EXTERNAL EFFICACY INDEX, 100-PT SCALE
-------------------------------------------------------------------
USE WEIGHT VARIABLE VCF0009/VCF0009A/VCF0009B.
BUILT FROM VARS VCF0609 AND VCF0613.
To construct this variable, the component vars are first recoded as
follows: VCF0609,VCF0613: 1=0,2=100,3=50. The recoded values are
then totalled and divided by the number of valid responses. The
result is then rounded.
0. Least efficacious
.
100. Most efficacious
999. Not scored in both VCF0609 and VCF0613
