Validity and reliability study of the Turkish version of the Hand20 questionnaire

Abstract

Background/aim: This study aimed to translate and validate the Turkish version of the Hand20 questionnaire. Materials and methods:Patients who had upper extremity involvement and stable symptoms for the previous 4 weeks in their upper extremities were included in the study. Patients who were illiterate or used a splint during the day were excluded from the study. Participants completed the Turkish version of the Disabilities of the Arm, Shoulder, and Hand (DASH-T) questionnaire once and the final version of the Hand20 questionnaire twice in a 7-day interval. Internal consistency and reliability of the questionnaire was assessed. Moreover, correlations between Hand20 and DASH-T scores were analyzed using Spearman's correlation coefficient.Results: A total of 104 patients participated in the study. The Turkish version of the Hand20 met the set criteria of reliability and validity. Internal consistency (Cronbach's alpha = 0.93) and test-retest reliability were excellent (r = 0.82). Hand20 showed a positive and statistically significant correlation with DASH-T (r = 0.76, P < 0.001). Conclusion:The results showed that the Turkish version of the Hand20 had excellent test-retest reliability and validity. As a result of this study, it was determined that Hand20 was a valid and reliable instrument to measure the upper extremity disabilities of Turkishspeaking patients.

Psychometric Properties of the Turkish Version of the JHand for the Patient-Oriented Outcome Measure for Patients with Hand and Elbow Disorders

“…The reason for this may be due to gender differences in the distribution of household chores within Turkey. Similarly, in the Turkish version study of Hand20, the researchers stated that most male patients did not answer questions such as those mentioned above (Tore & Oskay, 2019). Tore and Oskay (2019) also determined that participants between 15 and 80 years of age could easily complete the Hand20.…”

The current study also found that participants between 8 and 79 years of age had no difficulties in completing the Turkish version of the JHand.…”

“…Age, gender, educational status, occupation, work time, dominant extremity, and clinical information (diagnosis, affected extremity, and duration of symptoms) of the patients were recorded. All participants completed the Turkish versions of the JHand, DASH, and Hand20 questionnaires (Düger et al, 2006; Tore & Oskay, 2019). The Turkish versions of the DASH and Hand20 questionnaires were preferred because they are frequently used in the evaluation of upper extremity function, disability, and disorders (Düger et al, 2006; Tore & Oskay, 2019).…”

Although the completion time of the questionnaires varied by patient, each assessment took an average of 30 minutes.…”

“…Hand20 can be used for patients above 65 and under 18 (Suzuki et al, 2010). The validity and reliability of the Turkish version of the Hand20 questionnaire was conducted by Tore and Oskay (Tore & Oskay, 2019) and was shown to have excellent internal consistency (Cronbach’s α = 0.933) and test-retest reliability (ICC = 0.821). Hand20 showed a positive and statistically significant correlation with DASH-T (r = 0.761, p < 0.001) (Tore & Oskay, 2019).…”
