Development and preliminary validation of the Adolescent Psoriasis Quality of Life instrument: a disease-specific measure of quality of life in adolescents with psoriasis.

The preliminary form of the Adolescent Psoriasis Quality of Life instrument shows promising psychometric properties. It can be used in daily clinical practice and research to support a patient-centred approach and inform treatment planning. What's already known about this topic? Health-related quality of life (HRQoL) instruments should be targeted towards narrowly defined age groups, as life contexts of children, adolescents and adults may differ substantially. Dermatology-specific instruments have been used to measure HRQoL in adolescents with psoriasis, but it is not known whether these instruments accurately capture all relevant HRQoL aspects in adolescent psoriasis. Age-appropriate and psoriasis-specific instruments may be more sensitive for HRQoL issues experienced by this unique group. What does this study add? The Adolescent Psoriasis Quality of Life instrument represents the first age-appropriate and disease-specific instrument for measuring HRQoL in adolescents (12-17 years old) with psoriasis. It is intended for use in daily clinical practice to support dermatologists and other healthcare professionals in providing optimal care for adolescents with psoriasis.
