS) adjusted for itch and the Dermatology Life Quality Index (DLQI) online. Contrary to expectations, a simple linear regression analysis showed that catastrophising was not a significant predictor of quality of life. Furthermore, a multiple regression analysis showed that catastrophising does not affect the quality of life of men and women differently. Importantly, the results are limited by low sample size, lack of control variables and the use of convenience sampling. Further research into the relationship between itch catastrophising, quality of life and gender could greatly impact the lives of patients with chronic itch.Show less
