DASH Outcome Measure
Top Contributors -
The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire is a 30-item questionnaire that looks at the ability of a patient to perform certain upper extremity activities. This questionnaire is a self-report questionnaire that patients can rate difficulty and interference with daily life on a 5 point Likert scale..
The QuickDASH is an abbreviated version of the original DASH outcome measure In comparison to the original 30 item DASH outcome measure, the QuickDASH only contains 11 items It is a questionnaire that measures an individual’s ability to complete tasks, absorb forces, and severity of symptoms The QuickDASH tool uses a 5-point Likert scale from which the patient can select an appropriate number corresponding to his/her severity level/ function level
- The intended population for the DASH is any person with one or more upper extremity musculoskeletal disorders.
- The QuickDASH outcome measure is designed to be used on patients presenting with one or more disabilities of the arm, shoulder, and hand
DASH and QuickDASH Scoring Formula = ([(sum of n responses)/n] -1)(25) where n represents the number of completed items.
- DASH cannot be computed if greater than three items are missing.
- QuickDASH cannot be computed if greater than 1 item is missing.
Level of Disability
In both the DASH and QuickDASH a higher scores indicate a greater level of disability and severity, whereas, lower scores indicate a lower level of disability. The score on both test ranges from 0 (no disability) to 100 (most severe disability)
Additonal Optional Modules
The DASH and QuickDASH have two optional 4-item additional modules that can be used. The two optional additional modules are:
- Work Module - Used for workman compensation patients or those whose disability is affecting their ability to work
- Sports/Performing Arts Module - Used for Athletes and Musicians
The optional modules cannot be scored if an answer is missing.
|Reliability||ICC(2,1) = 0.96||ICC(2,1) = 0.90|
|Validity||Pearson r > 0.70||Pearson r > 0.70|
|Minimal Detectable Change (MDC)||12.75% - 17.23%||11.2%|
|Minimal Clinical Important Difference (MCID)||--------||8%|
(MDC)– the smallest amount of change that has to occur before the change can be considered a true change and not error
(MCID) – the amount of change in the score that has to occur before it signifies an important or beneficial difference in the patient’s condition.
- good responsiveness to self-rated changes before and after most arm, shoulder, and hand diagnoses and surgeries
- comparable responsiveness compared to other joint and disease-specific measures
- The DASH is available in 27 different languages. Also many of these versions have had or are in the process of being tested for their psychometric properties.
- The QuickDASH measure has more relative efficiency compared with the DASH Recent studies have also analyzed the reliability of a modified QuickDASH outcome measure, from a questionnaire into a visual analog version
