OBJECTIVES: To perform a pilot testing of the translated and culturally adapted Polish pre-final  version of the DASH questionnaire in a population from a target setting. METHODS: Thirty patients (20 men), medium age 41.1 years (range 13 -79) from Rehabilitation Centre STOCER (Konstancin-Jeziorna) took part in pilot testing. The studied population was heterogeneous in terms of side affected (right: 13, left:13, both: 4), diagnosis (20 different diagnoses, most common - brachial plexus injury, n=6) and treatment (both conservative and surgical). Subjects completed questionnaires and were asked if there were questions that were difficult to respond or difficult to understand. After that each patients had to explain in his/her own words the meaning of five randomly chosen questions and their answers. We analyzed: number of missing items by question, number of missing items by patients and distribution of responses for each item. RESULTS: Understanding of randomly chosen questions and answers was appropriate. All items, except one, had high frequency of present answers (86.7% - 100%). Item 21 (sexual activity) was omitted by 60% of respondents. Number of missing items by patients ranged from 0 to 6. Five patients (16.7%) had more than 10 percent of the items left blank. Three from these persons were 60 years of age and over and could characterize with worse cognitive function. Fifteen items had responses with ≥ 35% frequency and three items (turning a key, recreational activities with force, recreational activities with moving arm freely) had responses with ≥ 50% frequency. CONCLUSIONS:  Patients had no complaints about understanding or difficulty of the adapted version of the questionnaire. Still, there were some items with missing answers (most often - sexual activity). Although, we provide some evidence of content validity, additional testing for the retention of psychometric properties of the translated questionnaire is recommended.
