Cannot be calculated
- Note: A DASH total score cannot be calculated if more than 3 items have not been answered. Total scores for the additional modules cannot be calculated if there are any missing items. Where 3 or fewer items have been missed, missing responses are replaced by the mean value of the responses to other items before summing.

calculate the optional four-item module score. All four questions must be answered in order to calculate the score. For each module, simply add up the assigned values for each response and divide by four (number of items); subtract one and multiply by 25 to obtain a score out of 100. Missing Items If more than 10 per cent of the items (that is ...
If less than 10% of items from Parts A and B (3 items or fewer) are left blank by the respondent, the mean average of the scores of the other items may be substi-tuted. For example, if a person responds with 28 “3’s” and two blanks, the missing values can be replaced by a value of “3.” If more than 10% are left blank, you will not be ...

A QuickDASH score may not be calculated if there is greater than 1 missing item. Quick DASH DISABILITY/SYMPTOM SCORE = (sum of n responses) - 1 x 25, where n is equal to the number of completed responses. n

- Comparison of The Dash and The QuickDASH
Internal consistency was very high for the DASH (median CA = 0.96, Table 4) and high for the QuickDASH (median CA = 0.90, Table 5). Both questionnaires reached very high levels of test-retest reliability (median ICCs = 0.92, Tables 4 and 5).
Face and Content Validity
High “face and content validity were the focus of the development stage of the DASH during which researchers, clinicians and patients helped in the selection of items and the wording of responses” (Kennedy et al. 2011). The appropriateness of the item content is obvious (Table 1) and meaning is easy to understand. Missing items are rare with the exception of item 21 about sexual activity, which is often left out. For the same reason, item 21 was not included in the QuickDASH (Kennedy et al. 2...
There is no gold standard for the assessment of upper limb symptoms and disability (criterion validity). However, “the obvious content validity of the used items and the numerous studies of the DASH give it a certain intrinsic validity” (Angst et al. 2011). There are numerous, (plus/minus well) validated instruments that were used for comparison of...
Reviewed data condensed a total of n = 492 correlation results for the DASH (Tables 6, 7, 8 and 9) and n = 107 for the QuickDASH (Table 10). From each report, only one set, if possible, the baseline score correlations were taken to avoid publication bias. Given several results (n) for the same score, the median of the correlations was calculated; i...
Discriminant construct validity was examined in various settings (Kennedy et al. 2011; Kennedy et al. 2013). For example: A DASH total score of 5–18 reflected no symptoms and disability/very mild severity, 12–36 mild, 23–44 moderate, 33–55 severe, and 55–60 very severe symptoms and disability depending on the study setting (data from 4 studies, sca...
Of the large number of studies reporting comparative responsiveness data, the most relevant are selected that compared the DASH to at least four other instruments or scales (Tables 11, 12 and 13). No study was found for the QuickDASH fulfilling that criterion. However, the almost identical construct of the short form will result in comparable data....
Normative data from a US population survey (n = 1706) have been published and allow comparison to patient data stratified by 10-years age group and sex (Kennedy et al. 2011). The general population mean DASH total scores were 7.4 for males and 12.0 for females (0 = best). For Norway, general population results are available from n = 992 DASH and 14...
The constructs of both tools are very similar, at first sight, especially when looking at the total scores (Kennedy et al. 2011; Angst et al. 2009; Kennedy et al. 2013): Construct convergence between the QuickDASH and the DASH was very high by median cross-sectional correlation of 0.97 (range 0.82–0.98, total n = 16 studies; Table 10). However, str...

Missing Items. If more than 10 percent of the items (that is, more than three items) are left blank by the respondent, you will not be able to calculate a DASH disability/symptom score.
