Subject:      [Q] about transforming scale

I need your help.
Someone serveyed about life-style on two type - 7-point category scale
and 6-point category scale.
He wants to separate the response into two category, and he has a prablem
how 7-point sclaing data is transformed.
He wants to know the formular and the scientific base of that.
He asked me this, and I think the formular is the following.
 
   D1 * 6/7 + 0.43
 
   (D1 = variable of 7-point category scaled data)
 
But the value '4' is a problem, and above formular is not complete.
So I ask your help.
 
Contents of Data are the following.
 
      data1(6-point)  +-----+-----+------+------+------+
                    negative     <-- | -->      affirmative
 
      data2(7-point)  +-----+-----+------+------+------+------+
                    negtive    <--|    so so    |-->   affirmative
 
      * Variable = 189
      * Observation = 6000
 
Please send me E-mail the following address with writing
the formular and the scientific ground about transforming of
7-point scaled data.
 
Thanks in advance.
