Psoriasis Patients’ Knowledge about the Disease and Treatments

Table 3

Associations between demographic and clinical factors and PKQ by simple (unadjusted) and multiple (forward) (adjusted) linear regression analysis at T1.

	Patients’ level of knowledge (PKQ) (higher score indicates greater knowledge)
	Unadjusted Stdandard beta coefficient (𝑃 value)	Adjusted Stdandard beta coefficient (𝑃 value)
Sex (1 = men; 2 = women)	0.20 (0.001)	0.25 (0.000)
Cohabitation (0 = together; 1 = alone)	ns	ns
Education (1–5: higher score = higher level of education)	0.25 (0.000)	0.27 (0.000)
Age (years)	ns	ns
BMI (higher score = higher BMI)	ns	ns
PASI (higher score = more severe disease)	ns	0.19 (0.002)
PsA (1 = no; 2 = yes)	0.14 (0.023)	ns
Comorbidity (1 = no; 2 = yes)	ns	ns
Previous climate therapy (1 = no; 2 = yes)	0.28 (0.000)	0.29 (0.000)

BMI: body mass index, PsA: psoriasis arthritis, PASI: psoriasis area severity index, PKQ: psoriasis knowledge questionnaire, T1: before climate therapy, and ns: nonsignificant.
