Relevanz demographischer und psychologischer Faktoren bei Pruritus

Relevance of demographic and psychological factors in pruritus



Pruritus ist ein häufiges Phänomen bei Patient:innen in der Dermatologie. Oft lässt sich das Ausmaß des Pruritus nicht allein über den Schweregrad der zugrundeliegenden Erkrankung erklären. Vor allem dann sollten auch demographische und psychologische Variablen als Moderatoren der Pruritusintensität in Betracht gezogen werden.


Gibt es Zusammenhänge zwischen Geschlecht, Alter, emotionalen und kognitiven Faktoren und der Pruritusintensität bei Patient:innen mit chronischem Pruritus (CP) und hautgesunden Kontrollproband:innen?

Material und Methode

Es wurden aktuelle Studien zu den oben genannten Moderatoren von Pruritus in Pubmed gesucht, zusammengetragen und deren Ergebnisse zusammengefasst.


Es zeigt sich, dass Frauen eine höhere Pruritusintensität angeben als Männer. Zudem sind negative Emotionen wie Angst, Ekel und Wut positiv mit Pruritus bei Patient:innen mit CP assoziiert. Auch gibt es Zusammenhänge zwischen kognitiven Faktoren wie Aufmerksamkeit, Katastrophisieren und Pruritus.


Die Zusammenhänge sowohl zwischen demographischen als auch psychologischen Faktoren und Pruritus sollten bei der Diagnostik und Therapie des Pruritus berücksichtigt werden. Eine psychologische Intervention als ergänzende Maßnahme sollte immer dann in Betracht gezogen werden, wenn Patient:innen Assoziationen zwischen psychischem Erleben und Pruritus berichten und/oder automatisch oder exzessiv kratzen.



Pruritus is a frequent phenomenon in patients in dermatology. The severity of pruritus often cannot be explained by the severity of the underlying disease or chronification processes alone. Especially then, demographic and psychological variables should also be considered as moderators of the intensity of pruritus.


Are there associations between sex, age, emotional and cognitive factors and pruritus intensity in patients with chronic pruritus (CP) and skin-healthy control subjects?

Material and methods

Recently published studies on the abovenamed moderators of pruritus were searched for in PubMed, collated and the results are summarized.


It was found that women reported a higher intensity of pruritus than men. In addition, negative emotions such as fear, disgust, and anger are positively associated with pruritus in patients with CP. There are also associations between cognitive factors, such as attention, catastrophizing, and pruritus.


The associations between both demographic and psychological factors and pruritus should be considered in the diagnostics and treatment of pruritus. A psychological intervention as a complementary treatment should be considered whenever patients report associations between psychological experiences and pruritus and/or automatic or extensive scratching.
