[Illness-related stress in psoriasis vulgaris. Validation of the "Psoriasis Daily Stress Inventory"].
OBJECTIVE
Illness specific stress plays an important part in the daily life of psoriatic patients. Until now for the measurement of relevant aspects of daily stress only the "Psoriasis Life Stress Inventory" (PLSI) of Gupta & Gupta exists; with the "Psoriasis-Alltagsstress-Inventar" (PAI), a German version of the PLSI is presented and its psychometric properties are discussed.


METHODS
385 in-patients completed the PAI. The internal validity was examined by factor analysis. Moreover, the correlations between the PAI total score and sociodemographic parameters (ANOVA) and extent of skin involvement (multiple regression) were determined.


RESULTS
The PLSI score proves to be sufficiently independent of age, sex, age at onset, and general extent of skin involvement. However, affections of the hands, the lower abdomen and the genitals show a strong influence on the total score. We found marked interrelations with the stigmatization feeling ("Questionnaire on Experience with Skin Complaints" QES, Schmid-Ott et al. 1998).


CONCLUSIONS
The results suggest that the PAI is a useful and psychologically relevant questionnaire for psoriatic patients.
