Syntax: 

^sf36v2^ , acute ref(population) fsc(year) details suffix(text) 

^acute^ specifies that the data refer to acute (1 week recall) form of the SF36 score 
        If this option is not specified, the score is used assuming that the data have
        been collected using the standard (4 week recall) form

^ref(^population^)^ can be used to specify the reference population and year
					default reference population is US 1998. The program supports
					US 1998 and JP 2002 reference populations 
		
^fsc(^year^) can be used to specify which factor score coefficients have to be used
             for the computation of the physical and mental component score. Default
			 coefficients are 1990 coefficients

^details^ will produce a table with the norms and factor score coeffients which
          have been used for the calculation			 

^suffix(^text^)^ allows use of suffixes to the variable names specified below
 
		  
Examples: 

^sf36v2^, ref(US 1998)  
^sf36v2^, acute d
^sf36v2^, ref(JP 2002) FCS(1995) suf(1y)                                                    


Note:
The variables containing the information for the calculation need first to be 
named as defined below. Suffixes may be specified as wished (see options above). 

PF01-PF10: Physical Functioning Questions 1-10
RP01-RP04: Role-Physical Questions 1-4
BP01-BP02: Bodily Pain Questions 1-2
GH01-GH05: General Health Questions 1-5
VT01-VT04: Vitality Questions 1-4
SF01-SF02: Social Functioning Questions 1-2
RE01-RE03: Role-Emotional Questions 1-3
MH01-MH05: Mental Health Questions 1-5
HT: Reported Health Transition


Treatment of Missing Data:
A scale score is calculated if a respondent answered at least half of the items in 
a multi-item scale (or half plus one in case of odd nr. of items)
