Patient-reported outcome measurements rely on not only clinical status of patients but also their intellectual level. Hence, the age group in which a questionnaire is applied is important. In addition, the use of the questionnaires in the native language of the patients is of great importance for the evaluation of the spoken language speakers. The Hand20 Questionnaire is composed of 20 questions to measure upper extremity disability level. The questionnaire is illustrated and easily understood so that it can be easily applied to children and elderly people. The aim of this study was to test the validity and reliability of the Turkish version of the Hand20 Questionnaire. Translation and back-translation of the Hand20 were performed, according to Beaton guidelines. After any pathology, patients who had upper extremity involvement and stable symptoms for the previous 4 weeks in their upper extremity were included to study. Patients who were illiterate and using splint during day time were excluded from the study. They completed the Turkish version of Disabilites of the Arm, Shoulder and Hand Questionnaire (DASH-T) once and the final version of the Hand20 Questionnaire twice with a 7 days interval. Internal consistency (Cronbach s α) and reliability (test-retest reliability) of the questionnaire was assessed. Besides, correlations between Hand20 and DASH-T scores were analized by Spearman correlation coefficient. One hundred and four patients participated in the study. The Turkish version of the Hand20 met set criteria of reliability and validity. Internal consistency (Cronbach s α=0.93) and test-retest reliability were excellent (r=0.82). Hand20 showed positive and statistically significant correlation with DASH-T scores (r=0.76, p <0.001). Our results show that the Turkish version of the Hand20 has excellent test-retest reliability and validity. As a result of this study we determined that Hand20 is a valid and reliable instrument to measure upper extremity disabilities of Turkish speaking patients.
