The DASH is scored in two components: the disability/symptom questions (30 item
> s in
the regular version and 11 items in the quick version of the DASH, scored 1-5)
and the optional high performance sport/music or work section (4 items, scored 
> 1-5).

Syntax: 
^dash^ varlist [if] [in], generate(newvarname) [optional] [quick]

        ^varlist^ must contain the 30 numeric variables to calculate the DASH s
> core.

        ^gen(^varname^)^ is used to specify where the score has to be stored.

        ^optional^ is specified if the optional component of the DASH has to be
>  calculated.
        This option requires ^varlist^ to contain 4 numeric variables.
                
        ^quick^ is specified if the quick version of the DASH has to be calcula
> ted.
        This option requires ^varlist^ to contain 11 numeric variables.

                  
Examples: 

^dash^ DASH1-DASH30, gen(DASH)  
^dash^ DASH*, gen(DASH)
^dash^ DASHop1-DASHop4, GEN(DASH_sport) optional
^dash^ DASH1-DASH11, gen(QuickDASH) quick
