        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
