Abstract

Introduction: Skin diseases affect patients at any age, but as each period in life is different, tools used to assess quality of life impairment should be adjusted according to the particular age group. Adolescence is a unique time, when young individuals go through many changes, making them especially vulnerable to stress. Aim: Translation and validation of a Polish language version of the Teenagers Quality of Life (T-QoL) questionnaire. Material and methods: T-QoL was translated following international guidelines. A group of 34 dermatological patients, aged 12–19 years old, with various skin diseases were given the T-QoL as well as the CDLQI or DLQI to complete. They were also asked to complete the T-QoL questionnaire for the second time after 3–5 days. Statistical analysis of the results was performed. Results: The Polish version of T-QoL is internally consistent (Cronbach a 0.893 for the whole questionnaire). Moreover, it presents very good convergent validity (ICC = 0.864). No statistics significant differences between each question were noticed between the first and second time of completing the form. T-QoL scores correlated significantly with DLQI ( p = 0.008, r = 0.636) and CDLQI ( p < 0.001, r = 0.777) scores. Conclusions: The Polish version of the T-QoL questionnaire is a reliable instrument with adequate convergent validity, consistency and reproducibility. It can be successfully used to measure quality of life impairment among teenagers.
