Subject   st: creating composite measures
Date   Thu, 22 Aug 2002 11:54:41 -0700

Can someone help me with creating a composite measure of prejudice from four individual variables in my data set which measure prejudice.
the variables are:

deasyblk: perception of blacks as easy to get along with
dwelfblk: perception of blacks as likely to be on welfare
dintlblk: perception of blacks as intelligent
drichblk: perception of blacks as rich or poor

the variables are distributed as follows:

. tab deasyblk

easy to get along |
w/blacks | Freq. Percent Cum.
---------------------+-----------------------------------
easy to get along w/ | 915 10.26 10.26

What I want to do is combine these four variables into one measure of prejudice, which will become a dependent variable in some of my models.

The only way I could think to do it was to create a new variable prejblk with numerical values 1 through 7 that equal the sums of the respective 1 through 7's
from my four variables...

gen prejblk=.
replace prejblk=1 if drichblk==1|dwelfblk==1|deasyblk==1|dintlblk==1
replace prejblk=2 if drichblk==2|dwelfblk==2|deasyblk==2|dintlblk==2
etc.

somehow this doesn't seem right, please help!

Seth
